Types of Centrifugal Fans Used in Power Plant | Blowerfab

PA fans give positive pressure upstream of the coal pulverizer and handle relatively clean air. 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 pulverizer, to push the coal and air mixture through the pulverizer into the furnace.
