   Das den   Flammeubogen   unmittelbar umgebende Rohr 1 kann auch von einem zweiten Rohre   i   umschlossen sein, 80 dass ein Zwischenraum entsteht, in dem man ein Kühlmittel kreisen lässt. 



  Als solches kann man das im Flammenbogen zu behandelnde Gas benutzen, welches hiebei vorgewärmt wird (Fig. 4). 



   Durch Zusatz von Sauerstoff zu der der Einwirkung des Flammenbogens ausgesetzten Luft kann die Ausbeute an   8tickstoffoxyden   beträchtlich gesteigert werden. 



   PATENT-ANSPRÜCHE : 
1. Verfahren zur Gewinnung von Stickoxyden aus   Stickston-Sauerstongemischen   mittels des elektrischen Flammenbogens unter fortwährendem Absaugen der Gase aus dem heissesten Teile des   Fiammenbogens   mittels gekühlter Rohre, dadurch gekennzeichenet, dass behufs Vermeidung des Ausweichens des Flammenbogens vor den gekühlten Rohren ein Flammenbogen von nahezu unveränderlicher Lage erzeugt wird, u. zw. entweder dadurch, dass der Flammenbogen von einem nicht zu weiten Rohre umgeben ist, durch welches die Absaugrohre geführt werden, oder durch Anwendung eines lotrechten Flammenbogens oder durch Anwendung eines lotrechten und mit einem   nicht zu   weiten Rohre umgebenen Flammenbogens.

   The pipe 1 immediately surrounding the flame arc can also be enclosed by a second pipe i, 80 so that an intermediate space is created in which a coolant is allowed to circulate.



  The gas to be treated in the flame arc can be used as such, which is preheated here (Fig. 4).



   By adding oxygen to the air exposed to the action of the flame arc, the yield of nitrogen oxides can be increased considerably.



   PATENT CLAIMS:
1. Process for the production of nitrogen oxides from nitrogen-oxygen mixtures by means of the electric flame arc with continuous suction of the gases from the hottest part of the flame arc by means of cooled pipes, characterized in that in order to avoid the evasion of the flame arc in front of the cooled pipes, an arc of flame of an almost invariable position is generated, u. either by the fact that the flame arc is surrounded by a tube that is not too wide through which the suction tubes are guided, or by using a vertical flame arc or by using a vertical flame arc surrounded by a tube that is not too wide.
