Manual For Bio-fuels
The wood fuels can be classified by the
origin of raw material as
fuels from the forest or short rotation forest,
and recovered wood.
While fuels from the forest and energy
forest can be considered environmentally
friendly, the recovered wood fuels surely cannot.
Calorific value
The calorific value is the amount of heat

The higher or gross calorific value and lower or
net calorific value (qgr and qnet ,respectively)
can be found via the calorific
value measured in the bomb calorimeter.
