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.
Wood Energy - List and values of wood fuel parameters - Part 1
The effect of moisture content on the heating value of wood is clearly defined in Figure 1. Figure 1: The effect of moisture content on the heating value of wood (kWh/kg) It is thus obvious that the acquisition of energy per M3 of wood fuel increases as the dry matter content per M3 increases and the moisture content decreases.
