Beschreibung
Zusammenfassung:	This invention proposes innovative techniques of NOx reduction in boiler operation through an adaptation of staged combustion in combustion boilers. In preferred processes, air is fed into an air separation unit, and a nitrogen-enriched stream is combined with air to produce a nitrogen-enriched first stage air stream, and at least a portion of an oxygen-enriched stream is mixed with air to produce an oxygen-enriched second stage air stream. A reduction in NOx and increase in efficiency is promoted by the inventive processes and systems.
