Petersburg, or in a traditional wood-processing areas (Kirov, Vologda, r.Mari E, etc.). Except this, there are small producers (docks) located in major cities like Moscow or Novosibirsk, but the production of pellets in this case is not the focus of their activities. Common count of existing enterprises is not more than fifty, and remains almost constant, despite the construction of new plants, some of the existing closed due to financial or production problems. Characteristics of pellet size pellets are typically 6-8 mm in diameter and 5-70 mm long, depending on the quality of raw materials and the production of pellets, although it should be noted, there are pellets and other dimensions, such as Novosibirsk produce pellets with a diameter of 10 mm. Raw material for pellet production in our country are conifers, however, the best raw material pellets obtained from hardwood (this requires a higher grade equipment). Humidity 7-10% pellet, which allows them to good use in the gasification boilers (albeit after a slight revision of the latter). Pellet density of 1.5, so the pellets sink in water. The calorific value of 1 kg pellets = 5 kW * hour (although there do not forget about the efficiency of the device where you burn them, and in reality this figure is less), which is approximately 1.5 times greater than that of wood. Enough about, but quite literally possible to say that the content energy in one kilogram of pellets is equal to the energy contained in half a liter of liquid fuels.
