What are the types of coal? usgs.gov

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.

Coke (fuel) Wikipedia

Coke is commonly used as fuel for blacksmithing.. Coke was used in Australia in the 1960s and early 1970s for house heating. Since smoke-producing constituents are driven off during the coking of coal, coke forms a desirable fuel for stoves and furnaces in which conditions are not suitable for the complete burning of bituminous coal itself.
