Lower Calorific Value (= Net Calorific Value - NCV = Lower Heating Value - LHV) - the products of combustion contains the water vapor and the heat in the water vapor is not recovered; The table below gives the gross and net heating value of fossil fuels as well as some alternative biobased fuels.
You can use this calculator to obtain the heating value of a given mass or volume of hydrogen or other fuels, or to calculate the mass or volume given a certain heating value. Choose whether you want to convert to heating value or to mass/volume, and then choose the fuel type.
Net calorific value (CV) or Lower Heating Value (LHV) given for all fuels. This means that the latent heat of vaporization of the water vapour created by combustion is not recovered by...
Online tool for calculating the calorific value of natural gas by composition.
The lower heating value (LHV), also known as the net calorific value (NCV), is defined as the amount of heat released by fully combusting a specified quantity less the heat of vaporization of the water in the combustion product.
The high heating value includes this energy. The lower calorific value doesn’t include the energy released in condensing water. This is why a gross calorific value is higher than a net calorific value. HHV = water vapour is condensed = more heat is recovered. LHV = water vapour remains as vapour – less heat is recovered
The first, called high heating value or HHV, includes the heat that can be obtained by condensing the water vapor that is released during combustion. The second, called low heating value or LHV, does not include this heat. The difference between HHV and LHV is typically about 10% for natural gas.
