A combustion method and burner nozzle system having a DeNOx Stabilizer concentrically secured within a burner nozzle such that the fuel stream is separated into an outer fuel-rich stream and an inner fuel-lean stream. The outer fuel-rich stream passes around the exterior of the DeNOx Stabilizer where its flow area is increased thereby decreasing its velocity before it is discharged from the burner nozzle. Concurrently, the inner fuel-lean stream passes through the DeNOx Stabilizer where its flow area is reduced thereby increasing its velocity before this stream is discharged from the burner nozzle central to the slower fuel-rich stream. Mixing members interior of the burner nozzle further mix the fuel-rich stream before exiting the nozzle.

A burner nozzle comprising: an outer elongated tubular housing secured downstream of a burner elbow and having a fuel entrance and a fuel exit; an inner elongated tubular member concentrically secured within said housing having upstream and downstream openings; mixing members intermediate said inner member and said outer housing; whereby conbustible fuel passing through said elbow and into said housing is divided into an outer fuel-rich stream and an inner fuel-lean stream with said outer fuel-rich stream passing around said inner tubular member and being mixed by said mixing members before exiting said housing in a generally cylindrical stream, and with said inner fuel-lean stream passing through said inner tubular member before exiting said housing in a central region of said outer fuel-rich stream.
