The Types of Coal: Composition, Usage, and Energy Value

 · The stored energy potential within coal is described as the "calorific value," "heating value," or "heat content." It''s measured in British thermal units (Btu) or millijoules per kilogram (MJ/kg). A Btu is the amount of heat that will warm approximately 0.12 U.S. gallons—a pound of water—by 1 degree Fahrenheit at sea level.
