WebbTheoretical Calculation Of Calorific Value – Dulong’s Formula. If both hydrogen and oxygen are present, it may be assumed that all the oxygen are already combined with 1/8 of its weight of hydrogen to form water. This fraction is then deducted from the hydrogen content of the fuel in the calculation. WebbIf the composition of a fuel is known, the theoretical calculation of its calorific value can be done by using Dulong’s formula. Dulong assumed that the heat evolved comes from the combustion of C, H, & S present in the fuel and the calorific value of a fuel is the sum of the calorific values of these constituents.
