Abstract

Die Erfindung betrifft ein Verfahren zum Betrieb einer Gastherme, die mit einem Gas-Luft-Gemisch gespeist wird, das in einem in einer Brennkammer angeordneten Brenner gezündet und verbrannt wird, der lonisationsstrom in der Flamme erfasst, das Verbrennungsgas einen Wärmetauscher passiert und als Abgas einem Abgassystem zugeführt wird. Ist nach der Erfindung vorgesehen, dass das Absinken des lonisationsstromes während des Betriebes um einen vorgegebenen Betrag, der größer als die betriebsbedingten Schwankungen des lonisationsstromes als Kennzeichen für das Einsetzen von systembedingten, selbsterregten Schwingungen (Dröhnen) gewertet wird und dass daraufhin als Gegenmaßnahme eine Veränderung der Belastung und/oder der Luftzahl vorgenommen wird, dann wird das Einsetzen von selbsterregten Schwingungen (Dröhnen) erkannt und es können geeignete Gegenmaßnahmen zur Beendigung des instabilen Betriebes getroffen werden.
