Calorific Value Explained Definition of Calorific Value. Calorific value, often referred to as energy value, is the amount of energy per unit mass or volume released when a substance is completely burned.This metric is pivotal in fields such as energy production, where it determines the potential energy output from fuels like coal, oil, natural gas, and biomass.

However a part of the heat energy in the fuel is also used to convert the moisture in fuel to vapor. This part of the energy of the fuel is not taken into account while measuring the NCV but is captured in the GCV. Thus GCV is also called the Higher Heating Value (HHV) and NCV is called the Lower Heating Value (LHV).

Value (NCV), it is assumed that the products of combustion contained the water vapor and that the heat in the water vapor is not recovered. In other words, the NCV is derived from the GCV by deducting the latent heat of vaporization of water present and formed. Thus, NCV (MJ/kg.) = GCV (MJ/kg.) − 0.222 (% H) . . . (4.1)
