Coal-Fired Power Plants: Additional Hazards Require

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 coal-fired power plant, but the heat source can originate from several different sources.
