Jan 31, 2009· Answers. Oldest Best Answer: 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 Kcals/kg, 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.
