Description

Die Erfindung betrifft einen Brenner für ein Brennstoffgemisch aus Luft und Gas, bei dem das Brennstoffgemisch mittels einer Armatur einem in einer Brennkammer angeordneten Brennerelement zuführbar ist und bei dem die bei der Verbrennung entstehenden Abgase über einen Wärmeübertrager, eine Abgaskammer und einer Abgasführung ableitbar sind.The invention relates to a burner for a fuel mixture of air and gas, wherein the fuel mixture can be supplied by means of a valve arranged in a combustion chamber burner element and in which the resulting exhaust gases during combustion via a heat exchanger, an exhaust chamber and an exhaust system are derivable.

Stand der TechnikState of the art

Bei den Brennern dieser Art treten insbesondere bei der Flammenstabilität und der Abführung der Abgase Probleme auf. Dabei beeinflussen Maßnahmen zur Verbeserung in der einen oder anderen Problemzone das Kaltstartverhalten, die Emissionen und damit den Wirkungsgrad des Brenners.In the burners of this type occur in particular in the flame stability and the discharge of the exhaust gases problems. Here, measures to improve in one or the other problem zone affect the cold start behavior, the emissions and thus the efficiency of the burner.

Die EP 0 655 579 A zeigt ein Heizgerät mit gebläseunterstützter Verbrennung, das eine Vorrichtung zur Flammenstabilisierung aufweist. Hierzu wird der Verbrennungsluftstrom mittels abschirmender Wände rund um die Brenneroberfläche zumindest teilweise vom Gas-Luft-Gemischstrom und von der Flammenzone entkoppelt.The EP 0 655 579 A shows a fan assisted combustion heater having a device for flame stabilization. For this purpose, the combustion air flow is at least partially decoupled from the gas-air mixture flow and from the flame zone by means of shielding walls around the burner surface.

Eine Strömungsentkopplung zeigt auch die US 6 082 993 A , wobei hier die in die Zone der Gas-Luft-Gemischaufbereitung einströmende Verbrennungsluft durch eine blendenähnliche Vorrichtung von der den Brenner umgebenden Luft abgekoppelt wird.A flow decoupling also shows the US Pat. No. 6,082,993 A , Here, the combustion air flowing into the zone of the gas-air mixture preparation combustion air is decoupled by an aperture-like device of the air surrounding the burner.

Es ist Aufgabe der Erfindung, einen Brenner der eingangs erwähnten Art so zu gestalten, dass die Flammenstabilität und die Abführung des Abgases verbessert wird, ohne das Kaltstartverhalten und die Emissionswerte zu verschlechtern.It is an object of the invention to design a burner of the type mentioned above so that the flame stability and the discharge of the exhaust gas is improved, without deteriorating the cold start behavior and the emission values.

Vorteile der ErfindungAdvantages of the invention

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass die aus dem Wärmeübertrager austretenden Abgase über einen Abgassammler gesammelten und über ein Labyrinth mit Leitblechen geführt einem nachgeordneten Gebläse zuführbar sind und dass der Ausgang des Gebläses mit der Abgasführung gekoppelt ist.This object is achieved according to the invention in that the exiting from the heat exchanger exhaust gases collected through an exhaust manifold and guided over a labyrinth with baffles a downstream fan can be fed and that the output of the fan is coupled to the exhaust system.

Mit dem Labrinth wird eine Entkopplung zwischen dem nachgeordneten Gebläse und dem Wärmeüberträger und damit der Flamme vor dem Wärmeübertrager erreicht. Das Flammenbild wird trotz Abführung des Abgases mittels des Gebläses gleichmäßiger, was mit einer Verbesserung der Emissionswerte verbunden ist. Das Gebläse sorgt für eine eindeutige Abführung des Abgases und kann mit dem Gebläse angepasst und ausreichend effektiv eingestellt werden. Das Labyrinth mit den Leiterblechen wirkt dabei zur Wärmeübertragung und Flamme hin als Zugunterbrechung und als gezielte Führug des Abgases zum Gebläse hin.With the Labrinth decoupling between the downstream fan and the heat exchanger and thus the flame is achieved in front of the heat exchanger. The flame pattern is more uniform despite the discharge of the exhaust gas by means of the blower, which is associated with an improvement of the emission values. The blower ensures a clear discharge of the exhaust gas and can be adjusted with the blower and adjusted sufficiently effectively. The labyrinth with the PCBs acts to heat transfer and flame out as train interruption and as a targeted guidance of the exhaust gas to the blower.

