Abstract

The burner has a combustion chamber (1), which is bounded by a wall (2a) with a window-like aperture (5) through which a nozzle (3) injects fuel, or a fuel mixture (4). The nozzle is arranged on the side of the wall which faces away from the chamber. The nozzle has a sliding or pivoting (8) mounting, and has an end wall or has an outlet opening with an end wall, which faces towards the chamber. In a first position this aligns with the aperture, and in a second position it is shielded by a wall, especially the wall which bounds the combustion chamber.

Description

Die Erfindung betrifft einen Brenner mit einem Brennerraum, wobei eine den Brennerraum begrenzende Wand eine fensterartige Öffnung hat, durch die eine Düse Brennstoff oder ein Verbrennungsgemisch einspritzt, wobei die Düse an der dem Brennerraum abgewandten Seite der begrenzenden Wand angeordnet ist.The invention relates to a burner with a burner chamber, a wall delimiting the burner chamber having a window-like opening through which a nozzle injects fuel or a combustion mixture, the nozzle being arranged on the side of the delimiting wall facing away from the burner chamber.

Bei den heute verwendeten Brennern steht die Einspritzdüse in ständigem Kontakt mit dem Brennerraum. Wird der Brenner z.B. in einem Partikelfiltersystem eingesetzt, bei dem ein Filter den Ruß aus Motorenabgasen herausfiltert, wobei der sich auf dem Filter ablagernde Ruß von Zeit zu Zeit mittels des Brenners abgebrannt wird, so ist die Düse auch während der Betriebspausen, also zwischen den Abbrennphasen bzw. Regenerationsphasen mit dem Brennerraum in ständigem Kontakt. Der in den Motorenabgasen befindliche Ruß und Schmutz findet den Weg durch die fensterartige Öffnung des Brennerraums, durch die der Brennstoff, insbesondere Öl, sowie Luft in den Brennerraum mittels der Düse eingespritzt wird. Es besteht somit die Gefahr, daß während der Betriebspausen des Brenners der in den Abgasen befindliche Ruß die Düse verdreckt und im schlimmsten Fall verstopft, so daß ein Abbrennen des auf dem Filter befindlichen Rußes nicht mehr möglich ist. Es sind dann aufwendige Wartungs- und Säuberungsarbeiten erforderlich, um den Brenner wieder betriebsbereit zu machen. Ist die Düse zu stark verschmutzt, kann es passieren, daß die Düse vollständig ausgewechselt werden muß, was die Wartungskosten zusätzlich erhöht.With the burners used today, the injection nozzle is in constant contact with the burner chamber. If, for example, the burner is used in a particle filter system in which a filter filters out the soot from engine exhaust gases, and the soot deposited on the filter is burned off from time to time by the burner, the nozzle is also inoperative, i.e. between the burn-off phases or regeneration phases in constant contact with the burner chamber. The soot and dirt in the engine exhaust gases find their way through the window-like opening of the burner chamber through which the fuel, in particular oil, and air are injected into the burner chamber by means of the nozzle. It exists thus the danger that during the breaks in operation of the burner, the soot in the exhaust gases will dirty the nozzle and, in the worst case, clog it, so that burning of the soot on the filter is no longer possible. Extensive maintenance and cleaning work are then required to make the burner ready for operation again. If the nozzle is too dirty, it may be necessary to replace the nozzle completely, which increases the maintenance costs.

Aufgabe der Erfindung ist es daher, einen Brenner einfacher Konstruktion und geringer Abmessungen und wenigen Teilen bereitzustellen, bei dem ein Verrußen bzw. Verschmutzen der Düse während der Betriebspausen des Brenners verhindert wird, wodurch die Wartungskosten gesenkt und die Standzeiten des Brenners verlängert werden. Zusätzlich soll die Düse während der Betriebspausen des Brenners gegen die vom Brennerraum zurückstrahlende Hitze geschützt sein.The object of the invention is therefore to provide a burner of simple construction and small dimensions and few parts, in which sooting or soiling of the nozzle is prevented during breaks in operation of the burner, thereby reducing maintenance costs and extending the service life of the burner. In addition, the nozzle should be protected against the heat radiating from the burner chamber during breaks in operation.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Düse verschieb- oder verschwenkbar gelagert ist, derart, daß in einer ersten Position die dem Brennerraum zugewandte Stirnseite der Düse bzw. die Düsenaustrittsöffnung mit der fensterartigen Öffnung der begrenzenden Wand fluchtet und in einer zweiten Position die dem Brennerraum zugewandte Stirnseite der Düse bzw. die Düsenaustrittsöffnung von einer Wand insbesondere von der begrenzenden Wand des Brennerraums abgeschirmt ist. Durch das Verschieben oder Verschwenken der Düse wird die Düse nur dann fluchtend vor die fensterartige Öffnung der Brennerraumwand positioniert, wenn der Brenner in Betrieb genommen wird.This object is achieved in that the nozzle is mounted displaceably or pivotably, such that in a first position the end face of the nozzle facing the burner chamber or the nozzle outlet opening is aligned with the window-like opening of the delimiting wall and in a second position the The end face of the nozzle facing the burner chamber or the nozzle outlet opening is shielded from a wall, in particular from the delimiting wall of the burner chamber. By moving or pivoting the nozzle, the nozzle is only aligned in front of the window-like opening of the burner chamber wall when the burner is started.

