Die Neuerung betrifft einen Gasbrenner für atmosphärischen, vormischenden Betrieb nach dem Oberbegriff des Schutzanspruches 1.The innovation concerns a gas burner for atmospheric, premixed operation according to the generic term of claim 1.
Solche Brenner sind hinreichend bekannt und werden als Flächenbrenner mit einer zusammenhängenden Brenneroberfläche ausgeführt oder bestehen aus mehreren nebeneinander angeordneten Brennstäben. Die Verbrennung wird mit einer lonisationselektrode als Meßelektrode im Flammenbereich überwacht, durch die in Abhängigkeit von der Verbrennung ein lonisationsstrom fließt. Hierdurch wird beispielsweise das Signal für das Zu- bzw. Abschalten des Zündbrenners sowie das Öffnen des Hauptgasventils gewonnen.Such burners are well known and are designed as surface burners with a continuous burner surface or consist of several fuel rods arranged next to each other. The combustion is monitored with an ionization electrode as a measuring electrode in the flame area, through which an ionization current flows depending on the combustion. This generates, for example, the signal for switching the ignition burner on or off and for opening the main gas valve.
In der DE-OS 44 33 425 ist eine Regeleinrichtung, insbesondere für Gasgebläsebrenner, enthalten, welche das Gas-Luft-Verhältnis nach einem Sollwert einstellt, der dem lonisationsstrom zugeordnet ist.DE-OS 44 33 425 contains a control device, in particular for gas-jet burners, which adjusts the gas-air ratio according to a setpoint value that is assigned to the ionization current.

Bei wechselnden Gasqualitäten oder Umgebungsbedingungen ändert sich besonders bei atmosphärischen Gasbrennern die Flammenform. So kommt es bei schwachen, niedercalorischen Gasen zum Abheben der Flamme von der Brenneroberfläche. Dies kann zum Flammenabriß und somit zur Störabschaltung führen. Dagegen erzeugen hochcalorische Gase ein Aufsitzen der Flamme auf der Brenneroberfläche, welche dabei durch die thermische Belastung zerstört werden kann.When gas qualities or ambient conditions change, the shape of the flame changes, especially in atmospheric gas burners. For example, with weak, low-calorific gases, the flame lifts off the burner surface. This can lead to the flame breaking off and thus to a shutdown. In contrast, high-calorific gases cause the flame to sit on the burner surface, which can be destroyed by the thermal stress.
Durch die Verwendung von nur einer lonisationselektrode kann die Flammenform und -position nicht genau erfaßt werden, weil die Messung auf einer Ebene über der Brenneroberfläche erfolgt, die sowohl im oberen Bereich der Flamme als auch in der Flammenwurzel liegen kann.By using only one ionization electrode, the flame shape and position cannot be determined precisely because the measurement is made at a level above the burner surface, which can be either in the upper area of the flame or in the flame root.
Der Neuerung liegt die Aufgabe zugrunde, einen Gasbrenner für atmoshärischen, vormischenden Betrieb zu schaffen, bei dem durch eine Flammendetektionseinrichtung die Verbrennung gesteuert und auf wechselnde Gasqualitäten eingestellt wird.The innovation is based on the task of creating a gas burner for atmospheric, premixed operation, in which combustion is controlled by a flame detection device and adjusted to changing gas qualities.
Die Aufgabe wurde mit den im Schutzanspruch 1 enthaltenen Merkmalen gelöst. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen. The problem was solved with the features contained in claim 1. Advantageous further developments can be found in the subclaims.
Der Gasbrenner für atmosphärischen, vormischenden Betrieb besitzt eine Flammendetektionseinrichtung an der Brenneroberfläche mit mindestens zwei Flammendetektionselementen. Diese sind in einem unterschiedlichen Abstand zur Brenneroberfläche angebracht und steuern mit ihren Signalen über einen Regler die Verbrennung. Dabei erfaßt der Regler vorzugsweise das vertikale Temperatur- und/oder lonisationsbild über der Brennerober-The gas burner for atmospheric, premixed operation has a flame detection device on the burner surface with at least two flame detection elements. These are mounted at different distances from the burner surface and use their signals to control combustion via a controller. The controller preferably records the vertical temperature and/or ionization pattern above the burner surface.

fläche und vergleicht es mit einprogrammierten Sollwerten für die optimale Flammenform und -position. Insbesondere spricht der Regler die Stellglieder Gasregelarmatur oder Verbrennungsluft- bzw. Abgasgebläse an, um das gemessene Temperatur- und/oder lonisationsbild so lange zu korrigieren, bis es den Vorgabewerten für die optimale Flammenform und -position entspricht. Der Gasbrenner stellt sich somit selbständig mit seinem Regler auf schwankende Gasqualitäten oder auch andere Einflüsse ein.surface and compares it with programmed setpoints for the optimal flame shape and position. In particular, the controller addresses the actuators gas control valve or combustion air or exhaust gas fan in order to correct the measured temperature and/or ionization pattern until it corresponds to the setpoint values for the optimal flame shape and position. The gas burner thus adjusts itself independently with its controller to fluctuating gas qualities or other influences.
Mit einer vermehrten Anzahl von Thermoelementen oder lonisationselektroden kann die Auflösung entsprechend gesteigert werden. Es erfolgt eine genaue Erfassung der Verbrennungsverhältnisse in mehreren übereinanderliegenden Ebenen. Alle Sollwerte werden vorher durch Versuche bezüglich Emissionen, Gemischbildung oder Geometrie der Brenneroberfläche festgelegt.With an increased number of thermocouples or ionization electrodes, the resolution can be increased accordingly. The combustion conditions are recorded precisely in several superimposed levels. All target values are determined in advance through tests regarding emissions, mixture formation or the geometry of the burner surface.
Die Zeichnung stellt in einer einzigen Figur ein Ausführungsbeispiel der Neuerung dar.The drawing shows an example of the innovation in a single figure.
Das Gasbrenner für atmosphärischen, vormischenden Betrieb besitzt über der Brenneroberfläche 1 eine Flammendetektionseinrichtung 2. Daran sind drei Flammendetektionselemente 3 in Form von Thermoelementen oder lonisationselektroden angebracht. Diese befinden sich in einem unterschiedlichen, gestaffelten Abstand zur Brenneroberfläche 1 und steuern mit ihren Signalen über einen Regler 4 die Verbrennung. Vorzugsweise werden als Stellglieder die Gasregelarmatur 5 und das Abgasgebläse 6 vom Regler 4 angesprochen. Das gemessene Temperatur- und/oder lonisationsbild wird den im Regler 4 eingegebenen Sollwerten für die optimale Verbrennung angeglichen. The gas burner for atmospheric, premixing operation has a flame detection device 2 above the burner surface 1. Three flame detection elements 3 in the form of thermocouples or ionization electrodes are attached to it. These are located at different, staggered distances from the burner surface 1 and control the combustion with their signals via a controller 4. Preferably, the gas control valve 5 and the exhaust fan 6 are addressed by the controller 4 as actuators. The measured temperature and/or ionization image is adjusted to the setpoints entered in the controller 4 for optimal combustion.
