Calorific Value
The calorific value defines the energetic content of the materials; it is the amount of heat a substance produces after complete combustion. You can express it as the gross calorific value (GCV) or high heating value. Also, the calorific value of a substance (generally, solid biofuel or food) is the specific energy of combustion for a unit mass.
GCV vs. NCV
GCV (Gross Calorific Value) and NCV (Net Calorific Value) are both measures of the amount of energy released when a fuel is burned. The main difference between the two is that GCV includes the latent heat of vaporization of water in the combustion products, …
