Chapter 3
WHAT IS THE PELLET?
Pellets are realised by subjecting wood shavings i.e. the rejects of pure wood (without paint) sawmill,
carpenter products and products from other activities connected to working and transforming wood, to
very high pressures.
This type of fuel is absolutely ecological as no glues are used to hold it together. In fact, the compactness
of the pellets is guaranteed through time by a natural substance that is found in wood: lignin.
As well as being an ecological fuel, as wood residues are made the most of, the pellet also has technical
advantages.
Pellet density is about 650 kg/m3 and water content is equal to 8% of its weight. For this reason the pellet
does not have to be seasoned in order to obtain a suffi
ciently adequate heat yield.
The pellet used must comply with the features described by the Standard:
Ö-Norm M 7135
™
DIN plus 51731
™
UNI CEN/TS 14961
™
Extrafl ame recommends the use of pellets with a diameter of 6 mm with its products.
