STEAM TURBINES AND ITS GOVERNINGS
This document discusses different types of steam turbines based on their operating principles and design. Steam turbines can be classified based on how steam expands through the turbine (impulse, reaction, or a combination), the number of pressure stages, the direction of steam flow, the number of cylinders, the method of governing steam flow, the steam conditions, and their application in stationary or non-stationary systems. Common types include impulse, reaction, and mixed-flow turbines. The document compares impulse and reaction turbines and discusses methods for reducing turbine speed under varying loads.
Steam turbine and its types
This document discusses the Rankine cycle, which is a thermodynamic cycle derived from the Carnot vapor power cycle. It consists of four processes: 1) Isobaric heat supply in the boiler where water is heated to high pressure steam, 2) Adiabatic expansion of the steam in a turbine to produce work, 3) Isobaric heat rejection in the condenser where the steam is condensed back to water, and 4) Adiabatic pumping of the condensate back to the boiler to complete the cycle. The heat and work transfers are also defined for each process.
Steam turbine Working
Steam turbines work by converting the energy of expanding steam into rotational motion. They have several key components and come in two main types: impulse and reaction. Impulse turbines use nozzles to direct high velocity steam onto turbine blades for impulse, while reaction turbines utilize both fixed and moving blades to expand steam. Common problems in steam turbines include stress corrosion cracking, corrosion fatigue, thermal fatigue, and pitting due to chemical attack from corrosive elements in the steam. Proper lubrication and preventing blade deterioration are important for optimizing steam turbine performance and lifespan.

More stages are needed compared to impulse turbines of the same capacity due to the pressure drops at each stage. Compounding methods like velocity, pressure, and pressure-velocity compounding are used to reduce the rotor speed to an optimum value by absorbing steam pressure or velocity in stages.

Gas turbines
1. A gas turbine uses a gaseous working fluid that is compressed in a compressor, heated in a combustion chamber, and expanded through a turbine to produce mechanical power.
2. Early gas turbines had low efficiency but could start quickly, so they were used to provide peak power loads. Improved materials and cooling techniques have increased efficiency over time.
3. The ideal gas turbine cycle is known as the Joule-Brayton cycle and consists of isentropic compression, constant pressure heating, isentropic expansion, and isobaric closure back to the initial state.
Steam Turbine_edit.pptx
1. A steam turbine uses the potential energy of steam to rotate a shaft. In an impulse turbine, steam expands only in fixed nozzles and strikes moving blades, changing direction but not pressure. In a reaction turbine, steam expands gradually in both fixed and moving blades as it passes over them.
2. A De Laval turbine is a simple impulse turbine with one set of nozzles. It has a high rotor speed due to absorbing all kinetic energy in one set of blades. Compounding methods like pressure and velocity compounding are used to reduce rotor speed.
3. The basic components of a steam turbine are nozzles, rotor blades, casing and shaft. Impulse turbines use the kinetic energy of steam to rotate
Summer 2015 Intern Report
The document proposes replacing pressure reducing valves (PRVs) with backpressure steam turbine-generators at a heat plant to increase efficiency. Currently, PRVs reduce steam pressure from 180 psig to 25 psig without recovering work. Installing a turbine would capture this pressure reduction as electricity. Calculations show the turbine cycle would achieve an efficiency of 77.2% versus 76.6% for the PRV cycle. Case studies at other universities found turbines reduced emissions by 1,200-2,000 metric tons annually and saved $120,000-275,000 per year. A pre-design analysis identified space in the plant basement as optimal for a turbine, which could fit through double doors and utilize existing steam piping.
Mini project ppt on working of steam turbine and its auxiliaries

Steam Turbines & Gearing (GJ ROY).pdf
This document provides an overview of different types of steam turbines used in maritime applications. It discusses the basic design and operation of impulse turbines, impulse-reaction turbines, and pressure compounded turbines. Impulse turbines only utilize changes in steam direction to turn the turbine, while impulse-reaction turbines also utilize pressure drops across the blades. Pressure compounded turbines split the overall pressure drop into multiple smaller stages to reduce steam velocities to practical levels for ship propulsion. The document also covers nozzle design and how it controls the expansion of steam to convert heat energy to kinetic energy for driving the turbine.
MODULE-V_STEAM TURBINES.pptx
1) A steam turbine uses the dynamic action of steam to convert the energy of high pressure and high temperature steam into mechanical power. Steam is expanded in nozzles which converts pressure energy to kinetic energy.
2) There are two main types of steam turbines - impulse turbines which use the kinetic energy of steam and reaction turbines which use continuous pressure drop of steam as it passes through fixed and moving blades.
3) Compounding involves arranging steam expansion in multiple stages to reduce rotor speed. Methods include velocity compounding using multiple moving blades, pressure compounding with partial expansion at each nozzle, and pressure-velocity compounding combining both.
Gas turbine

