Pellet is composed of small cylinders of the size of 6 – 12 mm, obtained by subjecting the wood sawdust at very high pressure. The pellet is then a totally natural and economical product: these are the reasons why it has become in recent years one of the most widely used biomass. The pellets are packed in bags of 10-15 kg, space saving, that facilitate transportation. In addition to having a high heating capacity, pellet is extremely light, compact and easy to find. The same is used for domestic purposes, but also for industrial ones: in that case it can be stored in large quantities in silos, ensuring autonomy. Unique Tip: keep the pellets away from sources of moisture to ensure better conservation.
Pellet vs Wood
The thermo-chemical and product specifications of pellets far exceed those of wood chips and logs in terms of both quality and uniformity. These include: higher energy content (5.0 kW/Kg compared to 4.4 kW/Kg in wood), lower water content (8% moisture content compared to 50% in wood), and a more even, regular size. These qualities make wood pellets easier to handle and transport, allowing much longer storage periods, with the result that pellets can be commercially distributed over a much wider radius at a more economical price.
Gruppo Ravelli has always been driven by its careful consideration in protecting the environment and the balance of the ecosystem by manufacturing products that will best reconcile the demands of economic development with environmental protection. The company’s action fits into a wider trend towards global and individual rediscovery of ecological applications, in order to guarantee sustainable development dedicated to preserving the very world in which we live today.
Pellet: a revolution in home heating
The diagram illustrates how the pellets are transformed during combustion. Thanks to the combined action of the sun’s energy, carbon dioxide, water and the dissolved mineral salts, the pellets are constantly renewed.
he combustion releases the same amount of CO2 as the quantity absorbed and developed by a tree during the growth and the natural decomposition in a forest. The combustion of pellets, therefore, does not increase the CO2 quantity of the atmosphere.
The other important aspect of the pellet is the content of ash: while wood contains bark and various impurities, a good quality pellet has an ash content less than 1% of the total weight.
