    Coal Drying Improves Performance and Reduces Emissions

    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 (the temperature of the coal and primary air mixture at mill exit ...
