Ash Behaviour during Combustion of Agropellets Produced by an Agro-Industry—Part 1: Blends Design and Experimental Tests Results

Agropellets are presented as a suitable product to be produced in certain agro-industries which could become Integrated Biomass Logistic Centres (IBLC) by taking advantage of its current resources during those periods their facilities underused. Wheat straw and maize stalk were selected blended with forestry wood an agro-industry dedicated animal feed production. The materials characterized assess the quality input material. Taking into account former, different pellets (blends woody herbaceous biomass) tested fixed bed reactor order study combustion behaviour. Additionally, several predictive indexes also calculated sintering deposition occurrence probability. Ash degree was found directly related composition highly dependent on Si content. Moreover, increase content blend did not proportionally imply higher final blend, would expected. Regarding deposition, due high number factors involved this phenomenon, it has been possible draw clear conclusions. To do this, necessary delve mechanisms, is addressed second part paper. Thus, despite appearance phenomena, behaviour satisfactory test carried out. demonstrated that can act IBLCs, producing pellet for energy market aligns standard ISO 17225-6.
