Abstract (en)

[origin: EP0751346A1] Flow ducts (8,9) for the mixture of fuel gas and heating oxygen are positioned around the central cutting duct. The flow ducts are continuously milled from the mouth of the fuel gas passage as far as the bottom part (12) of the first and second rotary part (1,11) of the burner cutting nozzle. The first rotary part tapers in a truncated cone shape in the bottom part. A central inner hole in the second rotary part tapers in a truncated cone shape in its bottom part, so that the flow ducts point inwards.
