Design and testing functional model compacting machine for produce new shape biofuels

Abstract

© Published under licence by IOP Publishing Ltd. Compaction technologies have been known for over 130 years. Among the best-known compaction technologies are included briquetting, pelleting and compacting. The end products of such technologies are briquettes, pellets and granules. Recent times have seen a worldwide "boom" in the use of these refinings, especially with regard to pellets. One great advantage of pellets in comparison with classic fuels is that according to need the three decisive parameters ' shape, size and density ' of the resultant fuel can be changed during production. This leads to an optimization of costs for their production and storage and transportation requirements, but most of all, prerequisites in terms of optimal energy recovery. One of the most discussed issues in the production of refined biofuels is the shape and size of the refined fuel. The quadrangle, n-angle or cylinder do not have optimal shapes from the point of view of automated transport in the fuel combustion process. From this standpoint the ball is the optimal shape, but it is not possible to create such pressings in a continuous process and present-day pressing and compacting machines lack a "fuel life" phase under pressure with simultaneous cooling. The endurance and cooling process has of course a great influence on the stability of the fuel produced. The goal of the submitted paper is the development, design and testing of a new, patent-protected compacting machine construction which will allow the production of pressings biofuels of an almost circular shape. In contrast with readily available compacting - compression machines, such a compactor also provides cooling of the pressings under high pressure.
