Smoldering coal from the silo reaches a point of deflagration (bursts into flames) as it travels through the feeder down to the mill. Raw coal supply is interrupted due to imprecise feeder control and stoppages above and below the feeder. Accumulation and settling in pulverizer components allow coal to dry – such.

Pulverizer Fire or Explosions - Innovative Combustion Technologies

All efforts must be taken to prevent coal from accumulating or settling in any of the pulverizer components. Dry coal that is allowed to remain in the pulverizer system can spontaneously ignite. Raw coal to the pulverizer must be uninterrupted and controllable. Precise feeder control and minimal stoppages above and below.

Pulverizer - Wikipedia

This regulation, by sweeping pulverized fuel from the mill, is very fast; comparable with oil firing response, but needs the coal level to be maintained in the mill. 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.
