Coal mills or pulverizers play a very essential part in the coalfired power production system. Coal mills grind the coal into fine powder, and the primary air entering the mill dries and drives the coal into the power plant furnace for combustion. Mills can be a bottleneck for the power generation process.

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.
