What are the types of coal? USGS,Bituminous: Bituminous coal is a middle rank coal between subbituminous and anthracite. Bituminous usually has a high heating (Btu) value and is the most common type of coal used in electricity generation in the United States. Bituminous coal appears shiny and smooth when you first see it, but look closer and you may see it has layers.
Coal Rank an overview ScienceDirect Topics,Coal rank is a measure of coal maturity and is the most fundamental parameter that relates both to the coalification history and the utilisation potential of a coal.
