5.1 PELLETS
Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the processing
of natural dried wood (without paints). The compactness of the material is guaranteed by the lignin contained
in the wood itself and allows pellets to be produced without glue or binders.
The market offers different types of pellets with characteristics that vary according to the wood mixtures used.
The diameter varies between 6 and 8 mm, with a standard length ranging from 5 to 30 mm. Good quality pellets
have a density that varies between 600 and over 750 kg/m3, with a moisture content that ranges from 5% to 8%
of its weight.
Pellets have technical advantages besides being an ecological fuel, as the wood residue is used completely,
thereby achieving cleaner combustion than that of fossil fuels.
Good-quality wood has a calorific value of 4.4 kW/kg (15% moisture, after about 18 months of seasoning),
whereas that of pellets is 4.9 kW/kg. To ensure good combustion, the pellets must be stored in a dry place and
protected from dirt. Pellets are usually supplied in 15 kg bags, therefore, storing them is very convenient.
Good quality pellets guarantee good combustion, thereby decreasing harmful emissions into the atmosphere.

The poorer the quality of the fuel, the more often the internal parts of the brazier and
combustion chamber must be cleaned.
DINplus, Ö-Norm M7135 and Pellet gold are examples of the major quality certifications of pellets in the European
market and guarantee that the following are complied with:
• calorific value: 4.9 kWh/kg.
• Water content: max 10% of the weight.
• Percentage of ash: max 0.5% of the weight.
• Diameter: 5 – 6 mm.
• Length: max 30 mm.
