Definition
Superior calorific value: The energy released as heat energy by the complete combustion in air of a defined quantity of gas, in such a manner that the pressure p_c at which the reaction takes place remains constant,and all the products of combustion are returned to the same specified temperature T_c as that of the reactants, all of these products being in the gaseous state except for water formed by combustion, which is condensed to the liquid state at T_c. If the water is also returned to the gaseous state, the calorific value is labelled Inferior. See Draft International Standard ISO/DIS 14532 for additional details. The unit for the heating value has the dimension energy per volume or energy per mass or energy per mole, i.e. it always refers to a specific quantity of gas as described above. The test heating value is determined at a set of test conditions (temperature T1, pressure p1) for the metering of the quantity of the gas and at a set of test conditions (temperature T_c, pressure p_c) for the combustion process.
The system converts the test heating value either via standard ISO defined formulas to the base heating value or via customer user exits.
Examples:
For natural gas, typical values for the heating value are:
477 < HV/ BTU per cubic foot < 1211 ,
or
17.7725 < HV / MJ(Megajoule) per cubic meter < 45.12