3. The two cycles discussed are the open cycle and closed cycle. The document also examines improvements like regeneration, reheating and intercooling processes and their effects on efficiency.
Ppt
The document summarizes the Suratgarh thermal power station located in Rajasthan, India. It has a total installed capacity of 1500 MW generated across 6 stages. It uses coal from local mines to power steam turbines that generate electricity. Raw coal is pulverized and burns in the boiler furnace to heat water and create steam. This high-pressure steam powers the turbines which are connected to generators to produce electricity. The steam is reused through reheating and condensing in a closed loop system.
Reverse rotaion of co2 compressor
The document describes an issue of reverse rotation observed in CO2 compressors of a urea production plant in India. During shutdown, the pressure differential across stages caused gas to flow in reverse, spinning the compressor rotor backwards. This posed risks like vibration, damage to seals and bearings. Modifications were made to valves controlling gas recycle and venting to prevent pressure build up. Opening a valve from the 2nd discharge to 1st suction during trips helped reduce reverse gas torque, keeping rotation in the forward direction. These changes resolved the reverse rotation seen during shutdown of the CO2 compressors.

- 6. Description of common types of Turbines. 1. Impulse Turbine. 2. Reaction Turbine. The main difference between these two turbines lies in the way of expanding the steam while it moves through them. 6 KHIT, Guntur
- 8. In the impulse turbine, the steam expands in the nozzles and it's pressure does not alter as it moves over the blades. In the reaction turbine the steam expanded continuously as it passes over the blades and thus there is gradually fall in the pressure during expansion below the atmospheric pressure. 8

- 14. Reaction Turbine In this type of turbine, there is a gradual pressure drop and takes place continuously over the fixed and moving blades. The rotation of the shaft and drum, which carrying the blades is the result of both impulse and reactive force in the steam. The reaction turbine consist of a row of stationary blades and the following row of moving blades 14
- 15. The fixed blades act as a nozzle which are attached inside the cylinder and the moving blades are fixed with the rotor as shown in figure When the steam expands over the blades there is gradual increase in volume and decrease in pressure. But the velocity decrease in the moving blades and increases in fixed blades with change of direction. 15 KHIT, Guntur
- 16. Because of the pressure drops in each stage, the number of stages required in a reaction turbine is much greater than in a impulse turbine of same capacity. It also concluded that as the volume of steam increases at lower pressures therefore the diameter of the turbine must increase after each group of blade rings. PES16

- 22. .Compounding in Steam Turbine. The compounding is the way of reducing the wheel or rotor speed of the turbine to optimum value. Different methods of compounding are: 1.Velocity Compounding 2.Pressure Compounding 3.Pressure Velocity Compounding. In a Reaction turbine compounding can be achieved only by Pressure compounding.22 KHIT, Guntur
- 23. Velocity Compounding: There are number of moving blades separated by rings of fixed blades as shown in the figure. All the moving blades are keyed on a common shaft. When the steam passed through the nozzles where it is expanded to condenser pressure. It's Velocity becomes very high. This high velocity steam then passes through a series of moving and fixed blades. When the steam passes over the moving blades it's velocity decreases. The function of the fixed blades is to re-direct the steam flow without altering it's velocity to the following next row moving blades where a work is done on them and steam leaves the turbine with allow velocity as shown in diagram.23
- 25. Pressure Compounding: These are the rings of moving blades which are keyed on a same shaft in series, are separated by the rings of fixed nozzles. The steam at boiler pressure enters the first set of nozzles and expanded partially. The kinetic energy of the steam thus obtained is absorbed by moving blades. The steam is then expanded partially in second set of nozzles where it's pressure again falls and the velocity increase the kinetic energy so obtained is absorbed by second ring of moving blades. 25
- 27. Pressure velocity compounding: This method of compounding is the combination of two previously discussed methods. The total drop in steam pressure is divided into stages and the velocity obtained in each stage is also compounded. The rings of nozzles are fixed at the beginning of each stage and pressure remains constant during each stage as shown in figure. The turbine employing this method of compounding may be said to combine many of the advantages of both pressure and velocity staging By allowing a bigger pressure drop in each stage, less number stages are necessary and hence a shorter turbine will be obtained for a given pressure drop. 27
