Description

FlammenüberΛvachungseinrichtung Flame monitoring device
Die Erfindung betrifft eine Flammenüberwachungseinrichtung insbesondere für Ölbrenner gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a flame monitoring device, in particular for oil burners, according to the preamble of claim 1.
Flammenüberwachungseinrichtungen der obigen Art sind aus dem Stand der Technik hinlänglich bekannt. Derartige Flammenüberwachungseinrichtungen sind Einrichtungen, die dem Steuergerät eines Brenners das Vorhandensein einer Flamme, deren Erlöschen oder auch deren Nichtbildung melden. Sie bestehen im allgemeinen aus einem Flammenfühler, der insbesondere optisch oder akustisch die Flamme überwacht, und einer elektronischen Auswerteeinrichtung, dem sogenannten Flammenverstärker.Flame monitoring devices of the above type are well known from the prior art. Flame monitoring devices of this type are devices which report to the control unit of a burner the presence of a flame, its extinction or its non-formation. They generally consist of a flame sensor, which monitors the flame optically or acoustically, and an electronic evaluation device, the so-called flame amplifier.
Nach dem Stand der Technik wird eine Flammenüberwachungseinrichtung aus Flammenfühler und Flammenverstärker als Einheit am Brennergehäuse montiert. Dies hat den Vorteil, daß die dazugehörige Elektronik - also der Flammenverstärker - nicht hohen Temperaturen ausgesetzt ist und somit hinsichtlich der Funktionsfähigkeit nicht beeinträchtigt wird. Ein weiterer Vorteil ist die freundliche Servicegängigkeit. Ein nicht unwesentlicher Nachteil besteht jedoch in der großen Entfernung des Flammenfühlers zur Flamme. Die immer höher entwickelten Mischkopfsysteme mit ihren ausgeklügelten Luftleitsystemen zur Verbrennungsoptimierung nehmen dem Flammenfühler nämlich immer mehr die Möglichkeit, optimal und betriebssicher seinen nötigen Anteil an Flammenlicht zu detektieren. Um dennoch betriebssicher einen Flammenanteil zu detektieren, werden nach dem Stand der Technik zusätzliche Lichtlöcher in den Stauscheiben geschaffen oder es werden Sichtrohre eingebaut um damit z.B. einen bestimmten, gut sichtbaren Teilauschnitt zu detektieren. Dies verkompliziert jedoch den Aufbau und die Konstruktion der Brennersysteme.According to the prior art, a flame monitoring device comprising a flame sensor and a flame amplifier is mounted as a unit on the burner housing. This has the advantage that the associated electronics - ie the flame amplifier - are not exposed to high temperatures and are therefore not impaired in terms of their functionality. Another advantage is the friendly serviceability. A not insignificant disadvantage, however, is the large distance between the flame sensor and the flame. The increasingly sophisticated mixing head systems with their sophisticated air control systems for combustion optimization are taking away from the flame sensor more and more the possibility of optimally and reliably detecting the necessary amount of flame light. In order to reliably detect a proportion of flame, additional light holes are created in the baffle plates according to the state of the art or sight tubes are installed in order to e.g. to detect a certain, clearly visible partial section. However, this complicates the structure and construction of the burner systems.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zu Grunde, eine neuartige Flarnmenüberwachungseinrichtung zu schaffen. Dieses Problem wird durch eine Flammenüberwachungseinrichtung mit den Merkmalen des Anspruchs 1 gelöst.Proceeding from this, the present invention is based on the problem of creating a novel flame monitoring device. This problem is solved by a flame monitoring device with the features of claim 1.

Die vorliegende Erfindung betrifft das Gebiet der Brennertechnik, vorzugsweise das Gebiet der Ölbrennertechnik. Dort kommen Flammenüberwachungseinrichtungen zum Einsatz, die einem Steuergerät eines Brenners das Vorhandensein einer Flamme, das Erlöschen derselben oder auch deren Nichtbildung melden. So muß nämlich z.B. bei einem Flammenabriß das Steuergerät des Brenners ein Brennstoffventil schließen, damit nicht weiterer Brennstoff in eine Brennkammer strömt und dadurch die Funktionsfähigkeit des Brenners beeinträchtigt.The present invention relates to the field of burner technology, preferably the field of oil burner technology. Flame monitoring devices are used there, which report to a control unit of a burner the presence of a flame, the extinction of the flame or its non-formation. For example, in the event of a flame, the burner control unit should close a fuel valve so that no further fuel flows into a combustion chamber and thereby impair the functionality of the burner.
