Definition of subbituminous coal in English English dictionary

A dull, black coal of rank intermediate between lignite and bituminous coal

Dark-brown to black coal, intermediate in rank between lignite and bituminous coal. It contains less water and is harder than lignite, making it easier to transport, store, and use. It has lower heating value than bituminous coal, but its sulfur content is often low, so that a number of coal-fired electric-power plants have switched from bituminous to subbituminous coal and lignite (which also tends to have relatively low sulfur). Subbituminous deposits are found in the U.S., Canada, Brazil, Germany, Russia, Ukraine, Australia, and China

coal with 40% carbon and less sulfur than lignite

Dull, black coal that ranks between lignite and bituminous coal Its moisture content is between 20% and 30% by weight, and its heat content ranges from 7,800 to 9,500 Btus per pound of coal
