Subbituminous coal | coal classification | Britannica.com

Although subbituminous coal has lower calorific values than bituminous coal, its sulfur content is often low, sometimes less than 1 percent. Since subbituminous coal has a much lower calorific value than the same amount of a bituminous coal, more subbituminous coal must be burned to obtain the same amount of energy.
