Description

Stand der TechnikState of the art

Die Erfindung betrifft einen Gasbrenner mit einem Basisteil, das eine Gaszuführung aufweist und auf dem ein Lamellenblock abgedichtet befestigbar ist, wobei der Lamellenblock aus parallel zueinander stehenden Lamellen gebildet ist, aus denen Wärme mittels Kühlelementen auskoppelbar ist, und wobei der Lamellenblock von einem Rahmen umgeben ist, der die in Strömungsrichtung des Brenngases verlaufenden Seiten des Lamellenblock zumindest teilweise überdeckt.The invention relates to a gas burner with a base part, the one Has gas supply and on which a lamellar block can be sealed is, the slat block formed from mutually parallel slats is, from which heat can be coupled out by means of cooling elements, and wherein the Lamellar block is surrounded by a frame which is in the direction of flow of the fuel gas extending sides of the lamella block at least partially covered.

Bei solchen Gasbrennern bilden der Lamellenblock und der Rahmen eine Einheit. Diese wird unter Zwischenlage einer Dichtung auf das Basisteil aufgesetzt. Die Dichtung verhindert dabei, daß Brenngas unkontrolliert entweichen und sich entzünden kann, Infolge der Verbrennung an der flammseitigen Oberfläche des Lamellenblock wird Wärme in den Rahmen eingeleitet. Hierdurch kann es zu einer sehr starken Erwärmung kommen, wodurch die Dichtung thermisch belastet wird. Damit können nur hochtemperaturfeste Dichtmaterialien Verwendung finden. Aufgrund von thermischen Verformungen des Rahmens infolge von Temperaturschwankungen beim Verbrennungsprozeß muß die Dichtung entsprechende Ausgleichseigenschaften aufweisen. Eine Dichtung, die den gestellten Anforderungen entspricht ist aufwendig und entsprechend teuer herzustellen.In such gas burners, the lamella block and the frame form a unit. This is placed on the base part with the interposition of a seal. The Sealing prevents fuel gas from escaping in an uncontrolled manner can ignite due to combustion on the flame-side surface of the Lamella block is heat introduced into the frame. This can cause it to a very strong heating, which causes thermal stress on the seal becomes. This means that only high-temperature resistant sealing materials can be used Find. Due to thermal deformation of the frame as a result of temperature fluctuations in the combustion process, the seal must be appropriate Have balancing properties. A seal that the the requirements are complex and correspondingly expensive to manufacture.

Es ist Aufgabe der Erfindung, einen Gasbrenner der eingangs erwähnten Art zu schaffen, bei dem der Rahmen gegenüber dem Basisteil auf einfache Weise abgedichtet werden kann.It is an object of the invention to a gas burner of the type mentioned create, in which the frame sealed against the base part in a simple manner can be.

Diese Aufgabe wird dadurch gelöst, daß zumindest ein Teil der Lamellen mittels Wärmebrücken an den Rahmen angeschlossen sind.This object is achieved in that at least part of the slats by means of Thermal bridges are connected to the frame.

Mit dieser einfachen konstruktiven Maßnahme wird sichergestellt, daß die Wärme aus dem Rahmen über die Wärmebrücken und die gekühlten Lamellen ausgekoppelt werden kann. Damit lassen sich die Temperaturen im Dichtungsbereich erheblich reduzieren. Dies ermöglicht den Rückgriff auf konventionelle Dichtmaterialien. Dadurch, daß der Rahmen mittels der Wärmebrücken und der Lamellen auf einem etwa konstanten Temperaturniveau gehalten ist, sind thermische Verformungen weitgehend verhindert.This simple constructive measure ensures that the Heat from the frame via the thermal bridges and the cooled slats can be coupled out. This allows the temperatures in the sealing area reduce significantly. This enables the use of conventional ones Sealing materials. The fact that the frame by means of the thermal bridges and Slats are kept at an approximately constant temperature level largely prevents thermal deformation.

Zur Auskopplung der Wärme aus dem Rahmen kann es vorgesehen sein, daß die Lamellen stoffschlüssig an den Rahmen angeschlossen sind, wobei die Wärmebrücken als Schweißnaht oder als Lötung ausgebildet sind.To extract the heat from the frame, it can be provided that the Slats are integrally connected to the frame, the thermal bridges are designed as a weld seam or as soldering.

Die Lamellen können aus rechteckigen Stanz-Biegeteilen geformt sein, die mit ihren Schmalseiten an den Rahmen über die Wärmebrücken angebunden sind. The lamellae can be formed from rectangular stamped and bent parts, which with their narrow sides are connected to the frame via the thermal bridges.

