  • Pulverised Fuelan 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.
