Halogenated organic compounds are burned in the presence of oxygen or oxygen-enriched air in incinerator 26 to produce gaseous combustion products. The gaseous combustion products potentially include unreacted oxygen and halogenated organic compounds which can react with oxygen to produce halogenated furans and dioxins. The formation of the halogenated furans and dioxins is minimized by operating burners 42 and 44 to burn a hydrogen containing fuel at a fuel-rich stoichiometry, in the presence of the combustion products so that the fuel reacts with the unreacted oxygen. This further combustion reduces formation of the halogenated furans and dioxins. Any of the halogenated furans and dioxins that are formed are substantially eliminated by the reaction of hydrogen supplied by the fuel with the halogenated furans and dioxins. <IMAGE> |
