Types of Centrifugal Fans Used in Power Plant | Blowerfab

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. Backward Curved Centrifugal Fan is the most common centrifugal fan used as a PA fan in a boiler power plant.

Coal Mill - an overview | ScienceDirect Topics

In coal milling for power stations, a 'closed-loop' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.
