WebThe higher heating value (also known gross calorific value or gross energy) of a fuel is defined as the amount of heat released by a specified quantity (initially at 25°C) once it is combusted and the products have returned to a temperature of 25°C, which takes into account the latent heat of vaporization of water in the combustion products. WebUnder 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: LHV = lower heating value of fuel in Btu/lb, HHV = higher heating value of fuel in Btu/lb, W = Weight % of moisture in fuel, and H = Weight % of hydrogen in fuel.

WebThe 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 hydrocarbon fuel is burned one product of combustion is water. WebCombustion of Black Liquor in the Recovery Boiler. The high heating value of black liquor is 13.5–15.0 GJ per t dry solids (tds). Hardwood black liquor contains 1.6–1.7 tds and softwood black liquor contains 1.8–1.9 tds per air-dried t of pulp. Combustion heat enables the production of high-pressure steam.
