Coal Drying Improves Performance and Reduces Emissions

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), better conveying of coal in the coal pipes and less coal pipe plugging problems.
