Description
Brennervorrichtung burner device
Die Erfindung bezieht sich auf eine Brennervorrichtung zur Verbrennung flüssigen Brennstoffs mit einer Zerstäuberdüse zur Vermischung des flüssigen Brennstoffs mit Verbrennungs- luft zur Bildung eines zündfähigen Gasgemischs und mit einem Flammhalter zur Stabilisierung einer das Gasgemisch verbrennenden Flamme .The invention relates to a burner device for the combustion of liquid fuel with a spray nozzle for mixing the liquid fuel with combustion air to form an ignitable gas mixture and with a flame holder for stabilizing a gas mixture burning flame.
Eine derartige Brennervorrichtung ist bekannt aus der DE 103 27 697 Al. Dieses Dokument umfasst einen so genannten Zerstäubungsbrenner, bei dem flüssiger Brennstoff und Verbrennungsluft in einer Düse beschleunigt und verwirbelt werden, so dass der flüssige Brennstoff weitestgehend verdampft; hierdurch bildet sich ein zündfähiges Brenngasgemisch aus. Das Gasgemisch wird in eine Brennkammer eingespeist, wo es gezündet und verbrannt wird. Die Qualität der Verbrennung, das heißt in erster Linie ihre Vollständigkeit und Rückstandsarmut ist stark abhängig von der Vollständigkeit der Verdampfung des flüssigen Brennstoffs und seiner guten Durchmischung mit der Verbrennungsluft. Bei dem bekannten Brenner ist stromabwärts der Zerstäubungsdüse in der eigentlichen Brennkammer ein zusätzlicher Flammhalter zur Stabilisierung der Flamme angeordnet. Der Flammhalter ist als Drahtgeflecht oder Keramik-Lochplatte oder Keramikfasermatte ausgebildet und hat die Aufgabe, den Verbrennungsort zu bestimmen und zu stabilisieren. Die Verbrennung erfolgt kontrolliert und schadstoffarm innerhalb und/oder an der Oberfläche des Flammhalters.Such a burner device is known from DE 103 27 697 Al. This document includes a so-called atomizing burner, in which liquid fuel and combustion air are accelerated and swirled in a nozzle, so that the liquid fuel vaporizes as much as possible; This forms an ignitable fuel gas mixture. The gas mixture is fed into a combustion chamber where it is ignited and burned. The quality of the incineration, that is, its completeness and depletion in the first place, is highly dependent on the completeness of the evaporation of the liquid fuel and its good mixing with the combustion air. In the known burner, an additional flame holder for stabilizing the flame is arranged downstream of the atomizing nozzle in the actual combustion chamber. The flame holder is designed as a wire mesh or ceramic perforated plate or ceramic fiber mat and has the task to determine the combustion and stabilize. The combustion takes place under controlled and low-emission conditions inside and / or on the surface of the flame holder.
Nachteilig bei der bekannten Vorrichtung ist seine Anfälligkeit für eine Verkokung der Düse. Diese entsteht durch sukzessive Ablagerung von unvollständig verbranntem Brenn- stoff an der Düsenwand. Dies behindert eine optimale Zer- stäubung und verschlechtert die Verbrennung weiter, so dass sich der Koksaufbau in der Düse beschleunigt. Eine schlechtere Zerstäubung kann zu einer Verbrennung mit hoher Rußneigung und damit einhergehender verstärkter Alterung der übrigen Komponenten des Brenners, insbesondere des Wärmetauschers bzw. der Brennkammer, und somit zu einer Minderung der Wärmeleistung bis hin zum Ausfall des Brenners führen. Weiter kann eine reduzierte Zerstäubung zu einer Qualm- und Geruchsemission, insbesondere beim Brennerstart, sowie zu Flammabrissen beim Brennerbetrieb führen.A disadvantage of the known device is its susceptibility to coking of the nozzle. This is the result of successive deposition of incompletely combusted fuel at the nozzle wall. This impedes optimal decomposition. Dusting and further deteriorates the combustion, so that the coke buildup accelerates in the nozzle. A worse atomization can lead to a combustion with a high tendency to soot and concomitant increased aging of the other components of the burner, in particular the heat exchanger or the combustion chamber, and thus to a reduction of the heat output up to the failure of the burner. Furthermore, a reduced atomization can lead to a smoke and odor emission, in particular at the burner start, as well as to flame breaks during burner operation.
Es ist die Aufgabe der vorliegenden Erfindung, eine gattungsgemäße Brennervorrichtung derart weiterzubilden, dass die Verkokung der Düse reduziert wird. Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.It is the object of the present invention to develop a generic burner device such that the coking of the nozzle is reduced. This object is solved by the features of claim 1.
Vorteilhafte Ausgestaltungen und Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.Advantageous embodiments and further developments emerge from the dependent claims.