In den Betriebspausen wird die Düse vorteilsmäßig so positioniert, daß sie nicht mehr fluchtend vor der fensterartigen Öffnung ist, sondern von einer Wand, insbesondere der Brennerraumwand vom Brennerraum getrennt bzw. abgeschirmt ist. Hierdurch wird während der Betriebspausen zum einen ein Verschmutzen bzw. Verrußen der Düse verhindert und zum anderen die Düse vor thermischer Belastung geschützt, wodurch die Systemsicherheit sowie die Lebensdauer der Düse entschieden erhöht wird und zusätzlich eine konstante Brennerleistung gewährleistet ist, da die Düse wesentlich langsamer bzw. nicht mehr verrußt. Hierdurch werden die Wartungskosten für das System gesenkt, da das Wartungsintervall des Brenners im wesentlichen durch die Funktionsfähigkeit der Düse bestimmt wird. Ein langsameres Verrußen der Düse bedeutet daher niedrigere Wartungskosten.During the breaks in operation, the nozzle is advantageously positioned so that it is no longer in alignment with the window-like opening, but is separated or shielded from a wall, in particular the burner chamber wall, from the burner chamber. This prevents contamination or sooting of the nozzle during the breaks in operation and on the other hand, the nozzle is protected from thermal stress, which significantly increases the system security and the service life of the nozzle and additionally ensures constant burner output, since the nozzle is much slower or no longer sooty. As a result, the maintenance costs for the system are reduced, since the maintenance interval of the burner is essentially determined by the functionality of the nozzle. Slower soot fouling therefore means lower maintenance costs.

Ebenfalls vorteilsmäßig ist es, wenn in der zweiten Position ein mit der Düse verschwenkbares Teil die fensterartige Öffnung der begrenzenden Wand abdichtend verschließt. Hierdurch ist während der Betriebspausen des Brenners gewährleistet, daß keine im Brennerraum befindlichen Gase aus dem Brennerraum durch die fensterartige Öffnung austreten können.It is also advantageous if in the second position a part that can be pivoted with the nozzle seals the window-like opening of the delimiting wall. This ensures during the breaks in operation of the burner that no gases in the burner chamber can escape from the burner chamber through the window-like opening.

Auch ist es von Vorteil, wenn in der ersten Position ein Düsenhalter an der den Brennerraum begrenzenden Wand anliegt und für die fluchtend vor der fensterartigen Öffnung befindliche Düse einen lediglich mit dem Brennerraum verbundenen Raum bildet. Es ist somit stets gewährleistet, daß der von der Düse austretende Brennstoff bzw. das Verbrennungsgemisch nur in den Brennerraum gelangt. Hierdurch wird der für die Düse benötigte Raum lediglich durch die Abmessungen des Düsenhalters bestimmt. Es läßt sich somit der benötigte Raum vorteilsmäßig verkleinern. Die Düse ist dabei bevorzugt an dem Düsenhalter direkt befestigt.It is also advantageous if, in the first position, a nozzle holder rests on the wall delimiting the burner chamber and forms a space that is only connected to the burner chamber for the nozzle that is aligned in front of the window-like opening. It is thus always ensured that the fuel emerging from the nozzle or the combustion mixture only reaches the burner chamber. As a result, the space required for the nozzle is determined only by the dimensions of the nozzle holder. The space required can thus advantageously be reduced. The nozzle is preferably attached directly to the nozzle holder.

