  • 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.
