Effect of leaching on the ash behavior of wheat straw and olive residue during fluidized bed combustion

Fluidized bed combustion has been proven to be an attractive method for the conversion of agroresidues to energy offering economical and environmental benefits. The low melting point ash of agroresidues cause a number of prob lems e.g., sintering, agglomeration, deposition, etc,, which consist the ma in obstacles for economical and viable application of this conversion metho d. Leaching that is considered to be a low cost pretreatment technique for the elimination of ash related problems in biomass boilers studied here. Th e produced results clearly demonstrate that leaching could help significant ly to reduce the ash related problems caused during the operation of fluidi zed bed combustors with biomass.
