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.The invention relates to a method for operating a gas boiler, with a Gas-air mixture is fed, which is arranged in a combustion chamber Burner is ignited and burned, the ionization current in the flame recorded, the combustion gas passes through a heat exchanger and as exhaust gas is supplied to an exhaust system. Is provided according to the invention that the drop in the ionization current during operation by a predetermined value Amount greater than the operational fluctuations in the ionization current as a symbol for the use of system-related, self-excited vibrations (booming) is evaluated and that as a result Countermeasure made a change in the load and / or the air ratio then the onset of self-excited vibrations (booming) recognized and suitable countermeasures can be taken to end the unstable Operations are taken.
