Presently the feeding systems of polydispersed biomass are composed by a silo, which has at its bottom an endless screw or a transportation band. Typically polyspersed biomass is characterised by the presence of matter linking between fibbers, cohesive biomass powder and finally a bread granulometric distribution. These properties are the cause of archs or bridges occurrence formed inside the silo, specifically at its convergent section, which hinder the down movement of the stored material. This paper deals with an alternative feeding system, based on the study of the properties of polydispersed biomass, which is expected to allow a free flow of the biomass in the silo. The proposed system is basically composed of a negative wall silo having removing and scratching devices as well as an endless screw and reductor. In this new design, the final convergent section of the silo is suppressed.
