WebHigh Heating Value HHV refers to the energy released in combustion when condensing the water vapor resulting from the combustion, causing latent heat evaporation as a result. … WebHeat of combustion depends on the relative lignin and holocellulose and extractive contents of wood. Cellulose and hemicellulose have a higher heating value of 18.6 kJ kg-1, whereas lignin has a higher heating value of 23.2–25.6 kJ kg-1. Higher heating values of extractives are about 32–37 kJ kg-1.

High Heat Value vs. Low Heat Value - Kuma Stoves

WebThe calorific value of a fuel is usually expressed as Higher Heating Value (HHV) and/or Lower Heating Value (LHV). The difference is caused by the heat of evaporation of the water formed from the hydrogen in the material and the moisture. Note that the difference between the two heating values depends on the chemical composition of the fuel.
