Method and apparatus for generating highly luminous flame

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.

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 a first and second 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 said first combustible material into said combustion tunnel such that said first 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 said second combustible material and said second oxidizing gas into said combustion tunnel such that said second 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.

• and
• means for causing said mixture of said second combustible material and said second oxidizing gas to subsequently mix with said flame core to create the final flame pattern.
