However, the benefits resulting from improvements in the long run, justify the costs incurred. Biofuel of the future should be processed in some way to achieve an acceptable economic returns through the automation of thermal plants. Automation can be accomplished only if sufficient fuel homogeneous, so could be made fuel delivery system at an acceptable cost and reliability. One important aspect in this regard is to reduce the use of human factors as possible. Economic rivals of biofuels is mainly fuel oil and natural gas. Fuel oil and gas can be easily adapted to automation, since the pipes are transported easily.
For achieve the same ease of transportation, biofuels should be processed into pellets. Another important reason for biomass – is, of course, higher heating value (calorific value) and ease of operation the combustion process. Pellets and briquettes – a deeply revised and ecologically perfect fuel. Often referred to as 'dry fuel', as humidity decreases to 10%. Pellets and briquettes are used more or less the same types of thermal plants.
The advantage of using compressed biofuels is the cost of equipment for boiler plants with capacity up to 2 MW, which require less investment pellets and briquettes in comparison with the facilities for wood chips. Storage capacity for wood chips is much greater and therefore more expensive construction of a warehouse, and because the pellets / briquettes are compressed to a smaller volume at the same energy, the amount of storage for them can be reduced to 50%. Pellets can be stored closer to residential areas, since this material is 'dead' after passing through heat treatment. It has the advantage of compared with fresh wood chips, which contain spores that are prone to spontaneous combustion when the internal temperature increases, and thus cause an allergic reaction in people who come in contact with her. Wood chips can contain parasites that naturally hygienic with respect to the people who live nearby.
