The coal is usually stored in the bunker before feeding, and the flow of coal is controlled by a gate valve. After coal is fed into the feeder it passes through the conveyor belt and enters the coal mill where it gets converted into a fine particle, mixed with an equal quantity of air, and finally used for combustion inside the furnace.
