A gas-injection lance, burner, and method for use in a high temperature heating system which provides a non-axisymmetric flow of a reaction-rate enhancing gas in sufficient proximity to the flame of the system, which extends over the surface to be heated, to create an aerodynamically reduced pressure field sufficient to deform the flame and displace it in the direction of the surface to be heated. The present method provides substantially enhanced heating with the virtual elimination of hot spots.

In a method of heating a surface comprising providing a burner system which produces a flame extending over said surface and providing one or more reaction-rate enhancing gas lances between the burner system and the surface, said lances producing a jet of said gas between the flame and the surface,

In a method of heating a surface comprising providing a burner system which produces a flame extending over said surface and providing one or more reaction-rate enhancing gas lances between the burner system and the surface, said lances producing a jet of said gas between the flame and the surface, the improvement comprising emitting said reaction rate enhancing gas such that the point of exit of the gas taken perpendicular to the longitudinal axis of the flow of the gas is essentially non-circular, thereby enhancing the uniformity of heating by producing a jet which creates an aerodynamically reduced pressure field thereby deforming the flame and displacing the flame toward the surface.
