Fire and Explosion Prevention in Coal Pulverizing Systems

2018-2-1  Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will

Fire and Explosion Risks in Cement Manufacturing Plants

2021-11-18  Coal storage should be considered in the hazard analysis. A coal fire can arise as a result of natural combustion caused by oxygen absorption at the outer and inner surface of coal leading to oxidation. Oxidation is an exothermic reaction that makes the temperature of the coal to go up and if the coal pile exceeds 800C, ignition can take place.
