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

Coal Gas Coal Mine Methane Coal Seam Methane Coal

Coal mine gas (firedamp) is a problematic phenomenon associated with coal mining, as the gas can form explosive mixtures together with air. The main component of the primary coal seam gas is methane in a concentration of 90-95 % the gas develops during the geochemical conversion of organic substances to coal (carbonisation). Coal seam gas is present both as liberated gas in fissures, faults

SPONTANEOUS COMBUSTION IN COAL COALspot

Spontaneous combustion has long been recognized as a fire hazard in stored coal. Spontaneous combustion fires usually begin as "hot spots" deep within the reserve of coal. The hot spots appear when coal absorbs oxygen from the air. Heat generated by the oxidation then initiated the fire. Such fires can be very stubborn to extinguish because of the amount of coal involved
