Circulating-bed combustors (CBC) have been proposed as a potential technology for destroying hazardous wastes. CBCs are normally operated at relatively low temperatures (750 to 900/sup 0/C) compared to typical waste incinerators (1000/sup 0/C or greater) prompting concern for the completeness of destruction of hazardous compounds (POHC) and the formation of products of incomplete combustion (PIC). Tests of the destruction of a mixture of simulated hazardous waste in a pilot-scale CBC were undertaken. Measurements of POHCs and PICs under nonoptimum combustion conditions indicated that the penetration of the POHCs was generally less than 1 x 10/sup -4/ whereas penetration of chlorinated organic PICs normalized with chlorine input was greater than 1 x 10/sup -4/. Correlation of PIC formation with normalized unburned hydrocarbon or CO was high. This observation supports the potential utility of these conventional combustion parameters for continuous monitoring of waste incinerator efficiency in CBCs.
