Pellets or wood pellets – are products of cylindrical shape by extrusion pressed from the dried, pre-milled, vegetable raw materials. Designed to generate heat by burning. Pellets (pellets) – this is a deeply revised and environmentally friendly fuel. The advantage of using biofuels is pressed, first, the majority calorific value compared with chips and lump of wood waste. Secondly, lower cost equipment for boiler plants with capacity of up to 2 megawatts, compared with Auto wood waste. Volume of the warehouse for storage of wood pellets can be reduced at least 50%, compared with the treasure for wood chips. Pellets can be stored in close proximity to residential premises (basement or utility room), since this material is biologically inactive, because was heat-treated.
It is less prone to spontaneous ignition, as it contains dust and spores, which can also cause allergic reactions in humans. According to its characteristics of the fuel pellets are competing with natural gas, but on environmental indicators, they are ahead of all other types of fuels to the same extent as in affordable. production of pellets in the world Relevance of pellets shows an increase the use of wood and agricultural waste in the industrial production of thermal energy in Europe, Scandinavia and North America by 15% annually. Pellets are a real alternative to the Stone Coal and oil, because of its calorific characteristics to the coal, and their environmental parameters at all apart from the competition. If we consider the current trends, it is only in Europe at the beginning of 2003 there were about 200 producers of granular and patch fuel.
