Abstract
A gas turbine systems of reducing NOX emissions and enhancing operability comprises a compressor; a combustor disposed downstream of and in fluid communication with the compressor; a turbine assembly disposed down stream of and in fluid communication with the combustor; an oxygen-enriched gas source disposed in selective fluid communication with the compressor, the combustor, or a combination of the foregoing, wherein the oxygen-enriched gas source is a pressure swing absorption system, an electrolyzer, or a membrane reactor.
Claims2
A gas turbine system, comprising:
- a compressor;
- a combustor disposed downstream of and directly in fluid communication with the compressor;
- a turbine assembly disposed downstream of and in fluid communication with the combustor;
- and an oxygen-enriched gas source disposed in selective fluid communication with the compressor and the combustor, via at least one oxygen-enriched gas stream disposed in fluid communication with the oxygen-enriched gas source, the at least one oxygen-enriched gas stream further disposed in selectively direct fluid communication with the compressor and selectively direct fluid communication with the combustor, wherein the oxygen-enriched gas source is a pressure swing absorption system, an electrolyzer, or a membrane reactor.