Nach einer vorteilhaften Ausgestaltung ist vorgesehen, dass der Abgassammler eine Eintrittsöffnung aufweist, die die Austrittsöffnungen des Wärmeübertragers vollständig überdeckt und dass die im Querschnitt verkleinerte Austrittsöffnung des Abgassammlers mit der Eingangsöffnung des Labyrinths gekoppelt ist. Auf diese Weise wird das den Wärmeübertrager verlassende Abgas in seiner Gesamtheit erfasst und gezielt geführt dem Labyrinth zugeführt.According to an advantageous embodiment, it is provided that the exhaust gas collector has an inlet opening which completely covers the outlet openings of the heat exchanger and that the reduced outlet opening in cross-section of the exhaust collector is coupled to the input opening of the labyrinth. In this way, the exhaust gas leaving the heat exchanger is detected in its entirety and fed specifically guided the labyrinth.

Das Labyrinth ist vorzugsweise so ausgebildet, dass das Labyrinth durch abwechselnd gegeneinander gerichtete Leitbleche gebildet ist, die am Labyrinth-Gehäuse angebracht und horizontal ausgerichtet sind.The labyrinth is preferably designed so that the labyrinth is formed by alternately directed baffles, which are mounted on the labyrinth housing and aligned horizontally.

Damit das Gebläse das zugeführte Abgas in einfacher Weise an die Abgasführung weiterleiten kann, sieht eine weitere Ausgestaltung vor, dass der Ausgang des Labyrinths mit einem axialen Eingang des Gebläses und ein radialer Ausgang des Gebläses mit der Abgasführung verbunden sind.So that the blower can forward the supplied exhaust gas in a simple manner to the exhaust gas duct, a further embodiment provides that the outlet of the labyrinth be connected to an axial inlet of the blower and a radial outlet of the blower to the exhaust duct.

Die Führung des Abgases im Labyrinth erfolgt nach einer Ausgestaltung in der Weise, dass es vertikal geführt in das Labyrinth eintritt und dieses horizontal geführt verläßt.The leadership of the exhaust gas in the labyrinth takes place according to an embodiment in such a way that it enters the labyrinth led vertically and leaves this led horizontally.

Ist nach einer Ausgestaltung vorgesehen, dass das dem Gebläse zugekehrte letzte Leitblech des Labyrinths vom Gebläse wegweist und als eine Art Zugunterbrecher wirkt, dann wirkt das Labyrinth schon unmittelbar im Grenzbereich zum Gebläse als Zugunterbrechung.Is provided according to an embodiment that the blower facing the last baffle of the labyrinth away from the fan and acts as a kind Zugunterbrecher, then the labyrinth already acts directly in the border area to the blower as Zugunterbrechung.

Das Gebläse kann in der Abgaskammer untergebracht sein, die auch mit der Abgasführung vereinigt sein kann.The fan may be housed in the exhaust chamber, which may also be associated with the exhaust system.

Zeichnungdrawing

Die Erfindung wird anhand eines in der Zeichnung dargestellten schematischen Aufbaues eines Brenners mit Labyrinth und Gebläse näher erläutert.The invention will be explained in more detail with reference to a schematic structure of a burner with labyrinth and blower shown in the drawing.

Ausführungsbeispielembodiment

Wie der Zeichnung zu entnehmen ist, sind alle Teile des Brenners in einem Brennergehäuse untergebracht, wobei im unteren Bereich eine Armatur 11 angeordnet ist, über die Zufuhr von Luft und Gas sowie die Mischung beider Medien zum Brennstoffgemisch vorgenommen und geregelt wird. Die Ein- und Ausschaltung des Brenners kann in an sich bekannter Weise erfolgen, wobei auch die dafür notwendigen Bauteile im Gerätegehäuse 10 untergebracht sein können.As can be seen from the drawing, all parts of the burner are accommodated in a burner housing, wherein a valve 11 is arranged in the lower region, is made and regulated by the supply of air and gas and the mixture of both media to the fuel mixture. The switching on and off of the burner can be done in a conventional manner, with the necessary components in the device housing 10 may be accommodated.

Die Armatur 11 führt über die Zuleitung 12 das Brennstoffgemisch einem Brennerelement 13 zu, wo dieses verbrannt wird. Das heiße Abgas passiert einen Wärmeübertrager 14 und gibt seine Wärmeenergie an die den Wärmeübertrager 14 durchströmende Flüssigkeit ab. Dabei kann der Wärmeübertrager 14 einen oder mehrere getrennte Flüssigkeitskreise aufweisen und in unterschiedlicher Bauweise ausgeführt sein können.The fitting 11 leads via the feed line 12, the fuel mixture to a burner element 13 where it is burned. The hot exhaust gas passes through a heat exchanger 14 and releases its heat energy to the liquid flowing through the heat exchanger 14. In this case, the heat exchanger 14 may have one or more separate fluid circuits and may be designed in different construction.

Die den Wärmeübertrager 14 über die Ausgänge 16 verlassenden Abgase 15 werden von einem Agassammler 17 vollständig aufgenommen, da dessen Eingangsöffnung 18 alle Ausgänge 16 des Wärmeübertragers 14 überdeckt.The exhaust gases 15 leaving the heat exchanger 14 via the outputs 16 are completely received by an agass collector 17, since its inlet opening 18 covers all the outlets 16 of the heat exchanger 14.

