Chapter 7 COAL

coals because it reduces the heating value (water does not burn!) and its weight adds to the transportation costs of coal. This is a problem for the lowsulfur subbituminous coals from Wyoming, which are currently very popular with electric power plants (see Investigations 72 and 73). When a coal sample that has been dried to remove its moisture is heated in the absence. environmental pollut
