Thermal power plants

Thermal power plants

Thermal power plants are commonly used in India

A thermal power station is a power station in which heat energy is converted to electric power.

A steam-driven turbine converts heat to mechanical power as an intermediate to electrical power. Water is heated, turns into steam and drives a steam turbine which drives an electrical generator.

A coal based thermal power plant converts the chemical energy of the coal into electrical energy. This is a done by raising the steam in the boilers, expanding it through the turbine and coupling the turbines to the generators which converts mechanical energy into electrical energy.

Components of thermal power plant

Fundamental steam power plant components are Fuel handling plant, water treatment plant, ID fan, PA fan, Chimney, Water treatment plant, Steam Boiler system, Turbine, Mobrey Switch, Fusible Plug, Fluidized bed combustor, APH, economizer, generators, ash handling plant, dust collector system, condenser, cooling tower, feed water pump.

Advantages of thermal Power Plant

·         They can respond to rapidly changing loads without difficulty

·         A portion of the steam generated can be used as a process steam in different industries

·         Steam engines and turbines can work under 25 % of overload continuously

·         Fuel used is cheaper,Cheaper in production cost in comparison with that of diesel power stations
