How to Calculate a Calorific Value | SciencingDeze pagina vertalen

The calorie content, or the calorific value, of a substance is the amount of energy that is liberated when the substance is completely "burned," or undergoes complete combustion.Combustion is one of the five basic types of chemical reactions, and it always occurs in the presence of oxygen gas (O 2), with the other reactant being some kind of (usually carbon-based) fuel.

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.

Notes: The lower heating value (also known as net calorific value) of a fuel is defined as the amount of heat released by combusting a specified quantity (initially at 25°C) and returning the temperature of the combustion products to 150°C, which assumes the latent heat of vaporization of water in the reaction products is not recovered.

Solid biomass fuels are more costly than coal, oil, and natural gas, even when compared on a simple gross calorific value (GCV) or net calorific value (NCV) basis. The cost disadvantage of solid biofuels is accentuated by the lower comparative efficiency of use in power generation, in synthesis gas production, and in direct heating systems.

No definite agreement is to be found in the literature on fuel as to whether the lower calorific value shall be found simply by subtracting latent heat of steam or both the latent heat and sensible heat in cooling from 100°C, from the gross calorific value of the fuel; in the latter case it would be necessary to fix the temperature to which the products are finally reduced.
