Abstract

The operation of a burner plate (1), passed through by mixture outlet openings (2), of a panel-burner, in particular radiation burner, is supervised by means of at least one electrode (3) which measures the ionisation in the flame region. In order to ensure that a burner flame which is usable for ionisation measurement is available to this electrode (3), a limited region (4) of the burner plate (1) is assigned to it, in which the burner flames are dimensioned with a greater length than in the remaining region of the burner plate (1). Longer burner flames in this region (4) can be achieved by dimensioning the mixture outlet openings (5) of this region (4) smaller than the remaining mixture outlet openings (2) of the burner plate (1) or by dimensioning the air proportion of the mixture supplied to the burner plate (1) in this region (4) smaller than in the remaining region of the burner plate (1). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zur Überwachung des Betriebes der von Gemischaustrittsöffnungen durchsetzten Brenner­platte eines Flächenbrenners, insbesondere Strahlungsbrenners, mittels mindestens einer die Ionisation im Flammenbereich des Brenners messenden Elektrode.
Bei solchen Flächenbrennern wird das aus Brenngas und Verbrennungs­luft bestehende, in optimalen Anteilen vorgemischte Gemisch bereits innerhalb der aus keramischem Material, Stahlwolle od.dgl. be­stehenden Brennerplatte gezündet und verbrennt mit sehr kurzen Flammen, die eine sehr kurze Reaktionszeit aufweisen. Diese Flammen können so kurz sein, daß sie nicht selbst zu sehen sind, sondern nur ein Glühen der Brennerplatte zu beobachten ist.The invention relates to a device for monitoring the operation of the burner plate of a surface burner, in particular a radiation burner, penetrated by mixture outlet openings, by means of at least one electrode measuring ionization in the flame area of the burner.
In such surface burners, the mixture of fuel gas and combustion air, which is premixed in optimal proportions, is already within the mixture of ceramic material, steel wool or the like. existing burner plate ignited and burns with very short flames, which have a very short reaction time. These flames can be so short that they cannot be seen, but only a glow from the burner plate can be observed.

Bei der Überwachung solcher Flächenbrenner ergeben sich deshalb Probleme, weil eine Überwachung mittels die Ionisation im Flam­menbereich messender Elektroden darauf beruht, daß die Leit­fähigkeit und der Gleichrichtereffekt der Brennerflammen für die Ionisationsmessung maßgebend ist. Beispielsweise kann es bei der Einstellung einer Teillast der Brennerleistung zu Störungen kommen, weil sich an der Oberseite der Brennerplatte keine zur Überwachung benutzbare Flammen ausbilden, sondern die kurzen Brennerflammen in der Brennerplatte verschwinden und unkontrollierbar werden.Problems arise when monitoring such surface burners because monitoring by means of electrodes measuring the ionization in the flame region is based on the fact that the conductivity and the rectifying effect of the burner flames are decisive for the ionization measurement. For example, malfunctions can occur when setting a partial load of the burner output because no flames that can be used for monitoring are formed on the top of the burner plate, but the short burner flames in the burner plate disappear and become uncontrollable.

Zur Lösung dieses Problems sieht die Erfindung gemäß ihrem wesentlichsten Merkmal vor, daß der die Ionisation messenden Elektrode ein begrenzter Bereich der Brennerplatte zugeordnet ist, in dem die Brennerflammen mit einer größeren Länge als im übrigen Bereich der Brennerplatte bemesen sind.To solve this problem, the invention provides according to its most important feature that the electrode measuring the ionization is assigned a limited area of the burner plate is in which the burner flames are dimensioned with a greater length than in the remaining area of the burner plate.

Diese sinnvoll unterschiedliche Bemessung der Brennerflammen läßt sich im Rahmen der Erfindung auf verschiedenerlei Arten erfolgversprechend verwirklichen.This sensibly different dimensioning of the burner flames can be successfully achieved in various ways within the scope of the invention.

So können die Gemischaustrittsöffnungen in dem der Elektrode zugeordneten Bereich mit einem geringeren Querschnitt als die den übrigen Bereich der Brennerplatte durchsetzenden Gemischaustrittsöffnungen bemessen sein, so daß das Gemisch diese kleineren Öffnungen rascher durchströmt und längere Brennerflammen bildet.Thus, the mixture outlet openings in the area assigned to the electrode can be dimensioned with a smaller cross section than the mixture outlet openings passing through the remaining area of the burner plate, so that the mixture flows through these smaller openings more quickly and forms longer burner flames.

Man kann aber zum Zeck der Verlängerung der sich im begrenzten Bereich befindlichen Brennerflammen auch den Luftanteil des der Brennerplatte in dem der Elektrode zugeordneten Bereich zugeführten Gemisches bewußt geringer bemessen als im übrigen Bereich der Brennerplatte. Auch dadurch kann die Länge der Brennerflammen örtlich vergrößert werden.However, for the purpose of extending the burner flames located in the limited area, the proportion of air in the mixture supplied to the burner plate in the area assigned to the electrode can also be deliberately made smaller than in the remaining area of the burner plate. This also increases the length of the burner flames locally.

In diesem Fall bedarf es gesonderter, an die Unterseite der Brennerplatte ansetzender Gemischführungen, die über eine gemeinsame Verbrennungsluftführung und eine gemeinsame Brenn­stoffzufuhrleitung gespeist sein können, wobei dann von der Brennstoffzufuhrleitung eine Zweigleitung in einen den begrenz­ten Bereich der Brennerplatte speisenden Zweig der Verbrennungs­luftführung mündet, die sich in einer eigenen Gemischführung fortsetzt.In this case, separate mixture guides, which are attached to the underside of the burner plate, are required, which can be fed via a common combustion air guide and a common fuel supply line, in which case a branch line opens from the fuel supply line into a branch of the combustion air guide that feeds the limited area of the burner plate continues in its own mixture management.

