Categories of coal
The International Coal Classification of the Economic Commission for Europe (UN/ECE) recognises two broad categories of coal: hard coal – coal of gross calorific value (CV) of >5700 kcal/kg (23.9 GJ/t) on an ash-free but moist basis and with a mean random reflectance of vitrinite of at least 0.6. Hard coal isTypes of Bituminous Coal . Thermal Coal: sometimes called steaming coal, is used to power plants that produce steam for electricity and industrial uses.

Bituminous is the most abundant rank of coal.There are four major types (or “ranks”) of coal. Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material.
