Description

Die Erfindung bezieht sich auf einen Brenngasverteiler für einen mehrstufigen Brenner vorzugsweise für Heizgeräte.The invention relates to a fuel gas distributor for a multi-stage burner, preferably for heaters.

Mehrstufige Brenner sind gemäß dem Stand der Technik bekannt, um den Modulationsbereich von Brennern auszuweiten. Hierbei werden einzelne Brennerbereiche zu- bzw. abgeschaltet. Gemäß dem Stand der Technik verfügt jedes Brennersegment über ein eigenes Brenngas-Verteilerrohr und jeweils eine gesonderte Gasarmatur.Multi-stage burners are known in the art to extend the modulation range of burners. Here, individual burner areas are switched on or off. According to the prior art, each burner segment has its own fuel gas distributor tube and in each case a separate gas fitting.

Aus FR 2 800 848 A ist ein Brenner mit mehreren Segmenten bekannt, bei dem einzelne Bereiche durch Öffnen und Schleißen von Ventilen in der Gasarmatur zu- und abgeschaltet werden können.Out FR 2 800 848 A a multi-segment burner is known in which individual areas can be switched on and off by opening and closing valves in the gas fitting.

JP 58 221315 A offenbart eine Gasarmatur mit mehreren Ventilen, welche eine gestaffelte Gaszufuhr zulässt, um hiermit den Brenngasvolumenstrom gestuft steuern zu können. JP 58 221315 A discloses a gas valve with multiple valves, which allows a staggered gas supply to hereby be able to control the fuel gas flow rate stepped.

DE 196 05 508 A1 zeigt ein Brenngas-Verteilerrohr mit zwei Brenngasleitungen. Zwei voneinander getrennte Gasarmaturen sind jeweils mit einer der beiden Leitungen verbunden. Brenngasdüsen werden abwechselnd mit je einer Brenngasleitung verbunden. Durch das getrennte Ansteuern der Gasarmaturen können somit zwei Bereiche eines atmosphärischen Injektorbrenners unabhängig voneinander betrieben werden. DE 196 05 508 A1 shows a fuel gas manifold with two fuel gas lines. Two separate gas fittings are each connected to one of the two lines. Fuel gas nozzles are alternately connected to a fuel gas line. Due to the separate control of the gas fittings thus two areas of an atmospheric injector burner can be operated independently.

Der Erfindung liegt die Aufgabe zugrunde, ein Brenngas-Verteilerrohr zu schaffen, die sich durch Kompaktheit und Kostenersparnis auszeichnet.The invention has for its object to provide a fuel gas manifold, which is characterized by compactness and cost savings.

Erfindungsgemäß wird dies dadurch erreicht, dass in dem Verteilerrohr mindestens zwei Gasleitungen integriert sind. Die Integration in ein Bauteil ermöglicht eine kompakte Bauweise. Bei dem Verteilerrohr handelt es sich um ein Strangpressventil. Hierdurch lässt sich das Verteilerrohr besonders einfach herstellen. Die Gasleitungen sind mittels Ventilen voneinander getrennt. Hierdurch kann erreicht werden, dass mindestens eine Gasleitung ab- oder zugeschaltet werden kann. Somit kann optional auf die vorgenannte Gasarmatur mit zwei Ausgängen verzichtet werden und die Zu- beziehungsweise Abschaltung - mit allen Vor- und Nachteilen - direkt am Verteiler erfolgen. Das Ventil ist seitlich am Ventilrohr angeordnet. Das erfindungsgemäße Verteilerrohr dient der getrennten Zuführung des Brenngases auf mindestens zwei Bereiche.According to the invention this is achieved in that at least two gas lines are integrated in the manifold. The integration into a component allows a compact design. The manifold is an extrusion valve. This makes it particularly easy to produce the manifold. The gas lines are separated by valves. In this way it can be achieved that at least one gas line can be switched off or switched on. Thus, optionally, the above-mentioned gas fitting with two outputs can be dispensed with and the connection or disconnection - with all advantages and disadvantages - take place directly at the distributor. The valve is arranged on the side of the valve tube. The distributor pipe according to the invention serves for the separate supply of the fuel gas to at least two areas.

Gemäß den Merkmalen des Anspruchs 2 befindet sich der Ventilkörper in oder an einer Öffnung zwischen den Gasleitungen.According to the features of claim 2, the valve body is in or at an opening between the gas lines.

Gemäß den Merkmalen des abhängigen Anspruchs 3 kann der Ventilkörper innerhalb des Ventilrohres angeordnet sein.According to the features of the dependent claim 3, the valve body may be disposed within the valve tube.

