Treatment following washout recovers most of the ammonium perchlorate from the residue for reuse, desensitizing the washout residue. Often this material is subsequently disposed of through open burning/open detonation (OB/OD) or in landfills.
This paper presents results from a small bed combustor designed to examine materials issues and ash chemistry in a configuration similar to a grate-fired industrial combustion system. Desensitized EM has been mixed with pine biomass fuels and burned in the bed combustor under a variety of combustion conditions. Temperature measurements in the bed and inspection following the combustion event were used to assess the potential for materials damage in a full-scale system. Residual ash samples were analyzed to determine the amount of chlorine retained in the ash. Thermochemical modeling designed to simulate combustion of EM in a waste incinerator was used to predict the major products of combustion. We discuss the significance of these results with respect to previous results and to the plans for a full-scale commercial cofiring test. %8 2002-01-01
