Heat of combustion

The higher heating value takes into account the latent heat of vaporization of water in the combustion products, and is useful in calculating heating values for fuels where condensation of the reaction products is practical (, in a gasfired boiler used for space heat). In other words, HHV assumes all the water component is in liquid state at the end of combustion (in product of combustion ...

What is the difference between gross and net calorific value?

It is also known as Higher Heating Value (HCV). Net Calorific Value (NCV) also known as lower heating value (LHV) or lower calorific value (LCV) is determined by subtracting the heat of vaporization of the water vapour from the higher heating value. This treats any H 2 0 formed as a vapor. Natural gas prices are decided on the basis of GCV and NCV. Did you find it helpful? Yes No. Send ...

 · We need these two ways of expressing the heating value of fuels because the combustion of some hydrogenrich 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 does ...
