  • 7. HRSG OPERATION AND MAINTENANCE SECTION 1: ENGINEERING FUNDAMENTALS 1. LEARNING OBJECTIVES • Explain the fundamental physical principals of: water to steam conversion, heat transfer and natural circulation for a heat recovery steam generator. • Explain basic functional concepts of the Heat Recovery Steam Generator (HRSG) boiler design 2. WATER TO STEAM The function of the boiler is to produce a specific amount of steam at a constant pressure and temperature from a specific amount of feedwater. This steam is used to drive the turbine. Water can exist in three physical states, solid, liquid or gas (vapor), depending on the corresponding pressure and temperature. Steam generation is only concerned with the liquid and vapor forms of water. Steam results from adding sufficient heat to water to cause it to vaporize or turn into a gas. This occurs in two steps: a. b. The addition of heat sufficient enough to raise the temperature of water to the boiling temperature. A continuing addition of heat to change to change the physical state of water from a liquid to a gas (steam) Thermal capacity (specific heat) is the quantity of heat required to produce a unit change in temperature. Water has a high thermal capacity. This means that a great amount of heat is required to cause a temperature change in water. Water cools slowly in the process of giving up absorbed heat. Specific heat is the term used in power generation for thermal capacity. Specific heat is the amount of British Thermal Units, BTU, required to raise the temperature of one pound of water one degree Fahrenheit (oF). It takes one BTU to raise the temperature of one pound of water one degree F. Other substances may require either more or less heat to raise one pound by one degree F. Enthalpy is the measure of the total stored internal energy of a substance, such as water or steam. Steam tables list the enthalpy in Btu/lb of saturated liquid (hf), and saturated and superheated steam at various pressures and temperatures. The Btu/lb Represents the amount of heat transferred to the water/steam from the combustion of fuels. Enthalpy changes are a function of temperature and pressure. The steam tables show the trends in BTU when going from a lower pressure to a high steam pressure. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-1
  • 8. HRSG OPERATION AND MAINTENANCE 3. STEAM GENERATION PROCESS Latent Heat of Fusion Latent heat of fusion is defined as the amount of heat required to melt one pound of ice at 32oF to one pound of water at 32oF. This latent heat or “hidden heat” produces a change in state of the water instead of a change in temperature. 144 Btu are needed to convert one pound of ice into one pound of water at 32oF at 14.7 psig or 29.92 “Hg, the normal atmospheric pressure or absolute pressure. This process is depicted in Figure 1. Figure 1: Latent Heat of Fusion Latent Heat of Vaporization Latent heat of vaporization is defined as the amount of heat required to change one pound of liquid water to one pound of steam (vapor). When additional heat is added to the water at its boiling point, the temperature of the water remains constant, but the physical state is changed. One pound of water at 212o F. which is the boiling point of water at 14.7 psig, requires 970 Btu to change into one pound of steam at 212o F. This process is depicted in Figure 2. Figure 2: Latent Heat of Vaporization/Condensation ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-2
  • 9. HRSG OPERATION AND MAINTENANCE Latent Heat of Condensation Latent heat of condensation, also shown in Figure 2, refers to the condition where a pound of steam at 212o F is cooled (heat is removed) to form a pound of liquid water at 212o F. The energy lost in going from a pound of steam to water is 970 Btu/lb. Sensible Heat Refer to Figure 3. When the flow of heat is not reflected in a temperature change (latent heat), it is absorbed in the fluid or substance and increases the kinetic energy of the molecules of the substance. This is called sensible heat. Water at 32o F will absorb 180 Btu of sensible heat per pound when raising the water temperature to 212o F. Figure 3: Sensible and Latent Heat ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-3
  • 10. HRSG OPERATION AND MAINTENANCE Heat Flow Heat is the flow of thermal energy. When heat is added or removed, temperature differentials are formed so that thermal energy can flow from one substance or area to another. Sensible heat and latent heat are merely two effects produced by heat, not different kinds of heat. When the flow of heat is not reflected in a temperature change (latent heat), it is absorbed in the fluid or substance and increases the kinetic energy of the molecules of the substance. 4. STEAM CHARACTERISTICS Quality of Steam The proportion, by weight, or “dry” vapor in a steam and water mixture is termed the quality of steam. Steam quality is expressed in percentages. If as quantity of steam contains 90% steam and 10% water vapor, the mixture has a quality of 90%. Saturated Steam Saturated steam is steam saturated with all the heat it can hold at the boiling temperature of water. Dry saturated steam vapor essentially contains very little moisture (dependent upon its quality), and is at saturated temperature for the given pressure. Its total heat content, or enthalpy, is equal to the heat of the liquids plus the heat of vaporization. Pressure and Temperature Relationship When water is heater to the boiling point in a closed vessel, the vapor released caused the pressure to increase in the vessel. With the increase in pressure, the boiling temperature of the water also increases. The temperature at which water boils at a given pressure is termed the saturation temperature. For each saturation temperature, there is a corresponding pressure called the saturation pressure. Figure 4 depicts the relationship between saturation temperature and saturation pressure. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-4
  • 11. HRSG OPERATION AND MAINTENANCE Figure 4. Pressure/Temperature Relation ship The Critical Point At 3208.2 psia with a corresponding saturation temperature of 705.5o F, water and steam properties are identical. In fact the terms “water” or “steam” no longer apply since the properties of the water and liquid are the same. Instead the term “working fluid” is used when temperature and pressure are above this critical point. Boilers designed to operate at pressures and temperatures below the critical point are called sub-critical boilers. Boilers designed to operate at pressures and temperatures above the critical point are called supercritical boilers. Superheated Steam Steam heated above its corresponding saturation temperature at a particular pressure is called superheated steam. Superheated steam contains no moisture, and will not condense until its temperature has been lowered to that of saturated steam at the same pressure. Superheating of steam takes place in the various superheater sections of the boiler. Steam must be superheated before it can be sent to the turbine or process steam headers to do useful work. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-5
  • 12. HRSG OPERATION AND MAINTENANCE Degree of superheat refers to the temperature difference in degree Fahrenheit between the steam at the superheater outlet, and its corresponding saturation temperature (steam drum outlet) at a given pressure. For example, consider a superheater outlet steam pressure of 72.5 psi and a superheater outlet temperature of 572o F. The corresponding saturation temperature at that pressure is 318o F. Therefore, the degree of superheat is 5720 F minus 318o F, equaling 254o F. It must also be recognized that there is a loss in steam pressure between the drum steam pressure and the superheater outlet pressure. Superheated steam has three advantages over steam that is not superheated: • It increases the efficiency of the turbine. • It prevents damage to turbine blades from condensation. • It is able to travel through long pipelines with little or no condensing. Departure from Nucleate Boiling There are two types of boiling that can occur in steam generators. Nucleate boiling – is the normal boiling process in a boiler in which water is raised to the boiling point, and individual steam bubbles form as water comes in contact with the hot tube surfaces. As these bubbles form and leave the heated surface, the cool water that remains (due to proper circulation) wets the tube surfaces, thus keeping the waterwall tube metal temperatures well within allowable limits. Film boiling – is an abnormal boiling condition and is present at times when insufficient water flow or circulation exists. When this type of boiling process takes place, steam bubbles form as water comes in contact with the hot tubes surfaces. They then collect and burst forming a film of steam which blankets the hot tube surface. Waterwall tube metal temperatures increase and tube damage can result. A term commonly used to describe this condition in DNB, or Departure from Nucleate Boiling. DNB can occur during periods of excessive firing rates if the circulation ratio or tube flow is not sufficient to carry away excess heat. Steam pockets form over large areas of the inner tube diameter, creating an insulating film barrier to normal heat transfer. The transition from Nucleate Boiling to DNB is shown in Figure 5. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-6
  • 13. HRSG OPERATION AND MAINTENANCE Figure 5: Nucleate Boiling and DNB Results of DNB can include: • • • • 5. Overheated tube failures Rapid accumulation of waterside tube deposits Uncontrollable drum level as large steam pockets are released Turbulence inside the drum can carry water out with the steam HEAT TRANSFER PRINCIPLES The process of transferring thermal energy can only occur if it originates from an area or material on one temperature to and area or material of a lower temperature. Heat transfer is vital to the operation of the power plant cycle and occurs in many locations throughout the plant. 6. HEAT TRANSFER MODES Conduction When heat passes through a solid object, quickly moving molecules in the hot portion collide with and give up some energy to slower molecules in the cooler portion. This type of heat transfer is called conduction. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-7
  • 14. HRSG OPERATION AND MAINTENANCE Radiation Heat transfer occurs via radiation when electromagnetic waves from a heat producing source strike a surface, and give up energy to the molecules in that surface. Burning fuels give radiant energy. Convection When a heated fluid or vapor moves to a cooler region by circulation resulting from density differences between the hot and cold areas within the fluid or vapor, this is called convection. 7. MAIN FACTORS AFFECTING HEAT TRANSFER Differential Temperatures (∆T) The temperature difference between a high temperature source and a low temperature source is called differential temperature. A higher ∆T will result in a greater amount of heat transfer. Thermal Conductivity Thermal conductivity is an indication of how well a material absorbs and transfers heat. A higher value of thermal conductivity means a material is capable of transmitting heat at a faster rate than a material with a low thermal conductivity. Surface Area Surface area is the area of a low temperature source that is placed in contact with a source of higher temperature. A larger exposed area will result in a higher heat Transfer Coefficient. The heat transfer coefficient is a constant factor, which mainly depends on the physical properties of the heat transferring mediums such as gasses, solids and metal tubes, and the gas velocity in the boiler. Materials are selected and arranged in the boiler according to their various heat transfer properties. Pinch Point The difference between the gas temperature leaving an evaporating section and the temperature at which boiling is occurring (saturated water temperature) is called a pinch point. The pinch point strongly influences the amount of heat transfer surface in the evaporating section. Current HRSG designs uses pinch points in the 15o to 25o F range. See Figure 16 for a graphic representation. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-8
  • 15. HRSG OPERATION AND MAINTENANCE Approach Temperature The approach temperature is the difference between the saturated-water temperature in an evaporating section and the incoming feedwater temperature. The approach temperature influences the amount of surface required for an economizer section, with exponentially increasing amounts required for very low approach temperatures. Current HRSG economizers have approach temperatures in the 15o to 25o F range. Many other operating conditions can occur at off-design points, including start-up. Some conditions will result in steaming at the exit of the economizer, such that it acts as an evaporative surface. See Figure 16 for a graphic representation. Materials Metals have good thermal conductivity. The number and arrangement of the tube assemblies placed in a boiler are selected to provide the proper tube surface area which is expressed to the hot solids/gasses so that the correct amount of heat is transferred to the water/steam to obtain design steam pressure and temperatures with design combustion temperatures. Fiberglass, silica block, and certain refractory compounds are used where heat transfer is not desired. These materials, called insulators, have low thermal conductivity and help to reduce the heat transfer. Improper insulation in the form of ash and /or dust and internal tube deposits can be very detrimental to boiler heat transfer, as indicated in Figures 6, 7, 8 and 9. Ash/dust deposits on the external surfaces of boiler tubes have lower thermal conductivity than the tube metal. A higher differential temperature is required to pass the proper amount of heat through the ash/dust to the water/steam inside the tubes. The reduction in heat flow from the tube to the boiler water/steam increases the average tube metal temperature, which can lead to tube failures from overheating. Temperature limitations for typical tube materials are shown in Table 1. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-9

BOILER WATER CIRCULATION Boiler circulation is defined s the movement of water, a mixture of steam and water, or steam through boiler tube circuits. There are two types of circulation: • Natural or “thermal” circulation • Forced or “controlled” circulation ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-11
  • 18. HRSG OPERATION AND MAINTENANCE Natural Circulation In natural circulation boilers, circulation is accomplished without the use of circulating pump. The density difference between steam and water (thermal head) is the driving force in a natural circulation boiler (Figures 10 and 11). Figure 10: Natural (Thermal) Circulation Cold side: The density of saturated water in the downtakes (also called downcomers) will range between 60 lb/ft3 and 30 lb/ft3, depending on the corresponding pressure and temperature in the boiler steam drum. Hot side: The steam/water mixture density in the waterwalls will be approximately 25 lb/ft3. Variations in boiler pressure have a lesser effect on the mixture density.

  • 19. HRSG OPERATION AND MAINTENANCE Figure 11: Circulation Schematic for Natural (Thermal) Circulation As boiler pressure increases, the difference between the densities of water and steam, which is the motive force for natural circulation boilers, becomes smaller (Figure 12). Thermal head differential is the resulting differential ranges between approximately 25 psi and 10 psi, with the greater differential being possible in lower pressure boilers (Figures 12 and 13).

