The energy value of coal, or fuel content, is the amount of potential energy it contains that can be converted into heat.This value can be calculated and compared with different grades of coal and other combustible materials, which produce different amounts of heat according to their grade.. While chemistry provides ways of calculating the heating value of a certain amount of a substance ...

The calorific value Q, of coal is the heat liberated by its complete combustion with oxygen. Q is a complex function of the elemental composition of the coal. Gross Calorific value Q is mostly determined by experimental measurements. A close estimate can be made with the Dulong formula: Q = (144.4 %[C])+(610.2 %[H])-(65.9 %[O])+(0.39 %[O]2) Q . is given in kcal/kg or Btu/lb. Values of the ...

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.

calorific value of coal is the heat liberated by its complete combustion with oxygen. Most applications which burn fuel produce water vapor which is not used, and thus wasting its heat content. In such applications, the lower heating value is the applicable measure. This is particularly relevant for natural gas, whose high hydrogen content produces much water. The gross calorific value is ...

Significance of Calorific Value It becomes clear from table given above that different fuels have different calorific values, i.e. different fuels produce different amounts of heat on burning. The calorific value of fuels helps us to decide that which fuel is good for us. This is done by comparing the calorific values of fuels with each other.
