coal rank - an overview | ScienceDirect Topics

Coal ranks of Mannville coals increase with depth westward and these range from medium- to low-volatile bituminous coals. Thus, the regional vertical and lateral variations in coal rank demonstrate the influence of sedimentary and tectonic burial as well as proximity to deformation where folding and faulting might have increased rank.

Bituminous Coal Characteristics and Applications

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.

Bituminous coal has a rank higher than that of the lignite coal and sub-bituminous coal, but a rank lower than that of the anthracite coal. The key distinguishing characteristics of bituminous coal are its relative VM and sulphur (S) content as well as its slagging and agglomerating characteristics.
