In this work it was made the characterization of distinct ash flows in a biomass thermal power plant using bubbling fluidised bed technology. Bottom bed ashes differ significantly from fly ashes, in concern of both physical characteristics and chemical composition. It was observed a modification in some physical-chemical characteristics of the ashes in result of their exposition to atmospheric air. The pH of the distinct ash samples was alkaline, with values in range 10.3 to...
