Wood pellets
Fuel granules – pellets, are widely used recently, environmentally friendly biofuel, obtained from coniferous wood (spruce, pine) without the addition of chemical components.
Pellets have the following advantages over traditional fuels:
- high bulk density – not less than 600kg/m3;
- calorific value is 4.3-4.5 kW/kg, which is 1.5 times higher than that of wood and comparable to coal;
- design features of furnaces make it possible to automate the process of obtaining the required amount of thermal energy;
- combustion of pellets in the boiler furnace is more efficient – the amount of residues (ash) does not exceed 0.5% of the total volume of used pellets;
- wood pellets are much more environmentally friendly than traditional fuel: 10-50 times lower carbon dioxide emissions into the air, 15-20 times less ash formation than when burning coal.
The granules produced by our company comply with the requirements of STB 2027-2010 and the requirements of European standards EN ISO 17225-2 (DINplus-A1), DIN EN ISO 17225-2 (ENplus-A1).
