Pellets are made by subjecting sawdust, wood waste that is pure (without paint) products from sawmills, woodworking shops and other activities related to woodworking. This type of fuel is eco-assignable because you are not using any type of glue to keep it compact. In fact, the compactness of the pellets over time is guaranteed by a natural substance found in wood: wood. addition to being an environmentally friendly fuel pellets also has the technical advantages. While the normal wood has a calorific value of 4.4 kW / kg (with 15% humidity with 18 months), one of the pellets is 5.3 kW / kg. The density of pellets is 650 kg / M3 and the water content is equal to '8% of its weight. We therefore do not need to be seasoned pellets to obtain a sufficiently adequate heat yield. The diameter ranges from a minimum of 5 mm aun up to 8 mm. To ensure combustion without problems it is necessary that the pellets be stored in a dry place.
In nature there is evidence that wood, when it makes the complete decomposition, the amount of free atmospheric CO ² (carbon dioxide) which is then used for the growth and development of new plants. It 'also proved that an optimal combustion of wood in the free atmosphere, in turn, the CO ² (carbon dioxide) that can contribute to the development and natural growth of plants.
