In bituminous coals, specific plant components in the coal (macerals) become more homogenous, and the cell structures of woody material within the coal (still visible in lignite and subbituminous coals using scanning electron microscopy) become significantly deformed (Hatcher et al., 1994; Hatcher and Clifford, 1997). As a result of these ...

2020-1-29 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.

2021-3-10 It was documented that coal specific gravity (S.G) can be used to have an indirect estimation for the tonnage of productions. Since S.G varies based on coal rank, various coal ranks have different conversion factors (Table 1) (Wood et al. 1983). Moreover, S.G is a critical factor for the selection