  • 20. HRSG OPERATION AND MAINTENANCE Figure 12: Density of Water to Steam vs. Pressure In addition to the fact that there is less motive force in a higher-pressure boiler, there are also other factors in a natural circulation boiler, which oppose circulation. These are: • Friction between water and tube metal • Friction between water and scale deposits in tubes • Friction in tube bends • Friction in lower drum and headers • Friction around upper drum internals • Friction in the steam and water separating equipment ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-14
  • 21. HRSG OPERATION AND MAINTENANCE Figure 13: Typical Boiler Static Head – Constant Circulation Ratio of 4.0 Circulation Ratio Circulation ratio is defined as the weight of water entering the downcomer, divided by the weight of steam in the water/steam mixture leaving the water wall tube circuits. Because circulation is dependent on the thermal head, which is dependent on boiler pressure, the flow of water into the downcomer increases as load decreases. At low loads of 50% of Maximum Continuous Rating (MCR) or less, the circulation ratio will be much higher since there is less steam being generated. Natural Circulation boilers are generally designed for a circulation ratio of “5” equaling a circulation ratio of 5 to 1. For example, for every 25-lb. Of water entering the downcomer, there could be as much as 5 lb of steam leaving. 9. HEAT RECOVERY STEAM GENERATOR The following material was copied from pages 8-30 to 8-35 of the Combustion Fossil Power text. A Heat Recovery Steam Generator (HRSG) is used to recover heat that otherwise would be lost in the exhaust from a gas turbine. This heat is then used to generate steam that will drive a steam turbine or be used in a process. Typically, the addition of an HRSG and a steam turbine boosts total output of electricity by 30 percent or more over the traditional gas turbine operating in a single cycle mode. Efficiency increases with the increased output. Gas turbines have been widely used to provide standby or peaking power for electric utilities, or for unattended service in remote locations. As described in Chapter 1, the thermal efficiency is low because of high exit-gas temperatures (800 to 1000o F, or 425 to 540oC) and high excessair levels (220 to 300 percent) in the combustion products. The thermal energy remaining in the ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-15
  • 22. HRSG OPERATION AND MAINTENANCE exhaust gas can be recovered in a heat-recovery boiler to produce additional electricity using a steam-turbine generator. The combined output of electricity from the gas turbine and the steam turbine is 30 to 50 percent greater than that obtained from the gas turbine alone, with no additional fuel input. Combined-cycle power plants for industrial power-generation application have much higher thermal efficiencies than conventional steam power plants with the same steam conditions. In general, the high thermal efficiency of a combined-cycle plant can be economically exploited if liquid or gaseous fuels are readily available and the unit can be operated continuously or operated on an interruptible basis at least 50 percent of the time at full power. Chapter 1 of the Combustion Fossil Power text identified the four major classifications of combined cycles and their associated heat rates. The two most commonly used cycles for industry employ unfired or supplementary fired heat-recovery steam generators (HRSG’s). Supplementary fired heat-recovery steam generators use firing equipment located in the exhaust gas stream in the boiler inlet transition duct. Since gas-turbine exhaust contains 75 to 80 percent of the oxygen normally found in atmospheric air, fuel may be burned without the need for additional fresh air. By using duct burners, gas-turbine exhaust temperatures can be increased to 1500 to 1600oF (815 to 870oC) with a consequent reduction in the oxygen content of the exhaust gas from 15 percent to 11 percent. Supplementary firing generally doubles the steam output of the heat-recovery boiler by providing a mechanism for varying steam production and matching process-steam demand, independent of the gas-turbine electricity production. Most applications of HRSG’s to gas-turbines of greater than 20MW generate steam at two or three pressure levels. High-pressure steam (600 to 1800 psig, or 4.1 to 12.4 MPa gage) usually drives a steam-turbine generator. Intermediate-pressure steam (200 to 400 psig, or 1.4 to 2.8 MPa gage) is used for process steam in a plant or is injected into the gas-turbine combustor to reduce NO, emissions. Low-pressure steam (5 psig to 120 psig, or 35 to 825 KPa gage) is used for plant processes or feedwater heating in a de-aerator. An increasing number of installations induce intermediate-pressure steam for additional power recovery in the low-pressure stages of an enhanced power output when plant steam demand is low, but electrical demand is high. The heat-recovery steam generator may also incorporate additional water-heating sections for condensate preheating or for high-temperature water for fuel heating or other plant processes. In some locations, air-quality authorities have imposed very stringent requirements for NOx emissions from gas turbines. In many cases, these requirements virtually mandate the use of NOx reduction catalysts in the turbine exhaust steam. These catalyst assemblies operate in a narrow temperature range that is lower than the turbine exhaust-gas temperature. The presence of an HRSG is an asset in the strategy to control emissions since the NOx reduction catalyst may be located in the appropriate temperature zone between sections of heatexchange surface in the boiler. Steam-Generator Designs The basic principles for selecting heat-recovery steam-generating equipment are similar to those for conventional utility and industrial boilers. However, the designer must be aware of the entire system arrangement in order to integrate the steam generator properly within the overall plant. Although cycle efficiency and economics generally determine the basic cycle conditions, the designer is typically faced with a matrix of conditions, which determine the optimum design. These conditions include a wide range of thermal performance parameters, dictated by varying ambient conditions and steam load requirements, limitations on capital cost, and restrictions on available space. In pursuing a solution to the demands of a specific application, three aspects ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-16
  • 23. HRSG OPERATION AND MAINTENANCE of the boiler design process dominate: (1) extensive use of externally finned tubing for maximum convective heat recovery, (2) an emphasis on low gas-side pressure loss to limit the gas-turbine fuel-rate penalty associated with increased backpressure on the gas turbine, and (3) distribution of heat-recovery surface in multiple sections to achieve optimum heat transfer at each temperature level through the boiler. Figure 14: Vertical, Unfired Steam Generator for Recovery of Heat from Gas Turbine Exhaust Boiler Configuration Waste-heat boilers in gas-turbine exhaust service can be configured with gas flow in the horizontal or vertical direction. Vertical gas-flow units permit an arrangement of equipment in the exhaust flow path that occupies less floor space but requires extensive steel support structure. Horizontal gas-flow units generally cover a greater plan area, but afford much better access for maintenance of boiler parts, duct burners, catalyst elements, and other equipment that may be associated with the HRSG. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 1-17
  • 24. HRSG OPERATION AND MAINTENANCE Boilers with vertical gas flow usually employ horizontal tubes connected by return bends with the tubes supported at several locations along the length of the tube my tube sheets, as illustrated in the figure above. Most of these applications require a circulating pump in the steam-generating sections of the boiler. The circulating pump ensures uniform distribution of water to multiple parallel steam-generating circuits. Pumps are usually sized to maintain a circulation ratio of 4 to 1 at the maximum steaming condition. Boilers with horizontal gas flow use vertical tubes connected to headers at the top and bottom, as seen in the following figure. The tube and header assemblies may be either top-supported or bottom-supported. Although the tubes are self-supporting in the vertical direction, lateral restraints are required to control gas-flow-induced vibrations. Natural circulation in the steamgenerating sections provides high circulation ratios without the use of pumps.

There are ten discrete heat-exchange sections distributed in descending order based on the gas temperature available and the fluid temperature requirements. The two critical temperature differences that influence the amount of heat-transfer surface and the overall steam generated at each pressure level are the: • Pinch point: The difference between the gas temperature leaving a evaporating section and the temperature at which boiling is occurring (saturated-water temperature). • Approach temperature: The difference between the saturated-water temperature in an evaporating section and the incoming feed-water temperature. The pinch point strongly influences the amount of heat-transfer surface in the evaporating section. Current HRSG designs use pinch points in the 15 to 25oF (8 to 14oC) range. In general, these boilers have 50 percent more surface in the evaporating section than boilers with pinch points of 40 to 50oF (22 to 28OC). The approach temperature also influences the temperatures. Current HRSG economizers have approach temperatures in the 15 to 250oF (8 to 14oC) range at the design point. Many other operating conditions can occur at off-design points, including start-up. Some conditions will result in steaming at the exit of the economizer, such that it acts as evaporative surface.

  • 27. HRSG OPERATION AND MAINTENANCE Specific provisions to accommodate steaming at levels up to 5 percent of total flow in an economizer include: (1) careful control of water distribution in the last downflow passes of the economizer to cause that portion of the economizer to behave as a forced-circulation evaporator, or (2) configuring the last few passes of the economizer as entirely upflow, with relief by natural circulation into the steam drum. The triple-pressure HRSG temperature diagram shown in Figure 16 illustrates the distribution of heat-exchanger sections and the side of each evaporating bank section. Approach temperatures are illustrated as the difference between the water temperature leaving the last section of each economizer and the saturated-water temperature. Note that the high-pressure economizer is divided into three separate sections to provide appropriate temperature zones for the intermediate-pressure superheater, evaporator and economizer. Typical Construction Features The triple-pressure HRSG shown in Figure 17 illustrates equipment normally included in the scope of supply of the boiler supplier: • Expansion joint at gas-turbine exhaust interface • Single-blade exhaust diverter valve bypass stack with silencer • Inlet transition duct with flow corrective devices • Duct burner • Heat-recovery steam-generator modules steam drums • Access ladders and platforms • Exhaust stack Insulation is placed on the inside of all duct sections and boiler casing sections, thereby allowing the use of carbon steel casing plate and stiffeners, and minimizing the thermal growth of the overall boiler structure. A system of internal liner plates protects the insulation from gas flow. These plates are segmented for individual thermal expansion and overlapped in the direction of gas flow. All boiler pressure parts are supported in ways that allow complete freedom for thermal expansion relative to the casing and support structure.

  • 28. HRSG OPERATION AND MAINTENANCE Fired Steam Generators Supplied with Gas Turbine Exhaust Normally containing 75 to 80 percent of the oxygen found in free atmospheric air, gas-turbine exhaust can concurrently supply to the furnace of a steam generator both sensible heat and oxygen for the combustion of a fuel. The design and operation of such boilers vary considerably, depending upon the ratio of the total exhaust flow to the amount necessary for oxidizing the supplementary fuel needed for a given evaporation. Combustion air preheaters are not used because of the already high level of preheat represented by the 700o to 900oF (370oF to 480OC) temperature of the exhaust gases. Supplementary-fired steam generators (Fig. 24) using most of the oxygen in the turbine exhaust are of the same design and size as units using outside air through forced-draft fans. The stack temperature of such a unit can be dropped economically to within 100o F (55o C) of the incoming feedwater temperature. Since the boiler is sized for a flue gas weight based on fresh air firing, a portion of the gas turbine exhaust is by-passed. This portion of the exhaust is cooled by passing over a separate steam generating bank, to the same temperature as the gasses passing through the boiler, and then proceeds to the final heat recovery in the economizer. In such a cycle, gas turbine and boiler size must be matched closely to obtain a high ratio of feedwater flow to the gas-turbine exhaust flow. Because all gas-turbine/boiler applications involve the recovery of sensible heat, the usual concept of boiler efficiency loses its significance. Customary practice therefore is to evaluate performance of combined-cycle boilers on the basis of stack temperature. The overall station heat balance is determined using the calculated value of fuel fired in the boiler (rather than boiler efficiency as such), in addition to the fuel fired in the gas turbine.

