The coal contains approximately 40 percent moisture and 12 percent ash. At full load, each unit fires approximately 900,000 lb/h of coal. The boilers are controlled circulation, radiant, single reheat, tangentially fired, balanced draft with divided furnace. Each boiler is equipped with eight mills feeding eight elevations of tilting fuel nozzles,

In power plants, PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area. These fans produce pressure upstream of the pulverize, to push the coal and air mixture through the pulverize into the furnace. Backward Curved Centrifugal Fan is the most common Centrifugal Fan used as a PA fan in a boiler power plant.
