Gross and net 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 … See more The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it. The calorific value … See more Engine manufacturers typically rate their engines fuel consumption by the lower heating values since the exhaust is never condensed in the … See more The International Energy Agency reports the following typical higher heating values per Standard cubic metre of gas: • Algeria: 39.57 MJ/Sm • Bangladesh: 36.00 MJ/Sm See more The higher heating value is experimentally determined in a bomb calorimeter. The combustion of a stoichiometric mixture of fuel and oxidizer … See more The difference between the two heating values depends on the chemical composition of the fuel. In the case of pure carbon or carbon … See more Both HHV and LHV can be expressed in terms of AR (all moisture counted), MF and MAF (only water from combustion of hydrogen).
