Abstract

The invention relates to a central burner for multi-fuel multiple lance burner systems having a central lance with an inner pipe and an outer pipe. The inner pipe and the outer pipe form an annular clearance duct. A plurality of outer lances are arranged around the central lance. A funnel-like mixing device is provided in the extension of the annular clearance duct in the region of the end of the inner pipe. This funnel-like mixing device has openings in its wall for combustion media to flow through. The outer lances each have a nozzle which has openings along the lateral circumferential area, said openings being arranged asymmetrically.