  • 29. HRSG OPERATION AND MAINTENANCE SECTION 2: HRSG SYSTEM DESCRIPTION 2.1 LEARNING OBJECTIVES • Draw a simplified functional diagram of the HRSG, labeling the major components. • Describe the purpose and function of the major components. 2.2 INTRODUCTION (Refer to Pressure Part Diagram, Figure 2-3) This section provides a brief description of the components that make up the Heat Recovery Steam Generator (HRSG). The HRSG consists of three boiler systems at different pressure levels, high pressure (HP), intermediate pressure (IP), and low pressure (LP) and a Reheater. The water/steam and the exhaust gas flow paths are described below, starting from the inlet and following the fluid flow path. Each pressure stage consists of an economizer, evaporator and superheater. The Feedwater is heated in the economizer and fed to the drum. From the drum, water is fed into the evaporator, where a portion is evaporated. The resulting water-steam mixture returns to the drum, where the mixture is separated by means of separators. The saturated steam is fed into the superheater. The water/steam and the exhaust gas flow paths are described in the next section starting from the inlet and following the fluid flow path. The heat-absorbing sections of the HRSG are made up of shop-assembled pressure part modules. These modules can be shipped by truck, rail or barge. Each module is properly braced for shipment. The HRSG finned tubing is made by helically winding solid or serrated fin stock to the walls of bare tubing by means of a low penetration, high frequency resistance welding process. The HRSG evaporator circuits incorporate large steam drums to reduce the potential for water surges normally encountered during cold starts. Dedicated downcomers are used to ensure a proper circulation in each of the evaporator circuits. 2.3 HIGH PRESSURE WATER/STEAM FLOW PATH HP feedwater is supplied to the HP pressure section via the HP stage of the feedwater pump, which extracts feedwater from the Deaerator Storage Tank. The HP Economizer section functions to raise the boiler feedwater to a suitable approach temperature. After passing through the feedwater control, check and stop valves, the HP feedwater enters the HRSG at HP Economizer 4. The water then flows through HP Economizer 4, HP Economizer 3, HP Economizer 2, and then through HP Economizer 1. After leaving HP Economizer 1, the water enters the HP Steam Drum through one feedwater inlet nozzle and continues on to HP Evaporator. Natural circulation is maintained in the HP Evaporator by means of downcomers, which feed the water from the drum through distribution manifolds to the lower evaporator headers. Steam is generated and flows upward in the ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 2-1
  • 30. HRSG OPERATION AND MAINTENANCE evaporator tubes. The saturated water/steam mixture is conducted from the upper HP Evaporator headers to the HP Steam Drum through risers. The saturated steam is separated from the saturated water/steam mixture by the drum internals (centrifugal separators, corrugated dryers, and dry box) and then exits the top of the HP Steam Drum through the saturated steam outlets. ( A typical section of steam drum internals is shown in Figure 2-1) The saturated steam leaving the drum passes through HP Superheater 3 and HP Superheater 2. After leaving HP Superheater 2, the steam passes through two HP Desuperheaters in parallel. After leaving the HP Desuperheater, the steam flows through HP Superheater 1. The steam leaves HP Superheater 1 through connecting links where it is combined into the HP Main Steam line. 2.4 REHEATER STEAM FLOW PATH After combining with the IP steam, the cold RH enters the HRSG through Reheater 2. The steam then passes through two RH Desuperheaters in parallel into Reheater 1. The steam leaves Reheater 1 through connecting links where it is combined into the hot Reheat Steam Line. 2.5 INTERMEDIATE PRESSURE WATER/STEAM FLOW PATH After passing through the feedwater control, check and stop valves, the IP feedwater enters IP Economizer 1 then enters the IP Steam Drum through the feedwater inlet nozzle. This flow continues through the IP Evaporator. Natural circulation is maintained in the IP Evaporator by means of downcomers, which feed the water from the drum through distribution manifolds to the lower evaporator headers. Steam is generated and flows upward in the evaporator tubes. The saturated water/steam mixture is conducted from the upper IP Evaporator headers to the IP Steam Drum through risers. The saturated steam is separated from the saturated water/steam mixture entering the steam drum by the drum internals (centrifugal separators, corrugated dryers, and dry box) and exits the top of the IP Steam Drum through saturated steam outlets. The saturated steam leaving the drum passes through the IP Superheater. The steam leaves the IP Superheater through connecting links where it is combined into the IP Main Steam Line. A portion of the IP Steam can be used as pegging steam for the external deaerator. The IP steam passes through non-return and stop valves and then combines with the cold reheat steam. 2.6 LOW PRESSURE WATER/STEAM FLOW PATH The LP Feedwater takes suction from the Dearerator Storage Tank. The LP Feed water from terminal point (TP-7) passes through the flow orifice, control valve, stop check valve and block valve and enters the LP Drum through the feedwater inlet nozzle. A separate Condensate Feed flows through the Condensate Preheater and on into the External Deaerator Tank. A portion of the water from the Preheater outlet is taken to the Preheater Recirculation Pump suction. It then is being recirculated and mixed with the feedwater entering the Preheater inlet nozzle to increase the temperature of the incoming feedwater prior to entering the External Deaerator. Natural circulation is maintained in the LP Evaporator by means of downcomers, which feed the water through distribution manifolds into the lower evaporator headers. Steam is generated and flows upward in the evaporator tubes. The saturated water/steam mixture is conducted from the upper LP Evaporator headers to the LP Drum through risers. The saturated steam is separated ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 2-2

HRSG OPERATION AND MAINTENANCE from the saturated water/steam mixture entering the steam drum by the drum internals (corrugated dryers, and dry box) and exits the top of the LP Drum through saturated steam outlets. The saturated steam leaving the drum passes through the LP Superheater. The steam leaves the LP Superheater through connecting links where it is combined into the LP Main Steam line. 2.7 GAS SIDE FLOW PATHS The exhaust gas that enters the HRSG will pass by the pressure part sections of the HRSG, heating the steam or water inside the tubes. The exhaust gas will pass across the pressure part sections in the following order: HP Superheater 1 - Reheater 1 - HP Superheater 2 - Reheater 2 - HP Superheater 3 - HP Evaporator 1 – HP Evaporator 2 The gas then passes across the remaining pressure parts sections in the following order: IP Superheater - HP Economizer 1 - LP Superheater - HP Economizer 2 - IP Evaporator - HP Economizer 3 - IP Economizer 1 - LP Evaporator - HP Economizer 4 - Condensate Feedwater Preheater. The exhaust gas will leave FW Preheater and exit the HRSG through the main exhaust stack. Some changes may occur in the pressure sections such as surface oxidation. In addition, normal operation of the boiler may result in some bowing of the tubes due to normal manufacturing tolerances. Both of these conditions are considered normal and are expected. 2.8 SCR – SELECTIVE CATALYTIC REDUCTION SYSTEM (Not used at Nubaria) N/A 2.9 START-UP VENTS The HP main steam outlet piping incorporates a remotely operated vent valve at a location just upstream of the main steam outlet check valve. This valve is used to vent air and non-condensables from the system during start-up and to relieve excess steam pressure during steam system transients. 2.10 SKY VENTS The sky vents system consists of a shut off manual valve, a control valve, the flow orifice and the steam silencer. Whenever the control valve opens, steam releases into the atmosphere. The flow orifice determines the steam flow to be added to the total steam flow for drum level control. The steam silencer reduces the noise through this vent line. 2.11 MAIN STEAM TO COLD REHEAT BYPASS (Not used at Nubaria) N/A ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 2-3

  • 34. HRSG OPERATION AND MAINTENANCE 2.15 OVERALL PROJECT A gas turbine combined with a triple-pressure HRSG with reheat and HP/IP/LP steam turbines form the combined cycle plant at the Nubaria Power Station. The HRSG utilizes the hot exhaust gas from the gas turbine to generate steam in three cycles: high pressure, intermediate, and low pressure. Steam produced is directed to the steam turbine. The HRSG is also equipped with a reheater section to reheat steam, which has passed through the HP turbine and direct it to the IP turbine. The Predicted Performance data provided at the end of this section addresses multiple operating conditions for the HRSG. Ambient conditions ranged from a modest 15 °C (59 °F) on up to 40 °C (104 °F) were reviewed. Maximum HP steam flow 71.19 Kg/s occurs at 129.2 bar and 567.7 °C. 2.16 SCHEMATIC OVERVIEW Figure 2-3 (At the end of this section) provides an overview of the fluid flow paths, both series and parallel, which integrate the HRSG into the larger system of separators, coolers, preheaters, pumps, and turbines. Rather than simply being a radiator, the integration of this complex heat transfer system results in one of the most cost effective and efficient electric power production units in the world. 2.17 GAS SIDE FLOW PATHS Gas Turbine exhaust gas enters the HRSG at approximately 3,465,000 #/hr at 1121 °F.

HRSG OPERATION AND MAINTENANCE SECTION 3: AUXILIARY SYSTEMS AND EQUIPMENT 3.1 LEARNING OBJECTIVES Describe the purpose, function and basic operation of the auxiliary system and components of the HRSG. 3.2 SAFETY VALVES Safety valves are devices that protect the steam and water circuits of the boiler against accidental over pressurization. They provide the final protection against pressure part damage when other means, such as control and interlock systems fail or cannot react fast enough. The A.S.M.E. Boiler and Pressure Vessel Code states that safety valves are required on every pressure vessel. The boiler code also requires that the safety valves have a total steam relieving capacity at least equal to the rated full load steam flow of the boiler. 3.2.1 Description Each safety valve consists of a valve disc and seat, which form the seating surfaces. The disc is attached to the valve stem, called spindle, which extends up through the valve body. See Figure 3-11. A spring is used to provide the necessary force to hold the disk against the valve seat until the steam pressure below the disk forces the valve open, overcoming the spring compression. The compression screw is used to adjust spring compression or the popping pressure at which the safety valve opens. Upper and lower adjusting rings are provided inside the valve body near the valve disc and seat. The upper adjusting ring is used to adjust the “blowdown” or the difference between the valve opening and closing pressure. The lower adjusting ring is provided to obtain a quick popping action and to cushion the closing of the valve. ALSTOM Power Copyright 2004 Santan Expansion Project Revision: 0 06/02/04 3-1

  • 42. HRSG OPERATION AND MAINTENANCE 3.2.2 Hydrostatic Test Plugs and Valve Gags Hydrostatic test plugs are installed between the valve disc and seat for two purposes. • To protect the valve seating surfaces during shipment. • To increase spring compression to prevent the valve from opening during initial hydrostatic testing. These plugs must be removed before initial valve setting during boiler start-up. Safety valve gags prevent the safety valve from opening during hydrostatic tests and are also used when setting safety valves and when making valve adjustments. A typical Safety Valve Gag is shown in Figure 3-2. NOTE: Under no circumstances should gags be left on during normal operation.

  • 43. HRSG OPERATION AND MAINTENANCE 3.2.3 Safety Valve Operation Steam pressure in the drum or header is applied directly to the valve disc through the inlet nozzle. When the popping pressure is reached the steam pressure overcomes the force of the spring and the disc and spindle is pushed up opening the valve. This is called the “full life” position. The reaction force of the steam blowing between the disc and the seat holds the valve open. With the safety valve open the system steam pressure drops. When the spring pressure overcomes the steam pressure, the disc and spindle return to the closed position. Figure 3-3 shows a typical safety valve in both the open and closed positions.

  • 48. HRSG OPERATION AND MAINTENANCE 3.3 WATER LEVEL GAUGE The primary function of water gauges and indicators is to provide the operator with a readily visible means of monitoring the water level within the steam drums at all times. Proper water level in steam drums is crucial during HRSG operation for the following reasons: • Too low a water level in a steam drum may cause reduction and/or loss of circulation in the tube circuits. • Too high a water level will reduce the effectiveness of the steam separators and dryers in the drums causing water carry-over to the superheating tube assemblies. 3.3.1 Location The water gauge level indicator is attached to the end of each steam drum to allow visual monitoring of the steam drum water level. In accordance with the A.S.M.E. code for power boilers, a minimum of two (2) steam drum level indicators must be in service on the boiler steam drum at all times. In addition to the water level gauge, three level transmitters are also attached to the steam drum. 3.3.2 Description Normal operating water level in the steam drum is approximately the centerline of the drum. (See Figures 4-3, 4-4 and 4-5 for Drum Level Setpoints for the LP, IP, and HP Drums). The centerline of the gauge glass is located slightly below the normal water level (NWL) to correct for sub-cooling effects during operation. The gauge assembly typically consists of a steel body with flat glass faces. The tie-bar (necessary on only one end of these drums) includes upper and lower valves, which provide isolation of the water gauge for servicing and a connection for draining. This type of gauge requires a rear positioned illuminator. The illuminator is a device, which provides an electric lamp source for better viewing. The centerline of the water gauge glass is location slightly below the normal water level to correct for sub cooling effects during operation. Sub cooling is a condition when the water in the lower gauge glass connection is cooler than the water in the steam drum. The level in the water gauge will be lower than the actual level in the drum because the density in the gauge is greater than that of the steam drum. Placing the gauge centerline below the drum centerline compensates for the density difference between the water gauge and the steam drum. The water gauge body is attached vertically to a support column, which is connected to the water and steam sides of the steam drum through connections provided on the end of the steam drum. The water gauge is assembled from glass along with the necessary gaskets for sealing against drum pressure and temperature.

