Boilers
This document discusses different types of boilers. It begins by explaining that a boiler produces steam using the thermal energy released from fuel combustion. It then describes the common uses of steam and some key properties of boilers. The document goes on to classify boilers based on whether they use fire tubes or water tubes to transfer heat. Several specific boiler designs are outlined, including their features and advantages. Key metrics for evaluating boiler performance like evaporative capacity and efficiency are also defined.
Power plant engineering
Boilers produce steam using heat from the combustion of fuel. There are various types of boilers classified based on their orientation, heating method, circulation type, pressure, portability, and number of tubes. Fire tube boilers have hot gases passing through tubes surrounded by water, while water tube boilers have water passing through tubes surrounded by hot gases. Water tube boilers generally have higher steam pressure and production capacity compared to fire tube boilers. Common boiler types discussed in the document include fire tube boilers like Lancashire and locomotive boilers, and water tube boilers like Babcock & Wilcox. Boilers require safety devices like safety valves, water gauges, and pressure gauges.
Pit furnace
A pit furnace is constructed by digging a pit and building a furnace structure within it. The furnace body is made of steel plates lined with ceramic fiber insulation. It has a lid with a central fan for circulating gases. Pit furnaces can be used to melt metals by placing crucibles containing metal inside. Coke fuel is burned to heat the furnace to the desired temperature for processes like carburizing, hardening, annealing, and nitriding steel parts. Pit furnaces provide flexibility, economic operation, and precision for heat treating large loads.

The modular design uses locally available materials and is affordable, durable, and easy to use. Testing showed it reduces fuel use by 50% and emissions while cooking twice as fast as an open fire. Future recommendations include adding a heat exchanger or thermoelectric generator to increase efficiency.
Steam Boilers
The document discusses two types of boilers: the Cochran boiler and the Lancashire boiler. The Cochran boiler is a vertically oriented boiler with multiple fire tubes. It can generate steam at low rates up to 4000 kg/hr at 6.5 bar pressure. The Lancashire boiler is a horizontally oriented boiler also with multiple fire tubes. It can generate more steam at 9000 kg/hr at a maximum pressure of 16 bar. Both boilers work by heating water into steam using hot gases that pass through internal fire tubes, but the Lancashire boiler utilizes three phases of flue gases to increase its heating surface area.
Water and fire tube boilers
Boilers produce steam using heat from fuel combustion. Water tube boilers have tubes that carry water and shells that carry hot gases, allowing for higher steam pressures and capacities than fire tube boilers which have tubes that carry hot gases and shells that carry water. Key components of boilers include shells, burners, drums, furnaces, safety valves, and feed pumps. Boilers are classified by their tube configuration and common types include water tube, fire tube, and vertical or horizontal orientations. Water tube boilers have advantages over fire tube in steam generation speed, capacity, efficiency and maintenance access.

Thermal Engineering - II
Industrial boilers are closed vessels made of steel used to generate steam through combustion of fuels like coal. They are classified based on orientation (vertical or horizontal), firing method (internally or externally), and tube configuration (fire tube or water tube). Key boiler types include vertical boilers, Cochran boilers, Lancashire boilers, locomotive boilers, Babcock & Wilcox water tube boilers, and high pressure boilers. Proper mountings and accessories are needed for safety, control, and efficiency. Modern trends favor high-capacity, high-pressure water tube boilers.
Unit II boiloers and its mountings
This document discusses steam boilers, their classifications, components, and accessories. It begins by defining steam generators/boilers as equipment used for producing and transferring steam. It then classifies boilers based on factors like the relative position of hot gases and water, method of firing, pressure, circulation method, and intended use. Examples of fire tube and water tube boilers are described in more detail, including locomotive, Lancashire, and Babcock & Wilcox boilers. Mountings for safety and control are outlined. Finally, essential characteristics of a good boiler and common accessories are summarized.

02 Boiler Construction.ppt
- Water tube boilers have greater mechanical flexibility and efficiency compared to fire tube boilers. They are better suited for high pressure and temperature applications like power generation.
- D-type boilers have superheater tubes located in the high temperature furnace region, leading to more failures. ESD boilers move the superheater outside the furnace for better performance and life. ESD-III uses water attemperation and roof firing for best results.
- Reheat boilers increase efficiency by reheating steam, reducing plant size for same output. However, protection during maneuvers and complex installation are disadvantages.
