Coal Dust Explosions in the Cement Industry. 218 INDUSTRIAL DUST EXPLOSIONS Phenomena of a Coal Dust Explosion To understand fully the hazards of using pulverized coal as a fuel in a cement plant, one must become familiar with the factors that typically enter into the development of an explosion.
Dust explosion, static electricity, spontaneous combustion, and hightemperature materials passing through the filters can cause fire or explosion. The bag filters used for coal mills pose the highest fire or explosion risks in cement plants due to the minute size of the crushed coal. Electrostatic Precipitators

COAL DUST EXPLOSION HAZARDS by CLETE R. STEPHAN, MINE SAFETY AND HEALTH ADMININSTRATION PITTSBURGH, PENNSYLVANIA ABSTRACT There are a large number of facilities throughout the world which handle coal, such as preparation plants. Many other facilities use coal as a fuel, such as cement and lime factories. Although
For many cement producers in the United States, the conversion from fuel oil and natural gas to pulverized coal has been difficult, frustrating, and in a few cases, very costly. This study deals mainly with coal safety requirements in the cement industry which accounts for a very small percentage of coal usage in pulverized coal firing systems.
