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.
