Abstract (en)
[origin: WO2008011851A1] The invention relates to a flame burner having a nozzle (10) disposed in a head, wherein in addition to annularly disposed gas supply channels (11) the nozzle has a central gas supply opening (12), which has a laval nozzle-like region and a stabilizing region having a consistent diameter connected thereto in the flow direction. In order to flame burn a metallic surface the oxygen gas guided through a central nozzle of a flame burner is incited to oscillate in such a manner, such that a pulsating oxygen flow exiting the nozzle mouth is formed at the speed of sound, or at supersonic speed.