In der zweiten Position bildet der Düsenhalter zusammen mit der begrenzenden Wand einen abgeschlossenen Raum, in dem die Düse angeordnet ist, wodurch die Düse während der Betriebspausen des Brenners vor Verschmutzung sicher geschützt ist.In the second position, the nozzle holder forms, together with the delimiting wall, an enclosed space in which the nozzle is arranged, as a result of which the nozzle is reliably protected against contamination during the burner's pauses in operation.

Um eine besonders gute Abdichtung zwischen dem Düsenhalter und der begrenzenden Wand zu erhalten, ist vorteilsmäßig mindestens eine Dichtung, die insbesondere von einem am Düsenhalter befestigten Dichtungshalter gehalten ist, zwischen der begrenzenden Wand und dem Düsenhalter oder dem Dichtungshalter. Der Dichtungshalter umschließt die Düse in radialer Richtung, wodurch vom Dichtungshalter eine Wand gebildet wird, die etwas höher ist als die Düse, wodurch sich ein geringer Abstand zwischen Düsenvorderseite und der begrenzenden Wand des Brennerraums ergibt.In order to obtain a particularly good seal between the nozzle holder and the delimiting wall, at least one seal, which is held in particular by a seal holder attached to the nozzle holder, is advantageously between the delimiting wall and the nozzle holder or the seal holder. The seal holder encloses the nozzle in the radial direction, whereby a wall is formed by the seal holder that is slightly higher than the nozzle, which results in a small distance between the front of the nozzle and the delimiting wall of the burner chamber.

In einer bevorzugten Ausführungsform ist der Düsenhalter mittels eines Lagers an der begrenzenden Wand verschiebbar oder verschwenkbar gelagert und mittels eines Stellantriebs von der einen Position in die andere Position verschiebbar oder verschwenkbar. Das Lager besteht dabei aus einem an dem Brennergehäuse befestigten oder angeformten runden, insbesondere zylindrischen Teil, welches in einer runden Aussparung des Düsenhalters einliegt. Ein derartiges Lager ist besonders temperaturunabhängig und funktioniert auch bei Verschmutzung. Ein Festsetzen des Lager wird somit vermieden, wodurch die Funktionssicherheit des Systems hoch ist.In a preferred embodiment, the nozzle holder is mounted displaceably or pivotably on the limiting wall by means of a bearing and can be displaced or pivoted from one position to the other position by means of an actuator. The bearing consists of a round, in particular cylindrical, part which is fastened or molded onto the burner housing and which lies in a round recess in the nozzle holder. Such a bearing is particularly temperature-independent and also works when it is dirty. This prevents the bearing from becoming stuck, as a result of which the functional reliability of the system is high.

Die der Erfindung zugrunde liegende Aufgabe wird erfindungsgemäß auch dadurch gelöst, wenn auf einem Düsenhalter mehrere Düsen angeordnet sind, die mittels eines Stellantriebs jeweils fluchtend vor die fensterartige Öffnung der den Brennerraum begrenzenden Wand bewegbar sind. Der Düsenhalter ist hierzu mittels eines Lagers am Brennergehäuse beweglich gelagert, und die Düsen sind auf einem insbesondere kreisförmigen Bogen um das Lager angeordnet. Der Düsenhalter liegt an der den Brennerraum begrenzenden Wand an und bildet für die jeweils fluchtend vor der fensterartigen Öffnung befindliche Düse einen lediglich mit dem Brennerraum verbundenen Raum.The object on which the invention is based is also achieved according to the invention if a plurality of nozzles are arranged on a nozzle holder and can be moved in alignment with the window-like opening of the wall delimiting the burner chamber by means of an actuator. For this purpose, the nozzle holder is movably mounted on the burner housing by means of a bearing, and the nozzles are arranged on an especially circular arc around the bearing. The nozzle holder lies against the wall delimiting the burner chamber and forms a space which is only connected to the burner chamber for the nozzle which is in each case in alignment with the window-like opening.

Zusätzlich kann vorteilsmäßig zwischen dem Düsenhalter und der begrenzenden Wand ein Dichtungselement und/oder ein Dichtungselementehalter angeordnet sein, das bzw. der am Düsenhalter befestigt ist und mit dem Düsenhalter bewegbar ist, wobei der Düsenhalter zusammen mit dem Dichtungselement und/oder Dichtungselementehalter und der begrenzenden Wand für die jeweils fluchtend vor der fensterartigen Öffnung befindliche Düse einen lediglich mit dem Brennerraum verbundenen Raum bildet.In addition, a sealing element and / or a sealing element holder can be advantageously arranged between the nozzle holder and the delimiting wall, which is attached to the nozzle holder and is movable with the nozzle holder, the nozzle holder together with the sealing element and / or sealing element holder and the delimiting wall For the nozzle in alignment in front of the window-like opening forms a space which is only connected to the burner chamber.

