Fire and Explosion Prevention in Coal Pulverizing Systems

There is experimental evidence that coal dust/air mixtures do have a lower explosive limit (i.e., that concen- tration of coal in air below which an explosion does not occur), but do not have an upper explosive limit as long as the coal/ air mixture can be considered a cloud. In practice, a fire occurring during normal pulverizer