Ausführungsbeispiele erfindungsgemäßer Vorrichtungen sind in den Zeichnungen veranschaulicht und nachstehend an Hand der Zeichnungsfiguren erläutert.Embodiments of devices according to the invention are illustrated in the drawings and explained below with reference to the drawing figures.

Im einzelnen zeigt

  • Fig.1 eine Brennerplatte schaubildlich und
  • Fig.2 in einem Schnitt nach II-II der Fig.1.
  • Fig.3 ist ein schematischer Vertikalschnitt durch die Gemischführung eines Gasbrenners einer anderen Ausführungsform.
In detail shows
  • Fig.1 a burner plate diagrammatically and
  • Fig.2 in a section according to II-II of Fig.1.
  • 3 is a schematic vertical section through the mixture guide of a gas burner of another embodiment.

Gemäß Fig. 1 und 2 ist eine von ihrer Unterseite her mit einem Gas-Luft-Gemisch gespeiste keramische Brennerplatte 1 von Gemischaustrittsöffnungen 2 durchsetzt und wird von zwei zusammenarbeitenden, die Ionisation im Abstandsbereich messenden Elektroden 3 überwacht, die sich oberhalb der Brennerplatte 1 über einen Flächenbereich 4 dieser Platte erstrecken, in dem die Gemischaustrittsöffnungen einen etwa um die Hälfte geringeren Durchmesser aufweisen als die Gemischaustrittsöffnungen 2 im übrigen Bereich der Brennerplatte 1. Beispielsweise kann dieser die kleineren Gemischaustrittsöffnungen 5 aufweisende Bereich 4 von einem einsetzbaren Teil 6 der Oberseite der Brennerplatte gebildet sein. Infolge der unterschiedlichen Größe der Gemischaustrittsöffnungen 2 bzw. 5 bilden sich im Bereich 4 jedenfalls so lang bemessene Brennerflammen, daß den beiden an eine Stromquelle 7 angeschlossenen Elektroden 3 eine Messung und Signalisierung der Ionisation ermöglicht wird.According to FIGS. 1 and 2, a ceramic burner plate 1 fed from its underside with a gas-air mixture is penetrated by mixture outlet openings 2 and is monitored by two cooperating electrodes 3 measuring the ionization in the distance area, which are located above the burner plate 1 via a Extend surface area 4 of this plate, in which the mixture outlet openings have an approximately half smaller diameter than the mixture outlet openings 2 in the remaining region of the burner plate 1. For example, this region 4, which has the smaller mixture outlet openings 5, can be formed by an insertable part 6 of the top of the burner plate . As a result of the different sizes of the mixture outlet openings 2 and 5, burner flames are formed in the area 4 in such a way that the two electrodes 3 connected to a current source 7 are able to measure and signal ionization.

Gemäß der Ausführungsform nach Fig.3 besteht die Brennerplatte 1 aus einem leitenden Material, z.B. Stahl, Stahlwolle od.dgl., und ist gemeinsam mit der Elektrode 3 an die Stromquelle 7 angeschlossen.According to the embodiment according to FIG. 3, the burner plate 1 consists of a conductive material, for example steel, steel wool or the like, and is connected to the current source 7 together with the electrode 3.

Die Brennerplatte 1 wird auch wieder von unten her über eine Gemischführung 8 mit einem Gas-Luft-Gemisch versorgt. Die Verbrennungsluft strömt dieser Gemischführung 8 über eine Verbrennungsluftführung 9 zu, in der sich ein mit radialen Gasdüsen 10 ausgebildeter Düsenkopf 11 befindet, der über eine Gaszufuhrleitung 12 mit Brenngas gespeist wird. Eine Zweigleitung 13 dieser Gaszufuhrleitung 12 mündet in einer separaten Gemischführung 14, die nur jenen Teilbereich 4 der Brennerplatte 1 mit Gemisch versorgt, oberhalb dessen sich die Elektrode 3 befindet. Der Luftanteil in diesem dem Teilbereich 4 zugeführten Gemisch ist durch zielführende Dimensionierung der Zweigleitung 13 und der separaten Gemischführung 14 so zu bemessen, daß er in dem der Gemischführung 8 zuströmenden Gemisch höher als in der separaten Gemischführung 14 ist. Dadurch werden die Flammen, die sich an den Gemischaustritts­öffnungen 5 bilden, zwangsläufig länger als jene, die an den Gemischaustrittsöffnungen 2 ansetzen. Die längeren Flammen befähigen die Elektrode 3 zur Messung der Ionisation und zur Anzeige des Brennerbetriebes.The burner plate 1 is again supplied with a gas-air mixture from below via a mixture guide 8. The combustion air flows to this mixture guide 8 via a combustion air guide 9, in which there is a nozzle head 11 which is formed with radial gas nozzles 10 and is fed with fuel gas via a gas supply line 12. A branch line 13 of this gas supply line 12 opens into a separate mixture guide 14, which supplies only that portion 4 of the burner plate 1 with mixture above which the electrode 3 is located. The proportion of air in this mixture supplied to sub-area 4 is to be dimensioned by dimensioning the branch line 13 and the separate mixture guide 14 in such a way that it is higher in the mixture flowing into the mixture guide 8 than in the separate mixture guide 14. As a result, the flames that form at the mixture outlet openings 5 inevitably become longer than those that start at the mixture outlet openings 2. The longer flames enable the electrode 3 to measure the ionization and to display the burner operation.
