Incident Summary Unit 3 experienced an unplanned extended outage beginning August 4, 2009. As a result of the shutdown, the seven coal bunkers that feed Unit 3 had remaining inventory and were nearly full. Normal procedure for an extended Unit shutdown involves the emptying of the bunkers to minimize risk of a coal fire by oxidation.

The design "capacity" of the same pulverizer will grind 135,000 pounds per hour with fuel that is 55 HGI (Hardgrove Grindability Index) coal, ¾" raw coal top size, 7% moisture and produces pulverized coal that is 70% passing 200 mesh fineness (red line). This is pretty standard.
Coal is often the main fuel source used to heat the cement kiln. Coal pulverizers are required to grind the coal from the bulk storage size to a smaller particle diameter to use in the kiln. Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire/explosion hazard risk.

The coal mill scrapers will usually sweep the fuel pieces around to the debris chute and discharge them; however, a fire is likely to occur if a coal buildup occurs at the hot air inlet to the mill. Hot surfaces. Hot surfaces such as hot bearings, cutting, or welding can start a coal dust fire or explosion.
