Jan 31, 2009 Calorific value is the amount of heat energy released by burning one kg of a fuel. For example if the calorific value of a particular quality coal is given as 4500 Kcalskg, it implies by burning 1kg of coal 4500 Kcalories of heat energy is released. The more the ash content in the coal the lesser is the calorific value.