Der Abgassammler 17 hat eine im Querschnitt reduzierte Austrittsöffnung 19, die gleichzeitig die Eingangsöffnung eines Labyrinths 20 bildet. Im Gehäuse des Labyrinths 20 sind abwechselnd gegeneinander gerichtete horizontale Leitbleche 21 und 22 angebracht, die die zugeleiteten Abgase aus dem Abgassammler 17 geführt an ein Gebläse 30 weiterleiten. Dabei ist darauf zu achten, dass das letzte dem Gebläse 30 zugekehrte Leitblech 22 möglichst vom Gebläse 30 wegweisend im Labyrinth 20 angeordnet ist und so nach Art einer Zugunterbrechung in Richtung zum Wärmeübertrager 14 und dem im Brennraum angeordneten Brennerelement 13 mit der daran anstehenden Flamme wirkt. Mit dem Gebläse 30 kann daher das das Labyrinth 20 verlassende Abgas sicher der Abgasführung 40 zugeführt werden, ohne die Flammenstabilität zu beeinträchtigen. Der Brenner kann daher trotz gebläsegeförderter Abführung des Abgases mit gleichmäßigem Flammbild und niedrigen Emissionswerten betrieben werden.The exhaust gas collector 17 has a reduced cross-section outlet opening 19, which also forms the entrance opening of a labyrinth 20. In the housing of the labyrinth 20 alternately directed against each other horizontal baffles 21 and 22 are mounted, which pass the supplied exhaust gases from the exhaust manifold 17 to a fan 30. It is important to ensure that the last of the fan 30 facing baffle 22 is positioned as possible by the fan 30 pioneering in the labyrinth 20 and so acts like a train interruption in the direction of the heat exchanger 14 and arranged in the combustion chamber burner element 13 with the upcoming flame. With the blower 30, therefore, the exhaust gas leaving the labyrinth 20 can be safely supplied to the exhaust duct 40 without impairing the flame stability. The burner can therefore be operated despite fan-assisted removal of the exhaust gas with a uniform flame pattern and low emission values.

Wie das Ausführungsbeispiel zeigt, ist das dem Abgassammler 17 zugekehrte erste Leitblech 21 in Gegenrichtung zum Leitblech 22 im Gehäuse des Labyrinths 20 angebracht und wird mit der Reduzierung des Querschnitts der Austrittsöffnung 19 des Abgassammlers 17 verwendet.As the embodiment shows, the first baffle 21 facing the exhaust manifold 17 is mounted in the opposite direction to the baffle 22 in the housing of the labyrinth 20 and is used with the reduction of the cross section of the outlet opening 19 of the exhaust manifold 17.

Der Ausgang 23 des Labyrinths 20 wird mit einem axialen Eingang 31 des Gebläses 30 verbunden und führt das Abgas über einen radialen Ausgang 32 direkt der vertikal weiterführenden Abgasführung 40 zu. Ein Motor 33 übernimmt den Antrieb des Gebläses 30, der über eine zugeordnete Steuerschaltung ein- und ausschaltbar und gegebenenfalls in seiner Förderleistung geregelt werden kann.The output 23 of the labyrinth 20 is connected to an axial input 31 of the blower 30 and leads the exhaust gas via a radial outlet 32 directly the vertically continuing exhaust duct 40 to. A motor 33 takes over the drive of the blower 30, which can be switched on and off via an associated control circuit and optionally regulated in its delivery rate.

Der Abgassammler 17, das Labyrinth 20 und das Gebläse 30 mit dem Motor 33 sind in einem Abschnitt 35 untergebracht, der sich im Gerätegehäuse 10 über dem Wärmeübertrager 14 anschließt. Die Abgasführung 40 steht an der Deckwand des Gerätegehäuses 10 ab und kann in bekannter Weise angeschlossen und weiter geführt werden. In diesem Gerätegehäuse 10 können Brenner 13, Brennkammer, Wärmeübertrager 14, Abgassammler 17, Gebläse 30 und Abgasanschluss enthalten und gegen die Umgebungsluft abgedichtet sein.The exhaust manifold 17, the labyrinth 20 and the fan 30 with the motor 33 are housed in a section 35 which connects in the device housing 10 via the heat exchanger 14. The exhaust gas guide 40 is on the top wall of the device housing 10 and can be connected in a known manner and continued. In this device housing 10, burner 13, combustion chamber, heat exchanger 14, exhaust manifold 17, blower 30 and exhaust connection may be included and sealed against the ambient air.

In dem schematischen Aufbau sind nur die für die Erfindung wesentlichen Teile in Einzelheiten beschrieben. Im Übrigen kann der Brenner in bekannter Weise mit Zündeinrichtung, Abgasrückführung und dergleichen versehen und betrieben werden.In the schematic structure, only the parts essential to the invention are described in detail. Incidentally, the burner can be provided and operated in a known manner with ignition device, exhaust gas recirculation and the like.
