Heat of combustion - Wikipedia

The quantity known as higher heating value (HHV) (or gross energy or upper heating value or gross calorific value (GCV) or higher calorific value (HCV)) is determined by bringing all the products of combustion back to the original pre-combustion temperature, and in particular condensing any vapor produced.

Lower and Higher Heating Values of Fuels Hydrogen Tools

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 25°C) once it is combusted and the products have returned to a temperature of 25°C, which takes into account the latent heat of vaporization of water in the combustion products. Btu = British thermal units; scf = standard cubic ...

Estimation of higher heating value of coal based on ...

01/10/2015  The calorific value of a coal, which is usually termed the higher heating value (HHV) (also termed as the gross calorific value, GCV), is an important property for its use as a fuel. HHV is defined as the amount of heat released when a unit mass of the fuel is burnt completely, and the combustion products are cooled under standard conditions. Presently, the HHV of coals is usually determined ...

Heat values of various fuels - World Nuclear Association

Heat Values of Various Fuels. The heat value of a fuel is the amount of heat released during its combustion. Also referred to as energy or calorific value, heat value is a measure of a fuel's energy density, and is expressed in energy (joules) per specified amount (e.g. kilograms). Heat value: Hydrogen (H 2) 120-142 MJ/kg: Methane (CH 4) 50-55 MJ/kg: Methanol (CH 3 OH) 22.7 MJ/kg: Dimethyl ...

How to Calculate Higher Heating Value Hunker

Higher heating value (HHV) is one measure of the energy content of a material. It is almost exclusively used in measuring energy content for fossil fuels and their alternatives, such as oil, coal, natural gas and biomass. HHV is the upper end of the energy content, and it includes the energy in water evaporated from the fuel as it is combusted. True HHV must be determined from experimentation ...

05/03/2019  We need these two ways of expressing the heating value of fuels because the combustion of some hydrogen-rich fuels releases water that is subsequently evaporated in the combustion chamber. In other words, the process of evaporating water “soaks up” some of the heat released by fuel combustion. That heat, known as the “latent heat of vaporization,” is temporarily lost and therefore
