Abstract

The burner comprises a combustion chamber equipped with a flame retention cone. The flame retention cone comprises a diverging jacket with orifices for the passage of oxygen-carrier gas. A fuel lance provided with radially arranged exit openings has its outlet in an upstream inlet section of the flame retention cone. An igniter is arranged in an oxygen-carrier gas duct outside an ignition opening provided in the area of the fuel lance exit openings. The combustion chamber is accommodated inside an outer tube. The downstream ends of the combustion chamber and the outer tube enclose openings spaced, relative to each other, in the circumferential direction to allow the exit of oxygen-carrier gas. The burner provides for flame stability and low-polluting combustion.
