Power plant boiler fuel demand is transmitted as a coal feeder speed demand to a coal pulverizer control. A speed controller operates the feeder in accordance with the speed demand, and a position controller for a hot coal transport air damper positions the hot air damper to hold the mill outlet temperature to a setpoint value and to increase or …

During a mill fire, pulverizer air flow should not be increased. Increased air flow could result in explosion. The procedure applied to extinguish a fire on an in-service pulverizer is as follows: 1. Increase the raw coal feed to the pulverizer to the maximum pulverizer capacity. 2. Make the transition from hot to cold air operation.
