Biofuels are alternative energy sources. However, such sources include any that are not derived from the classic fossil hydrocarbons; natural gas and oil. In fact, even the wood that humanity has been using for centuries to generate heat is an alternative in this classification.
Alternative energy sources are environmentally friendly and renewable and in some cases infinite, such as solar energy or the energy of the movement of air masses. Biofuels are renewable and clean energy sources. It is a product of biological origin, solid, liquid or gaseous. Production and use of biofuel on the basis of own economy allows to receive autonomy from purchased power sources, and at the same time and to solve a problem of utilization of various organic waste, beginning from contents of a cesspool and finishing with the weeds removed from beds.
Production of fuel pellets
Pellets, fuel pellets, as well as fuel briquettes, are made of sawdust, other wood waste, sunflower husks, straw. The plant mass is placed in the bio-plant, that is, the container where the grinding takes place. Get the flour from the waste of vegetable production. This mass enters the dryer, where the liquid is evaporated. It is this process that prepares the mass for high-quality pressing.
In the press-granulator during compression of vegetable flour increases the temperature of the mass. The plant particles contain lignin, similar in composition to the resin. It melts and glues the dried particles of plants; granules of that size which is set at the adjustment of the equipment turn out.
Production of fuel briquettes
The Technology of production of fuel briquettes in many respects resembles the production of pellets. The difference in the shape of the finished product. Agricultural and woodworking waste is also finely chopped and pressed at high pressure.
Some types of raw materials for the production of briquettes must be heated to very high temperature up to 350 degrees. There is a lot of lignin in the wood raw material, so the pressing is excellent. When using annual plants lignin is not enough, so the production of fuel briquettes from straw is with the addition of binders.
At high temperature, the surface of the briquettes is most melted, which makes them durable. This is very important, as transportation can significantly injure biofuels.
