Abstract
A premixing burner includes a pilot burner formed from two half conical shells and a plurality of main burners arranged around the pilot burner. Each of the main burners is formed with an cylindrical outer wall to contain a main flow. Each of the main burners includes a plurality of vortex generators arranged inside the cylindrical wall about a circumference. In addition, a venturi nozzle is disposed in each of the main burners downstream of the vortex generators. A fuel lance for each of the main burners injects one or both of a gaseous and liquid fuel into the burner as a secondary flow, and an outlet of the lance is positioned to inject the secondary flow in the region of the venturi nozzle having a maximum constriction.
