How to Calculate Calorific Value?
Two main values are used to calculate the calorific value: Gross Calorific Value (GCV) and Net Calorific Value (NCV). The Gross Calorific Value is the total heat produced during complete combustion, while the Net Calorific Value accounts for the heat used to vaporize water formed during combustion.
Calorific Value Formula
The formula for Net Calorific Value (NCV) is obtained by subtracting the Latent Heat of Water Vapors from the Gross Calorific Value (GCV). Alternatively, you can find the Gross Calorific Value by adding the Net Calorific Value to the Latent Heat of Water Vapors.
NCV = GCV – Latent Heat of Water Vapors
GCV = NCV + Latent Heat of Water Vapors
Calorific Value
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). In this article, we will cover the meaning and definition of calorific value, how to calculate with the formula of calorific value, calorific values of different fuels and food items.