Gemäß den Merkmalen der Ansprüche 4 und 5 kann der Gasanschluss seitlich in Richtung der Erstreckungslinie des Verteilerrohres erfolgen oder auch senkrecht hierzu durch das Verteilerrohr hindurch.According to the features of claims 4 and 5, the gas connection can take place laterally in the direction of the extension line of the distributor tube or also perpendicular thereto through the distributor tube.

Figur 1 zeigt eine Gasarmatur 40 mit einem Brenngaseintritt 41 und zwei Brenngasaustritten 42, 43. In Strömungsrichtung hinter dem Brenngaseintritt 41 ist ein Ventilkörper 45 eines Einlassventils 44 angeordnet. In Strömungsrichtung folgen zwei Ventilkörper 47, 49 zweier Auslassventile 46, 48. Durch die Ventilkörper 47, 49 wird der Übergang zu den zwei Brenngasaustritten 42, 43 versperrt bzw. geöffnet. In Figur 1 ist der Zustand dargestellt, dass sowohl das Einlassventil 44 als auch die Auslassventile 46, 48 geschlossen sind, wodurch kein Brenngas vom Brenngaseintritt zu einem der Brenngasaustritte 42, 43 strömen kann. FIG. 1 shows a gas fitting 40 with a fuel gas inlet 41 and two fuel gas outlets 42, 43. In the flow direction behind the fuel gas inlet 41, a valve body 45 of an inlet valve 44 is arranged. Two valve bodies 47, 49 of two outlet valves 46, 48 follow in the flow direction. The transition to the two fuel gas outlets 42, 43 is blocked or opened by the valve bodies 47, 49. In FIG. 1 the state is shown that both the inlet valve 44 and the exhaust valves 46, 48 are closed, whereby no fuel gas from the fuel gas inlet to one of the fuel gas outlets 42, 43 can flow.

Figur 2 zeigt dieselbe Gasarmatur 40, wobei sowohl das Einlassventil 44 als auch die Auslassventile 46, 48 geöffnet sind, wodurch Brenngas vom Brenngaseintritt 41 zu den beiden Brenngasaustritten 42, 43 strömen kann. Figur 3 zeigt die identisch Gasarmatur in dem Betriebsfall, in dem die Leistung moduliert wird. Das Einlassventil 44 ist geöffnet, das Auslassventil 46 geöffnet, das Auslassventil 48 geschlossen. Hierdurch strömt Brenngas von Brenngaseintritt 41 zum Brenngasaustritt 42, durch den Brenngasaustritt 43 kann kein Brenngas strömen. In Figur 4 ist das Einlassventil 44 geöffnet, das Auslassventil 46 geschlossen und das Auslassventil 48 geöffnet. Nun kann Brenngas aus dem Brenngasaustritt 43 entweichen, während durch den Brenngasaustritt 42 kein Brenngas strömen kann. FIG. 2 shows the same gas valve 40, wherein both the inlet valve 44 and the exhaust valves 46, 48 are opened, whereby fuel gas from the fuel gas inlet 41 to the two fuel gas outlets 42, 43 can flow. FIG. 3 shows the identical gas valve in the operating case in which the power is modulated. The inlet valve 44 is open, the outlet valve 46 is open, and the outlet valve 48 is closed. As a result, fuel gas flows from fuel gas inlet 41 to the fuel gas outlet 42, through the fuel gas outlet 43 can flow no fuel gas. In FIG. 4 the intake valve 44 is open, the exhaust valve 46 is closed and the exhaust valve 48 is opened. Now, fuel gas can escape from the fuel gas outlet 43, while no fuel gas can flow through the fuel gas outlet 42.

Durch unterschiedliche Dimensionierung der Brenner, welche den Brenngasaustritten 42, 43 folgen, kann hierdurch die Leistung nennenswert beeinflusst werden. Ist beispielsweise ein Brenner doppelt so groß wie der andere, so kann ein Drittel der Modulationsleistung mit dem kleinen Brenner abgedeckt werden sowie kleinere Leistungen durch die Modulation dieses Brenners, während bei zwei Drittel Leistungen der größere Brenner betrieben wird und der kleinere abgeschaltet wird. Hierdurch ist eine sehr große Bandbreite möglich.By different dimensioning of the burner, which follow the fuel gas outlets 42, 43, thereby the performance can be significantly influenced. For example, if one burner is twice as large as the other, then one-third of the modulation power can be covered by the small burner and smaller power by the modulation of this Brenners, while at two-thirds power the larger burner is operated and the smaller is switched off. As a result, a very large bandwidth is possible.