Eine einfache konstruktive Ausgestaltung des Rahmens ist dann gegeben, wenn er zwei rechtwinklig zueinanderstehende Schenkel aufweist, von denen der eine auf dem Basisteil aufsitzt und in Wirkverbindung mit der Dichtung steht und der zweite Schenkel über die Wärmebrücken an die Lamellen angeschlossen ist. Die Dichtung kann mit dem ersten Schenkel flächig beaufschlagt werden. Dadurch, daß der erste Schenkel gegenüber dem zweiten Schenkel rechtwinklig abgekantet ist, kann die Dichtung beabstandet von dem Lamellenblock gehalten werden. Damit wird der Einfluß von Wärmestrahlungen erheblich reduziert.A simple structural design of the frame is given if he has two legs at right angles to each other, one of which sits on the base part and is in operative connection with the seal and the second leg is connected to the slats via the thermal bridges. The The first leg can be applied to the surface of the seal. Thereby, that the first leg is bent at right angles to the second leg the seal can be held spaced from the lamella block become. This significantly reduces the influence of heat radiation.

Eine bevorzugte Erfindungsvariante sieht vor, daß der Rahmen einen Kragen trägt, der im Bereich der Flammenseite des Lamellenblocks angeordnet ist und diesen überragt, und daß der Kragen über eine Dehnverbindung mit dem Rahmen verbunden ist. Dadurch, daß der Rahmen über die Flammenseite des Lamellenblocks vorragt, wird eine Stabilisierung der Flammen erreicht. Infolge dieser Anordnung wird jedoch ein hoher Anteil von Wärmestrahlung in den Kragen eingebracht. Dieser kann zu thermischen Verformungen des Kragens führen. Da nun aber eine Dehnverbindung zwischen dem Kragen und dem Rahmen vorgesehen ist, werden die thermischen Verformungen nicht in den Rahmen übertragen.A preferred variant of the invention provides that the frame has a collar carries, which is arranged in the region of the flame side of the slat block and this protrudes, and that the collar via an expansion joint with the frame connected is. The fact that the frame over the flame side of the slat block protrudes, the flames are stabilized. As a result of this However, the arrangement introduces a high proportion of heat radiation into the collar. This can lead to thermal deformation of the collar. There but now an expansion joint is provided between the collar and the frame the thermal deformations are not transferred into the frame.

Die Erfindung wird im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.The invention is described below with reference to one in the drawing Embodiment explained in more detail.

In dem einzigen Figurenblatt ist ein Gasbrenner in Seitenansicht und im Schnitt dargestellt. Der Gasbrenner weist ein Basisteil 10 auf, das von einem Kanalsystem durchzogen ist. Dieses Kanalsystem dient als Gaszuführung 11. Dabei wird Brenngas über eine Injektoranordnung 11a in die Gaszuführung 11 eingeleitet. Das Brenngas strömt einem Lamellenblock 30 zu. Der Lamellenblock 30 ist quaderförmig ausgebildet und weist eine Vielzahl von parallel zueinanderstehenden, in der Bildebene hintereinander liegenden Lamellen 31 auf. Die Lamellen 31 sind mit kreisrunden Durchbrüchen versehen, durch die Kühlrohre 31 gefädelt sind. Über die Kühlrohre 32 kann Wärme aus den Lamellen 31 ausgekoppelt werden. Der Lamellenblock 30 ist allseitig von einem Rahmen 20 umgeben. Der Rahmen 20 liegt dabei mit einem Schenkel 22 an der jeweils zugeordneten Seite des Lamellenblocks 30 an. Von dem Schenkel 22 ist ein weiterer Schenkel 21 horizontal abgewinkelt. Der weitere Schenkel 21 liegt flanschartig auf einem Stützabschnitt 12 des Basisteils auf. Der Schenkel 21 stützt sich dabei auf einer Dichtung 13 ab, die in einer Nut des Basisteiles 10 aufgenommen ist. Der Schenkel 21 geht in einen Halteabschnitt 27 über, der von dem Schenkel 21 abgebogen ist und aufwärts gerichtet absteht. Die Lamellen 31 sind an den Schenkel 22 des Rahmens 20 über Wärmebrücken 24 angekoppelt. In der Zeichnung sind zwei Alternativmöglichkeiten zur Anbringung der Wärmebrücken 24 gezeigt. Zum einen ist an der Unterseite des Lamellenblocks 30 eine Schweißverbindung in Form einer Kehlnaht aufgebracht. Andererseits ist es jedoch auch möglich, von der Außenseite des Schenkels 22 her auf die Lamelle 31 durchzuschweißen. Eine weitere Möglichkeit der Herstellung einer Wärmebrücke besteht darin, daß auf die stirnseitigen Enden der Lamellen 31 ein Lot aufgebracht ist, das eine stoffschlüssige Verbindung zu dem Rahmen 20 herstellt.In the single figure sheet is a gas burner in side view and in section shown. The gas burner has a base part 10, which is a duct system is crossed. This channel system serves as a gas supply 11 fuel gas is introduced into the gas supply 11 via an injector arrangement 11a. The fuel gas flows to a lamella block 30. The slat block 30 is cuboid and has a large number of mutually parallel, in the image plane one behind the other slats 31. The Lamellas 31 are provided with circular openings through the cooling tubes 31 are threaded. Heat can be extracted from the fins 31 via the cooling tubes 32 become. The lamella block 30 is surrounded on all sides by a frame 20 surround. The frame 20 lies with one leg 22 on the respectively assigned one Side of the slat block 30. Another of the legs 22 Leg 21 angled horizontally. The other leg 21 lies flange-like on a support section 12 of the base part. The leg 21 is supported on a seal 13 which is in a groove in the base part 10 is recorded. The leg 21 merges into a holding section 27 which is bent from the leg 21 and protrudes upward. The slats 31 are coupled to the legs 22 of the frame 20 via thermal bridges 24. In the drawing there are two alternative options for attachment of the thermal bridges 24 shown. Firstly, on the underside of the slat block 30 applied a welded joint in the form of a fillet weld. On the other hand it is also possible, however, from the outside of the leg 22 to be welded to the lamella 31. Another way of making A thermal bridge consists in that on the front ends of the slats 31 a solder is applied, which is a material connection to the frame 20 manufactures.

