Higher heating value of hydrogen

Webexcluding from the higher heating value of such fuels “the latent heat of water vapor formed in the combustion of hydrocarbon fuels.” See 45 FR 17962. Under this formula, the relationship between the lower heating value of a fuel and the higher heating value of that fuel is: LHV = HHV – 10.55(W + 9H) Where: WebFood - Calorific Combustion Values - Combustion heat values of some foods. Fuel Gases - Combustion Values - Combustion values for fuel gases like natural gas, propane and butane - Btu per cubic feet. Fuel Gases - Heating Values - Combustion heat values for gases like acetylene, blast furnace gas, ethane, biogas and more - Gross and Net values.
