Abstract

Die Erfindung betrifft einen Flächenbrenner (1) mit einer Verteilerplatte (5) und einer Brenneroberfläche, die zumindest ein erstes Faser-Gewirk (3) aufweist, und mit einer Mischkammer, aus der ein Brennstoff-Luft-Gemisch durch die Verteilerplatte zur Brenneroberfläche geführt ist. Ferner betrifft die Erfindung ein Verfahren zur Überwachung einer definierten Flammenbildung bei einem derartigen Flächenbrenner.The invention relates to a surface burner (1) with a distributor plate (5) and a burner surface, which has at least a first fiber knitted fabric (3), and with a mixing chamber, from which a fuel-air mixture is passed through the distributor plate to the burner surface , Furthermore, the invention relates to a method for monitoring a defined flame formation in such a surface burner.

Es ist Aufgabe der Erfindung, im Überwachungsbereich eine definierte Flammenbildung zu erreichen, um eine genaue Überwachung und insbesondere Luftzahlregelung zu ermöglichen.It is an object of the invention to achieve a defined flame formation in the monitoring area, in order to allow accurate monitoring and, in particular, air-number control.

Gekennzeichnet ist der erfindungsgemäße Flächenbrenner dadurch, dass die Verteilerplatte einen Überwachungsbereich (4) und einen Hauptbereich (6) aufweist, wobei das Brennstoff-Luft-Gemisch im Hauptbereich das erste Faser-Gewirk durchströmt und im Überwachungsbereich vom ersten Faser-Gewirk unbeeinflusst ist. Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass eine Flammenbildung in einem Überwachungsbereich insbesondere mit einer Überwachungselektrode (14) überwacht wird, wobei ein Brennstoff-Luft-Gemisch im Überwachungsbereich an einem ersten Faser-Gewirk, das einen Hauptbereich überdeckt, vorbei geführt wird.

Figure imgaf001
The surface burner according to the invention is characterized in that the distributor plate has a monitoring area (4) and a main area (6), wherein the fuel-air mixture in the main area flows through the first fiber knit and is unaffected in the monitoring area of the first fiber knit. The method according to the invention is characterized in that flame formation in a monitoring area is monitored, in particular with a monitoring electrode (14), wherein a fuel-air mixture in the monitoring area is guided past a first fiber knit covering a main area.
