High heating value formula
Web5 de nov. de 2001 · The higher and lower calorific values of a fuel are related by the following expression: Q L = Q H – 2454 ( W + 9H ) (1) Where: Q L = Lower Calorific Value (kJ/kg) Q H = Higher Calorific Value (kJ/kg) W = wt% moisture in fuel/100. H = wt% hydrogen in fuel/100. Alternatively, using units of Btu/lb for the calorific value, the … WebThe net or lower heating value is obtained by subtracting the latent heat of vaporization of the water vapor formed by the combustion from the gross or higher heating value. …
