Coal Drying Improves Performance and Reduces Emissions

Crushed coal is fed into the bunkers from where it flows by gravity to the coal feeders. Dryer coal flows more readily and causes less feeder hopper bridging and plugging problems. Coal feeders provide coal to the coal pulverizers (mills) where the coal is pulverized and dried. Dryer coal is easier to pulverize, and less mill power is needed to achieve the same coal fineness. Additionally, with less fuel .
