The coal is brought and crushed to powder. This is feed to Boiler for producing heat
In Boiler the water is converted to steam.
In Super heater the moisture content is removed from the steam and that steam is called super heated steam
The superheated steam rotates the shaft of the High pressure turbine
The Exhausted steam is sent to preheater and the steam then rotates the Intermediate pressure(IP) Turbine
The steam from the IP turbine is then feed to low pressure turbine.
The turbine shaft is connected to the Generator, which produces Electric Power.
The power generated is then Transmitted.
