Web1 de mar. de 2024 · The higher heating values (HHVs) of the hydrocarbon compounds can be calculated based on the carbon (C) and hydrogen (H) contents of the chemical structures. HHVs (MJ / kg) as a function of the carbon (C) and hydrogen (H) fractions of N-saturated hydrocarbons can be calculated by the following equation: Web29 de mar. de 2024 · When this additional amount of energy is extracted from the flue products, causing the water to become liquid, the fuel's energy density is identified as higher heating value (HHV). When the equipment used allows the water to remain in the vapor state, the energy density is identified as lower heating value (LHV). Thus, Where:
