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 bezieht sich auf einen atmosphärischen Gasbrenner mit wenigstens einem langgestreckten, innerhalb einer Brennkammer angeordneten Brennerrohr, dessen Wandung an ihrer Oberseite Gemischaustrittsöffnungen für ein dem Brennerrohr zugeführtes Gas-Luft-Gemisch aufweist, wobei diesem vorzugsweise metallenen Brennerrohr eine Halterung für zumindest zwei vorzugsweise aus Keramischem Material bestehende, im wesentlichen zur Achse des Brennerrohres parallele, in einem Abstand von der Rohrwandung verlaufende Kühlstäbe zugeordnet ist.The invention relates to an atmospheric gas burner with at least one elongated burner tube arranged within a combustion chamber, the wall of which has mixture outlet openings on its upper side for a gas-air mixture supplied to the burner tube, this preferably metallic burner tube having a holder for at least two, preferably made of ceramic Material existing, essentially parallel to the axis of the burner tube, at a distance from the tube wall extending cooling rods is assigned.

Solche Gasbrenner sind aus der US-A-4 525 141 und aus der DE-U-8 507 804 bekannt. Bei diesen vorbekannten Gasbrennern sind einzelne Kühlstäbe in zwei den Endbereichen des Brennerrohres zugehörigen Halterungen einzeln gelagert; sie müssen in diese Halterungen einzeln eingesetzt und zum Austausch einzeln aus diesen Halterungen entfernt werden. Dies ist mit einem erheblichen Zeit- und Müheraufwand verknüpft, den zu vermeiden sich die vorliegende Erfindung zur Aufgabe stellt.Such gas burners are known from US-A-4,525,141 and from DE-U-8,507,804. In these known gas burners, individual cooling rods are individually supported in two holders associated with the end regions of the burner tube; they must be inserted individually into these brackets and removed individually from these brackets for exchange. This is associated with considerable expenditure of time and effort which the present invention has as its object to avoid.

Gemaß dem wesentlichsten Erfindungsmerkmal bilden zumindest zwei solche Kühlstäbe gemeinsam eine einstückige, mittels der Halterungen an beiden Seiten des am Brennerrohres befestigbare Einheit.According to the most important feature of the invention, at least two such cooling rods together form a one-piece unit which can be attached to the burner tube by means of the holders on both sides.

Eine solche Einheit läßt sich einfach und problemlos handhaben und kann sehr exakt auf bestimmte Typen von Brennerrohren bemessen werden, so daß sie sich auch von wenig fachkundigen Benutzer, zuverlässig in ihrer Soll-Lage am Brennerrohr anbringen läßt.Such a unit can be handled easily and without problems and can be dimensioned very precisely to certain types of burner tubes, so that it can be reliably attached to the burner tube in its desired position even by inexperienced users.

Entsprechend einer vorteilhaften Weiterbildung sind die Kühlstäbe derart gekröpft ausgebildet, daß eine Ausnehmung für ein Zündelement entsteht.According to an advantageous further development, the cooling rods are cranked in such a way that a recess for an ignition element is created.

Im folgenden wird die Erfindung anhand von Ausführungsbeispielen erläuter, die in den Zeichnungen dargestellt sind. Es zeigen

  • Figur 1 die Seitenansicht eines Brennerrohres mit der daran befestigten, aus Kühlstäben bestehenden Einheit.
  • Figur 2 ist ein Querschnitt nach II-II der Figur 1 und
  • Figur 3 eine Draufsicht auf diese Ausführungsform.
  • Figur 4 zeigt in gleicher Darstellungsweise wie die Figur 1 eine abgewandelte Ausführungsform,
  • Figur 5 ist deren Querschnitt nach V-V der Figur 4 und
  • Figur 6 ein Teil-Längsschnitt durch den Endbereich.
  • Figur 7 stellt teils in Längsansicht, teils im Längsschnitt eine weitere Ausführungsvariante dar,
  • Figur 8 ist der zugehörige Querschnitt nach VIII-VIII der Figur 7 und
  • Figur 9 die zugehörige Draufsicht.
  • Figur 10 ist die Längsansicht einer weiteren Ausführungsform und
  • Figur 11 die zugehörige Draufsicht.

Gemäß der in den Figuren 1 bis 3 dargestellten Ausführungsform bilden drei Kühlstäbe 2 gleicher Länge gemeinsam eine einstückige, zwischen den beiden dem Brennerrohr 1 an beiden Stirnseiten als Halterungen 3 angefügten Stirnscheiben einsetzbare Einheit 4, die von zwei Tragarmen 5 dieser Stirnscheiben gehalten wird. Ein in die eine Stirnseite des Brennerrohres 1 koaxial einmündendes, der Zufuhr des Gas-Luft-Gemisches dienendes Mischrohr ist mit 6 bezeichnet. Die beiden Tragarme 5 bilden eine Ausnehmung 7 für _ hier nicht dargestelltes _ gegen die Gemischaustrittsöffnungen des Brennerrohres 1 gerichtetes Zündelement.According to the embodiment shown in Figures 1 to 3, three cooling rods 2 of the same length together form an integral unit 4, which can be inserted between the two end disks attached to the burner tube 1 on both end faces as holders 3 and which is held by two support arms 5 of these end disks. A mixing tube which coaxially opens into one end of the burner tube 1 and serves to supply the gas-air mixture is designated by 6. The two support arms 5 form a recess 7 for an ignition element (not shown here) directed against the mixture outlet openings of the burner tube 1.

Die Figuren 4 bis 6 zeigen eine Ausführungsform, derzufolge eine an beiden Stirnseiten des Brennerrohres 1 mittels als Stirnscheiben ausgebildeter Halterungen 3 anfügbare Einheit 4 aus drei Kühlstäben 2 und diesen Stirnscheiben besteht, also mit den Halterungen 3 gemeinsam einstückig ausgebildet ist.FIGS. 4 to 6 show an embodiment according to which a unit 4 which can be attached to both end faces of the burner tube 1 by means of holders 3 designed as end plates consists of three cooling rods 2 and these end plates, that is to say is formed in one piece with the holders 3.

Auch diese Einheit 4 bildet eine Ausnehmung 7 für ein (nicht dargestelltes) Zündelement.This unit 4 also forms a recess 7 for an ignition element (not shown).

Auch die Ausführungsform nach den Figuren 7 bis 9 zeigt eine auf das Brennerrohr 1 aufsetzbare, aus den als Stirnscheiben ausgebildeten Halterungen 3 und Kühlstäben 2 bestehende einstückige Einheit 4, die darüber hinaus in einem ihrer Stirnbereiche aus noch eine Paar von Zündelementen 8 enthält.The embodiment according to FIGS. 7 to 9 also shows one which can be placed on the burner tube 1 and is made of end plates trained brackets 3 and cooling rods 2 existing one-piece unit 4, which also contains a pair of ignition elements 8 in one of its end regions.

Eine aus Kühlstäben 2 und Halterungen 3 bestehende Einheit 4 ist in den Figuren 10 und 11 veranschaulicht. Bei ihr bestehen die Halterungen 3 aus Winkelstücken, deren Winkelschenkel an der Wandung des Brennerrohres 1 anliegend befestigt sind.A unit 4 consisting of cooling rods 2 and holders 3 is illustrated in FIGS. 10 and 11. In her, the brackets 3 consist of angle pieces, the angle legs of which are attached to the wall of the burner tube 1.
