Incineration represents a viable method for the safe destruction of chlorinated hydrocarbons (CHC). Consequently, understanding the combustion characteristics of chlorinated hydrocarbons and the effects of CHCs on the combustion chemistry of hydrocarbons calls for investigations with regard to the nature of potentially toxic intermediates that may form during incineration for the continued safe utilization of this important technology. Temperature and species mole fraction profiles were obtained for atmospheric-pressure, premixed, laminar, flat flames of CCl[sub 4]/CH[sub 4] mixtures under both fuel-lean and fuel-rich conditions. Mole fraction profiles were determined using microprobe sampling coupled to on-line gas chromatography/mass spectrometry for the reactants and for CO, CO[sub 2], HCl, H[sub 2]O, COCl[sub 2], CH[sub 3]Cl, CH[sub 2]Cl[sub 2], CHCl[sub 3], CCl[sub 4], C[sub 2]H[sub 3]Cl, 1.1-C[sub 2]H[sub 2]Cl[sub 2], 1,2-C[sub 2]H[sub 2]Cl[sub 2], C[sub 2]HCl[sub 3], 1,1,1,2-C[sub 2]H[sub 2]Cl[sub 4], C[sub 2]Cl[sub 4], C[sub 2]Cl[sub 6], C[sub 2]H[sub 2], C[sub 2]H[sub 4], C[sub 2]H[sub 6], C[sub 4]H[sub 4], C[sub 4]H[sub 2], C[sub 6]H[sub 6], and C[sub 6]H[sub 5]Cl. The role of these species, in view of the current understanding of the mechanism of combustion of CCl[sub 4] and CH[sub 4], was discussed.
