Pulverizer Fire and Explosions

Explosions in a pulverized coal system are normally called "puffs." A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature. Mill puffs most often originate in the under bowl area and can cause very destructive damage to the primary air ducting.Explosion-Proof Vacuum Systems for .Superior filtration does not have to be sacrificed on an explosion proof model, especially when collecting potentially hazardous material like coal dust. For peak safety and operating efficiency, an EXP vacuum should have a multi-stage, graduated filtration system, which uses a series of progressively finer anti-static filters to trap and retain particles as they move through the vacuum.Power plant coal pulverizer has been generally .· In the grinding mill system of pulverized coal conveying gas, is due to the mixture of gas and coal dust, a spark will make the fire expand and produce greater pressure, resulting in coal dust explosion. So the mill model need to consider vertical mill explosion problem of coal grinding work.Fireproof and explosive-proof measures for coal .1. Installing explosive-proof valves and explosion-proof doors. 1) Explosive-proof valve should be installed on the pipeline of coal grinding system, so that when the explosion occurs, the gas pressure in the pipeline would be ventilated to avoid the possibility of more serious explosion accidents. 2) Explosion-proof doors should be installed ...Explosion-Proof Vacuum Systems for .Superior filtration does not have to be sacrificed on an explosion proof model, especially when collecting potentially hazardous material like coal dust.
