Abstract
Die Erfindung betrifft eine Anordnung zum Messen einer Ionisation in einem Verbrennungsraum (2) eines Heizgerätes (1), dem ein Brenngas-Luftgemisch zuführbar ist und in dem dieses Gemisch verbrannt werden kann, wobei außer einer Zündelektrode (13) und/oder einer Masseelektrode (14) mindestens zwei Ionisationselektroden (15, 16) zur Messung der Ionisation vorhanden sind und wobei die beiden Ionisationselektroden (15, 16) jeweils einzeln mit einer Auswerteelektronik (12) verbunden oder verbindbar sind, so dass ihre lonisationssignale getrennt ausgewertet werden können. Die Ionisationselektroden (15, 16) können gleich oder unterschiedlich sein und mit derselben oder unterschiedlichen Auswerteelektroniken (12) verbunden sein. Insbesondere können Ionisationselektroden (15, 16) aus unterschiedlichen Materialien eingesetzt werden, z.B. eine zunderbeständige und eine nicht zunderbeständige. Die Erfindung erlaubt es, einen Brenngas-Luft-Verbund bei einem Heizgerät genau elektronisch zu regeln, eine hohe Sicherheit gegen Störungen bei der Ionisationsmessung und eine lange Standzeit ohne Wartung zu erreichen, wobei selbst bei einem Ausfall einzelner Komponenten ein Weiterbetrieb des Heizgerätes (1) noch möglich ist.The invention relates to an arrangement for measuring ionization in a combustion chamber (2) of a heating device (1) to which a combustible gas/air mixture can be supplied and in which this mixture can be burned, with an ignition electrode (13) and/or a ground electrode ( 14) there are at least two ionization electrodes (15, 16) for measuring the ionization and the two ionization electrodes (15, 16) are each individually connected or can be connected to evaluation electronics (12) so that their ionization signals can be evaluated separately. The ionization electrodes (15, 16) can be the same or different and can be connected to the same or different evaluation electronics (12). In particular, ionization electrodes (15, 16) made of different materials can be used, e.g. one that is scale-resistant and one that is not scale-resistant. The invention allows a combustible gas-air compound in a heater to be precisely electronically controlled, to achieve a high level of security against faults in the ionization measurement and a long service life without maintenance, with continued operation of the heater (1) even if individual components fail. is still possible.
