Pulverizer Fire and Explosions
Fires and Explosions. The presence of combustible materials in the pulverizer is usually the largest contributor to pulverizer fires. In most cases, pulverizer fires begin in the under bowl area of the pulverizer that is a very hot environment with an abundance of air. Accumulations of debris or coal anywhere in the pulverizer will increase the chance of a mill fire.
