Abstract

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Regeln eines Brenners, insbesondere eines vollvormischenden Gasbrenners, bei welchem sich eine Hauptreaktionszone des zugeführten Brennstoff-Luftgemisches unter Flammenbildung stromab von Austrittsöffnungen des Gasbrenners ausbildet, mit einem oberhalb einer Brennerplatte angeordneten Sensor, der die Temperatur im Flammenbereich erfaßt und dessen Signal den Verbrennungsprozeß beeinflußt.The invention relates to a method and a Device for regulating a burner, in particular one fully premixed gas burner, in which a Main reaction zone of the fuel-air mixture supplied with flame formation downstream of the outlet openings of the Gas burner trains, with one above one Burner plate arranged sensor that the temperature in the Flame area detected and its signal the Combustion process affected.

Es wird vorgeschlagen, daß der Abstand des Sensors (18) von der Brennerplatte (10) so bemessen wird, daß die Verbrennungstemperaturen im gesamten Leistungsbereich des Brenners innerhalb eines sich in einer Flammenfußzone ausbildenden positiven Temperaturgradientenverlaufs erfaßt werden. Dadurch ist erreicht, daß alle während des Betriebes des Gasbrenners gegebenenfalls auftretenden Änderungen der Zustandsgrößen Druck, Temperatur und Feuchte des Brennstoffs und der Luft sowie Änderungen der Gasart und des Brennstoff-Luftverhältnisses sicher, schnell und auf einfache Art und Weise erfaßt werden.

Figure 00000001
It is proposed that the distance of the sensor (18) from the burner plate (10) be dimensioned such that the combustion temperatures in the entire performance range of the burner are detected within a positive temperature gradient curve which forms in a flame base zone. This ensures that all changes in the state variables pressure, temperature and humidity of the fuel and air, as well as changes in the gas type and the fuel-air ratio, which may occur during operation of the gas burner, are detected safely, quickly and in a simple manner.
