Using Dulong and Vandralek Formulas to Estimate the Calorific Heating Value of a Household Waste Model

In this paper, Dulong, modified Dulong, Vandralek and direct formulas have been used to calculate the higher calorific value (HCV) and lower calorific value (LCV) of the waste model of the combustible fraction of the town of Ouagadougou. Different results from these formulas have been compared to experimental results obtained form measures made with a semi-industrial calorific heating value measurement apparatus. Comparison shows that the Dulong and Vandralek HCV formulas calculation gives us the lowest relative errors or differences in respect of the experimental LCV. On contrast, the direct LCV calculation formula give use the biggest relative error. This suggests that Dulong and Vandraleck formula could help quickly estimate the calorific value of a household waste combustible fraction model.
