A burner and method is disclosed in which a first oxidizing gas containing a high oxygen concentration is injected as a stream into the central zone of combustion tunnel, and part of the fuel is injected into said central pyrolysis zone to mix with said first oxidizing gas to create a highly luminous, high temperature flame core containing microparticles of carbon of the proper size for maximum luminosity and high temperature, and a relatively small amount of hydrocarbon radicals. In addition, the remaining part of the fuel is injected in a plurality of streams about said flame core to mix with a second oxidizing gas containing a lower oxygen concentration than the first oxidizing gas and injecting said second oxidizing mixture about said flame core and said remaining fuel flow to mix with said remaining fuel flow. This creates a plurality of fuel lean flames which are directed toward said luminous flame core to form a final flame pattern having high temperature, high luminosity and low NOx content.

A method of combusting combustible material in a burner having a combustion tunnel with an outlet opening to generate a high temperature, high luminosity flame, comprising the steps of: separately supplying combustible material, a first oxidizing gas having a given oxygen concentration, and a second oxidizing gas having a different oxygen concentration from said first oxidizing gas to the burner; separately directing said first oxidizing gas and a first portion of said combustible material into said combustion tunnel such that said portion of said combustible material and said first oxidizing gas mix at least partially within said combustion tunnel to create a hot oxygen lean luminous flame core; separately directing the remainder of said combustible material and said second oxidizing gas into said combustion tunnel such that said remainder of said combustible material and said second oxidizing gas mix at least partially within said combustion tunnel to create at least one oxygen rich mixture stream; and mixing said oxygen lean flame core with said at least one oxygen rich mixture stream to create a final highly luminous flame pattern extending out of said combustion tunnel. A burner for combustion of combustible material to generate a high temperature, high luminosity flame which comprises: a combustion tunnel having an outlet opening; means for separately supplying combustible material, a first oxidizing gas having a given oxygen concentration, and a second oxidizing gas having a different oxygen concentration from said first oxidizing gas to the burner; first means for separately directing said first oxidizing gas and a first portion of said combustible material into said combustion tunnel such that said portion of combustible material and said first oxidizing gas mix at least partially within said combustion tunnel to create a flame core; second means for separately directing the remainder of said combustible material and said second oxidizing gas into said combustion tunnel such that said remainer of combustible material and said second oxidizing gas mix together at least partially prior to mixing with said flame core; and means for causing said mixture of combustible material and said second oxidizing gas to subsequently mix with said flame core to create the final flame pattern.