Der Dichtungselementehalter ist dabei vorzugsweise derart ausgebildet, daß jede Düse jeweils in einer fensterartigen Öffnung des Dichtungselementehalters einliegt.The sealing element holder is preferably designed such that each nozzle lies in a window-like opening of the sealing element holder.

Durch den Einsatz von mehreren Düsen kann vorteilshaft ein automatischer Wechsel der Düsen vorgenommen werden, sobald eine Düse verstopft bzw. verrußt ist. Dies kann z.B. nach einer bestimmten vorgebbaren Betriebsdauer automatisch geschehen oder es werden Sensoren vorgesehen, die den Wirkungsgrad der Verbrennung des Brenners messen. Sobald der Wirkungsgrad sich unter einen vorgebbaren Wert verschlechtert, kann ein Wechsel vorgenommen werden.By using several nozzles, an automatic change of the nozzles can advantageously be carried out as soon as a nozzle is blocked or sooty. This can e.g. happen automatically after a certain predeterminable operating time or sensors are provided which measure the efficiency of the combustion of the burner. As soon as the efficiency deteriorates below a predeterminable value, a change can be made.

Ein weiterer Vorteil beim Einsatz von mehreren Düsen ist, daß Düsen verschiedener Größe einsetzbar sind, mit denen sich eine Leistungsregelung des Brenners erzielen läßt.Another advantage of using several nozzles is that nozzles of different sizes can be used with which burner output control can be achieved.

Der Düsenhalter ist vorteilsmäßig bei allen Ausführungsformen manuell mittels eines Hebels oder mittels eines pneumatisch oder elektrisch betriebenen Stellantriebs verschieb- oder verschwenkbar. Dazu hat der Stellantrieb Signalgeber, die einer Steuerung des Stellantriebs die Position bzw. Lage des Düsenhalter bzw. der Düse(n) übermitteln.In all embodiments, the nozzle holder can advantageously be displaced or pivoted manually by means of a lever or by means of a pneumatically or electrically operated actuator. For this purpose, the actuator has signal transmitters which transmit the position or position of the nozzle holder or the nozzle (s) to a control of the actuator.

Die gestellte Aufgabe wird zudem erfindungsgemäß dadurch gelöst, daß die fensterartige Öffnung mittels eines Schiebers verschließbar ist, wobei der Schieber die Düse vom Brennerraum abschirmt. Ein Verschwenken oder Verschieben der Düse samt Halterung ist in diesem Fall unnötig. Es muß lediglich der Schieber bewegt werden, wodurch lediglich ein kleiner Antrieb erforderlich ist. Der Schieber ist dabei manuell oder mittels eines pneumatischen oder elektrischen Stellantriebes verschieb- oder verschwenkbar. Vorteilsmäßig ist der Schieber dazu mittels eines Lagers am Brennergehäuse gelagert.The object is also achieved according to the invention in that the window-like opening can be closed by means of a slide, the slide shielding the nozzle from the burner chamber. In this case, swiveling or moving the nozzle together with the holder is unnecessary. Only the slide has to be moved, which means that only a small drive is required. The slide can be moved or swiveled manually or by means of a pneumatic or electric actuator. For this purpose, the slide is advantageously mounted on the burner housing by means of a bearing.

Die fensterartige Öffnung kann in einer weiteren möglichen Ausführungsform mittels mindestens eines biegsamen Dichtungsteils verschlossen sein. Das biegsame Dichtungsteil öffnet die fensterartige Öffnung nur dann, wenn durch die Düse Brennstoff, Luft oder Verbrennungsgemisch strömt, wobei das strömende Medium die Laschen des biegsamen Teils in Richtung des Brennerraums umbiegt. Der Brennstoff oder das Verbrennungsgemisch kann dann ungehindert in den Brennerraum strömen.In a further possible embodiment, the window-like opening can be closed by means of at least one flexible sealing part. The flexible sealing part opens the window-like opening only when fuel, air or combustion mixture flows through the nozzle, the flowing medium bending the tabs of the flexible part in the direction of the burner chamber. The fuel or the combustion mixture can then flow freely into the burner chamber.

