Abstract

The tube (1) for an atmospheric gas burner, with flame holes through its top surface (7), has gas delivered to its interior by a concentric supply tube (3). It has cooling rods (2) supported above the flame holes, parallel to the axis of the tubes. Three rods of steel or refractory ceramic material can be used, carried by a support (9) half-way along the tube, to cool the cores of the flames. A very wide variety of cooling elements is shown, and supports can be used at different positions on the tube. The rods can be located along a straight line, or can form an arc of a circle spaced from the tube, and different types of support are shown.

Description

Die Erfindung betrifft einen atmosphärischen Gasbrenner mit wenigstens einem langgestreckten, innerhalb einer Brennkammer angeordneten, vorzugsweise metallenen, Brennerrohr, dessen Wandung an ihrer Oberseite Gemischaustrittsöffnungen für ein dem Brennerrohr zugeführtes Gas-Luft-Gemisch aufweist, und mit wenigstens einem, vorzugsweise aus keramischem Material bestehenden, Kühlstab, der im wesentlichen parallel zur Achse des Brennerrohres und im Abstand von der Rohrwandung verlaufend angeordnet ist, wobei über die Gesamtlänge des wenigstens einen Kühlstabes eine einzige Halterung vorgesehen ist.The invention relates to an atmospheric gas burner with at least one elongated, preferably metal, burner tube arranged within a combustion chamber, the wall of which has mixture outlet openings on its top for a gas-air mixture supplied to the burner tube, and with at least one, preferably made of ceramic material, Cooling rod, which is arranged essentially parallel to the axis of the burner tube and at a distance from the tube wall, a single holder being provided over the entire length of the at least one cooling rod.

Aus der US-A-4525141 und aus dem DE-U-8507804 ist ein Gasbrenner bekanntgeworden, bei dem Kühlstäbe in zwei den beiden Endbereichen des Brennerrohres zugehörigen Halterungen gelagert sind, die sich innerhalb der Längserstreckung des Brennerrohres befinden und infolgedessen in mehrfacher Hinsicht störend sind. Diese Halterungen verursachen nicht nur einen erheblichen Aufwand bei ihrer Herstellung und Befestigung, sie behindern auch den Zugang zu den in der Oberseite der Wandung des Brennerrohres angeordneten Gemischaustrittsöffnungen im Falle einer Wartung des Brenners. Dadurch, daß sie den Flammenbereich an beiden Stirnseiten des Brennerrohres gewissermaßen begrenzen, können sie innerhalb ihres Abstandes voneinander einen Hitzestau im Flammenbereich herbeiführen, der zu einem erhöhten Schadstoffausstoß beim Betrieb des Brenners führt. Schließlich erschweren solcherart angeordnete Halterungen auch die Aus wechslung und Montage bzw. Demontage der Kühlstäbe und stören bei der Konzeption der Anordnung des Systems der Gemischaustrittsöffnungen.A gas burner has become known from US-A-4525141 and from DE-U-8507804, in which cooling rods are mounted in two holders associated with the two end regions of the burner tube, which are located within the longitudinal extent of the burner tube and are consequently disturbing in several ways. These brackets not only cause considerable effort in their manufacture and fastening, they also hinder access to the mixture outlet openings arranged in the top of the wall of the burner tube when the burner is serviced. Because they limit the flame area on both ends of the burner tube to a certain extent, they can cause heat accumulation in the flame area within their distance from one another, which leads to increased pollutant emissions during operation of the burner. Finally, mounts arranged in this way also make it difficult Change and assembly or disassembly of the cooling rods and interfere with the design of the arrangement of the system of the mixture outlet openings.

Die Erfindung stellt es sich zur Aufgabe, diese Nachteile zu vermeiden und beruht auf der Erkenntnis, daß das System der Halterung solcher Kühlstäbe im vorliegenden konkreten Fall erheblich vereinfacht werden kann, ohne daß daraus irgendwelche Nachteile resultieren.The object of the invention is to avoid these disadvantages and is based on the knowledge that the system of holding such cooling rods can be considerably simplified in the present specific case without resulting in any disadvantages.

