Incineration of hazardous waste has proven to be a successful engineering and environmental solution to the problems of hazardous waste disposal. Since much of the hazardous waste burned in incinerators contains chlorine, a large amount of study has been focused on modeling the chemical kinetics of flames with chlorinated fuels and chlorinated fuels co-fired with methane. A 244-reaction mechanism containing 60 species was used with the PREMIX computer program to model a stoichiometric carbon tetrachloride-methane-air flat flame with a Cl/H ratio of 0.33. The flame was found to progress in three stages, an initiation stage, a chlorine inhibited oxidation stage, and a CO burnout stage. Some important reactions occurring in each stage were identified. The simulation showed that a lack of CH{sub 3} radicals inhibited the highly exothermic oxidation reaction O + CH{sub 3} = CH{sub 2}O + H. As a result, the less energetic oxidation of acetylene, O + C{sub 2}H{sub 2} = CH{sub 2} + CO, became the dominant oxidation reaction. CO burnout was found to begin when hydroxyl radicals became available through the reactions O + HCl = OH + Cl and O + H{sub 2}O = OH + OH.
