Abstract

Gas-fired appliance with a main burner equipped with a main-burner nozzle and a pilot burner equipped with a pilot-burner nozzle, and also a thermoelement arranged in the main-burner region and associated with a safety circuit, in which appliance the axis (13) of the pilot burner (3) extends at a distance from the axis (9) of the thermoelement (8). The axis of the pilot-burner nozzle is preferably crosswise with respect to the axis of the thermoelement, the axes may also extend in one plane, in which the axis of the pilot burner is adjacent at a distance. <IMAGE>

Description

Die Erfindung betrifft ein gasbeheiztes Gerät mit einem mit einer Hauptbrennerdüse versehenen Hauptbrenner und einem Zündbrenner sowie einer diesem zugeordneten Zündbrennerdüse und einem im Hauptbrennerbereich angeordneten, einer Sicherheitsschaltung zugehörigen Thermoelement.The invention relates to a gas-heated device with a with a main burner nozzle and a main burner Pilot burner and a pilot burner nozzle assigned to it and one located in the main burner area, one Safety circuit associated thermocouple.

Aufgabe der Erfindung ist eine in Hinsicht auf die Betriebssicherheit besonders günstige Anordnung dieser Gerätebestandteile.The object of the invention is one with regard to Operational safety particularly favorable arrangement of this Device components.

Erfindungsgemäß verläuft die Achse der Zündbrennerdüse im Abstand von der Achse des Thermoelementes.According to the invention, the axis of the pilot burner nozzle runs at a distance from the axis of the thermocouple.

Bekanntlich kann die Zündflamme bei hoerh Kohlendioxidkonzentration im Raum erlöschen. Steht die Zündflamme unmittelbar vor dem Thermoelement, kann sie sich am Thermoelement aufhängen und den Abschaltvorgang behindern.As is well known, the pilot flame can be found at high carbon dioxide concentrations go out in the room. The pilot light is on immediately in front of the thermocouple, it can be attached to the thermocouple hang up and hinder the shutdown process.

Dank der erfindungsgemäßen Lösung ergibt sich eine hohe Sicherheit im Bereich der Zündung: Bei abnehmendem Düsendruck wird die Flamme kürzer und damit der Abstand zum Thermoelement größer, hingegen bleibt der Abstand zum Hauptbrenner stets gleich. Die Ist-Temperatur des Thermoelementes ist somit unabhängig vom jeweiligen Düsendruck.Thanks to the solution according to the invention, the result is high Ignition safety: With decreasing nozzle pressure the flame becomes shorter and thus the distance to the Thermocouple larger, however, the distance to the Main burner always the same. The actual temperature of the thermocouple is therefore independent of the respective nozzle pressure.

Nach der bevorzugten Ausführungsform des Erfindungsgegenstandes verläuft die Achse der Zündbrennerdüse zur Achse des Thermoelementes gekreuzt.According to the preferred embodiment of the subject matter of the invention the axis of the pilot burner nozzle runs to Crossed axis of the thermocouple.

Gemäß einem weiteren Erfindungsmerkmal verlaufen die Achse des Thermoelementes und die Achse der Zündelektrode zweckmäßigerweise in einer Ebene, der die Achse des Zündbrenners mit Abstand benachbart ist.According to a further feature of the invention, the Axis of the thermocouple and the axis of the ignition electrode  Expediently in one plane, the axis of the pilot burner is adjacent at a distance.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in den Zeichnungen schematisch veranschaulicht, u. zw. zeigtAn embodiment of the subject of the invention is schematically illustrated in the drawings, u. between shows

Fig. 1 die Bestandteile des Gerätes in einer Seitenansicht und die Fig. 1 shows the components of the device in a side view and

Fig. 2 in einer Stirnansicht. Fig. 2 in a front view.

Im einzelnen zeigen die Zeichnungen die Gaszufuhrleitung 1 mit der Mischdüse 2 und dem Zündbrenner 3. Aus der Gaszufuhrleitung 1 sind auch ein oder mehrere Hauptbrennerdüsen 10 gespeist, denen Injektorrohre 5 zugeordnet sind, die zu Hauptbrennkammern 11 führen.In detail, the drawings show the gas supply line 1 with the mixing nozzle 2 and the pilot burner 3 . One or more main burner nozzles 10 , to which injector tubes 5 are assigned, which lead to main combustion chambers 11 , are also fed from the gas supply line 1 .

Seitlich der Gaszufuhrleitung 1 verläuft - beispielsweise parallel zu ihr - die Achse 6 einer Zündelektrode 7 und ist in den Bereich des Kernes der Zündflamme 4 gerichtet.The axis 6 of an ignition electrode 7 runs to the side of the gas supply line 1 , for example parallel to it, and is directed into the region of the core of the ignition flame 4 .

In den Bereich der Spitze der Zündflamme 4 erstreckt sich das Thermoelement 8, dessen Achse 9 parallel zur Achse 6 der Zündelektrode 7 verläuft.In the area of the tip of the pilot flame 4 extends the thermocouple 8 , the axis 9 of which extends parallel to the axis 6 of the ignition electrode 7 .

Wie Fig. 2 zeigt, verlaufen die Achse 9 des Thermoelementes 8 und die Achse 6 der Zündelektrode 7 in einer senkrechten Ebene 12, zu der die Achse des Zündbrenners 3 mit Abstand benachbart ist und kreuzend verläuft.As shown in FIG. 2, the axis 9 of the thermocouple 8 and the axis 6 of the ignition electrode 7 run in a vertical plane 12 , to which the axis of the pilot burner 3 is spaced apart and crosses.

Durch den seitlichen Versatz zwischen der Achse 13 des Zündbrenners 3, die auch die Achse der Zündflamme 4 ist, wird das Thermoelement 8 nahezu tangential von der Zündflamme 4 angespült. Der Zündbrenner 3 ist so ausgerichtet, daß die Achse 13 nahezu mittig zwischen der nächstbenachbarten Brennerkammer 11 und dem Thermoelement 8 verläuft, wobei die Brennerkammern 11 unter Belastung von Zwischenräumen parallel zueinander stehen und die Ebene 12 mittig senkrecht zwischen zwei Brennerkammern 11 liegt.Due to the lateral offset between the axis 13 of the pilot burner 3 , which is also the axis of the pilot flame 4 , the thermocouple 8 is washed almost tangentially by the pilot flame 4 . The pilot burner 3 is aligned such that the axis 13 runs almost centrally between the next-adjacent burner chamber 11 and the thermocouple 8 , the burner chambers 11 being parallel to one another under the load of gaps and the plane 12 lying vertically in the middle between two burner chambers 11 .
