ABSTRACT:
An incineration process which can utilize any type of incineration means for disposing of hazardous, as well as non-hazardous, burnable waste. Such waste include toxic combustible liquids, oil slurries, soils contaminated with dioxin, PCBs, creosote, or any other potentially toxic combustible material. In particular, the present invention relates to an incineration process which has no continuous stack discharge of polutants. In this process, the flue gas stream from the incineration stages is enriched with oxygen and fed to a downstream combustion zone. A portion of the flue gas stream from the downstream combustion zone is enriched with oxygen and recycled to the incineration means. The remaining portion of the flue gas stream from the downstream combustion zone is scrubbed to remove acid gases and passed through a purification zone wherein any remaining contaminates are removed.
