Wood pellets are the most quality type of granular fuel. This cylindrical compressed wood waste (sawdust, chips and other waste sawmill and wood processing). At burning 1 ton of pellets is allocated as much energy as in the burning: Pellets are environmentally friendly fuel, since their combustion emit as much CO2 as was absorbed by the tree during its growth (the closed carbon exchange), unlike coal etc. Using the pellets, you save from cutting the living forest and pollution waste wood processing of environment. ADVANTAGES WOOD PELLETS: -high caloric value; - Transportation of pellets, does not require specialized transport. Pellets are easy to store. Convenient packaging allows to calculate the volume of transport and consumption of pellets. USE OF PELLETS: If the pellets are stored in sealed plastic bags, their quality is not reduced. |