  • 49. HRSG OPERATION AND MAINTENANCE The drum water level is visible in the water gauge at all times, no matter how rapidly the water may rise or fall within the steam drum. This enables the operator to take an accurate reading at any time during operation. 3.3.3 Operation Water gauges use the principle of liquid seeking a level between two connected vessels. The top of the gauge glass is connected to the steam space of the drum. The bottom of the gauge connection is below the normal water level of the drum. This arrangement will allow the liquid in the gauge to rise to a level indicative of the level in the steam drum. Water in the gauge glass is cooler than water in the vessel and is denser. This results in a gauge water level, which is lower than the true water level in the vessel. Although this is compensated for, the operator must be cautioned to look for any other conditions, which may also lead to variations in gauge levels, such as: • Plugged connection lines that will cause abnormal level readings, which can be corrected by proper lowdown. • Steam leaks that will reduce the pressure in the steam space of the gauge and will cause the water level in the gauge to rise. Steam leaks should be properly corrected to prevent damage to the gauge gasket-seating surface as well as to prevent false readings. 3.3.4 Water Gauge Blowdown The procedure for water gauge blowdown is as follows: a. b. c. d. e. f. g. Make sure that the gauge glass can be isolated and drained separately from the transmitter. (See Figure 3-5) Close the upper and lower gauge valves. Open the drain valves and drain the gauge. Crack open the upper valve and allow the rush of steam to pass through the gauge, cleaning the glass. Close the upper valve. Inspect the gauge for cleanliness and if necessary repeat 3 and 4. Close the drain valve and slowly open the upper and lower gauge valves. The gauge should now be clean and ready for service.

LEARNING OBJECTIVES • Explain the drum three-element drum level control function using drum level, feedwater flow, and steam flow. Additionally, provide a fundamental list of other process controls typical to this type of three-drum HRSG system. • Describe the monitoring and supervision provided for on the HRSG and supervision provided for on the HRSG and list what parameters will initiate a unit Gas Turbine run back or possible trip. 4.2 CONCEPT for LP, IP, and HP DRUM LEVEL CONTROLS The Feedwater control system modulates the rate of feedwater flow to the boiler to match the steam demand leaving the boiler. A relatively constant drum level is maintained by the control system throughout the operating load range of the boiler. Controlled steam drum level is important for two significant reasons. • An excessively low water flow will expose boiler tubes resulting in overheating of the tube metal. • An excessively high water level will interfere with the steam-water separating equipment in the steam drum. Water separation becomes less effective and some water will be entrained in the steam leaving the drum. Water is then carried over with the steam, resulting in damage to plant equipment. When load demand changes occur, the amount of steam required by the turbine/process changes. The flow of feedwater to the boiler must also change to meet the new load demands. The drum level control system provides for the necessary balance between the turbine and the boiler. An accurate measure of the balance between boiler fluid input and steam flow output is steam drum level. The feedwater control system sustains this balance by maintaining the proper fluid storage level within the boiler at all times. 4.2.1 Drum Level Control HP Drum Level Control (Drum level will be corrected by the drum pressure). Normal Level: The drum level control will regulate the rate of feed water flow to maintain a proper drum level throughout the operation range of the steam generator. To get the maximum benefit from a three-element system, the feed water flow should be proportional to steam flow with reset action on drum level which means that the mass of feed water entering should always be equal to the mass of steam leaving, with continuous corrections made for deviations from level set points.

  • 56. HRSG OPERATION AND MAINTENANCE 4.2.2 Description The feedwater control system is a control loop that, when in automatic maintains a balance of feedwater entering the boiler with the amount of steam leaving the boiler. The control system also keeps the volume of boiler water within the steam drum to an established set point level during operation. The feedwater control system is referred to as a “three-element control system” because three system measurements, or variables, are used to determine the required feedwater rate to the boiler. The three elements monitored are: • Drum level • Feedwater flow • Steam flow The three monitored elements, steam flow, steam drum level and feedwater flow, are measured and converted into electrical signals. The signals are transmitted as feedback control signals, to the control room. The use of three different elements provides a quick response when transients, or changes, occur during unit operation. The Feedwater control system is an analog control system. variable. Feedwater flow is the manipulated variable. 4.2.3 Drum level is the controlled Principles of Operation Drum level is related to, but is not a direct indicator of the quantity of water in the steam drum. Under different and varying steam loads, the steam bubbles occupy a different and varying volume of steam and water mixture. The mixture volume is related to the pressure in the steam drum. Two conditions can affect accurate drum level control. Figure 4-1 depicts these two conditions, called Shrink and Swell. 4.2.4 Shrink In the case of shrink, an increase in pressure in the steam drum due to decreased steam flow results in the water in the steam drum dropping to a temperature lower than saturation. This will cause some of the steam bubbles to condense back into water and others to contract under the increased pressure. The level in the steam drum decreases. The amount of level decrease, or shrink, is dependent on the steam pressure within the steam drum. The greater the rise in steam pressure, the more the level will decrease. The effect shrink produces is a decreasing level even though less mass is actually leaving the steam drum. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 4-5
  • 57. HRSG OPERATION AND MAINTENANCE 4.2.5 Swell If the steam pressure within the drum decreases due to an increase in steam flow, the water temperature within the drum is raised above the saturation temperature for that pressure. This causes some of the water to form additional steam bubbles, and the steam bubbles that are raising in the riser tubes will also expand. To maintain the continued flow of water through the riser tubes, the drum level will increase (swell). The amount of level rise is dependent on the steam pressure within the steam drum. The more the steam pressure decreases the greater the rise in drum level. The result of swell is that the level in the steam drum increases even though additional mass is actually leaving the steam drum. Figure 4-1: Shrink and Swell in a Steam Drum ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 4-6
  • 58. HRSG OPERATION AND MAINTENANCE 4.2.6 Functional Level Control Operation This use of the steam flow and feedwater flow signals minimizes the effects of shrink and swell. The three-element control system provides a smoother control of the drum level. (Figure 4-2). Figure 4-2: Three Element Control With no load changes, steam flow and feedwater flow should be equal to maintain a steady steam drum water level. The steam flow and feedwater flow signals are compared with each other to develop an error signal. This is the flow error (FR) signal. The measured drum level drum level is then compared with the flow error to provide a total error or level-flow error (LE) ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 4-7
  • 59. HRSG OPERATION AND MAINTENANCE signal that is then sent to the level controller (LC). The total error is compared with the setpoint to provide the error signal that positions the feedwater control valve. • In a swell condition (water level is increasing), the water level signal alone will call for less water. However, this would starve the boiler because the swell condition is caused by an increased steam flow (decreased steam pressure), which means more water is needed. By comparing the water level error with the steam flow, the amount of increased water flow called for by the steam and water flow error is balanced against the decrease in flow called for by the rising drum level. This action will continue to occur until steam pressure is restored to normal by stabilizing load demand at a new level. As the water level decreases to normal, more water is allowed to enter the boiler until feedwater flow equals steam flow. • The drum level signal is density compensated to generate a corrected drum level signal to the drum level controller. • To control swell during start-up, drum levels are maintained at a lower control level, just above its low water alarm setpoint, until steam flow reaches 10% of full flow for that system.

  • 66. HRSG OPERATION AND MAINTENANCE SECTION 5: OPERATION 5.1 • • 5.2 LEARNING OBJECTIVES Given a start-up condition (cold, hot) describe the actions and criteria needed to proceed up to full load. Given an abnormal condition, describe the proper procedures to bring the condition back to normal state. HRSG BOILER OPERATIONAL OVERVIEW These procedures are intended to serve as a guide during the initial operating stages of a Heat Recovery Steam Generator (HRSG). They include the proper operating sequences for the steam generator and auxiliary equipment furnished by ALSTOM Power inc. Refer to the Piping and Instrumentation Diagram. The sequential procedures do not include detailed reference to equipment not furnished by ALSTOM Power inc., such as the feed pumps, or the gas turbine, etc. Because the steam generator is only one part of the power plant, and all equipment must operate in unison, specific procedures and detailed values cannot be included in this manual. As operating experience is gained and the controls are fine-tuned, the characteristics and operating requirements of the unit will become apparent. Refer to manufacturer's instructions for further operating details for specific equipment supplied by ALSTOM Power inc. 5.3 COMPLETION OF MAINTENANCE PRIOR TO OPERATION Check the HRSG to make sure that all maintenance work has been completed, all tools and debris have been removed, the handhole plates and manhole covers have been installed and secured, and all access doors have been installed and secured. Check the safety valves to see that the gags have been removed, the lifting levers have been replaced, and the valves are not fouled or hung up. NOTE: Some equipment such as Valves, Instrumentation, Pumps, etc. mentioned in this manual may not be part of Alstom Power Scope of supply, so it may not shown on the Alstom Power’s P&ID drawing or referred documents. 5.4 INITIAL FILLING This section describes the recommended procedure for fiIIing an empty HRSG with water. If the unit is hot, filling of a pressure level system with cold water should not be initiated until the drum metal temperature for that pressure level has cooled to within 56°C (100°F) of the incoming feedwater temperature. Filling should be done slowly, with the feedwater control valve at 10% open, to avoid severe temperature strains. Otherwise, damage may result due to relatively cool water coming into contact with heated pressure parts. Also, since deposits of solids in a superheater can cause corrosion or inhibit heat transfer, introduction of solids by carryover of boiler water from the drum during filling, hydrostatic testing or chemical cleaning must be avoided.

During normal, base load operation of the HRSG, when the GT is using Natural Gas, the Condensate Preheater Recirculation Pump (PMP-040) is switched ON when the condensate feedwater temperature is < 51.7°C (125°F). The pump is switched OFF automatically when the condensate feedwater temperature is > 55°C (131°F). The Condensate Preheater Feedwater Stop Valve (HV-002) is positioned in the fully-opened position and the Condensate Preheater Bypass Stop Valve (HV-003) Is positioned in the fully-closed position. NOTE: A minimum temperature difference of approximately 2.5°C must be maintained between the saturation temperature in the Deaerator based on the operating pressure (PIT-001D and PIT-002D) and the incoming feedwater temperature (TE-066A and TE-066B) in order to ensure proper operation of the Deaerator. CAUTION: The Condensate Preheater Recirculation Pump (PMP-040) must never be run with suction and discharge valves closed. Damage to the pump will occur if there is no water flow through the pump. Ensure that the Minimum Recirculation Stop Valve (V-062) is fully open before starting the pump. 5.7 START-UP FROM A COLD CONDITION This section describes the recommended procedure for starting the HRSG from a cold condition with no pressure in the HP, IP and LP boiler sections. Proceed as follows: 1. Purge the HRSG in accordance with NFPA 85, Chapter 8.9.2 (Combustion Turbine Exhaust Systems) guidelines. It is understood that purging is accomplished by using air at ambient temperatures. The ambient air temperatures during a normal purge cycle will not have any damaging effect on any of the HRSG components. 2. Align all HRSG valves as shown under the column labeled “START FROM COLD” on Tables 1 through 6. NOTE: Some of the following procedures are redundant to what is shown on Tables 1 through 6. This is done to emphasize the importance of performing these procedures. 3. Open the Stack Damper before rolling the Gas Turbine.

NOTE: When starting the second gas turbine/HRSG train, with the first train already operating, the HP Main Steam Outlet Stop Valve (HV001), and the LP Main Steam Outlet Stop Valve (HV-919) shall remain closed until the pressure is within 5% and temperature is within 28°C of downstream piping. After permissives clear and stop valves open, the NRV in the respective lines will open once the pressures match and will then begin admitting steam. 15. If needed, restart feedwater pumps and ensure that pumps are running and all feed system valves are lined up. (See ‘START FROM COLD’ on Tables 1 through 6.) 16. Allow gas turbine exhaust flow to the HRSG by starting the gas turbine. 17. While the steam generator is being brought up to pressure, all cold steam piping should be gradually heated and drained of condensate. The HP Startup Vent Valve (HV-342), RH Steam Outlet Startup Vent Valve (FV-780), IP Startup Vent Valve (HV600), and the LP Startup Vent Valve (FV-915) must stay opened to insure a positive flow of steam which will reduce thermal expansion. To warm the piping downstream of ALSTOM Power scope, open the bypass valve on the HP Main Steam Outlet Stop Valve (HV-001A), the bypass valve on the LP Main Steam Outlet Stop Valve (HV-919A). Next, open a drain or vent downstream of ALSTOM Power scope to allow the steam from the bypass valve to warm the piping. Ensure that all steam piping downstream of the boiler piping is drained prior to admitting steam. NOTE: When starting the second gas turbine/HRSG train with the first train already operational, the bypass valves on the Main Steam Outlet Stop Valves are used to warm piping. 18. Once the LP steam lines have been properly warmed, the LP steam section is “on line” with steam ready to be introduced to the Deaerator. Open the LP Main Steam Stop Valve (HV-919) and close the bypass (HV-919A). The LP Startup Vent Valve (FV-915) will modulate open / closed in order to maintain the LP Steam Outlet Pressure (PIT-915A and PIT-915B) at 4.19 barg (5.20 bara). 19.

