The report gives results of the collection of combustion emission characterization data from chlorofluorocarbon (CFC) incineration. A bench scale test program to provide emission characterization data from CFC incineration was developed and performed, with emphasis on the formation of products of incomplete combustion (PICs). Tests involved separate metering of CFC-11 and -12 into a propane gas primary flame. Propane also fueled an afterburner. Simultaneous combustion gas samples were taken upstream and downstream of the afterburner. The gas samples were analyzed for the CFCs to determine the destruction efficiencies of the CFCs and for the major PICs from each CFC. Sampling was performed on time to screen for polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and polycyclic aromatic hydrocarbons (PAHs) while incinerating CFC-12. Toluene and xylene were the two most frequently occurring PICs in the study. Most of the PICs identified were non-halogenated. PIC concentrations were independent of the concentration of CFC in the fuel. Flammability limits were 39 volume % CFC-11 and 58 volume % CFC-12 in propane. Destruction efficiencies of at least 99.999% can be repeatedly attained for both CFC-11 and -12 even from relatively low temperature flames.
