KAOLIN ADDED TO BIOMASS FUELS FOR MITIGATION OF ASHES AGGLOMERATION

Abstract

Biomass fuels have been contributing a major part to renewable energy. However, combustions of biomass fuels causes the serious effect of soot deposition in furnace systems. In this work, biomass fuels from sugarcane-bagasse, rice-husk and coffee-husk were added with fine powder of kaolin oral to mitigate the ashes agglomeration and fusibility. The fuel pellet samples obtained from the biosmass sources were added with the kaolin-based additive at weight concentrations of 0, 2, 4 and 8 wt.%. Approximate and ultimate analyses of the fuel pellets were evaluated. The effect on mitigating the agglomeration and fusibility of the kaolin additive in the biomass fuel pellets was evaluated when burned at 1100oC
