An oxy-fuel burner arrangement having a first conduit having a nozzle aperture with an aspect ratio, D1/D2, of greater than or equal to about 2.0. The first conduit is arranged and disposed to provide a first fluid stream, where the first fluid stream is a combustible fuel. The burner arrangement further includes at least one second conduit arranged and disposed to provide a second gas stream circumferentially around the first fluid stream, where the second gas stream includes oxygen. A precombustor is arranged and disposed to receive the first fluid stream and second gas stream where an oxy-fuel flame is produced. The geometry of the nozzle aperture and the cross-sectional geometry of the first conduit are dissimilar.

Oxy-fuel burner arrangement

Method and apparatus for reducing NOX production in an air-oxygen-fuel combustion process by creating post mix oxy-fuel flame and introducing air around said oxy-fuel flame at an angle of greater than 0.degree. to 90.degree. to the longitudinal axis of the oxy-fuel flame.
