Method and apparatus for high temperature heating, melting, refining and superheating of materials, such as steel scrap, metals, ceramics or glass. The invention provides an economizing method of hydrocarbon fluid fuel combustion in an ongoing flame in a liquid cooled combustion chamber by separately supplying streams of fuel and at least two oxidizing gases wherein a first oxidizing gas reacts with the fuel, and a second oxidizing gas is directed about the flame core to further react with the fuel, while controlling the flow of the fuel, the oxidizing gases and cooling liquid to provide the required heat input, combustion product chemistry, temperature, velocity, emissivity and combustion block temperature. Also disclosed are burners for carrying out the invention.

An economizing method of hydrocarbon fluid fuel combustion in an ongoing hydrocarbon flamed formed in a combustion chamber within a fluid cooled combustion block, to reduce the consumption of fuel and pure oxygen in heating processes, comprising the steps of: separately supplying hydrocarbon fluid fuel and two different oxygen based oxidizing gases to a fluid cooled combustion chamber; directing said first oxidizing gas having a given oxygen concentration in a jet along the central axis of the combustion chamber; directing said hydrocarbon fuel into said combustion chamber in a plurality of jets about the central jet of said first oxidizing gas so that said hydrocarbon fuel is caused to be mixed with said first oxidizing gas to stabilize combustion within the combustion chamber; directing said second oxidizing gas having different oxygen concentration from said first oxidizing gas into said combustion chamber in a plurality of jets directed to mix inside said combustion chamber with said hydrocarbon fuel in the flame core, and to mix with the hydrocarbon fuel outside said combustion chamber, creating the final flame pattern; and controlling the flow if said hydrocarbon fuel and said two oxidizing gases.
