3. What are Wood Pellets?
Wood pellets are made from sawdust and wood shavings. The material used cannot contain any foreign
substance such as glue, varnish or synthetic substances. Subjecting it to high pressure, the wood is
pressed through a plate with holes, and due to the high pressure, the sawdust is heated activating the
natural binders of the wood. Thus, the pellets keep their shape even without the addition of bonding
substances. The density of the wood pellet varies according to the type of wood and can be 1.5 – twice
greater than that of natural wood. The diameter of the cylindrical rods is 6-10 mm and their length can
vary between 10 and 50 mm. Their weight is equal to about 650 kg/m. Due to the low content of water
(approx 8%) they have a high energy content. The standards AS/NZS4014.6 de ne the quality of the
pellets:
Do not put the bag of pellets on the cast parts during the loading operations.
The pellets must be transported and stored in a dry place. They swell on contact with any moisture
and cannot be used. They must always be protected from moisutre, both during transport and in
storage. Ravelli recommends using a pellet with a diameter of 6 mm for the stove.