Figuren 1 bis 4 zeigen ein erstes Ausführungsbeispiel der Erfindung. So zeigt Figur 1 einen Düsenstock 10 für einen Ölbrenner mit Ölvorwärmung, der eine Eintrittsseite 11 und eine Austrittsseite 12 für den Brennstoff aufweist. Erfmdungsgemäß ist in einem Gehäuseabschnitt 13 des Düsenstocks 10, der bei einem Düsenstock mit Ölvorwärmung für die Aufnahme einer Steuerungskomponente der Ölvorwärmung vorgesehen ist, ein Flammenfühler 14 der Flammenüberwachungseinrichtung angeordnet. Demgemäß ist der Flammenfühler 14 der erfindungsgemäßen Flammenüberwachungseinrichtung in dem Düsenstock 10 integriert und im Bereich des Brenner-Mischkopfes angeordnet. Die Steuerungskomponente der Ölvorwärmung, die nach dem Stand der Technik üblicherweise in diesem Gehäuseabschnitt 13 positioniert ist, ist in der Steuerungseinrichtung des Ölbrenners integriert.Figures 1 to 4 show a first embodiment of the invention. 1 shows a nozzle assembly 10 for an oil burner with oil preheating, which has an inlet side 11 and an outlet side 12 for the fuel. According to the invention, a flame sensor 14 of the flame monitoring device is arranged in a housing section 13 of the nozzle assembly 10, which is provided in a nozzle assembly with oil preheating for receiving a control component of the oil preheating. Accordingly, the flame sensor 14 of the flame monitoring device according to the invention is integrated in the nozzle assembly 10 and arranged in the region of the burner mixing head. The control component of oil preheating that is common in the prior art is positioned in this housing section 13, is integrated in the control device of the oil burner.
Ein nicht dargestellter Flammenverstärker der Flammenübeπvachungseinrichtung, der der Auswertung des vom Flammenfühler 14 erzeugten Signals dient, ist vom Flammenfühler 14 getrennt und vom Düsenstock 10 beabstandet. Der Flammenverstärker ist nämlich zusammen mit der Steuerungskomponente der Ölvorwärmung in der Steuerungseinrichtung des Ölbrenners integriert.A flame amplifier (not shown) of the flame monitoring device, which is used to evaluate the signal generated by the flame sensor 14, is separated from the flame sensor 14 and spaced from the nozzle assembly 10. The flame amplifier is namely integrated together with the control component of the oil preheating in the control device of the oil burner.
Mit einer derartigen erfindungsgemäßen Flammenüberwachungseinrichtung ist demnach einerseits gewährleistet, daß der Flammenfühler 14 möglichst nahe an der Flamme positioniert ist und damit das Vorhandensein einer Flamme sicher detektieren kann, andererseits ist gewährleistet, daß sämtliche Elektronik möglichst weit von der Flamme entfernt ist, keiner hohen Temperatur ausgesetzt ist und damit hinsichtlich ihrer Funktionsfähigkeit nicht beeinträchtigt wird.With such a flame monitoring device according to the invention, on the one hand, it is ensured that the flame sensor 14 is positioned as close as possible to the flame and thus can reliably detect the presence of a flame, on the other hand, it is ensured that all electronics are as far away from the flame as possible and not exposed to high temperatures is and is therefore not impaired in terms of their functionality.
Figur 3 zeigt den Düsenstock 10 der Figuren 1 und 2 mit weiteren Baugruppen, wobei an der Austrittsseite 12 des Düsenstocks 10 eine Düse 15 angebracht ist. Des weiteren greift am Düsenstock 10 eine Stauscheibenhalterung 16 an, die eine Stauscheibe 17 trägt. Der Flammenfühler 14 ist demnach direkt hinter der Stauscheibe 17 und damit dem Brenner- Mischkopf montiert und verfügt somit über ideale Voraussetzungen für eine sichere Detektion der Flamme des Brenners. Figur 4 kann entnommen werden, daß bei dieser erfindungsgemäßen Lösung der Flammenfühler 14 optimal an die Position von Drallschlitzen 18 innerhalb der Stauscheibe 17 ausgerichtet werden kann, was ebenfalls für eine sichere Detektion der Flamme des Brenners von Bedeutung ist. Bei anderen Mischkopfsystemen kann selbstverständlich der Düsenstock 10 und damit der Flammenfühler 14 ebenfalls so ausgerichtet werden, daß der Flammenfühler 14 durch einen beliebigen Luftdurchlaß in einen Verbrennungsraum 19 die Flamme optimal detektieren kann.FIG. 3 shows the nozzle assembly 10 of FIGS. 1 and 2 with further assemblies, a nozzle 15 being attached to the outlet side 12 of the nozzle assembly 10. Furthermore, a baffle plate holder 16, which carries a baffle plate 17, acts on the nozzle assembly 10. The flame sensor 14 is therefore mounted directly behind the baffle plate 17 and thus the burner mixing head and thus has ideal conditions for reliable detection of the flame of the burner. FIG. 4 shows that in this solution according to the invention the flame sensor 14 can be optimally aligned with the position of swirl slots 18 within the baffle plate 17, which is also important for reliable detection of the flame of the burner. In other mixing head systems, the nozzle assembly 10 and thus the flame sensor 14 can of course also be aligned so that the flame sensor 14 can optimally detect the flame through any air passage into a combustion chamber 19.
