Abstract

Atmospheric premix gas burner arrangement with a burner plate which closes off a burner chamber which is connected via at least one mixing pipe to an injector inlet which is acted upon with gas. In order to be able to manufacture such a premix gas burner arrangement in a simple manner, it is envisaged that the mixing pipe is formed by a mixing pipe section (10), shaped from the bottom (3) of the burner plate (2), with a mounted-on burner plate (2) (to the combustion space) and a mixing pipe section (13) shaped from the injector inlet (12), which are both inserted in the other. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Atmosphärische Vormischgasbrenneranordnung mit einer Brennerplatte, die eine Brennerkammer abschließt, die über mindestens ein Mischrohr mit einem Injektoreinlaß, der mit Gas beaufschlagt ist, verbunden ist.The invention relates to an atmospheric premixed gas burner arrangement having a burner plate which closes a burner chamber which is connected via at least one mixing tube to an injector inlet which is supplied with gas.

Bei solchen Vormischgasbrenneranordnungen sind die Mischrohre als separate Teile ausgebildet, die einerseits mit der ebenfalls als Einzelteil ausgebildeten Brennerplatte mit einem ebenfalls als Einzelteil ausgebildeten Injektoreinlauf verbunden sind. Dabei ergeben sich jedoch beim Zusammenbau erhebliche Probleme, da relativ enge Toleranzen eingehalten werden müssen und die Herstellungsgenauigkeit bei den verschiedenen Einzelteilen nicht beliebig gesteigert werden kann.In such premix gas burner arrangements, the mixing tubes are designed as separate parts which, on the one hand, are connected to the burner plate, which is likewise designed as an individual part, with an injector inlet, likewise formed as an individual part. However, considerable problems arise during assembly, since relatively narrow tolerances have to be observed and the manufacturing accuracy of the various individual parts cannot be increased arbitrarily.

Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine Vormischgasbrenneranordnung der eingangs erwähnten Art vorzuschlagen, die sich einfach und mit geringem Montageaufwand herstellen läßt.The aim of the invention is to avoid these disadvantages and to propose a premix gas burner arrangement of the type mentioned at the outset which can be produced simply and with little assembly effort.

Erfindungsgemäß wird dies dadurch erreicht, daß das Mischrohr durch einen aus dem Boden der Brennerplatte ausgeformten Mischrohrabschnitt und einem aus dem Injektoreinlauf ausgeformten Mischrohrabschnitt gebildet ist, welche beide ineinander gesteckt sind.This is achieved according to the invention in that the mixing tube is formed by a mixing tube section formed from the bottom of the burner plate and by a mixing tube section formed from the injector inlet Mixing tube section is formed, which are both inserted into one another.

Durch diese Maßnahmen kann die gesamte Vormischgasbrenneranordnung aus lediglich zwei Teilen hergestellt werden, die einfach miteinander verbunden werden können. Außerdem ergibt sich dadurch eine sehr geringe Länge der Dichtkanten, verglichen mit den bekannten Lösungen, bei denen sich an beiden Seiten der Mischrohre Dichtkanten ergeben.Through these measures, the entire premix gas burner arrangement can be produced from only two parts, which can be easily connected to one another. In addition, this results in a very short length of the sealing edges compared to the known solutions, in which sealing edges result on both sides of the mixing tubes.

Dabei kann vorgesehen sein, daß der aus dem Boden der Brennerplatte ausgeformte Mischrohrabschnitt an seinem freien Ende zu einer Muffe ausgeformt ist.It can be provided that the mixing tube section formed from the bottom of the burner plate is formed into a sleeve at its free end.

Auf diese Weise können die beiden Teile der Vormischgasbrenneranordnung besonders leicht durch weitere Hilfsmittel zusammengebaut werden.In this way, the two parts of the premix gas burner arrangement can be assembled particularly easily by further aids.

Weiter kann bei einer erfindungsgemäßen Vormischgasbrenneranordnung, bei der die Brennerplatte und der Injektoreinlaß über mehrere Mischrohre gleichmäßig miteinander verbunden sind, die in Reihen und Spalten angeordnet sind, vorgesehen sein, daß entlang einer jeden Reihe von Mischrohren ein Gasverteilrohr angeordnet ist.Furthermore, in a premix gas burner arrangement according to the invention, in which the burner plate and the injector inlet are uniformly connected to one another via a plurality of mixing tubes which are arranged in rows and columns, it can be provided that a gas distribution tube is arranged along each row of mixing tubes.

Auf diese Weise ergibt sich ein sehr einfacher Aufbau der Vormischgasbrenneranordnung und eine Speisung der einzelnen Brennerkammern mit dem Gas-Luft-Gemisch.This results in a very simple construction of the premix gas burner arrangement and a feeding of the individual burner chambers with the gas-air mixture.

Weiter kann vorgesehen sein, daß der Boden der Brennerplatte mit umlaufenden aufstehenden Wänden versehen ist, die in ihren oberen Bereichen mit einer umlaufenden Ausformung versehen ist, auf die ein mit umlaufenden Wänden, die zu den Wänden des Bodens im wesentlichen gegengleich geformt und auf die Wände des Bodens aufschnappbar sind.Furthermore, it can be provided that the bottom of the burner plate is provided with circumferential upstanding walls, which is provided in its upper regions with a circumferential formation, one with circumferential walls, which is shaped substantially in the opposite direction to the walls of the floor and on the walls of the bottom can be snapped on.

Auf diese Weise kann die Brennerplatte sehr einfach hergestellt werden.In this way, the burner plate can be manufactured very easily.