Figur 5 zeigt ein erfindungsgemäßes Verteilerrohr 10 mit Gasdüsen 8 und Brenngasanschlüssen 19, 20. Das Verteilerrohr 10 erstreckt sich entlang einer Erstreckungslinie 15, die bei einem Strangpressprofil der Strangpressrichtung entspricht. Figur 6 zeigt dasselbe Verteilerrohr 10 mit zwei internen Gasleitungen 11, 12. Aus Figur 7 geht hervor, dass die Gasleitung 11 über eine Verbindungsbohrung 13 mit einer Brenngasdüse 8 verbunden ist. Figur 8 zeigt dasselbe Verteilerrohr 10 an einer anderen Stelle, an welcher die Gasdüse 8 über eine Verbindungsbohrung 14 mit der Gasleitung 12 verbunden ist. Hierdurch ist es beispielsweise möglich, alternierend Brenngasdüsen 8 jeweils mit der einen Gasleitung 11 und dann mit der anderen Gasleitung 12 zu verbinden. Figur 9 zeigt ein nicht erfindungsgemäßes Verteilerrohr mit einem Ventil 16, das über einen Ventilkörper 17 verfügt, welcher eine Öffnung 18 zwischen der Gasleitung 11 und Gasleitung 12 schließen kann. In Figur 9 ist das Ventil im geöffnetem Zustand zu sehen, in Figur 10 ist dasselbe Ventil in demselben Verteilerrohr in geschlossenem Zustand zu sehen. FIG. 5 shows a distributor tube 10 according to the invention with gas nozzles 8 and fuel gas connections 19, 20. The distributor tube 10 extends along an extension line 15, which corresponds to an extrusion profile of the extrusion direction. FIG. 6 shows the same manifold 10 with two internal gas lines 11, 12. Off FIG. 7 shows that the gas line 11 is connected via a connecting bore 13 with a fuel gas nozzle 8. FIG. 8 shows the same manifold 10 at a different location at which the gas nozzle 8 is connected via a connecting bore 14 with the gas line 12. This makes it possible, for example, to connect fuel gas nozzles 8 alternately to one gas line 11 and then to the other gas line 12. FIG. 9 shows a non-inventive manifold with a valve 16 which has a valve body 17 which can close an opening 18 between the gas line 11 and the gas line 12. In FIG. 9 the valve can be seen in the open state, in FIG. 10 the same valve can be seen in the same manifold in the closed state.

Gemäß der Erfindung ist in Figur 11 und Figur 12 ein Ventil 16 seitlich am Verteilerrohr 10 angeordnet. In Figur 11 ist der Ventilkörper 17 in einer Position, welcher eine Verbindung zwischen der Gasleitung 11 und der Gasleitung 12 freigibt. Demgegenüber ist das Ventil in der Figur 12 geschlossen. Figur 13 zeigt einen Brenngasanschluss 20, welcher dafür sorgt, dass die Gasleitung 12 im Verteilerrohr 10 mit Brenngas versorgt werden kann.According to the invention is in FIG. 11 and FIG. 12 a valve 16 laterally disposed on the manifold 10. In FIG. 11 is the valve body 17 in a position which releases a connection between the gas line 11 and the gas line 12. In contrast, the valve is in the FIG. 12 closed. FIG. 13 shows a fuel gas connection 20, which ensures that the gas line 12 can be supplied in the manifold 10 with fuel gas.

Eine Kombination einer Gasarmatur 40 mit einem erfindungsgemäßen Verteilerrohr 10 ist nicht explizit dargestellt. Es bietet sich an, das Verteilerrohr 10 ohne Ventilkörper 17 zwischen den Gasleitungen 11, 12 zu betrieben, sondern stattdessen je einen der Brenngasaustritt 42, 43 der Gasarmatur 40 mit je einer Gasleitungen 11, 12 des Verteilerrohres 10 zu verbinden und die Enden der Gasleitungen 11, 12, an welchen keine Brenngasanschlüsse 19, 20 angebracht sind, abzudichten.A combination of a gas fitting 40 with a manifold 10 according to the invention is not explicitly shown. It makes sense to operate the manifold 10 without valve body 17 between the gas lines 11, 12, but instead each one of the fuel gas outlet 42, 43 of the gas fitting 40 to connect each with a gas lines 11, 12 of the manifold 10 and the ends of the gas lines eleventh 12, to which no fuel gas connections 19, 20 are attached, to be sealed.