Gemäß dem wesentlichsten Merkmal der Erfindung ist der Kühlstab, und zwar bei Anordnung mehrerer Kühlstäbe jeder Kühlstab, innerhalb seiner Längserstreckung in nur einer einzigen Halterung gelagert.According to the most important feature of the invention, the cooling rod, that is to say when each cooling rod is arranged with a plurality of cooling rods, is mounted within its longitudinal extent in only one holder.

Sind mehrere Kühlstäbe vorgesehen, kann von ihnen jeder in einer einzigen einzelnen Halterung gelagert sein oder sie können in einer einzigen gemeinsamen Halterung gelagert sein.If several cooling rods are provided, each of them can be mounted in a single individual holder or they can be mounted in a single common holder.

Unter Bedachtnahme auf die jeweilige Bauart des Gasbrenners und seines Gehäuses mag es von Vorteil sein, die einzige Halterung etwa in der Längsmitte des Kühlstabes bzw. des Brennerrohres oder in einem der beiden Endbereiche des Kühlstabes bzw. Brennerrohres vorzusehenTaking into account the respective design of the gas burner and its housing, it may be advantageous to provide the only holder approximately in the longitudinal center of the cooling rod or the burner tube or in one of the two end regions of the cooling rod or burner tube

Im folgenden wird die Erfindung anhand von Ausführungsbeispiele darstellenden Zeichnungen näher erläutert. Es zeigt

  • Figure 4 is the associated cross section according to IV-IV of Figure 3.

Die Figuren 1 und 2 zeigen das Brennerrohr 1 eines atmosphärischen Gasbrenners. Diesem Brennerrohr 1, das sich unterhalb einer Brennkammer erstreckt und dessen Wandung an ihrer Oberseite ein System von (nicht dargestellten) Gemischaustrittsöffnungen aufweist, wird das Gas-Luft-Gemisch über das in eine seiner Stirnseiten einmündende koaxiale Mischrohr 3 zugeführt.Figures 1 and 2 show the burner tube 1 of an atmospheric gas burner. The gas-air mixture is fed to this burner tube 1, which extends below a combustion chamber and the wall of which has a system of mixture outlet openings (not shown) on its top side, via the coaxial mixing tube 3 opening into one of its end faces.

Oberhalb der Gemischaustrittsöffnungen und in einem Abstand x von der Oberseite der Wandung des Brennerrohres 1 verlaufen Kühlstäbe 2, die der Ableitung der Hitze aus dem Flammenbereich des Brenners dienen. Diese Kühlstäbe 2 sind in einer Halterung 4 gelagert.Cooling rods 2, which serve to dissipate the heat from the flame area of the burner, run above the mixture outlet openings and at a distance x from the top of the wall of the burner tube 1. These cooling rods 2 are mounted in a holder 4.

Bei der in den Figuren 1 und 2 dargestellten Ausführungsform des Gasbrenners ist über die Gesamtlänge der zueinander und zum Brennerrohr 1 parallelen Kühlstäbe 2 nur eine einzelne, am Brennerrohr 1 befestigte und allen Kühlstäben 2 gemeinsame Halterung 4 vorgesehen, die sich etwa in deren Längsmitte befindet.In the embodiment of the gas burner shown in FIGS. 1 and 2, only a single holder 4 which is fastened to the burner tube 1 and is common to all the cooling rods 2 is provided over the total length of the cooling rods 2 which are parallel to one another and to the burner tube 1 and which is located approximately in the longitudinal center thereof.

Bei der in gleicher Weise in den Figuren 3 und 4 dargestellten Ausführungsform sind gleichfalls nur an einer Stelle des Längsverlaufes der Kühlstäbe 2 Halterungen 4 vorgesehen, sie befinden sich jedoch in einem der beiden Endbereiche des Brennerrohres 1 und lagern jeden Kühlstab 2 einzeln, also in einer eigenen Halterung 4. Alle Kühlstäbe 2 haben dabei den gleichen einheitlichen Abstand x von der Oberseite des Brennerrohres 1.In the embodiment shown in the same way in FIGS. 3 and 4, brackets 4 are likewise only provided at one point in the longitudinal course of the cooling rods, but they are located in one of the two end regions of the burner tube 1 and store each cooling rod 2 individually, that is to say in one own holder 4. All cooling rods 2 have the same uniform distance x from the top of the burner tube 1.
