The authors have numerically modeled the breakdown of small quantities of several chlorinated hydrocarbons (CH{sub 3}Cl, CH{sub 2}Cl{sub 2}, CHCl{sub 3}, CCl{sub 4}, C{sub 2}H{sub 3}Cl, and C{sub 2}H{sub 5}Cl) in a lean mixture of combustion products between 800 and 1,480 K. This simulates the fate of poorly atomized waste in a liquid-injection incinerator. Kinetics calculations were performed using the CHEMKIN and SENKIN programs, with a reaction mechanism that was developed at Louisiana State University to model flat-flame burner experiments. A 99.99-percent destruction efficiency was attained in one second at temperatures ranging from 1,280 to 960 k, with CCl{sub 4} requiring the highest temperature for destruction and C{sub 2}H{sub 5}Cl the lowest. For all compounds except C{sub 2}H{sub 5}Cl, there was a range of temperatures at which byproducts accounted for several percent of the elemental chlorine at the outlet. The more heavily chlorinated compounds formed more byproducts even though the amount of elemental chlorine was the same in all cases. The sensitivity of results to residence time, equivalence ratio, temperature profile, and the presence of additional chlorine, was examined for the case of CHCl{sub 3}.
