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

Pulverised Coal Combustion

Pulverised Coal Combustion. In PCC furnaces, both the fuel and the oxidizer emanate from fixed ports, which makes it logical to track the combustion process along a time coordinate, albeit from a macroscopic rather than a microscopic perspective.
