Pellets are made by applying very high
pressure to sawdust; i.e. the residue of
raw timber (without paint) produced by
sawmills, carpentry works and other
activities involved in processing wood.
This type of fuel is completely
environmentally friendly, as no binders of
any kind are used to keep it compact. In
fact, the compactness of the pellets over
time is guaranteed by lignite, a natural
substance found in the wood itself.
As we
ll as being an environmentally
friendly fuel, since wood residues are
exploited to the maximum, pellets also
have technical advantages.
While the heating power of wood is 4.4
kg (with 15% humidity, after about
18 months seasoning), the power of
pellets is 5.3 kW/kg.
The density of the pellet is 650kg/m
3
the water content is 8% of its weight.
For this reason, pellets do not need to be
seasoned to obtain a sufficient heating
Pellet diameters range from a minimum
of 5 mm to a maximum of 8 mm, tho
Extraflame recommends using 6 mm
pellets.
3.1 Pellet storage
To guarantee problem-
pellets must be stored in a dry place.
