Abstract:
A method for producing hot combustion waste gas, comprising the steps of:producing a hot combustion waste gas by combustion in a burner, wherein the combustion in the burner is one or more of catalytically initiated and catalytically stabilized; feeding a first portion of the combustion waste gas to a first inlet of a first oxygen separation device; feeding an oxygen-containing gas to a second inlet of the first oxygen separation device; removing oxygen from the oxygen-containing gas by an oxygen separation means of the first oxygen separation device, wherein the step of removing oxygen reduces an oxygen content of the oxygen-containing gas; feeding said oxygen to the first portion of the combustion waste gas, wherein the step of feeding said oxygen enriches an oxygen content of the first portion of the combustion waste gas; and, feeding the oxygen-enriched, first portion of the combustion waste gas and a fuel or a fuel/steam mixture to the burner to form a combustion mixture that burns in the burner in the step of producing the hot combustion waste gas.
