Fire and Explosion Prevention in Coal Pulverizing Systems

In practice, a fire occurring during normal pulverizer operation does not result in an explosion. The rich coal/ air mixture has been shown to absorb the heat of the ignition source without igniting, and therefore it often produces no deflagration. The fire can be extinguished and the system brought off the line safely.
