Gross calorific value
The term ‘calorific value’ (CV) is a measure of heating power, and refers to the amount of energy released when a fuel is completely combusted under specific conditions. For solid and liquid fuels this is measured at constant volume and for gaseous fuels it is measured at constant pressure.
- The Net Calorific Value considers that the combustion products contain water of combustion to the vapour state, and so the heat energy in the water is not recovered.
- The Gross Calorific Value considers that the water of combustion is condensed, and so the heat energy in the water is recovered.
