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.

6. Lower air flow means and a greater tendency to plug with wet coal. 7. Lower air flow leaves more reserve fines in the pulverizer. 8. Also note that lower air flow leaves a deeper bed depth of coal, and thus a higher pulverizer d/p. Keeping the PA flow above minimum line velocity is a very important safety consideration. A