  • 74. HRSG OPERATION AND MAINTENANCE For Startup on Natural Gas Operation: 27. Prior to beginning the final temperature step increase of the GT while operating at 50% load, complete the following change-overs: • Disengage the bypass of the Condensate Preheater by turning on the Preheater Recirculation Pump (PMP-040) and opening the Recirculation Pump Discharge Control Valve (TV-040) to 100% open. To prevent thermal shock of the Preheater manifold, keep the Condensate Preheater Bypass Stop Valve (HV-003) open for 15 minutes after opening the Condensate Preheater Feedwater Stop Valve (HV-002). Set Feedwater Heater Recirculation Control in AUTO mode. The amount of recirculation flow should be such that the temperature entering the Condensate Preheater (TE-005A and TE-005B) is at or above the set point of 51.7°C. (Refer to Condensate Preheater Recirculation Operation section.) A minimum temperature differential of approximately 2.5°C must be maintained between the saturation temperature in the Deaerator based on the operating pressure (PIT-001D and PIT-002D) and the incoming feedwater temperature (TE-066A & B) in order to ensure proper operation of the Deaerator. • The Low Range LP Pegging Steam Control Valve (PV-002D) should be in AUTO mode so as to be able to control the pegging steam flow to the Deaerator as the total required pegging steam flow decreases. As the temperature of the feedwater entering the Deaerator increases the total amount of pegging steam required while maintaining the Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) at 0.99 barg (2.00 bara) will decrease. Modulate closed as required the IP Pegging Steam Control Valve (PV-003D) first and then the High Range LP Pegging Steam Control Valve (PV-001D). Prior to completely closing the High Range LP Pegging Steam Control Valve (PV-001D), switch control of the LP pegging steam flow over to the Low Range Pegging Steam Control Valve (PV-002D).

HRSG OPERATION AND MAINTENANCE 5.8 START-UP FROM A WARM CONDITION This section describes the recommended procedure for starting the HRSG from a Warm / Hot condition, which is when the HP Drum Pressure (PIT-260 and PIT-261) > 1.72 barg (2.74 bara). Proceed as follows: 1. Purge the HRSG in accordance with NFPA 85, Chapter 8.9.2 (Combustion Turbine Exhaust Systems) guidelines. It is understood that purging is accomplished by using air at ambient temperatures. The ambient air temperatures during a normal purge cycle will not have any damaging effect on any of the HRSG components. 2. Align all HRSG valves as shown under the column labeled “START FROM WARM” on Tables 1 through 6. NOTE: Some of the following procedures are redundant to what is shown on Tables 1 through 6. This is done to emphasize the importance of performing these procedures. 3. Open the Stack Damper before rolling the Gas Turbine. 4. The HP Desuperheater Spray Water Control Valve (TV-301) is in ‘AUTO’. The HP Desuperheater Spray Water Control Valve Isolation Valves (V-313 and V-317) shall remain open. The HP Desuperheater Spraywater Power Block Valve (HV-300) is in ‘AUTO’. 5. The RH Desuperheater Spray Water Control Valve (TV-701) is in ‘AUTO’. The RH Desuperheater Spray Water Control Valve Isolation Valves (V-713 and V-717) shall remain open. The RH Desuperheater Spraywater Power Block Valve (HV-700) is in ‘AUTO’. NOTE: Although desuperheating is not required except at peak turbine load, it is good practice to have the control station available whenever the unit is operating. 6. The following Drain Valves are in AUTO: HP Superheater 1 Drain Valve (HV-284), HP Superheater 2 Drain Valve (HV-282), HP Superheater 3 Drain Valve (HV-280), Allow any condensate in these sections to drain. 7. The following Drain Valves are in AUTO: Reheater 1 Drain Valve (HV-765), Reheater 2 Drain Valve (HV-760), IP Superheater Drain Valve (HV-580) Allow any condensate in these sections to drain. 8. The LP Steam Outlet Drain Valves (HV-948 and HV-949). Allow any condensate to drain. 9. Prior to start up, reset the water level set points in the feedwater control system to ensure that the water levels in the HP, IP, and LP Drums and the Deaerator Storage ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 5-10

Use the HP Evaporator (HV-180), IP Evaporator (HV-480) and LP Evaporator (HV-825) Intermittent Blow-off Valves as necessary to reduce water levels. 10. Open the HP Feedwater Inlet Stop Valve (HV-102), IP Feedwater Stop Valve (HV400) and LP Feedwater Stop Valve (HV-800). 11. Place the Condensate Preheater in bypass by closing the Condensate Preheater Feedwater Stop Valve (HV-002) and opening the Condensate Preheater Bypass Stop Valve (HV-003). Set the Preheater Recirculation Pump (PMP-040) and Control to OFF. 12. Close the HP Main Steam Outlet Stop Valve (HV-001), open the HP Steam Startup Vent (HV-342). Engage the HP to RH Bypass Valve (not in ALSTOM Power scope) to control the HP Steam Outlet Pressure to 58.99 barg (60.00 bara). 13.

Close the HRH Stop Valve (not in ALSTOM Power scope) and the HRH to Condenser Bypass (not in ALSTOM Power scope). 14. Close the LP Main Steam Outlet Stop Valve (HV-919) and open the LP Steam Startup Vent (FV-915). NOTE: When starting the second gas turbine/HRSG train, with the first train already operating, the HP Main Steam Outlet Stop Valve (HV-001), and the LP Main Steam Outlet Stop Valve (HV-919) shall remain closed until the pressure is within 5% and temperature is within 28°C of downstream piping. After permissives clear and stop valves open, the NRV in the respective lines will open once the pressures match and will then begin admitting steam. 15. If needed, restart feedwater pumps and ensure that pumps are running and all feed system valves are lined up. (See ‘START FROM WARM’ on Tables 1 through 6.) 16. Allow gas turbine exhaust flow to the HRSG by starting the gas turbine. 17. While the steam generator is being brought up to pressure, all cold steam piping should be gradually heated and drained of condensate. The HP Startup Vent Valve (HV-342), RH Steam Outlet Startup Vent Valve (FV-780), IP Startup Vent Valve (HV600), and the LP Startup Vent Valve (FV-915) must stay opened to insure a positive flow of steam which will reduce thermal expansion. To warm the piping downstream of ALSTOM Power scope, open the bypass valve on the HP Main Steam Outlet Stop Valve (HV-001A), and the bypass valve on the LP Main Steam Outlet Stop Valve (HV-919A). Next, open a drain or vent downstream of ALSTOM Power scope to allow the steam from the bypass valve to warm the piping. Ensure that all steam piping downstream of the boiler piping is drained prior to admitting steam. NOTE: When starting the second gas turbine/HRSG train with the first train already operational, the bypass valves on the Main Steam Outlet Stop Valves are used to warm piping. 18. Once the LP steam lines have been properly warmed, the LP steam section is “on line” with steam ready to be introduced to the Deaerator. Open the LP Main Steam Stop Valve (HV-919) and close the bypass (HV-919A) when the system is ready to receive the LP steam.

To prevent thermal shock of the Preheater manifold, keep the Condensate Preheater Bypass Stop Valve (HV-003) open for 15 minutes after opening the Condensate Preheater Feedwater Stop Valve (HV-002). Set Feedwater Heater Recirculation Control in AUTO mode. The amount of recirculation flow should be such that the temperature entering the Condensate Preheater (TE-005A and TE-005B) is at or above the set point of 51.7°C. (Refer to Condensate Preheater Recirculation Operation section). A minimum temperature differential of approximately 2.5°C must be maintained between the saturation temperature in the Deaerator based on the operating pressure (PIT-001D and PIT-002D) and the incoming feedwater temperature (TE-066A & B). This temperature differential is required in order to ensure proper operation of the Deaerator. • The Low Range LP Pegging Steam Control Valve (PV-002D) should be in AUTO mode so as to be able to control the pegging steam flow to the Deaerator as the total required pegging steam flow decreases. As the temperature of the feedwater entering the Deaerator increases the total amount of pegging steam required while maintaining the Deaerator Storage Tank Pressure (PIT-001D and PIT-002D) at 0.99 barg (2.00 bara) will decrease.

When the HP Drum pressure falls below 1.72 barg (2.74 bara), the drum pressure may be allowed to decrease to atmospheric pressure by opening the HP Saturated Steam Outlet Vent Valves (V-280 and V-281) or a nitrogen blanket may be maintained by opening the HP Nitrogen Stop Valve (V-263). 19. When the IP Drum pressure falls below 1.72 barg (2.74 bara), the drum pressure may be allowed to decrease to atmospheric pressure by opening the IP Saturated Steam Outlet Vent Valves (V-580 and V-581) or a nitrogen blanket may be maintained by opening the IP Nitrogen Stop Valve (V-563). 20. When the LP Drum pressure falls below 1.72 barg (2.74 bara), the drum pressure may be allowed to decrease to atmospheric pressure by opening the LP Saturated Steam Outlet Vent Valves (V-906 and V-907) or a nitrogen blanket may be maintained by opening the LP Nitrogen Stop Valve (V-888). 21. When the Deaerator pressure falls below 0.10 barg (1.11 bara), the storage tank pressure may be allowed to decrease to atmospheric pressure by opening the Deaerator FW Heater Vent Valves (V-016D and V-017D) or a nitrogen blanket may be maintained by opening the Deaerator Storage Tank Nitrogen Stop Valve (V063D). NOTE: Vent valves are provided with 13 mm (0.5 inch) orifice drilled into the gate disk. Therefore, blanking plates shall be installed before nitrogen blanketing of the deaerator and storage tank. 5.10 SECURING TO DRAIN (WITHOUT NITROGEN BLANKETING) This section describes the recommended procedure for securing the HRSG without nitrogen blanketing in order to drain the unit prior to performing maintenance.

These main steam vent valves must be opened before the associated drum pressure falls any lower to prevent a vacuum from developing that may cause leakage of the drum manway gaskets. 4. When the Deaerator pressure falls to 0.10 barg (1.11 bara), open the Deaerator FW Heater Vent Valves (V-016D and V-017D). 5. The HRSG can be drained when it is completely cooled (when vapor no longer escapes from the vents). 6. Open the vent valves and drain valves one heat exchanger section at a time to avoid overloading the drain discharge system downstream of the HRSG. Open the Blowdown Stop Valves if the blowdown lines are to be drained. 5.11 CONTROLS AND INSTRUMENTATION Controls It is beyond the scope of this manual to discuss the design parameters and selection criteria of control systems. Instead, we will review the steam generator dynamics involved in tuning these systems and note problems we have found on actual operating units. When we discuss steam generator control, we are actually referring to the drum level controls; all other controls are supplied by others. The drum level controls will regulate the rate of feedwater flow to maintain a proper drum level throughout the operating range of the steam generator. To get maximum benefit from a three-element system, feedwater flow should be proportional to steam flow with reset action on drum level. This means that pounds of feedwater entering should always equal pounds of steam leaving, with periodic small corrections made to correct deviations from level set points. The best drum level control is achieved through mass flow balance. Instrumentation Even the most sophisticated and well-tuned control systems do not take the place of the judgment of an alert, motivated and trained operator. The only means that an operator has to make his judgements is through adequate and calibrated instrumentation.