Wird die Brennstoff- oder Verbrennungsgemischzufuhr gestoppt, so kehren die Teile insbesondere Laschen des Dichtungsteils in ihre Ausgangslage zurück und verschließen die fensterartige Öffnung, wodurch keine Ruß oder Gas mehr aus dem Brennerraum austreten kann.If the fuel or combustion mixture supply is stopped, the parts, in particular tabs of the sealing part, return to their starting position and close the window-like opening, as a result of which no more soot or gas can escape from the burner chamber.

Im folgenden wird anhand von möglichen Ausführungsformen die Erfindung näher erläutert.The invention is explained in more detail below on the basis of possible embodiments.

Figur 1a zeigt einen Brenner mit einem Brennerraum 1, der durch das Brennergehäuse 2 begrenzt ist. Das Brennergehäuse 2 hat an einer Wand 2a eine fensterartige Öffnung, durch die eine Düse 3 Brennstoff oder ein Verbrennungsgemische 4 einspritzt. Die Düse 3 ist an einem Düsenhalter 6 befestigt, welcher mittels des Lagers 8 an dem Brennergehäuse 2 oder an der begrenzenden Wand 2a des Brennergehäuses 2 verschwenkbar gelagert ist.Figure 1a shows a burner with a burner chamber 1, which is limited by the burner housing 2. The burner housing 2 has a window-like opening on a wall 2a through which a nozzle 3 injects fuel or a combustion mixture 4. The nozzle 3 is fastened to a nozzle holder 6 which is pivotably mounted on the burner housing 2 or on the delimiting wall 2a of the burner housing 2 by means of the bearing 8.

Am Düsenhalter 6 ist ein Dichtungsträger 7 befestigt. Der Dichtungshalter 7 umgibt die Düse 3 in radialer Richtung und bildet zusammen mit dem Düsenhalter 6 einen Düsenraum 13, in dem die Düse 3 ist. Der Dichtungshalter 7 hat an seiner der begrenzenden Wand 2a zugewandten Seite nicht dargestellte Nuten, in denen Dichtungsringe 7a einliegen und den Düsenraum 13 nach außen hin abdichtet. Der Düsenraum 13 ist lediglich in der ersten Position, d.h., wenn die Düse 3 fluchtend vor der fensterartigen Öffnung 5 positioniert ist, mit dem Brennerraum 1 in Verbindung.A seal carrier 7 is attached to the nozzle holder 6. The seal holder 7 surrounds the nozzle 3 in the radial direction and, together with the nozzle holder 6, forms a nozzle space 13 in which the nozzle 3 is. The seal holder 7 has on its side facing the delimiting wall 2a grooves, not shown, in which sealing rings 7a lie and seal the nozzle space 13 from the outside. The nozzle chamber 13 is only in the first position, i.e. when the nozzle 3 is positioned in alignment with the window-like opening 5, in connection with the burner chamber 1.

Der Düse 3 wird über eine Brennstoffzuleitung 9 der Brennstoff zugeführt. Über eine weitere Zuleitung 10 kann der Düse 3 und/oder dem Düsenraum 13 Luft oder ein anderes Gas zugeführt werden.The fuel is supplied to the nozzle 3 via a fuel feed line 9. Via a further feed line 10, the nozzle 3 and / or air or another gas are supplied to the nozzle chamber 13.

Figur 1b zeigt eine Draufsicht auf die Unterseite eines Brenners, wobei der Düsenhalter 6 über ein Gelenk 6a mit einem Stellantrieb 11 in Verbindung ist. Mittels des Stellantriebs 11 kann der Düsenhalter 6 mit Düse 3 und Dichtungshalter 7 von einer ersten (Fig.1b) in eine zweite (Fig.1c) Position verschwenkt werden. In der ersten Position ist der Düsenraum 13 mit dem Brennerraum 1 in Verbindung. In der zweiten Position verschließt der Dichtungshalter 7 mittels der Dichtungen 7a die fensterartige Öffnung 5, so daß keine Gase aus dem Brennerraum 1 austreten können. Gleichzeitig wird die Düse 3 von der begrenzenden Wand 2a vom Brennerraum 1 abgeschirmt.FIG. 1b shows a plan view of the underside of a burner, the nozzle holder 6 being connected to an actuator 11 via a joint 6a. By means of the actuator 11, the nozzle holder 6 with nozzle 3 and seal holder 7 can be pivoted from a first (FIG. 1b) to a second (FIG. 1c) position. In the first position, the nozzle chamber 13 is connected to the burner chamber 1. In the second position, the seal holder 7 closes the window-like opening 5 by means of the seals 7a, so that no gases can escape from the burner chamber 1. At the same time, the nozzle 3 is shielded by the delimiting wall 2a from the burner chamber 1.

