Pellet fuel (or pellets) is a fuel obtained from the selected, dried and then compressed sawdust in the form of small cylinders with a diameter of a few millimeters, typically 6 mm.
The pellets are small cylinders of pressed wood, produced from residues of sawdust and woodworking (chips and sawdust), generally produced by sawmills and joinery.
The raw material is selected in advance, dried and cleaned from impurities, to obtain a constant quality, with a well-defined residual humidity (about 10%); the preparation also includes a selection of more tender wood flours (firs, conifers) and a certain qualitative and dimensional homogeneity; the greater accuracy of this preparation translates into better product quality.
The pellet is used as fuel for the latest generation of stoves, replacing firewood in industrial plants, plants, municipal heating systems, industrial companies and domestic environments. This entails a series of ecological, energy and heating system management improvements compared to traditional stoves.
Pellets are a convenient handy fuel that not only is CO2-neutral and that generates heat in an eco-friendly way, but it is also a competitive alternative to fuel oil or gas. This ecological and clean heating has also an high economic attractiveness. Moreover the EN plus certification guarantees a high heat value. A tonne of pellets is equal to the calorific value of roughly 500 litres of heating oil.
High combustion efficiency
During the combustion of wood pellets little ash is formed in relation to other solid fuels such as coal.
The most innovative pellets, with the addition of combustion modifiers, also limit the amount of soot produced therefore the use of pellet boilers becomes practically maintenance-free, ensuring a low frequency of boiler cleaning and a longer plant life.
Pellets are produced out of renewable raw material and show an excellent energy balance. The production of pellets requires only a fraction of energy that is accumulated in the pellets as the energy necessary to dry is covered mostly by the residual heat of wood thermal power stations, mainly lighted with bark coming from the saw mills. Therefore the production of wood pellets is considered almost CO2-neutral.
Wood pellets are one of the cleanest renewable fuels in the world.
Pellets only produce the amount of CO2 that is absorbed by the atmosphere during tree growth.
Careful use of the precious wood raw material and the origin of wood from sustainably managed forests are particularly important.
Heating with pellets is a valid contribution to climate protection and the fight against the greenhouse effect.
