Today biofuel is becoming more and more popular type of alternative fuel, gradually substituting coal, diesel and electricity in the sphere of heating industrial buildings and private homes.
Pellets and fuel bricks are produced from different types of agricultural and woodwork waste including wood dust, sunflower husk, bulrush, agricultural waste, thatch, linen and a lot of other waste.
The basic method of bio-fuel production is pressing by high temperatures (Pini-Key brick comes as a result) as well as pressing by means of applied hydraulic effort (as a result a RUF brick is created).
The whole process of bio-fuel production can be divided into the following stages:
- Raw materials chopping. To produce fuel bricks raw material of fine fraction is required, thus some types of waste should be primarily chopped. For example. Sunflower husk can be used for pressing right away, but woodwork waste, bark or chipped wood should be chopped in special chopping machines.
- Raw material drying. The pellets and bricks quality as well as equipment productivity depend on the dampness of the incoming material. The optimum dampness is dampness that does not exceed 12% if bricks are made by hydraulic method – no more that 18% for pellets – less than 18%http://localhost/fora-zapad.ru/www/ If dampness indicators exceed the norm, the material is not pelleted and bricked, thus the drying stage can be skipped only if a very dry waste is used, e.g. sunflower husk or furniture waste.
- Pelleting or Pressing – i.e. direct production of pellets and bricks on special equipment (pelleters and presses consequently).
It should be remembered that if you want to produce "Pini_Key” bricks, raw materials that cannot be pressed because of small number of lignin such as aspen, birch, distillery waste or rotten wood. However, such waste can be used in bricks production by means of hydraulic method.
"Fora-Zapad” company produces equipment for all stages of bio-fuel production: drying, chopping, and both types of pressing.
