Types of Chimney in Power Plant: Chimney in Power Plant is used to release flue gas into the atmosphere. The chimney is constructed 2.5 to 3 times of height of the power plant. The main purpose of this is to emit the flue gas at a considerable height to avoid nuisance to the surrounding people. …
Electrostatic Precipitator (ESP) – Construction and Working Principle: Electrostatic Precipitator is located between the boiler and the chimney, it extracts the fly ash from the flue gases and thus prevents the fly ash from entering the atmosphere. Electrodes are used to attract the fly ash when the flue gas coming out of the boiler is …

Subsystems of Thermal Power Plant: The Subsystems of Thermal Power Plant are the auxiliary plants required for the plant for its proper operation and for the increase of their efficiency. Some of the sub systems are as follows: Boiler Accessories: The appliances used to increase the efficiency of the boiler are known as boiler accessories. …
Steam Condenser – Definition, Working Principle and Types: Steam condenser is a device in which the exhaust steam of a turbine is condensed by means of cooling water below atmospheric pressure. By decreasing the exhaust pressure of steam below atmosphere, the efficiency of the power plant is greatly improved. The condensed steam is called condensate …

Steam Turbine Working Principle and Types: Steam turbines are one of the most versatile and oldest prime movers that transform the potential energy of the steam into kinetic energy and later in turn transformed into mechanical energy – rotation of turbine shaft. Working principle: The steam energy is converted into mechanical work by expansion through …
Pressurised Fluidised Bed Combustion System (PFBC): Pressurised Fluidised Bed Combustion (PFBC) system is used for large coal burning applications. The operating efficiency of PFBC is increased by introducing differential air pressure. In PFBC, coal is injected into pressurized bed of 850 – 900°C. The bed consists of 90 – 95% of coal ash and desulphurisation …

Bubbling Fluidized Bed Combustion System: In Bubbling Fluidized Bed Combustion System (or) Atmospheric bed combustion system, coal is crushed to a size of 1 – 10 mm depending upon the quality of coal and type of fuel fed into the combustion chamber. Air is used for both fluidization and combustion. Air is allowed to pass …
Fluidized Bed Combustion Boiler Working and Types: The coal available in India is of low quality, high ash content and low calorific value. The traditional grate fuel firing systems have got limitations and are techno-economically unviable to meet the challenges of future. Fluidized Bed Combustion Boiler has emerged as a viable alternative and has significant …
