coal explosion in pulverizer

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.
