Pulverized coal producing processes are widely used in thermal power stations, cement and iron-smelting industry. Many accidents and protection techniques have been reported by former investigations [1-3]. Normally, the traditional coal process systems use ball mills to pulverize coal. Flue gases are used as drying andThe most common heat transfer method for coal-fired boilers is the watertube method in which the hot combustion gases contact the outside of the heat transfer tubes, while the boiler water and steam are contained within the tubes. Coal-fired watertube boilers include pulverized coal, cyclone, stoker, fluidized bed, and handfed units.

The safety record and availability history of coal pulverizing systems in the electric utility industry is com- mendable.
