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.

Evaluation of Heat Rates of Coal Fired Electric Power Boilers

coal-fired power plants. Heat rate is the amount of heat input from fuel per unit of net power output. Because heat rate is the inverse of efficiency, a lower heat rate signifies a more efficient electric generating unit. Methods to improve (lower) a unit's heat rate generally fall into three categories:
