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 due to the reduction in coal flow rate, as fuel moisture is reduced, the amount of ash entering the test burns with incrementally dried coal are needed for accurate determination of fuel moisture on NO x emissions.

feeder, therefore, discharged exactly 100 pounds of coal for each turn of the head pulley. Ihe head pulley speed was proportional to the rate of coal fed that could be expressed as pounds of coal per minute or pounds of coal per hour, as desired. Total turns of the feeder head pulley times 100 equaled the pounds of coat fed during any given period.
