Abstract |
The paper gives results of bench-scale tests to characterize combustion emissions from chlorofluorocarbon (CFC-11 and -12) incineration. The destruction efficiencies (DEs) of the CFCs and the major products of incomplete combustion (PICs) from each CFC were determined. DEs of at least 99.999% can be attained repeatedly for both CFCs. Major PICs identified were non-halogenated: toluene and xylene were found most frequently. PIC concentrations were independent of the CFC concentration in the fuel. Sampling was performed one time to screen for polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/PCDF) and polyaromatic hydrocarbons (PAHs) while incinerating CFC-12. Even with a DE of greater than 99.999%, high levels of PCDD/PCDF were formed. The extensive PCDD/PCDF formation apparently occurred in the absence of entrained particulate matter. |
