Best answer: Which variety coal has high calorific value?

Anthracite (“coal-like”) is a hard, very low content of volatile compact variety of coal that has a high luster. It has the highest carbon content (between 92.1% and 98%), the fewest impurities, and the highest calorific content of all types of coal, which also includes bituminous coal and lignite.
