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.

- Fuel Gases Heating Values
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.
29 Ιουν 2009 · If the water is in a gaseous phase, the heating value is referred to as net or lower heating value (LHV). If the water is in a liquid phase, the heating value is referred to as gross or higher heating value (HHV).
4 Νοε 2012 · Combustion heat values for gases like acetylene, blast furnace gas, ethane, biogas and more - Gross and Net values.
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.
We noted that standard deviations of methane volume fraction and lower heating value (LHV) of natural gas during a one month period were 0.68% and 0.71%, respectively, suggesting that the ...
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.
