Heat values of various fuels - World Nuclear Association
WebThe calorimetric value is significantly higher than the statistically calculated entropy, 186.26 J/mol*K, which remains the best value for use in thermodynamic calculations [ Vogt G.J., 1976, Friend D.G., 1989, Gurvich, Veyts, et al., 1989]. Earlier the value of 185.3 J/mol*K was calculated from experimental data [ Giauque W.F., 1931]. WebAnother key difference is in the oxygen-to-gas ratio required for proper combustion. LPG requires an oxygen-to-gas ratio of approximately 25 to 1. Natural gas requires a ratio of around 10 to 1. LPG is propane and butane while natural gas is methane. LPG is heavier than air while natural gas is lighter than air. WebNov 5, 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 expression can be ... peach gets locked in overnight
