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.

### Lower calorific value - Energiteknik | KTH

Lower calorific value. Lower calorific value of a fuel portion is defined as the amount of heat evolved when a unit weight (or volume in the case of gaseous fuels) of the fuel is completely burnt and water vapor leaves with the combustion products without being condensed.

### 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.

### What is the significance of the heating value HHV and LHV .

The lower heating value (LHV) is defined as the net calorific value and is determined by subtracting the heat of vaporization of water vapor (generated during combustion of fuel) fromthe higher .
