the regulations in force in the country of installation
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.
•
Content: 100% untreated wood with no added binding agents (max percentage of bark: 5%).
•
Packaging: in bags made from environmentally friendly or biologically decomposable material.
The company strongly recommends using certified fuel for its products (DINplus, Ö-Norm M7135 or Pellet Gold).
Poor quality pellets or others that do not comply with that specified previously compromises the operation of your
product and can therefore render the warranty and product liability null and void.