Die erfindungsgemäße Brennervorrichtung baut auf dem gattungsgemäßen Stand der Technik dadurch auf, dass der Flammhalter im Bereich des Düsenaustritts angeordnet ist. Er wird damit gegenüber den bekannten Brennervorrichtungen stromaufwärts aus der Flammkammer in den Bereich der Düse rückverlagert. Hierdurch erfolgt die oben erläuterte Flammstabilisierung unmittelbar am Düsenaustritt. Die Lage der Flammwurzel liegt nun direkt im Bereich des Düsenaustritts anstatt entfernt von der Düse im Bereich der Brennkammer. Durch die größere Nähe der Flammwurzel zur Düse erfolgt ei- ne Steigerung der Düsentemperatur während des Brennerbetriebs. Die Temperatur der Düsenwandung wird damit über die so genannte Verkokungsgrenze hinaus erhöht, so dass sich dort niederschlagender Brennstoff nicht zu Koksbildung auf der Düsenwand führen kann. Günstigerweise ist die Düse in Form einer Venturi-Düse aufgebaut oder weist zumindest in ihrem Endbereich einen divergierenden Diffusor auf. An diesem Diffusor ist bei einer bevorzugten Ausführungsform der Erfindung der Flammhalter festgelegt. Besonders vorteilhaft ist es dabei, wenn der Flammhalter einstückig mit dem Diffusor ausgebildet ist. Andererseits ist es auch möglich, den Flammhalter als separates Teil zu fertigen und am Diffusorrand oder im Diffusor an dessen Innenwand festzulegen. Die Festlegung kann dauer- haft oder reversibel erfolgen. Letzteres ermöglicht einen einfachen Austausch des Diffusors.The burner device according to the invention builds on the generic state of the art in that the flame holder is arranged in the region of the nozzle outlet. It is thus shifted back upstream of the known burner devices from the flame chamber in the region of the nozzle. As a result, the above-explained flame stabilization takes place directly at the nozzle outlet. The position of the flame root is now located directly in the area of the nozzle exit instead of away from the nozzle in the area of the combustion chamber. Due to the greater proximity of the flame root to the nozzle, an increase in the nozzle temperature takes place during burner operation. The temperature of the nozzle wall is thus increased beyond the so-called coking limit, so that there precipitating fuel can not lead to coke formation on the nozzle wall. Conveniently, the nozzle is constructed in the form of a Venturi nozzle or has at least in its end a diverging diffuser. At this diffuser is fixed in a preferred embodiment of the invention, the flame holder. It is particularly advantageous if the flame holder is formed integrally with the diffuser. On the other hand, it is also possible to manufacture the flame holder as a separate part and set on the diffuser edge or in the diffuser on the inner wall. The definition can be permanent or reversible. The latter allows easy replacement of the diffuser.
Bevorzugt ist der Flammhalter sternförmig ausgebildet. Als besonders günstig hat sich dabei die Formgebung als dreiar- miger Stern erwiesen. Ein sternförmiger Flammhalter mit vergleichsweise großen Offenbereichen setzt dem Gasstrom keinen zu großen Widerstand entgegen, wie dies bei Verwendung einer Porenscheibe oder eines Vlieses an gleicher Stelle der Fall sein kann. Dennoch wird die Vermischung durch verbesserte Turbulenzbildung in der Düse verbessert. Gleichzeitig kommt es aber hinter dem Flammhalter zu einer Aufteilung in mehrere, vergleichmäßigte Teilströmungszonen, was unmittelbar zu einer Vergleichmäßigung und Stabilisierung der Flamme führt. Dies hat neben einer effizienteren Verbrennung auch eine Reduzierung der Verbrennungsgeräusche zur Folge .Preferably, the flame holder is formed star-shaped. The design has proven to be particularly favorable as a star with three stars. A star-shaped flame holder with comparatively large open areas does not oppose the gas flow too great a resistance, as may be the case when using a pore disk or a fleece at the same location. Nevertheless, the mixing is improved by improved turbulence formation in the nozzle. At the same time, however, behind the flame holder there is a division into a plurality of uniform partial flow zones, which leads directly to a homogenization and stabilization of the flame. This results in a more efficient combustion and a reduction of combustion noise.
Bevorzugt weist die Oberfläche des Flammhalters ein poröses Material auf . Das poröse Material des Flammhalters kann un- vollständig verdampften Brennstoff schwammartig aufsaugen und nach und nach in verdampfter Form an den Gasstrom abgeben. Auf diese Weise wird auch beim Starten des Brenners im kalten Zustand ein Eintrag von Flüssigkeitströpfchen in die Brennkammer unterbunden bzw. zumindest deutlich reduziert. Der Flammhalter kann mit einem porösen Material beschichtet sein. Es wird jedoch bevorzugt, den Flammhalter aus einem porösen Material, insbesondere einer porösen Keramik auszubilden. Prinzipiell kommen aber beispielsweise auch Metall- schäume in betracht . Weiterhin kann es vorteilhaft sein, zumindest die Innenoberfläche des Düsenaustrittsbereichs wenigstens abschnittsweise aus einem porösen Material herzustellen, beispielsweise mittels Beschichtung.Preferably, the surface of the flame holder on a porous material. The porous material of the flame holder can absorb spongy vaporized fuel and gradually release it in vaporized form to the gas stream. In this way, an entry of liquid droplets in the combustion chamber is prevented or at least significantly reduced even when starting the burner in the cold state. The flame holder can be coated with a porous material be. However, it is preferred to form the flame holder from a porous material, in particular a porous ceramic. In principle, however, metal foams are also considered, for example. Furthermore, it may be advantageous to produce at least the inner surface of the nozzle exit region at least in sections from a porous material, for example by means of coating.
