Pellets (pellets, pellets, pellets) heating the product belongs to the group of biofuels in which the energy obtained from the combustion of renewable raw materials subjected to granulation.
- The most common form of this fuel is wood pellet - formed from compressing sawdust, which arise when working sawmill and other activities related to the machining of wood products. Wood used in the production of pellets can be both deciduous and coniferous - there are also more exotic compounds derived from palm wood, coconut shells or even logs and branches lying loose. Pelletyzowana may even be an ordinary green grass, creating a frog pellets.
- Wood pellets are manufactured by compressing sawdust, which is obtained as a material Transition in sawmills and other wood processing areas. A pulp is forced through die holes to form granules having a diameter of most frequently 6-8 mm (depending on the size of the holes). Friction causes the material greatly heats up to 70 ° C, so soon after leaving the press, the pellets are cooled in a special cooler. The next step is the packing, standard bags, BigBags with a capacity of approx. 1000 kg or less, for example. 15 kg.
