Coal type determines the composition of coal and it reflects the degree of oxidation during coalification. Based on the van Krevelen diagram (van Krevelen, 1993), coal consists of three key material groups including vitrinite, liptinite and inertinite, which are composed of distinct constituents called macerals. Table 14.2 compares the key characteristics of coal macerals (van Krevelen, 1993).

Processing the Coal. After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Source: Energy Information Administration

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.
