    Calorific Value - an overview | ScienceDirect Topics

    A lower value can be derived, which is the gross calorific value minus the latent heat of condensation at 15.5°C of all of the water involved. This is named the net calorific value. The net calorific value is a more realistic statement of realizable potential heat than the gross value.

    What is the difference between gross and net calorific value?

    Dec 15, 2017· It is also known as Higher Heating Value (HCV). Net Calorific Value (NCV) also known as lower heating value (LHV) or lower calorific value (LCV) is determined by the subtracting the heat of vaporization of the water vapour from the higher heating value.This treats any H20 formed as a vapor. Natural gas prices are decided on the basis of GCV and NCV.

    Heat of combustion - Wikipedia

    Lower calorific value means the total quantity of heat liberated from combustion of unit mass or unit volume of given fuel when side products are allowed to escape. Main difference is in higher calorific value heat losses to cool down but in lower calorific value there is no heat because side products (ash,volatile matter etc) escapes.
