GCV is calculated by measuring the heat produced when a fuel is burned in a constant volume calorimeter, while NCV is calculated by subtracting the heat lost through the exhaust gases from the GCV.

Calorific Value: Definition, Formula and Calorific Values of Fuels

Calorific value is the amount of energy released when a specific quantity of a substance, typically a fuel or food, undergoes complete combustion or metabolism. It is measured in units such as kilojoules (kJ) or kilocalories (kcal).

Energy Sector

• for coal and oil, the NCV is about 5 % less than the GCV • for most natural and manufactured gas, the NCV is about 10 % less o Where fuel characteristics (moisture, hydrogen and oxygen contents) are known, the 2006 IPCC Guidelines give a more precise method to convert GCV to NCV data: NCV = GCV − 0.212H − 0.0245M − 0.008Y

CDP Technical Note: Conversion of fuel data to MWh

Net Calorific Values (NCV) = 11.9 TJ/Gg Expression to calculate Energy: Energy = Mass * NCV Step 2 – Analyzing the units of the parameters in the equation Coal is expressed in metric tons and we want to obtain Energy in MWh. The NCV is given in TJ/Gg, so we need to transform it to MWh/t. For that the following reasoning can be applied:

Gross Calorific Value vs. Net Calorific Value

Similar to GCV, NCV is typically measured in units of kilojoules per kilogram (kJ/kg) or British thermal units per pound (BTU/lb). NCV is particularly useful in applications where the heat generated is not fully utilized, such as in open fires or certain heating systems. By excluding the latent heat of vaporization, NCV provides a more ...
