Bituminous Coal Characteristics and Applications

Jan 29, 2020· Bituminous coal combustion releases more pollution into the air than sub-bituminous coal combustion, but due to its greater heat content, less of the fuel is required to produce electricity. As such, bituminous and sub-bituminous coals produce approximately the same amount of pollution per kilowatt of electricity generated.