Auf den Rahmen 20 ist ein Kragen 23 aufgesetzt. Zur Ankopplung des Kragens 23 an den Rahmen 20 ist eine Dehnverbindung 28 vorgesehen. Der Kragen 23 geht im Anschluß an die Dehnverbindung 28 in eine horizontale Abkantung 25 über. An die Abkantung 25 schließt sich ein Stützabschnitt 26 an. Wenn der Kragen 23 auf den Rahmen 20 aufgesetzt ist, kommt der Stützabschnitt 26 mit dem Halteabschnitt 27 in Deckung. In dieser Montagestellung kann dann der Stützabschnitt 26 mit dem Halteabschnitt 27 unter Zuhilfenahme des Dehnelementes 28 verbunden werden.A collar 23 is placed on the frame 20. For coupling the collar 23 an expansion connection 28 is provided on the frame 20. The collar 23 goes into a horizontal bend 25 following the expansion joint 28 about. A support section 26 adjoins the fold 25. If the Collar 23 is placed on the frame 20, the support portion 26 comes with the holding section 27 in cover. In this assembly position, the Support section 26 with the holding section 27 with the aid of the expansion element 28 are connected.

Der Lamellenblock 30 kann an dem Basisteil 10 mittels Verschlüssen 14 fixiert werden.The lamella block 30 can be fixed to the base part 10 by means of closures 14 become.

Im Betrieb wird Brenngas durch die Gaszuführung 11 des Basisteils 10 geleitet. Dieses strömt zwischen den einzelnen Lamellen 31 durch den Lamellenblock 30 hindurch. Dort wird es mittels einer Zündung 33 entzündet. Hierdurch entsteht eine Flammenfront, die sich über die gesamte Oberfläche des Lamellenblocks 30 erstreckt. Die bei der Verbrennung entstehende Strahlungswärme wird teilweise in den Kragen 23 eingeleitet. Von hier überträgt sie sich auf den Schenkel 22 des Rahmens 20. Die Wärme wird von dem Schenkel 22 größtenteils wieder über die Wärmebrücken 24 in die gekühlten Lamellen 31 zurückgeleitet. Dadurch kann der Schenkel 22 weitgehend von Wärmeeinflüssen freigehalten werden, so daß auch schädliche Temperatureinflüsse von der Dichtung 13 ferngehalten werden können.In operation, fuel gas is passed through the gas supply 11 of the base part 10. This flows between the individual slats 31 through the slat block 30 through it. There it is ignited by means of an ignition 33. This creates a flame front that extends over the entire surface of the lamella block 30 extends. The radiant heat generated during combustion is partially introduced into the collar 23. From here it is transferred to the leg 22 of the frame 20. The heat is largely from the leg 22 again passed back over the thermal bridges 24 into the cooled fins 31. Thereby the leg 22 can be kept largely free from the effects of heat, so that harmful temperature influences are kept away from the seal 13 can be.
