FAQ - Alaska Company Inc
A common misconception of a coal stove is that it is dirty. It can be. It is all in how you handle your coal and your ashes. Keep the coal damp before you dump it into the hopper. This will eliminate any black dust. Pull your ash pan out of the stove half way, slowly, and mist the top of the ashes with water.

Spontaneous Combustion - an overview | ScienceDirect Topics
Sometimes air locks are installed between the feeder and the coal mill and these tend to cause coal hold up, which can result in loss of coal feed to the mill, thus introducing an explosion risk. This is caused by rapid increase in mill temperature that occurs when the heat sink created by the coal drying process is lost.
The Storm Approach to Coal Pulverizer Optimization
Once normal coal flow is applied to the mill, a full mill test should be conducted. This should include isokinetic coal sampling and dirty airflow measurements through each fuel line to determine air fuel balance and coal fineness. Primary airflow "Hot-K" calibrations of the primary airflow measuring element should also be conducted.
