So, if we take a coal sample andthen combust it in presence of sufficient amount of oxygen then it will release Heat,C+O2, CO2.And if hydrogen is available H + O2 is H2O so these are the basic reactions which generatesheat and that heat we are interested to get in useable form. So, heating value is obviouslythe amount of heat energy released ...