Ein bevorzugtes Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen beispielhaft erläutert.A preferred embodiment of the invention will be explained by way of example with reference to the drawings.

Figur 1 zeigt eine schematische Darstellung einer erfindungsgemäßen Brennervorrichtung im Bereich der Brennkammer 10 in Querschnittsansicht. Eingangsseitig der Brennkammer 10 ist eine Venturi-Düse 12 vorgesehen, durch die flüssiger Brennstoff mit Verbrennungsluft beschleunigt und verwirbelt wird, um ein zündfähiges Gasgemisch in die Brennkammer 10 einzuspeisen.1 shows a schematic representation of a burner device according to the invention in the region of the combustion chamber 10 in a cross-sectional view. On the input side of the combustion chamber 10, a Venturi nozzle 12 is provided, is accelerated by the liquid fuel with combustion air and swirled to feed an ignitable gas mixture into the combustion chamber 10.
Der Ausgangsbereich der Venturi-Düse 12 ist als in Strömungsrichtung divergierender Diffusor 14 ausgestaltet. Im Endbereich des Diffusors 14 ist ein Flammhalter 16 angeordnet. Der Flammhalter 16 steht im Wesentlichen senkrecht zur Strömungsrichtung . Figur 2 zeigt eine Ansicht auf den Flammhalter 16 gemäß der Schnittlinie II-II in Figur 1. Bei der dargestellten Ausführungsform ist der Flammhalter als dreistrahliger Stern ausgestaltet, der einen großen Freibereich 18 in der Flamm- halterebene unverstellt lässt. Hierdurch wird der Gasstrom nur geringfügig beeinträchtigt. Am Flammhalter 16 kann sich eine Flammwurzel in unmittelbarer Nachbarschaft der Düse 12 ausbilden, so dass die Düsentemperatur über die Verkokungs- grenze angehoben wird.The exit region of the venturi nozzle 12 is configured as a diffuser 14 diverging in the flow direction. In the end region of the diffuser 14, a flame holder 16 is arranged. The flame holder 16 is substantially perpendicular to the flow direction. Figure 2 shows a view of the flame holder 16 according to the section line II-II in Figure 1. In the illustrated embodiment, the flame holder is designed as a three-bladed star, leaving a large open area 18 in the flame retainer plane unadjusted. As a result, the gas flow is only slightly affected. On the flame holder 16, a flame root can form in the immediate vicinity of the nozzle 12, so that the nozzle temperature is raised above the coking limit.
Günstigerweise ist, wie bei der dargestellten Ausführungs- form realisiert, der Flammhalter aus einem porösen Material, insbesondere einer porösen Keramik geformt. Hierdurch wird eine zusätzliche Funktion des Flammhalters als Trop- fenfänger realisiert. Diese Funktion kann weiter dadurch unterstützt werden, dass wie bei der illustrierten Ausführungsform realisiert, auch die Innenwandung des Diffusors 14 mit einem porösen Material belegt ist. Insbesondere können der Diffusor und der Flammhalter einstückig aus demsel- ben porösen Material gebildet sein.Conveniently, as realized in the illustrated embodiment, the flame retainer is formed of a porous material, in particular a porous ceramic. As a result, an additional function of the flame holder is realized as a drip catcher. This function can be further supported by the fact that, as realized in the illustrated embodiment, the inner wall of the diffuser 14 is covered with a porous material. In particular, the diffuser and the flame holder can be formed in one piece from the same porous material.
Natürlich stellt die in den Zeichnungen gezeigte und in der speziellen Beschreibung diskutierte Ausführungsform nur ein illustratives Ausführungsbeispiel der vorliegenden Erfin- düng dar. Insbesondere im Hinblick auf die Materialwahl des Flammhalters, seiner speziellen Formgebung als Stern mit drei oder mehr Strahlen sowie der Ausgestaltung weiterer, in den Figuren nicht gezeigter Elemente der Brennervorrichtung und deren Ansteuerung steht dem Fachmann ein breites Spektrum an Variationsmöglichkeiten zur Verfügung.Of course, the embodiment shown in the drawings and discussed in the specific description represents only an illustrative embodiment of the present invention.
