Publisher - Always Right Answers To Community, The heating value of a fuel is the amount of heat released when the fuel is burned. Therefore: Natural gas is a fossil fuel that is formed when layers of buried plants and animals are exposed to intense heat and pressure over millions of years. The heat value of natural gas varies depending on the source, but is typically between 35 and 50 MJ/m. Natural gas has one of the highest net heating values per unit weight or volume compared to other fossil fuels up to 1,075 British thermal units per standard cubic foot (Btu/scf). The higher heating value (also known gross calorific value or gross energy) of a fuel is defined as the amount of heat released by a specified quantity (initially at 25C) once it is combusted and the products have returned to a temperature of 25C, which takes into account the latent heat of vaporization of water in the combustion products. For example, lets say we want to calculate both net and gross BTUs for propane gas (#2 on this table). As explained by FERC 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..
