Zwolinski and Wilhoit defined, in 1972, "gross" and "net" values for heats of combustion. In the gross definition the products are the most stable compounds, e.g. H 2O(l), Br 2(l), I 2(s) and H 2SO 4(l). In the net definition the products are the gases produced when the compound is burned in an open flame, e.g. H 2O(g), Br 2(g), I 2(g) and SO 2(g). In both definitions the products for C, F, Cl and N are CO 2(g), HF(g), Cl 2(g) and N 2(g), respectively. WebGross & Net Calorific Values Gross CVor ‘higher heating value’ (HHV) is the CV under laboratory conditions. Net CVor ‘lower heating value’ (LHV) is the useful calorific value in boiler plant. The difference is essentially the latent heat of the water vapour produced. Conversions – Units From kcal/kg to MJ/kg multiply kcal/kg by 0.004187
