Young black coal with high moisture content of between 15 and 40 percent by weight. In the U.S. the most often cited example is the Power River Basin coal found in Wyoming and Montana. Heating value varies from 7,000 Btu/lb to slightly over 9,000 Btu/lb. This type of coal is considered by many to have the largest reserves by weight around the world. Countries such as Indonesia and Malaysia have much more subbituminous coal that bituminous coal. Sulfur value is typically quire low, and ash is also usually low. Volatile matter is usually high, and can exceed 40% of the weight of the cal “as received.”
