Jul 04, 2021 Natural gas is sold on the HHV basis. Lower Heating Value . By contrast, the Lower Heating Value (LHV) is the HHV minus the latent heat of vaporization of the water vapour formed by the combustion of the hydrogen in the fuel. A rule of thumb for natural gas is HHV = LHV x 1.11. Daily HHV Google Google.احصل على السعر

Mar 01, 2020 HHV can be determined by bringing all the products of combustion back to the original pre-combustion temperature while allowing any produced vapour to condense. Meanwhile, LHV can be determined by subtracting the heat of vaporization of water from the higher heating value. So, this is the key difference between HHV and LHV. Reference: 1.احصل على السعر
The lower heating value (also known as net calorific value) of a fuel is defined as the amount of heat released by combusting a specified quantity (initially at 25°C) and returning the temperature of the combustion products to 150°C, which assumes the latent heat of vaporization of water in the reaction products is not recovered.احصل على السعر
Answer (1 of 2): Energy content or calorific value is the same as the heat of combustion, and can be calculated from thermodynamical values, or measured in a suitable apparatus: A known amount of the fuel is burned at constant pressure and under standard conditions (0°C and 1 bar) and the heat r...احصل على السعر
