Enhancing Coal Mill Safety
The large surface area of the pulverised coal, as well as the high temperature inside the mill, leads to rapid oxidation of the coal. This results in further heat buildup and the potential for a fire. If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the air.

Fire and Explosion Prevention in Coal Pulverizing Systems
Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will be ground to a more uniformly fine size and dried to a greater extent. All these factors make the coal/ air mix- ture easier to ignite and, once ignited, more likely to detonate and cause an explosion.
