Calculating the Heat of Combustion for Natural Gas The heat produced by the combustion of a fuel is called its heating value, which is equal to the value of ∆Hcomb but of opposite sign. When liquid water is the product, it is called the higher (or gross) heating value (HHV). Heat of Combustion – Neutrium The heat of combustion is typically presented in the form of a heating value. The heating value is the amount of energy released during combustion and can be referenced as a higher or lower heating value.

Calorific Value, Calorie Conversion Calculator - Ask Numbers
The calorific value or energy density (heating value) of a substance (fuel, coal, gasoline, food etc) is the amount of heat released during the combustion of a specific amount of it. Calorific values are measured by units of energy (calorie, joule, btu etc) per unit of substance.
Heating Values of Natural Gas - EnggCyclopedia
The heating value of a substance is the energy released upon combustion of a substance at standard conditions. The heating value can be measured as energy released per unit mass, unit volume or unit mole of a substance. For mixtures, the heating value can be estimated as a weighted sum.
