### Energy value of coal - Wikipedia

The calorific value Q of coal [kJ/kg] is the heat liberated by its complete combustion with oxygen Q is a complex function of the elemental composition of the coal Q can be determined experimentally using calorimeters Dulong suggests the following approximate formula for Q when the oxygen content is less than 10%: Q = 337C + 1442(H - O/8) + 93S.