  • 83. HRSG OPERATION AND MAINTENANCE 5.12 SAFETY VALVES Safety valves serve to protect pressure vessels from overpressure. On superheater outlets they serve the additional purpose of protecting the superheater from overheating in the event of a sudden interruption in steam consumption. The total relieving capacity of the safety valves on a boiler cannot be less than the design steaming capacity. It is a Code requirement that one or more safety valves on the steam drum be set at or below the design pressure of the unit. Any economizer which can be isolated from the boiler must have its own safety valve. The discharge capacity of any superheater safety valve or valves can be included in the total relieving capacity of the boiler, provided there is no way to isolate the superheater. Valves are to be designed to operate without chattering and to obtain full lift at no more than 3% above their set pressure. Valves are to close within 4% of set pressure, but no less than 2% of set pressure. The popping point tolerance shall not exceed: 2 psig for pressures up to 70 psig. 3% for pressures up to 300 psig. 10 psig for pressures up to 1000 psig. 1% for pressures over 1000 psig. ALSTOM Power recommends that all safety valves be lifted to check popping pressure and blowdown prior to annual maintenance outages. During these outages, valves that leaked or had a tendency to simmer or chatter should be disassembled and repaired. During valve testing, it is important to maintain drum level at or below normal water level to prevent water damage to drum valve seats and to prevent high solids boiler water from being drawn into superheaters. Any time a valve is disassembled, its seat should be touched up with a lap and 1000 grit-lapping compound. If the seat is in poor shape, use a carborundum disc first, then progressively finer grits. The following are safety tips and helpful hints: 1. Never set safety valves by holding set pressure and lowering the popping pressure setting with a wrench. This is extremely hazardous. Valve setting changes should be made with the boiler pressure considerably lower than set point. After the wrench adjustment is made the lifting gear should be replaced and boiler pressure should be raised to the new popping point. 2. Ring locking pins can vibrate loose when a valve is relieving. The pins should always be wired to each other except when one pin is removed to make a ring adjustment. 3. Entrained water will cause excessive blowdown on drum valves. Set drum valves with the drum water level a few inches below normal water level, if possible. 4. A rule of thumb: Vent pipes should be 2 inches larger in diameter than the valve discharge pipe. 5. The discharge pipe should extend no more than 14 inches into the vent pipe from the bottom of the drip pan. 6. A safety valve seat can be damaged by debris and water, which enters the valve body through the vent pipe. This debris is blown around when the valve lifts. Covering the vent pipe with a plastic bag can eliminate the problem. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 5-18
  • 84. HRSG OPERATION AND MAINTENANCE 7. It is occasionally necessary to mount a vent pipe rigidly to the discharge elbow. This should be done only when there is no alternative. Care should be taken that the vent pipe is cut off square, not on the bias. 8. Do not exceed five pops on a valve. If more pops are required, allow valve to cool before proceeding. 9. Do not make adjustments on first pop. Always evaluate the necessary adjustment from two pops. 10. When popping a valve, always have the cap and drop lever assembly in place with a rope affixed. If the valve begins to chatter, it can be manually popped before the seating surfaces are damaged. 11. Observe the popping pressure on a suitable gauge mounted in the proximity of the valve being tested. A second gauge, preferably a dead weight gauge, should be used to validate the calibration of the observed gauge. 5.13 FW PREHEATER BYPASS OPERATION When operating the HRSG Unit with Distillate Oil, the FW Preheater should be bypassed. To bypass the FW Preheater, ensure you isolate the LP Feedwater Stop After Bypass Valve (YVD06). Ensure the FW Preheater Bypass Isolation Valves (ISV-D720A and ISV-D720B) are open and set the FW Preheater Bypass Modulating Valve in manual (or auto). 5.14 EMERGENCY PROCEDURES High Water Level Abnormally high water levels should be avoided, as it may lead to carry-over and even priming. In the event of a high water level, there will be a high drum level alarm. Proceed as follows: 1. Isolate the feedwater supply for the appropriate drum using the HP Feedwater Control Valve (LV-100) and HP Feedwater Stop Valve (HV-102), IP Feedwater Control Valve (LV-430) and IP Feedwater Stop Valve (HV-400), LP Feedwater Control Valve (LV-801) and LP Feedwater Stop Valve (HV-800) and Condensate Preheater Outlet Control Valve (LV-064), Condensate Preheater Feedwater Stop Valve (HV-002) and Condensate Preheater Bypass Stop Valve (HV-003) as required. 2. Close the Bypass Stack Diverter Damper to HRSG using Normal Closing Speed (60 seconds). Damper may be reopened once the alarm clears, the cause of the alarm has been corrected and the GT is operating at or below 20% load. See Simple to Combined Cycle Operation for details. 3. Blowdown the appropriate drum until the water level is at the normal level. Use the HP Intermittent Blow-off Valve (HV-180), IP Intermittent Blow-off Valve (HV-480) and LP Intermittent Blow-Off Valve (HV-825) as required. The Intermittent Blow-off Valves may be used when the HRSG is operating at any pressure in order to reduce the drum water level.

Isolate the steam outlet for the appropriate drum using the HP Main Steam Outlet Stop Valve (HV-001), IP Main Steam Outlet Stop (HV-HV-604) and the LP Main Steam Outlet Stop Valve (HV-919) as required. Open Superheater Drain Valves for appropriate drum using HP Superheater Drains (HV-284, HV-282 and HV-280), IP Superheater Drain (HV-580) and LP Superheater Drain (HV-948) as appropriate. 5. If the alarm has not cleared within 2 minutes and the Bypass Stack Diverter Damper is not completely closed to HRSG, initiate trip of gas turbine. 6. Investigate the water conditions (alkalinity and solids). Low Water Level If the water level falls out of sight in the water gauge, due to failure of the feedwater supply or neglect of the operator, appropriate action should be taken at once. The only exception is in the case of momentary fluctuations that might occur with extraordinary changes in load. Any decision to continue to operate, even if only for a short time at a reduced rating, would have to be made by someone in authority who is thoroughly familiar with the circumstances that led to the emergency and positively certain that the water level can be restored immediately without damaging the boiler. In the absence of such a decision: 1. Close the Bypass Stack Diverter Damper to HRSG using Normal Closing Speed (60 seconds). If the alarm does not clear within 2 minutes, initiate trip of the gas turbine. If the alarm is cleared within 2 minutes and if the cause of the alarm is identified and corrected, the Bypass Stack Diverter Damper may be reopened once the GT is at or below 20% load. See Simple to Combined Cycle Operation for details. 2. Isolate the steam outlet for the appropriate drum using the HP Main Steam Outlet Stop Valve (HV-001), IP Main Steam Outlet Stop (HV-604) and the LP Main Steam Outlet Stop Valve (HV-919) as required. 3. If the condition has not been stabilized and gas turbine trip has been initiated, allow HRSG to cool so that it may be inspected for damage if required. After correcting the cause, the unit may be restarted. CAUTION: Do not attempt to add water until the steam generator has cooled down sufficiently to where the drum metal temperatures are within 56°C (100°F) of the feedwater temperature; otherwise, damage may result due to relatively cool water coming in contact with heated pressure parts. Tube Failure 1. Immediately secure the gas turbine exhaust flow. 2. Secure unaffected sections of HRSG according to “Securing to Warm Lay-up Condition” instructions. 3. Isolate and drain affected sections of HRSG according to “Securing to Drain” instructions. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 5-20
  • 86. HRSG OPERATION AND MAINTENANCE Loss of Feedwater Supply The loss of feedwater supply is a rare occurrence in a properly maintained steam plant. However, loss of the feedwater supply can happen and it is to be treated as an extreme emergency. A steady persistent drop in the steam drum level indicates problems with the feed pump, feed pump recirculation control, steam generator feedwater valve control or a tube leak. By quickly comparing system pressures and flows with data taken at comparable loads during normal operation, the operators should be able to identify the problem area. If feedwater flow is increasing relative to steam flow and the drum water level is still falling, a tube leak can be assumed. Secure the gas turbine exhaust flow and proceed with tube failure emergency procedures (see Emergency Procedures – Tube Failure section for details). For the HP Drum, an alarm will sound when the drum water goes to the low level. At the low low HP Drum level the gas turbine exhaust flow should be secured. If the problem is with the feed pump or controls, restrict steam generator steam flow to balance the ability of the crippled feedwater system to maintain drum level. If it is not possible to stabilize drum levels by reducing load, secure the gas turbine exhaust flow and bottle up the steam generator, keeping all vents closed. When the feedwater system is repaired, restart the unit as detailed under the procedure titled “Start-Up From A Warm Condition”. In any case, the first consideration must be the protection of the steam generator pressure parts from operation with low water. As is true of any emergency situation with a steam plant, events do not always follow an orderly pattern. The procedures above may or may not fit the pattern for every circumstance. The intent is to emphasize what should be done in order to protect the steam generator and bring the plant back in operation as soon as possible.

  • 100. HRSG OPERATION AND MAINTENANCE 1. INTRODUCTION The main objectives of water chemistry control are to insure the long term integrity of the materials of construction and the successful operation of the boiler-turbine power cycle. The particular types of chemical treatment may very depending on many factors such as the variety of materials, operating conditions, system design, etc. The treatment of the feedwater and boiler water is beyond the control of this company. This company does not assume the responsibility for water treatment and control. This is in accordance with practices established by the American Boiler and Affiliated Industries Standards Committee. The company does however, provide water chemistry guidelines that reflect good industry practices. These guidelines are generally in accordance with published guidelines from EPRI, VGB, ASME, as well as ABMA (American Boiler Manufacturers Association). One notable exception is that the feedwater and boilerwater qualities reflect the steam purity requirements specified by the steam turbine and gas turbine (if steam or water injected) supplier as opposed to those provided in the ABMA guidelines. Feedwater chemistry control is based on the following general considerations: a. Ammonia is used to control pH. b. An oxygen scavenger is not needed if the oxygen concentration is below 10 ppb. If the use of an oxygen scavenger becomes necessary, hydrazine is preferable if allowed by local safety regulations. c. To minimize the risk of flow assisted corrosion in the lowpressure systems (see Appendix II), the pH range has a relatively high limit and the use of organic treatment chemicals is not recommended. Boiler water chemistry control is based on the following considerations: a. General and specific corrosion protection of the pressure parts surfaces in the event of contamination ingress. b. Achieving the required steam purity. There are several accepted methods for controlling boiler water chemistry. The majority of drum type boilers, however, still use some form of phosphate treatment (see appendix I). The particular phosphate treatment (phosphate concentration and corresponding pH) should be selected based on the following main cycle considerations: ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 6-3

General Remarks All conductivity’s and pH are referred to 77°F (25°C). Possible contributions from carbon dioxide may be excluded. Operation is desirable at the lowest achievable impurity levels, with the shortest and least frequent excursions. The specification is related to the following conditions: • Make-up water demand is < 1 % under normal conditions, up to 5 % maximum and intermittent. • Feedwater pH conditioning shall be done with ammonia. Oxygen scavengers such as hydrazine are not required (if copper alloys present in the condensate system, the use of hydrazine can be evaluated). • Organic based treatment chemicals are not recommended and should not be required in a combined cycle power plant generating electricity in which there is no process steam exported from the cycle. Note: This is a general specification valid for the plant type mentioned only. The criteria should be reviewed for a specific application and at commissioning. N Normal value. Values are consistent with long-term system reliability. A safety margin has been provided to avoid concentration of contaminants at surfaces.

  • 104. HRSG OPERATION AND MAINTENANCE APPENDIX I A. Feedwater Quality and Steam Purity. Dissolved Solids and Oxides. The guidelines address the influence of both dissolved and suspended (i.e. oxides) solids. Since the feedwater is used for desuperheating (steam temperature control), its level of dissolved solids must be limited in order to prevent fouling of steam touched surfaces as well as achieve steam purity requirements. It should also be recognized that metallic oxides transported to the boiler (or superheater / reheater/turbine) by feedwater can foul these surfaces such that damage and/or efficiency losses may occur. Oxygen. It is indicated in the feedwater guidelines that the oxygen concentration should be limited to 10 ppb. At the same time, the use of oxygen scavengers such as hydrazine or hydrazine substitutes have been omitted. This is based on the experience from plants on Oxygenated Treatment (OT) where less reducing conditions in low cation conductivity waters (less than 0.2 µS/cm) help to form a more adherent / less soluble oxide film. This further minimizes the potential for flow assisted corrosion (FAC) as discussed in a later section. Cation Conductivity. Cation conductivity values do not include the influence of carbon dioxide. During normal operating conditions, levels of 0.06-0.2 µS/cm can be achieved. Higher values are observed during startup. Carbon dioxide, having entered the system with air during shutdown, is dissolved in the water. It requires some time until it is purged from the system. The removal rate depends on the efficiency of the deaeration devices (deaerator, condenser), as well as on cycle water pH. At cold start, normal specification values are usually obtained within a few hours for base loaded plants. Cyclic units with frequent cold starts require a significant proportion of the operating time to reach normal values. Therefore, the question is whether it is worthwhile to extend heat-up and bypass operation to achieve a low cation conductivity when solely influenced by carbon dioxide. We have investigated startup cation conductivity in several plants with an ion-chromatograph. One example is given in Figure 1. It is seen that cation conductivity started well above 1µS/cm, but with exclusion of carbon dioxide, it was never larger than 0.3 µS/cm when the turbine was on line. Such analytical techniques are normally not available in a power plant. Even if the plant would have such equipment installed, it is doubtful if it could be brought to full operating conditions by the beginning of a cold start. The same applies to degassed cation conductivity measurements. We therefore looked at substitute parameters for evaluating steam chemistry. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 6-7
  • 105. HRSG OPERATION AND MAINTENANCE The boiler water is a good indicator for the ingress of any impurities, and its relation to steam chemistry is fairly well understood. We have therefore formulated our requirement for steam cation conductivity at startup as follows: "The steam turbine can be kept in operation with boiler water purity within the specification and the conductivity of HP steam showing a large decrease in conductivity within one hour from the beginning of turbine operation." B. Boilerwater Quality The boilerwater quality and respective treatment is designed to produce steam with a sodium content not to exceed 10 ppb. Therefore, a low level sodium phosphate treatment has been selected. Figure 2 is a plot of phosphate vs. pH. This type of strong alkaline treatment provides good buffering capabilities in the event of impurity ingress. In those plants where phosphate treatment can be used in the LP boilers, it will also prevent the risk of Flow Accelerated Corrosion (FAC). The listed phosphate range is 2 to 6 ppm. This is limited by the sodium steam purity requirements and the steam drum mechanical or moisture carryover performance. It should be realized that the American Boiler Manufacturers Association (ABMA) guidelines allow a higher dissolved solids level (or sodium level) in the boilerwater. Consequently, for these high operating pressure ranges, the resulting sodium level in the steam will be higher than that allowed by turbine suppliers. Therefore, the turbine steam purity requirements as specified by the turbine suppliers’ control the level of phosphates and other dissolved solids in the boilerwater. All Volatile Treatment (AVT) and Equilibrium Phosphate Treatment (EPT) can be applied in specific cases should phosphate hideout occur. Each boiler is normally controlled and treated independently although the guidelines list the same level of treatment chemicals and conductivity. With demineralized feedwater, there really is no need to allow higher dissolved solids in lower pressure boilers just because it can handle it without adversely affecting steam purity. The use of Sodium Hydroxide is considered to be risky for lowstaffed power plants, as it requires much more attention and control to be safely applied. In a typical combined cycle, the condensate or feedwater is relatively free of iron oxide during stable operation. Therefore, there is no need to use organic dispersants in the boilerwater. These organic substances can decompose to carbon dioxide as well as produce organic acids. These acids can then circulate throughout the cycle. As a consequence, they could destabilize (if only treated with ammonia) the magnetite layer on the LP boiler ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 6-8

