That depends on the state of water in the product of combustion. We refer to HHV when liquid water exists in the combustion products and LHV when water vapor exists in the combustion products. Numerically the difference between ...
carbon, hydrogen, nitrogen, sulfur and oxygen within the coal. Additionally, specific physical and mechanical properties of coal and particular carbonization properties are also determined. The calorific value Q of coal is the heat ...
Methanol 1 gallon = 64,600 Btu – HHV * 1 gallon = megajoules – HHV * 1 gallon = 56,560 Btu –LHV * 1 gallon = megajoules – LHV * 1 barrel = 2,713,200 Btu – HHV * 1 barrel = 2,862 megajoules – HHV * 1 barrel ...
The lower heating value (LHV) or higher heating value (HHV) of a gas is an important consideration when selecting a gas engine or CHP plant. Gas engines efficiency is typically quoted based upon the LHV of the gas. Whenever a ...
