Bituminous Coal Characteristics and Applications

Jan 14, 2019· Bituminous coal combustion releases more pollution into the air than subbituminous coal combustion, but due to its greater heat content, less of the fuel is required to produce electricity. As such, bituminous and subbituminous coals produce approximately the same amount of pollution per kilowatt of electricity generated.
