Jul 06, 2017· Coal Dust Hazards. For a fire to occur, the fire triangle needs to be present oxygen, fuel, and heat. An explosion happens when two other elements are added to the equation dispersion of dust and confinement of dust, as shown in diagram A. Oxygen and fuel cannot be avoided in a PRB coalfired power plant, but the heat source can originate from several different sources.

The major risk of fire is, for example, from the ignition of coal dust and deposits in case of Thermal Power stations, on the internal surface, walkways etc., of the conveyors or from the conveyor belt. Fire caused by friction of a defective part such as jammed roller, idlers resulting in subsequent localised overheating of the belt.
