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 zwei langgestreckten, innerhalb einer Brennkammer zueinander parallel angeordneten Brennerrohren, deren Wandungen an ihrer Oberseite Gemischaustrittsöffnungen für ein diesen Brennerrohren zugeführtes Gas-Luft-Gemisch aufweisen, wobei den Oberseiten dieser, vorzugsweise metallenen, Brennerrohre zumindest ein, vorzugsweise aus keramischem Material bestehender, im wesentlichen zu den Achsen der Brennerrohr paralleler, in einem Abstand von deren Wandungen verlaufender Kühlstab zugeordnet ist.The invention relates to an atmospheric gas burner with at least two elongated burner tubes arranged parallel to one another within a combustion chamber, the walls of which have mixture outlet openings on the top for a gas-air mixture supplied to these burner tubes, the top of these, preferably metal, burner tubes at least one Cooling rod, preferably made of ceramic material and essentially parallel to the axes of the burner tube and at a distance from the walls thereof, is assigned.

Solche Gasbrenner sind aus der US-A-4525141 und der DE-U-8507804 bekannt. Bei diesen vorbekannten Gasbrennern sind Kühlstäbe in zwei den beiden Endbereichen des Brennerrohres zugehörigen Halterungen gelagert, die sich innerhalb der Längserstreckung des Brennerrohres befinden und infolgedessen in mehrfacher Hinsicht störend sind, weil sie im Falle einer Wartung des Brenners den Zugang zu den in der Oberseite der Wandung der Brennerrohre angeordneten Gemischaustrittsöffnungen behindern. Dadurch, daß sich diese Halterungen unmittelbar im Flammenbereich des Brenners befinden, besteht die Gefahr, daß sie einen Hitzestau in diesem Flammenbereich verursachen, der im Brennerbetrieb einen erhöhten Schadstoffausstoß zur Folge hätte. Schließlich erschweren solche Halterungen auch die Auswechslung von Kühlstäben und lassen sich selbst nur gemeinsam mit den Brennerrohren montieren und demontieren.Such gas burners are known from US-A-4525141 and DE-U-8507804. In these known gas burners, cooling rods are mounted in two brackets associated with the two end regions of the burner tube, which are located within the longitudinal extension of the burner tube and are consequently disruptive in several respects because, in the event of burner maintenance, they have access to those in the top of the wall obstruct the mixture outlet openings arranged in the burner tubes. Because these brackets are located directly in the flame area of the burner, there is a risk that they will cause a build-up of heat in this flame area, which would result in increased pollutant emissions during burner operation. Finally, such brackets also make it difficult to replace cooling rods and can only be assembled and disassembled together with the burner tubes.

Aufgabe der Erfindung ist es, diese Nachteile durch eine grundsätzlich andersartige Anordnung der Kühlstäbe zu vermeiden.The object of the invention is to avoid these disadvantages by arranging the cooling rods in a fundamentally different manner.

Gemäß dem wesentlichsten Erfindungsmerkmal ist jeder Kühlstab im Abstand zwischen jeweils einander benachbarten Brennerrohren oberhalb der gemeinsamen Ebene der Oberseiten dieser Brennerrohre verlaufend angeordnet.According to the most important feature of the invention, each cooling rod is arranged to run at a distance between adjacent burner tubes above the common plane of the tops of these burner tubes.

Dadurch befinden sich zwar diese Kühlstäbe in unmittelbarer Nachbarschaft des Flammenbereiches und vermögen ihrer Bestimmung, diesem Flammenbereich Hitze zu entziehen, voll gerecht zu werden, sie sind aber anderseits weitgehend unabhängig von den Brennerrohren ; ihre Halterungen sind daher völlig beliebig gestaltbar, sie behindern den Zugang zu den Gemischaustrittsöffnungen in keiner Weise und bei der Anordnung dieser Gemischaustrittsöffnungen braucht auf Halterungen dieser Kühlstäbe keinerlei Rücksicht genommen werden.As a result, although these cooling rods are located in the immediate vicinity of the flame area and are able to fully meet their purpose of extracting heat from this flame area, on the other hand they are largely independent of the burner tubes; their brackets can therefore be designed in any way, they do not hinder access to the mixture outlet openings in any way and when arranging these mixture outlet openings, no attention need be paid to holders of these cooling rods.

Nach einer bevorzugten Ausführungsform des Erfindungsgegenstandes weisen mehrere zueinander parallele Kühlstäbe einen einheitlichen Abstand von der durch die Oberseiten der Brennerrohre bestimmten Ebene auf.According to a preferred embodiment of the subject matter of the invention, a plurality of cooling rods which are parallel to one another are at a uniform distance from the plane determined by the upper sides of the burner tubes.

Im folgenden wird die Erfindung anhand eines in der einzigen Zeichnungsfigur dargestellten Ausführungsbeispieles erläutert. Diese Zeichnungsfigur stellt einen Querschnitt durch zwei einander benachbarte, zueinander parallel verlaufende Brennerrohre 1 und die ihnen zugeordneten Kühlstäbe 2 dar.The invention is explained below with reference to an embodiment shown in the single drawing figure. This drawing figure shows a cross section through two mutually adjacent, mutually parallel burner tubes 1 and the cooling rods 2 assigned to them.

Im Rahmen der Erfindung werden am günstigsten Brennerrohre 1 mit einer ebenen Oberseite 3 verwendet.In the context of the invention, the cheapest burner tubes 1 with a flat top 3 are used.

Die Kühlstäbe 2 sind dann bei Anordnung mehrerer solcher zueinander paralleler, einen Brennerrost bildender Brennerrohre 1 knapp oberhaibdergemeinsamen Ebene 5 dieser oberseiten 3 in den Abständen 4 vorgesehen, so daß jeweils das einzelne Brennerrohr 1 zwischen zwei einander benachbarten Kühlstäben 2 verläuft. Alle Kühlstäbe 2 liegen in gleicher Höhe und verlaufen zueinander und zu den Brennerrohren parallel, und zwar mit einem einheitlichen Abstand von der durch deren Oberseiten 3 bestimmten Ebene 5.The cooling rods 2 are then provided with arrangement of several such parallel burner tubes 1 forming a burner grate 1 just above the common plane 5 of these top sides 3 at intervals 4, so that the individual burner tube 1 runs between two adjacent cooling rods 2. All cooling rods 2 are at the same height and run parallel to one another and to the burner tubes, with a uniform distance from the plane 5 determined by their top sides 3.

Claims (3)

1. An atmospheric gas burner comprising two elongate burner tubes (1), which extend parallel to each other in a combustion chamber and in their walls are provided on their upper side with mixture exit openings for a gas-air-mixture fed to said burner tubes (1), wherein the upper sides of said preferably metallic burner tubes (1) have cooling rods (2) associated with them, which preferably consist of ceramic material and which are substantially parallel to the axes of the burner tubes (1) and spaced from the surfaces thereof, characterized in that a cooling rod extends in the space (4) between any two adjacent burner tubes (1) and is disposed above the plane (5) which is common to the upper surfaces (3) of said burner tubes (1).
2. A gas burner according to claim 1, characterized in that a plurality of mutually parallel cooling rods (2) are spaced a uniform distance (x) from said plane (5).
3. A gas burner according to claim 1 or 2, characterized by burner tubes (1) having a planar upper surface (3).
