Pulverizer - Wikipedia

A control circuit monitors the coal level in the mill, and controls the speed of the raw coal feeder to maintain it. Maintaining the coal level in the mill offers a built-in capacity cushion of pulverized fuel to take care of short interruptions in the raw coal circuit. The mill is pressurized and the air-tightness is ensured by plenum chambers around the rotating trunnion filled with pressurized seal air.
