Gasbrenner. Patentiert im Deutschen Reiche vom 20. April1912 ab.Gas burner. Patented in the German Empire on April 20, 1912.

Die Erfindung bezieht sich auf Gasbrenner, bei denen in der Abdeckplatte des von einer Hülse umgebenen Brennerkopfes eine oder mehrere zur Erzeugung der Nutzflamme dienende Austrittsöffnungen und _ in der Seitenwandung des Kopfes ein oder mehrere Gasaustrittskanäle zur Erzeugung der die Zündung der Nutzflamme sichernden Stichflammen vorgesehen sind.The invention relates to gas burners in which in the cover plate of one Sleeve surrounded burner head one or more serving to generate the useful flame Outlet openings and one or more gas outlet channels in the side wall of the head are provided for generating the jetting flames securing the ignition of the useful flame.

ίο Es sind bereits derartige Gasbrenner bekannt geworden, bei denen außer der Öffnung für die Stichflamme . seitliche Strahlöffnungen für Zündflämmchen vorgesehen sind. Diese Brenner sind aber derart ausgebildet, daß bei einer plötzlichen Zunahme des Druckes in dem Gaszuleitungsrohr gerade in dem Teil, in dem die seitlichen Strahlöffnungen vorgesehen sind, die größte Druckzunahme stattfindet, so daß die Gefahr besteht, daß beim Ausblasen der Nutzflamme auch die Zündflämmchen ausgeblasen werden.ίο Such gas burners are already known become, where except for the opening for the jet flame. lateral jet openings for ignition flames are provided. However, these burners are designed in such a way that at a sudden increase in pressure in the gas supply pipe just in the part in which the lateral jet openings are provided, the greatest pressure increase takes place, so that there is a risk that when the useful flame is blown out, the ignition flames will also be blown out will.

Zwecks Beseitigung dieses Übelstandes wird gemäß vorliegender Erfindung dem Innenraum des Brennerkopfes ein größerer Querschnitt als dem in der Brennerkopf achse liegenden Gaseintrittskanal gegeben, so daß die seitliche oder die seitlichen Zündflämmchen sowie . eine zwischen dem Brennerkopf und der ihn umgebenden Hülse gelegene Gasschicht von den Druckschwankungen im Gaszuleitungsrohr nicht beeinflußt werden und die Gasstrahlen, welche aus einem oder mehreren gegen die Innenwandung der genannten Hülse gerichteten Kanälen der Brennerkopfplatte ausströmen, selbst bei starken Druckschwankungen des Gasgemisches die Zündung der Nutzflamme sichern.In order to eliminate this inconvenience, according to the present invention, the interior of the burner head has a larger cross-section than that lying in the axis of the burner head Gas inlet channel given, so that the side or the side ignition flames as well . a layer of gas located between the burner head and the sleeve surrounding it the pressure fluctuations in the gas supply pipe are not influenced and the gas jets, which of one or more against the inner wall of said sleeve directed channels of the burner head plate, even with strong pressure fluctuations of the gas mixture ensure the ignition of the useful flame.

Der Mischkammer 1 wird das Gas durch das mit einem Ventil ausgestattete Rohr 3 und atmosphärische Luft durch das an der gegenüberliegenden Seite der Mischkammer angeordnete Rohr 2 zugeführt, während durch die Düse 5 des mit einem Ventil ausgestatteten Rohres 4 gepreßte Luft in die Mischkammer geführt wird. Soll das in der Kammer 1 erzeugte Gasgemisch verschiedenen Verbrauchsstellen zugeführt werden, so wird es von der Mischkammer in die Verteilungskammer 6 geleitet und von da aus durch die biegsamen Röhren 7, 8 den Brennern 22 zugeführt; bei nur einer Verbrauchsstelle wird das gemischte Gas unmittelbar von der Mischkammer 1 dem Brenner 22 zugeführt.The mixing chamber 1 is the gas through the valve equipped with a pipe 3 and atmospheric air through the one located on the opposite side of the mixing chamber Tube 2 is supplied while air is forced into the mixing chamber through the nozzle 5 of the valve-equipped tube 4 to be led. If the gas mixture generated in the chamber 1 is to be fed to various consumption points, it is from the Mixing chamber passed into the distribution chamber 6 and from there through the flexible Tubes 7, 8 fed to the burners 22; if there is only one point of consumption, it is mixed Gas is fed directly from the mixing chamber 1 to the burner 22.

Der Brenner 22 besteht aus dem Verbindungsstück 11 mit dem in. das letztere eingeschraubten Kopf ίο und dem auf die Außenseite des Verbindungsstückes 11 geschraubtenThe burner 22 consists of the connector 11 with the screwed into the latter Head ίο and screwed onto the outside of the connector 11

Claims

Enclosing piece (cylinder) 9 of different lengths.

The gas outlet openings are in the burner head plate 10 12, 13, 14 and 15 attached, at which the useful flame is generated, and furthermore are smaller, oblique in the plate against the cylinder wall 9 directed channels i6, 17, 18 arranged through which smaller Gas quantities are guided against the cylinder wall. In the side wall of the burner head 10, directly below the inclined and small channels 16, 17, 18 of the Horizontal flow channels are attached to the top plate, of which in FIG the channels 19, 20 corresponding to the holes 18, 17 of the head are drawn.

In the known similar burners, the flame, when exiting through the tube 4 Air of too much pressure is too far from the outlet openings of the burner head blown off so that the flame goes out. In that the interior of the burner head 10 has a larger cross section than the axis in the direction of the burner head lying inflow channel for the gas mixture, becomes a hollow cylindrical gas layer formed, which feeds the flame at the outer mouths of the passage channels 19, 20 or burning when the flames generated on the burner head plate are closed by a strong compressed air flow are blown off.

The purpose of the small and obliquely outwardly directed channels 16, 17, 18 is to small amounts of flammable gases generated directly at the openings 19, 20 To promote pilot flames, so that the gases exiting through the burner head from the pilot lights burning quickly and safely at the side openings of the burner head be ignited. If the obliquely directed channels 16, 17, 18 were to be omitted, so the pilot flames emerging from the holes 19, 20 would go out before the The bulk of the gas flowing out through the head would be re-ignited.

By introducing atmospheric air into the mixing chamber 1 through the pipe 2 the oxygen supply is increased, the combustion is completed and a considerable one Part of the compressed air flowing in through the pipe 4 is saved.

Sponsorship τ claim:

Gas burner with one or more outlet openings used to generate the useful flame in the cover plate of the burner head surrounded by a sleeve and one or more. in the side wall of the head attached gas outlet channels to generate the ignition of the Jet flames securing useful flame, characterized in that the interior of the burner head (10) has a larger cross-section has as the gas inlet channel located in the burner head axis. so that the side on the channels (19, 20) generated ignition flames and between the Burner head (10) and the sleeve (9) located gas layer from the pressure fluctuations of the gas mixture in the supply pipe are little influenced and under mediation the gas jets, which through one or more against the inner wall of the sleeve (9) directed channels (16, 17, 18) of the burner head plate out, secure the ignition of the useful flame even with strong pressure fluctuations in the gas mixture.
