Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

Sub bituminous coal has a heating value between 8300 and 13000 British Thermal Units per pound on a mineral-matter-free basis. On the basis of heating value, it is subdivided into sub bituminous A, sub bituminous B, and sub bituminous C ranks. Bituminous.
