An industrial gas burner especially suitable for operation with oxygen-enriched combustion air is constructed and arranged to discharge concentric and complementary spinning streams of gas and oxygen-enriched combustion air acting to create a recirculation and intermixing zone spaced outwardly from the burner mouth to provide aerodynamic flame stabilization in space. The burner flame is thus outwardly removed from and out of contact with the burner, thereby avoiding excessive heating of the burner. |
