Dec 17, 2018· 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.

A new formula for calculating the calorific value of coal from its ultimate analysis has been obtained by regression analysis of a data bank consisting of data on 775 samples of U.S. coals of all ranks. It yielded zero average difference between observed and calculated values and a standard deviation of 129 Btu/lb (300 kJ/kg).

Heat flows from the point of higher temperature to one of lower temperature. The heat content, Q, of an object depends upon its specific heat, c, and its mass, m. The Heat Transfer is the measurement of the thermal energy transferred when an object having a defined specific heat and mass undergoes a defined temperature change.

Heating Value. The lower heating value (LHV) or higher heating value (HHV) of a gas is an important consideration when selecting a gas engine or CHP plant.Gas engines efficiency is typically quoted based upon the LHV of the gas. Whenever a hydrocarbon fuel is burned one product of combustion is water.

The calorific value of a coal, which is usually termed the higher heating value (HHV) (also termed as the gross calorific value, GCV), is an important property for its use as a fuel. HHV is defined as the amount of heat released when a unit mass of the fuel is burnt completely, and the combustion products are cooled under standard conditions.

The energy density of coal, that is its heating value, is roughly 24 megajoules per kilogram (approximately 6.7 kilowatt-hours per kg). For a coal power plant with a 40% efficiency, it takes an estimated 325 kg (717 lb) of coal to power a 100 W lightbulb for one year.