  • 108. HRSG OPERATION AND MAINTENANCE APPENDIX II A. Flow Accelerated Corrosion (FAC) Major parameters, which influence FAC, are: pH, turbulence (flow geometry and velocity), steam moisture in two-phase flow, temperature, oxygen concentration, and material composition. In the steam/water system, FAC is mainly observed in the temperature range between 175-450°F (80-230°C), with a maximum in the temperature range around 300-350°F (150180°C). Regions of concern are: • • • • Economizer tubes at HP and IP inlet headers LP-evaporator surfaces at bends LP-drum internals LP horizontal evaporative tube bends To date, economizer, low pressure evaporative tubes (at bends), and drum internals have experienced FAC in several heat recovery steam generators in combined and co-generation cycle plants. Economizer inlet tubes have experienced FAC due to low pH conditions (in 3 plants, steam purity requirements did not allow the use of feedwater pH control chemicals, thus the pH was in the range of 6.5 to 7). Evaporative tubes and other LP components such as drum internals with few exceptions have normally not experienced this type of attack with either AVT treatment (pH in the range of 9.2 –9.6) and certainly not with strong alkaline chemical additives (such as phosphates). The exceptions (3 cases) involved FAC of drum internals in LP boilers where an organic water chemistry program (organic dispersants, organic amines, and organic oxygen scavengers) was used. In summary, a fluid environment needs to be provided that can promote oxide stability and at the same time meet plant requirements. In other words, high feedwater pH controlled with ammonia and no oxygen scavengers is recommended as long as the normal oxygen content is less than 10 ppb (the need to use organic amines for feedwater and condensate pH control in co-generation facilities should be evaluated for each specific site). Flow assisted corrosion of carbon steel is defined as the acceleration or increase in the rate of corrosion caused by the relative movement between a corrosive fluid (either single phasewater or two phases-water and steam mixture) and the metal surface. The main influence of fluid velocity and/or turbulence is the localized removal of protective surface films (magnetite) which then leads to accelerated corrosion of the base metal. The dissolution of the magnetite film is enhanced by the mass transport of soluble iron species (Fe II) away from the surface. If the rate of mass transfer of these species to the bulk of the fluid is ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 6-11
  • 109. HRSG OPERATION AND MAINTENANCE accelerated by flow/turbulence, it will increase metal loss as iron oxidizes to replace the dissolved film. The 1988 American Power Conference paper by Henzel, et al "Erosion Corrosion in Power Plants under Single - and Two Phase Flow Conditions - Updated Experience and Proven Counteractions" provides a useful summary of some of the research on FAC. Major parameters which influence erosion corrosion or FAC are 1) velocity, 2) temperature, 3) pH, and 4)oxygen concentration. Velocity: The effect of velocity or turbulence is to increase the mass transfer of chemical species to and away from the metal surface. This is not a case of "mechanical" abrasion or erosion. Normally, the erosion corrosion studies cover high velocity ranges compared to what we might expect for mean velocity in boiler tubes or feed pipes, however, as we know from field experiences, even at "normal velocity", erosion corrosion can occur depending on the severity of the fluid properties. Under these conditions, FAC problems typically occur in turbulent areas (tubes in inlet headers, bends, tees, valves, etc.) where the local velocity vectors may be much higher than the mean. Temperature: The effect of temperature on metal loss parallels the effect of temperature on solubility of iron oxide (magnetite) in water. At low temperatures, the oxide that is formed is iron hydroxide; this shifts to magnetite at high temperatures. These two materials have different solubility characteristics, accounting for a temperature peak around 300 - 350 F (150-177C). Minimum and maximum temperature limits have been reported for the most part in the range of 170F (77C) and 450F (232C), respectively. Oxygen: Oxygen would normally be thought to cause additional corrosion and in the presence of dissolved solids, it does increase corrosion. In an environment of high purity water, oxygen acts to stabilize the protective coating and actually reduces the rate of metal loss. This is the same principle being exploited for Oxygenated Treatment in once-through units. pH: The pH and the oxidation–reduction potential (ORP) of the fluid in a typical system are the more influential of these parameters since it directly affects the solubility of iron oxide/hydroxide. Either of these conditions such as low pH or a high negative ORP (reducing conditions) can cause this corrosion. Maintaining the pH as high as practical will minimize the dissolution of iron oxide. When the pH is reduced below 8.5, the potential for FAC is increased substantially. The maximum metal loss occurs from pH 7 and below into the acidic range. Although ORP is not usually a standard measurement, chemistry conditions that promote a reduced environment must be avoided. This topic is discussed in greater detail in a following section on iron oxide solubility. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 6-12
  • 110. HRSG OPERATION AND MAINTENANCE Iron Oxide Solubility Iron oxide or magnetite dissolution is typically represented by the Sweeton and Baes equilibrium reaction: 1/3Fe3O4 + (2-b)H+ + 1/3H2 = Fe(OH)b (2-b)+ + (4/3-b)H2O Ferrous hydroxide on the right side of the equation is the soluble product. As indicated by this equation, the dissolution of magnetite is influenced by the oxidation-reduction potential (ORP) of the solution as represented by hydrogen (H2). It is also influenced by the pH as represented by the hydrogen ion. Therefore, the dissolution increases as the ORP becomes more reducing (negative potential) and the pH decreases. The reaction is also a diffusion-gradient driven process, which involves the mass transfer of the ferrous ions from the oxide layer to the bulk fluid. Therefore, the dissolution rate is dependent on the local flow conditions. Turbulent flow increases the dissolution rate. Areas of turbulence in HRSG components which have been known to experience FAC are tube bends/elbows, inlet header tubes (simulates a “T” connection) and steam drum perforated/centrifugal separators. Other chemical substances such as organic compounds can affect the solubility of iron oxide. For example, organic contaminants can thermally degrade at higher temperatures to form compounds such as acetates or acetic acid. These can affect the solubility of magnetite and at the same time form a soluble iron acetate compound. Ammonia, which is used for feedwater pH control, has a lower dissociation rate at higher temperatures so that the local high temperature pH can be substantially lower than measured at ambient temperature. This is normal behavior and taken into account in cycle water chemistry. However, organic substances could enter the cycle, become acidic at higher temperatures and significantly affect the pH even with ammonia present. Ammonia also volatilizes at higher temperatures. This will also have a lowering effect on pH. Unlike ammonia, strong alkaline substances such as trisodium phosphate used in the boilerwater provide a high pH unaffected by temperature and can form stable/non-volatile compounds. The potential for FAC in boiler or evaporator tubes is negligible if the boilerwater is properly treated with phosphate chemistry.

  • 112. HRSG OPERATION AND MAINTENANCE SECTION 7: INSPECTION and MAINTENANCE 7.1 LEARNING OBJECTIVES Identify areas to inspect, possible inspection findings, and approaches for repair to major pressure parts. 7.2 HRSG INSPECTION RECOMMENDATIONS HRSG General Inspections should be carried out approximately once every twelve months. These inspections should be coordinated with the scheduled plant outages of other major combined cycle plant equipment and inspection requirements of the Authorized Inspector. In addition, detailed Inspections should be carried out every 5 - 10 years depending on plant operating history. This detailed inspection is primarily a visual inspection of all accessible pressure parts. The visual inspection will identify any areas of concern that require subsequent Non-Destructive Examination (NDE). Descriptions of the General Inspections and Detailed Pressure Part Inspections follow. General Inspection (Annual) Inlet Duct and Boiler Casing The following items are noted during the inspection. • • • • • • External Casing is inspected externally to identify any areas of significant overheating or cracking. Internal Liners are inspected for severe warpage, excessive loss of stud/washer attachments, liner cracking and loss of insulation. Gas Baffles are inspected for mechanical integrity. Flow Straighteners are inspected for overall mechanical and weld integrity. Duct Burners are inspected for mechanical/weld integrity, burner component overheating, fouling and wear. Detailed inspection of burner elements, ignitors and scanners should be made pursuant to manufacturer’s recommendations. Expansion Joints are inspected internally and externally. Pressure Parts All readily accessible pressure part components are visually inspected. Tubing within the gas path is inspected for severe or progressive bowing, fin/tube weld integrity and evidence of fouling, deposits or corrosion. Particular attention to the cold end sections is recommended. Internal inspection of the drums and deaerator should be carried out. All headers and connecting piping within the upper and lower vestibules should be visually inspected. All external piping and valves should be inspected noting hanger condition and valve condition. All pressure part casing penetrations should be inspected for evidence of cracking. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 7-1
  • 113. HRSG OPERATION AND MAINTENANCE Stack External and internal inspection of the stack should note mechanical integrity and evidence of internal corrosion. Stack Dampers should be inspected to verify full open and full closed capability and evidence of vibration and wear. Stack silencers should be inspected for mechanical integrity, warpage and integrity of fiber packing. SCR and CO Catalyst (If Applicable) SCR and CO Catalyst should be inspected for mechanical integrity of supports, erosion/corrosion of the catalyst elements and evidence of fouling or deposits within the catalyst elements. Ammonia injection grids should be inspected for integrity of the mechanical supports and condition of the injection nozzles. The ammonia supply system should be inspected pursuant to the manufacturer recommendations. Detailed Inspection (Every 5 - 10 Years) Visual Inspection This inspection usually includes the following: • Steam Drums and Steam/Water Separator • Upper and lower evaporator headers adjacent to access areas • Upper and lower economizer headers adjacent to access areas • Upper and lower superheater and reheater headers adjacent to access areas • Downcomers, risers, connecting lines • Superheat and reheat piping • Feedwater piping • Boiler water circulating pumps • RH and SH desuperheaters • Deaerator • Orifices • Strainers This visual inspection is a more detailed inspection that that required annually. This may require removal of insulation and lagging in order to access drum and external piping. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 7-2
  • 114. HRSG OPERATION AND MAINTENANCE The following is noted during the inspection: • The external surfaces, internal surfaces and associated equipment of all drums or steam/water separator should be visually examined for indications of cracks, erosion, corrosion, loose or broken hangers/supports, loose or missing internals that might be indicative of a variety of failure mechanisms and their condition documented. • Condition of full penetration welds and their heat affected zones, (including longitudinal seams for those headers fabricated from plate, girth welds, welds at tees or formed openings and end closures). • Condition of selected socket welds and their heat affected zones (including connecting pipes, vent and drain piping). • Selected bore-holes. • Machined corners of manway seating surfaces. • The steam drum liner or baffling should be visually examined, preferably by means of wet test, for indications of cracks. • The circulating pumps, suction and discharge valves should be checked for fatigue cracking. One of the pumps and one of the suction valves should be internally inspected. • The external surfaces of a header are visually examined for indications of cracks, corrosion, erosion, swelling, exfoliation, discoloration, bowing, loose or broken hangers/supports that might be indicative of a variety of failure mechanisms and their condition documented. • The internal surfaces of a header and bore-holes of terminal tubes may be examined visually for indications of cracks and for abnormalities such as excessive deposits or corrosion. • Desuperheater liners should be inspected for erosion and cracking utilizing a standard boroscope. Nondestructive Examination (NDE) Following Visual Inspection additional NDE tests should be carried out in any areas of concern. The following techniques may be used. • Radiograph • Weld Seam Etching • Diameter and Circumference Measurements • Borehole Examination ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 7-3
  • 115. HRSG OPERATION AND MAINTENANCE One examination routinely performed during a header condition assessment is the examination of header bore-holes. This examination detects the presence of borehole cracking through the use of an oxide cleaning method, fluorescent dye-penetrant examination and visual/dimensional inspection. • Magnetic Particle Examination Magnetic particle examination or testing (MT) and/or wet fluorescent magnetic particle examination (WFMT) should be used at selective locations to determine the existence of mIcrocracks that may not be apparent. Surface discontinuities and shallow subsurface discontinuities can be detected by using this method. Check circumferential seams and a number of socket welds and their heat affected zones (including supply tubes, terminal tubes, vent and drain nozzles). • Liquid-Penetrant Examination Liquid-penetrant examination or testing (PT) is a highly sensitive non-destructive method for detecting discontinuities (flaws) such as cracks, pores and porosity which are open to the surface of solid and essentially nonporous materials. The fluorescent-penetrant inspection (FPT) uses penetrants that fluoresce brilliantly under ultraviolet light. The sensitivity of the fluorescent penetrant (solvent removable) technique is considered to be very high and recommended for areas where minute defects may be present. • Ultrasonic Shearwave Examination Ultrasonic examination, utilizing O° longitudinal sound waves and 45° and 60° refracted shear waves, is extremely useful in detecting the presence of surface and internal discontinuities or non-homogenous areas in materials. This technique provides useful information on whether or not the crack(s) can or should be weld repaired. • Ultrasonic Thickness Measurements Wall thickness readings shall be taken at the dimensional test locations, on selected elbows and bends, and where recordable indications are found. Readings should be taken around the whole circumference of the pipe (0°, 90°, 1800 and 270°) and on the outer wall in the arc of the bend on selected elbows and bends.

  • 116. HRSG OPERATION AND MAINTENANCE 7.3 TUBE CIRCUITS The purpose of the internal inspection is to take a close look at the inside components and areas which are not accessible when the unit is in service in order to find potential problem areas and to repair these areas at a convenient time. Refer to Pressure Part General Arrangement Drawings behind Tab 10. • The inspection begins only after the unit is down, has been cooled, cleaned, and secured. • Make all safety checks and obtain all necessary clearances before opening any of the access doors. • Enter the HRSG through access doors. • A safer and more efficient way of inspecting the interior is with the use of scaffolding, a method that will save time and money in the long run. With an arrangement of scaffolding, a more complete and thorough inspection can be performed, maintenance and repair personnel have easy access to the unit, and continuous access is provided to the entire HRSG. • During the internal inspection, check historic problem areas based on OEM Service Engineering reports. • Use visual observations, comparisons, measurements, and non-destructive examination techniques as methods for the inspection. Recommended Inspection General Areas The tube circuits are arranged in both horizontal and vertical assemblies with the water/steam flow countercurrent to gas flow. • Inspect each of the tube banks for alignment and possible signs of overheating using an outside micrometer. • Check clearance between tube assemblies and casing sidewalls. • Examine all supports. • Examine all baffles and partition plates. • Examine all header assemblies. Inspect welds around tube nipples and headers for cracks and erosion. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 7-5

  • 119. HRSG OPERATION AND MAINTENANCE As previously stated, the steam drum serves several functions: • Provides a point for separating the steam and water • Houses the equipment used for purifying the steam after separation • Houses the header used to distribute the incoming feedwater. Examine the steam/water separating equipment. Inspect the separators, both the primary and secondary stages. Look for corrosion, deposits, erosion, missing parts, etc. Examine the condition of the corrugated plate dryers and the return piping. Drum Inspection Reminders: • Check the condition of the seal around the manway door. • Check the area around the inside of the manway door. • Check the interior of the drum for corrosion and deposits. • Check the condition and mounting of the blowdown pipe and the feedwater distribution header. • Check the downcomer nozzles, screens, and vortex eliminators. • Check all drum internals for wear and fit. • Pay particular attention to the areas behind the primary and secondary separators. • Thoroughly examine the drum internals for cracks. Missing fasteners or separation of the plates will allow boiler water to bypass the steam separation equipment and allow the carryover of boiler water into the superheater. Headers Headers are located throughout the water and steam circuits of the boiler. They collect water or steam from a group of tubes and are not physically accessible for entrance. However, they may have handhole inspection ports which allow for a visual internal inspection. During an inspection, thoroughly inspect the headers inside and out. Header Internal Inspection To perform an internal inspection, remove the handhole inspection ports on the header. Examine the interior for corrosion, deposits, or any other foreign material. Check the area around the handhole for any signs of cracking. Check the handhole seal. ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 7-8

Inspect the area around each header for signs of potential problems. 7.5 DESUPERHEATERS To assist in controlling the final temperature of the steam going to the turbine, a superheater desuperheater is located at the superheater outlet. (Figure 7-3) A desuperheater is also located in the reheat outlet line to provide final reheat steam temperature control during transient conditions. A spray type desuperheater employs spraywater as a cooling medium to the superheated steam. Water is sprayed directly into the steam flow thus adjusting the steam temperature.

HRSG OPERATION AND MAINTENANCE FROM SPRAY WATER SOURCE (BOILER FEED PUMP) Figure 7-3: Desuperheater Schematic A replaceable liner is installed for protection against erosion and thermal shocking of the desuperheater heavy wall-connecting link by the cooler spraywater. Spraywater desuperheaters must utilize feedwater quality water because of the location of the desuperheater in the steam circuitry. By design, there is sufficient time for evaporation of the spray water over the control range of the unit before the steam reaches the turbine for either the superheater or the reheater.

  • 122. HRSG OPERATION AND MAINTENANCE Monitor condition of spray water control and block valves to insure valves maintain tight seals when spray is not required. Inspection The purpose of the desuperheater is to control steam temperature through the use of cool tempering water. Desuperheaters are installed in both the superheater and reheater circuits. The typical in-line desuperheater, shown in Figure 7-4, consists of a shell, liner, and spray nozzle assembly. The shell acts as housing. The spray nozzle assembly introduces the tempering water. The liner protects the shell from thermal shock when the relatively cold tempering water is injected into the steam system.

  • 123. HRSG OPERATION AND MAINTENANCE Figure 7-4: Typical Desuperheater Details Superheater and desuperheater liner inspections should be conducted every three to five years. This inspection is accomplished with a boroscope. The boroscope is inserted through the spray water nozzle opening after removing the spray water control valve or via a hand hole plate. Examine the liner for any gross deformations. Examine the spray nozzles for any enlargement of the nozzle holes. If extensive wastage is found, replace the spray nozzle. 7.6 TUBE FAILURE ANALYSIS (Short Term Overheating) For a specific tube material, there is a maximum allowable stress at a particular temperature. If the tube metal temperature increases beyond this point, creep will occur and the tube will eventually fail by stress rupture. Superheaters and reheaters can experience interruptions and/or reductions in steam flow that can increase tube metal temperatures that lead to stress rupture failures. With ferritic steel, a "fish mouth" or longitudinal rupture, with a thin edge fracture is most likely. With other tube materials, still other appearances are possible. The causes for this type of failure are the following: • Abnormal coolant flow from a blockage in the tube • Blockage due to debris in the tube • Blockage due to scale in the tube • Blockage due to condensate in the tube following an incomplete boilout • Excessive combustion gas temperatures • High temperatures from over-firing during start-up ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 7-12

  • 125. HRSG OPERATION AND MAINTENANCE High Temperature Creep A small fracture may be associated with a blister, while a large fracture could have a thick edged, “fish mouth”, longitudinal crack. The area around the fracture may have an alligator hide appearance, with significant oxide scale penetration. The root causes for high temperature, longer term failure such as these are the following: • High heat flux into a section of the boiler that could have used a higher grade of steel • Excessive hot gas flow through an area that is plugged • Excessive heat absorption from an adjacent lug, or other welded attachment • Partial pluggage from blockage or internal scale Figure 7-6: High Temperature Creep ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 7-14
  • 126. HRSG OPERATION AND MAINTENANCE Dissimilar Metal Welds The weld failures will normally have one side of the weld that responds to a magnet, while the other does not. The weld crack will be circumferential at the weld; over on the side that responds to the magnet; the ferritic side. The cause of failure relate the stress of the two metals expanding differently plus: • Stress from internal steam pressure • Stress from the vertical weight on the weld • Stress from the constraints of how the tube is supported or attached • Internal thermal gradients, which add up to the total stress. The higher the value, the sooner the weld fails. Figure 7-7: Dissimilar Metal Welds ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 7-15
  • 127. HRSG OPERATION AND MAINTENANCE Appearance Welding Defects If the defect is most notable on the inside, it can become a failure from an internal scale buildup, and resultant corrosion, or corrosion fatigue failure. If the defect is with the integrity of the weld itself, the failures often appear as a brittle failure, where stress is concentrated in a small area. Causes again relate to quality control: • The procedure. • Weld material used. • Preparation of the tube ends before the first pass. Pitting - Localized Corrosion (Water-Side Corrosion) Water containing dissolved oxygen is highly corrosive to many metals; therefore everything must be done to minimize the introduction of oxygenated water into the boiler and pre-boiler systems. Oxygen corrosion can dramatically affect various components in operating and nonoperating boilers. Much of the suspended crud that enters an operating boiler is the direct result of oxygen attack of components in the pre-boiler system. Localized pitting is found where oxygen is allowed to come in contact with the inside of the tubes, which is just about anywhere. It appears as a steep edged crater with red iron oxide surrounding the pit. The tube surface near the pit may show little or no attack. Sometimes there is a series of smaller pits. The typical cause starts with: • High levels of oxygen in the feedwater, i.e., poor deaeration at start-up • Filling of condensate in low point, such as bends, when the steam cools • Outages where air gets inside the assembly from adjacent repairs, or vents being left open as the steam condenses ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 7-16
  • 128. HRSG OPERATION AND MAINTENANCE Figure 7-8: Localized Pitting Appearance Stress Corrosion Cracking (Water-Side Corrosion) These thick-edged fractures can be either circumferential or longitudinal, depending on how the stress is oriented. Typically the chemical attack is on the inside of the tube and works its way out through the growing crack. Far less commonly, the chemical attack exists on the outside (gas side) and works its way inward. The root cause is the coupling of more than one factor working on the same location: From the chemistry side are the contaminants of chlorides, sulfates, or hydroxides on either the inside (common) or outside (less common) • • • • • • Contaminants can come from boiler steam drum carry over Contaminants can come from contamination in the desuperheater spray External contaminants come from acidic components to the fuel Additionally there must be a stress possibly from a bend in the tube Weld attachments from initial assembly Or possibly from cyclic unit operation ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 7-17
  • 129. HRSG OPERATION AND MAINTENANCE Figure 7-9: Stress Corrosion Appearance Low Temperature Corrosion (Gas Side) External surfaces of economizer tubes that are exposed to a moist environment containing flue gases can experience acid corrosion. Certain acidic salts (ferrous sulfate for example) can hydrolyze in moist environments to produce low pH conditions that will attack carbon steel. Sulfur trioxide (SO3), present in the cooler flue gas areas, and can react with water vapor to produce sulfuric acid. If the temperature is below the dew point, sulfuric acid condenses along metal surfaces and corrodes the metal. Water washing can also produce acid attack. A gouged exterior and a thin ductile failure characterize this form of failure. When the pressure becomes too great, the pressure inside blows out a hole. The root cause for low temperature failures are: • The presence of sulfur in the oil, which has an opportunity to condense on the last rows of economizer tubes. • The condensing of sulfur and ash when the exit gas temperature is low.

  • 131. HRSG OPERATION AND MAINTENANCE Vibration Fatigue In locations where boiler tubes are welded to support lugs, a thick edge failure can form at the toe of the weld. This fracture is circumferential, running at right angles to the weld. The root cause is: • The vibration of the tube, caused by the steady flow of exhaust gases. • Along with a lug location that induces a rigid point that will concentrate the force into a short distance. Figure 7-11: Vibration Fatigue Appearance ALSTOM Power Copyright 2005 Project: NUBARIA POWER STATION I & II Revision: 0 04/02/05 7-20
  • 132. HRSG OPERATION AND MAINTENANCE Corrosion Fatigue Like the previous fatigue mechanism, cyclic stresses produce a series of parallel surface cracks, however this time the corrosive environment adds to the deterioration by forcing the oxide wedge into the cracks, further leveraging the fracture. The thick edge fracture will be coated with an oxide layer. Pits can often be found on the inside surface of the cracks. The causes have two key ingredients which are Corrosion and Stress. There is either induced stress from the way the tube connects to another pressure part or there is induced stress from the way the tube is tied to a structural support. • There is residual stress left over from fabrication. • Internal pits from dissolved oxygen or acidic corrosion from the pre-boiler circuit aggravate the cracking process in the water cooled tubes. • External corrosion in steam cooled units aggravates the cyclic flexing where the tube enters the header.
