INCINERATION OF CFC-12 BY BURNER METHODS

A method of incinerating dichlorodifluoromethane (CFC-12) in the premixed and diffusion flames has been developed. In the case of premixed CFC-12/methane/air flames, the burning velocity decreases with addition of CFC-12, but the amount of unreacted CFC-12 in the burned gas is lower than the detection limit of the gas-chromatograph for molar ratios of CFC-12/melhane smaller than around 0.2 when methane/air ratio is stoichiometric. The degree of destruction of CFC-12 decreases with increase of the CFC-12/methane ratio. No soot formation is observed in the range examined for the premixed flame experiments. On the other hand, in the case of CFC-12/methane diffusion flames in air, a large amount of soot formation is observed, although CFC-12 is also destructed almost completely in the range examined. These results indicate that the incineration method is useful and practical for the destruction of chloro-fluorocarbons. © 1990, Taylor & Francis Group, LLC. All rights reserved.
