Calorific Value
Also know as the heating value, Energy Value, and Fuel Content, the Calorific Value of a substance, usually a fuel or food items, is the amount of heat released during the complete combustion of a specified amount of it. The Calorific value is characteristic of each substance. It is measured in terms of heat energy liberated per unit quantity or the substance (usually mass) and the common units of it are: k cal/kg, kj/kg, j/mol, Btu/m3, Calorific value is commonly determined by use of a “Bomb Calorimeter’ in the context of Coal testing, Calorific value can be thought of as a rank-related parameter, but it also depends on the compositions of macerals and minerals.
