Explain about functions of thermal power plant pa fan PA Fan is primary air fan which is used in power plant to push the coal from mill to furnace and to maintain the powdered coal always in dry state.
The coal power plant diagram shows the components of the plant and the different stages of transforming the chemical energy (coal) into electrical energy as: We started with the boiler or the steam generation system; as we supply the coal from coal bunkers via coal conveyors to be crushed into coal mills.
The pulverised coal from a mill is transferred through alternative flue gas to the cyclone separator, where the coal is separated and flue gas is sent back to the mill. The coal is then supplied to the burner feeder from where it is mixed with primary air and supplied to the burner for the combustion.
Coal fired power plants are a type of power plant that make use of the combustion of coal in order to generate use provides around 40% of the world''s electricity and they are primarily used in developing countries.
