Information.

Description:

The report gives results of experiments to determine the effect of flame zone temperature on gas-phase flame formation and destruction of products of incomplete combustion (PICS) during dichlorodi-fluoromethane (CFC-12) incineration. The effect of water injection into the flame zone was also studied. Tests involved burning CFC-12 in a propane gas flame. Combustion gas samples were taken and analyzed for volatile organic compounds as well as polychlorinated dibenzo-p-dioxin and dibenzofuran (PCDD/PCDF). CDD/PCDF were not detected at baseline operating conditions (1204 C and 9.3% CFC-12 by volume in fuel). Low levels of PCDD/ PCDF were detected in the combustion gas at a lower temperature (913 C). Poor combustion conditions producing smoke and soot may have contributed to the formation of PCDD/PCDF. Low levels of PCC/PCDF were also detected at the lower temperature with water injection into the flame zone. lame zone water injection may have a reducing effect on PCDD/PCDF formation during CFC-12 incineration. alogenated PICs (including chloromethane, vinyl chloride, CFC-11, dichloroethane, chloroform, trichloroethane, chlorobenzene, dichloropropene, carbon tetrachloride, methylene chloride, and tetrachloroethane) were detected during CFC-12 incineration.
