ABSTRACT:
A method and an incinerator in which halogenated organic compounds are burned in the presence of oxygen or oxygen enriched air to produce combustion products. The 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 firing a burner, burning a hydrogen containing fuel at a fuel-rich stoichiometry, into the combustion products so that the fuel will react with the unreacted oxygen. This will reduce 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.
