Fire and Explosion Risks in Cement Manufacturing Plants

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.