In den Figuren 2a, 2b und 2c ist ein Brenner dargestellt, bei dem zwischen der Düse 3 und dem Brennerraum 1 ein Schieber 12 angeordnet ist. der Schieber 12 ist ein im wesentlichen flaches Teil, welches eine fensterartige Öffnung 12a hat. Der Schieber 12 ist mittels eines nicht dargestellten Stellantriebs beweglich zwischen der begrenzenden Wand 2a und der Düse 3 gelagert. In einer ersten Position (Fig.2a) fluchten die fensterartigen Öffnungen 5 und 12a des Brennergehäuses 2 und des Schiebers 12, wodurch der Brennerraum 1 mit dem Düsenraum 13 in Verbindung ist und Brennstoff 4 von der Düse 3 in den Brennerraum 1 gelangen kann.FIGS. 2a, 2b and 2c show a burner in which a slide 12 is arranged between the nozzle 3 and the burner chamber 1. the slider 12 is a substantially flat part which has a window-like opening 12a. The slide 12 is movably mounted between the limiting wall 2a and the nozzle 3 by means of an actuator, not shown. In a first position (FIG. 2a), the window-like openings 5 and 12a of the burner housing 2 and the slide 12 are aligned, as a result of which the burner chamber 1 is connected to the nozzle chamber 13 and fuel 4 can get from the nozzle 3 into the burner chamber 1.

In einer zweiten Position (Fig.2b) ist der Schieber 12 derart verschoben, daß die Fensterartige Öffnung 5 der begrenzenden Wand vom Schieber 12 verschlossen ist. Der Düsenraum 13 ist jetzt vom Brennerraum 1 getrennt und es können keine Gase oder Ruß aus dem Brennerraum 1 zur Düse gelangen.In a second position (FIG. 2b), the slide 12 is displaced such that the window-like opening 5 of the delimiting wall is closed by the slide 12. The nozzle chamber 13 is now separated from the burner chamber 1 and no gases or soot can get from the burner chamber 1 to the nozzle.

Die Figuren 3a und 3b Zeigen ebenfalls einen Brenner mit einem Brennerraum 1 und einer vor einer fensterartigen Öffnung 5 befestigten Düse 3. In oder vor der fensterartigen Öffnung 5 der begrenzenden Wand 2a ist ein Dichtungsteil 14 angeordnet, welches biegsam ausgebildet ist und das während der Betriebspausen des Brenners (Fig.3a), d.h., wenn kein Gas oder Öl vom Düsenraum 13 in den Brennerraum 1 gefördert wird, die fensterartige Öffnung 5 abdichtend verschließt.
Wird wie in Figur 3b dargestellt ein Verbrennungsgemisch 4 aus dem Düsenraum 13 in Richtung der durch das biegsame Dichtungsteil 14 verschlossenen fensterartigen Öffnung 5 gefördert, so wird das Dichtungsteil 14 aufgebogen und der Düsenraum 13 ist mit dem Brennerraum 1 in Verbindung.Figures 3a and 3b also show a burner with a burner chamber 1 and a nozzle 3 attached in front of a window-like opening 5. In or in front of the window-like opening 5 of the delimiting wall 2a, a sealing part 14 is arranged, which is designed to be flexible and that during the Pauses in operation of the burner (FIG. 3a), ie, if no gas or oil is conveyed from the nozzle chamber 13 into the burner chamber 1, seals the window-like opening 5 in a sealing manner.
If, as shown in FIG. 3b, a combustion mixture 4 is conveyed out of the nozzle chamber 13 in the direction of the window-like opening 5 closed by the flexible sealing part 14, the sealing part 14 is bent open and the nozzle chamber 13 is connected to the burner chamber 1.

Das Dichtungsteil 14 kann auch Klappen aufweisen, die mittels Federn in ihre Schließposition bringbar sind. Die Klappen sind dabei an dem Brennergehäuse 2 oder dem Rand der fensterartigen Öffnung 5 beweglich gelagert.The sealing part 14 can also have flaps which can be brought into their closed position by means of springs. The flaps are movably mounted on the burner housing 2 or the edge of the window-like opening 5.
