Description:
The paper discusses experiments that were performed in a 73-kW pilot-scale rotary-kiln incinerator simulator equipped with a 73-kW secondary combustion chamber during which a complex organic mixture containing bromine (Br) and chlorine (Cl) was incinerated. Detailed measurements of products of incomplete combustion (PICs) were made, including volatile and semi-volatile organics as well as polychlorinated and polybrominated dibenzo-p-dioxins and dibenzo furans (PCDDs/PCDFs and PBDDs/PBDFs) and mixed bromochloro dioxins and furans (PBCDDs/PBCDFs). Results indicated that the ratio of some analogous brominated to chlorinated PICs were greater than the ratios of the amount of Br to Cl in the feed stream. Of particular importance is the potential for this phenomenon to confound the measurement of emissions of total polyhalogenated dibenzo dioxins/furans by promoting formation of PBDDs/PBDFs and PBCDDs/PBCDFs (compounds that are typically not included in regulatory or risk-assessment calculations) at the expense of PCDDs/PCDFs.