Figuren 5 und 6 zeigen ein zweites Ausführungsbeispiel der erfindungsgemäßen Flammenüberwachungseinrichtung. Bei diesem Ausführungsbeispiel sind im Düsenstock 10 insgesamt drei Flammenfühler 14 integriert. Bei dem Düsenstock 10 kann es sich um einen Düsenstock mit oder ohne Ölvorwärmung handeln. Darüber hinaus ist auch bei dem Ausführungsbeispiel gemäß Figuren 5, 6 der oder jeder Flammenverstärker für die von den Flammenfühlern 14 erzeugten Signale in der Steuerungseinrichtung für den Ölbrenner integriert und damit vom Düsenstock 10 beabstandet. Die von den Flammenfühlern 14 ermittelten Signale können miteinander verglichen werden und bei Abweichungen voneinander kann auf ein Fehlverhalten der Verbrennung, z.B. durch einseitiges Einspritzen der Öldüse, was auf ein Aufbauen von Ruß oder auf eine verschlechterte Verbrennung hindeuten kann, geschlossen werden.FIGS. 5 and 6 show a second exemplary embodiment of the flame monitoring device according to the invention. In this embodiment, a total of three flame sensors 14 are integrated in the nozzle assembly 10. The nozzle assembly 10 can be a nozzle assembly with or without oil preheating. In addition, in the exemplary embodiment according to FIGS. 5, 6, the or each flame amplifier for the signals generated by the flame sensors 14 is integrated in the control device for the oil burner and is thus spaced apart from the nozzle assembly 10. The signals determined by the flame sensors 14 can be compared with one another and, in the event of deviations from one another, can indicate a malfunction of the combustion, for example by one-sided Injection of the oil nozzle, which may indicate the build-up of soot or deteriorated combustion, should be concluded.
Figur 7 zeigt ein weiteres Ausführungsbeispiel, wobei in den dort gezeigten Düsenstock 10 zwei Flammenfühler 14 integriert sind.FIG. 7 shows a further exemplary embodiment, two flame sensors 14 being integrated in the nozzle assembly 10 shown there.
Es liegt demnach im Sinne der Erfindung, eine Flammenüberwachungseinrichtung vorzuschlagen, deren Flammenfühler 14 im Bereich des Mischkopfes positioniert ist bzw. sind, vorzugsweise in einen Düsenstock 10 mit oder ohne Ölvorwärmung zugeordnet/integriert ist bzw. sind. Der oder jeder Flammenfühler 14 kann durch feste oder freie Positionierung am Düsenstock befestigt sein. Jegliche elektronische Komponenten, die der Auswertung der von dem oder jedem Flammenfühler 14 erfaßten Signale dienen, sind in eine Steuerungseinrichtung des Brenners integriert und vom Düsenstock 10 beabstandet. Bei einem Düsenstock mit Ölvorwärmung ist darüber hinaus auch die Steuerungskomponente der Ölvorwärmung in die Steuerungseinrichtung des Ölbrenners integriert und damit vom Düsenstock beabstandet.It is therefore within the meaning of the invention to propose a flame monitoring device, the flame sensor 14 of which is or are positioned in the region of the mixing head, is preferably assigned / integrated into a nozzle assembly 10 with or without oil preheating. The or each flame sensor 14 can be attached to the nozzle assembly by fixed or free positioning. Any electronic components that are used to evaluate the signals detected by the or each flame sensor 14 are integrated in a control device of the burner and spaced from the nozzle assembly 10. In the case of a nozzle assembly with oil preheating, the control component of the oil preheating is also integrated into the control device of the oil burner and is therefore spaced from the nozzle assembly.
Der oder jede Flammenfühler kommuniziert über entsprechende Verbindungsleitungen mit der Steuerungseinrichtung des Ölbrenners und damit mit dem Flammenverstärker. Der oder jede Flammenfühler leitet entsprechende Signale an die Steuerungseinrichtung des Ölbrenners. Der oder jede Flammenfühler kann sowohl auf einem optischen als auch akustischen Funktionsprinzip beruhen. The or each flame sensor communicates via corresponding connecting lines with the control device of the oil burner and thus with the flame amplifier. The or each flame sensor sends corresponding signals to the control device of the oil burner. The or each flame sensor can be based on an optical as well as an acoustic functional principle.
