Coal Drying Improves Performance and Reduces Emissions
· 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 moisture more complete drying of coal can be achieved in the mill. This results in increased mill exit temperature
