Mar 01, 2017· Lower calorific value means the total quantity of heat liberated from combustion of unit mass or unit volume of given fuel when side products are allowed to escape. Main difference is in higher calorific value heat losses to cool down but in lower calorific value there is no heat because side products (ash,volatile matter etc) escapes.

Lower and Higher Heating Values of Fuels | Hydrogen Too

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.

Mar 05, 2019· What is the difference between the “higher heating value” (HHV) and “lower heating value” (LHV) of a biomass fuel, and why is the difference important? 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.
