Pulverised Fuel - an overview | ScienceDirect Topics
The wet coal is fed into a pulverizer along with hot gases drawn from the firing hood. The hot gas temperature is controlled by bleed air. The coal or coke is simultaneously dried and ground in the hot-air swept pulverizer. The pulverizer can be a hammer mill, ring-roll mill, or a ball mill type.
