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 ...

Modelling and control of pulverised fuel coal mills

An area of power plant control that has received much less attention from mod elling and control specialists is the coal mills. This is in spite of the fact that it is now accepted that coal mills and their poor dynamic response are major factors in the slow load take-up rate and they are also a regular cause of plant shut-down (Maffezzoni, 1986).

Pulverizers 101: Part 3

- the air that moves the pulverized coal from the mill to the furnace. For bituminous coals, the primary airflow, at optimum, may be as little as 15% of the total air for combustion. This is based on 13,000 Btu/lb fuel that requires 12 lbs of air per lb of fuel for complete combustion. PRB fuel with a HHV of 8,500 Btu/lb will require about
