Anthracite or Bituminous

Jun 23, 2021Sub-bituminous coal - This is a medium soft coal that contains much less moisture than lignite and is not nearly as crumbly. Like lignite, its primary use is in the generation of electricity. The carbon content of sub-bituminous coal runs from 35%-45% and its heat value generally ranges from 8,000-13,000 Btu's per pound.
