Calorific Value | Glossary | Marquard & Bahls

Gross calorific value (H s) = net calorific value (H i) + condensation heat So the gross calorific value indicates how much energy can be released during the complete combustion of a given amount of fuel: It is comprised of the net calorific value plus the energy contained in the exhaust gases and in the water vapor produced during combustion.

Gasification-derived syngas differs from natural gas in terms of calorific value, composition, flammability characteristics, and contaminants. Oxygen-blown, entrained flow IGCC plants typically produce syngas with a heating value range of 250 to 400 Btu/ft 3 (HHV basis), which is much lower than the 1,000 Btu/ft 3 commonly associated with natural gas.
