Power plantCoal fired


16/23

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.
