Fire and Explosion Prevention in Coal Pulverizing Systems

2018-2-1  COAL DUST FIRES AND EXPLOSIONS The pioneering effort to establish the relative ignition sensitivity and explosibility of air and various flam- mable dust mixtures was carried out by the U.S. Bureau of Mines over 60 years ago. Mine safety, and later, the safety of coal pulverizing systems, have received much detailed attention.

Airborne Dust Liberation During Coal Crushing

Airborne coal dust is also explosive, given the right particle size, concentration, and ignition source. Bureau of Mines studies have shown that ignitable airborne coal dust concentrations start on the order of 50g/m3 (0.05 oz./ft3) [5,6]. The most explosive coal dust size in air is below 75 nm (—200 mesh) [5,6]. Airborne coal dust
