Abstract

Bei einem Verfahren zur Überwachung eines brenngasbetriebenen Brenners (9) mit einer Brenngasleitung (2), einer Verbrennungsluftleitung (14), einem Gebläse (7), einem Volumenstrom- oder Differenzdrucksensor (4) zwischen der Brenngasleitung (2) und der Verbrennungsluftleitung (14), sowie einem Ionisationsstromsensor (11), welcher in unmittelbarer Nähe des Brenners (9) angeordnet ist, wird das Brenngas-Luft-Verhältnis abgemagert, bis das mittels Ionisationsstromsensor (11) gemessene Signal einen vorgegebenen Grenzwert über- oder unterschreitet,
ausgehend hiervon das Brenngas-Luft-Verhältnis definiert angefettet und hierbei das Signal des Volumenstrom- oder Differenzdrucksensors (4) erfasst wird,
wobei ein mutmaßlich fetteres Brenngas-Luft-Verhältnis angefahren wird als das Soll-Brenngas-Luft-Verhältnis und / oder ein mutmaßlich magereres Brenngas-Luft-Verhältnis angefahren wird als das Soll-Brenngas-Luft-Verhältnis
und in dem Fall, in dem bei dem mutmaßlich zu fetten Brenngas-Luft-Verhältnis der Volumenstrom- oder Differenzdrucksensor (4) einen Volumenstrom in Richtung Verbrennungsluftleitung (14) erfasst beziehungsweise in dem bei dem mutmaßlich zu mageren Brenngas-Luft-Verhältnis der Volumenstrom- oder Differenzdrucksensor einen Volumenstrom in Richtung Brenngasleitung (2) erfasst auf einen ordnungsgemäßen Betriebszustand geschlussfolgert wird,
während in dem Fall, in dem bei dem mutmaßlich zu fetten Brenngas-Luft-Verhältnis der Volumenstrom- oder Differenzdrucksensor (4) einen Volumenstrom in Richtung Brenngasleitung (2) erfasst beziehungsweise in dem bei dem mutmaßlich zu mageren Brenngas-Luft-Verhältnis der Volumenstrom- oder Differenzdrucksensor (4) einen Volumenstrom in Richtung Verbrennungsluftleitung (14) erfasst auf einen Einstellungsfehler geschlussfolgert wird und ein Fehlersignal ausgegeben wird
