average a well-seasoned wood has a calorific value of 3200 kcal/kg.
Calorific value of wood based on its humidity level:
The
CALORIFIC VALUE
of the wood is the amount of heat yielded
during combustion, referring to the unit quantity of the material
burned.
The calorific value of a wood type depends on the presence of
lignin
(6000 Kcal/Kg), or
cellulose
(4000 Kcal/Kg) as well as the
amount of
resin
(8500 Kcal/Kg).
The calorific value per unit of weight ( = absolute) is highest in
Conifers
Absolute calorific value of conifers: 4700 Kcal/Kg
Absolute calorific value of broad-leaved species: 4350
Kcal/Kg.
On the other hand the
SPECIFIC WEIGHT
of the
“broad-leaved
species” is greater; therefore with equal volumes introduced into the
heating cooker/heating stove, both the weight and amount of heat
available for combustion are greater; in practice the relative calorific
value is higher (referring to a unit of volume).
Example:
the calorific value of the white fir is practically the same
as that of the oak, but the oak has a specific weight that is twice
that of the fir. Therefore half the volume of oak must be introduced
into the heating cooker/heating stove in order to have the same
"heat" obtained from the fir.
