Abstract

Die Neuerung betrifft eine Regeleinrichtung (2), insbesondere zur Regelung der Verbrennung eines Gasbrenners (1), mit mindestens einem Sensor (3) zur Ermittlung eines Luftverhältnisses eines Verbrennungsgases, wie eine Lambda-Sonde und/oder ein O2-Sensor, wobei der Sensor (3) in einem zwischen einer Brennkammer (4) und einem Abgasauslass angeordneten, von dem Verbrennungsgas in Richtung Abgasauslass durchströmten Strömungsbereich angeordnet ist. Weiter betrifft die Neuerung einen Gasbrenner (1), insbesondere ein vollvormischender Gasbrenner, für modulierende Brennwertheizgeräte, mit einer neuerungsgemäßen Regeleinrichtung (2).The innovation relates to a control device (2), in particular for controlling the combustion of a gas burner (1), with at least one sensor (3) for determining an air ratio of a combustion gas, such as a lambda probe and / or an O 2 sensor, wherein the Sensor (3) arranged in a between a combustion chamber (4) and an exhaust gas outlet, is arranged by the combustion gas in the direction of the exhaust gas outlet flow area. Furthermore, the innovation relates to a gas burner (1), in particular a vollvormischender gas burner, for modulating condensing boilers, with a control device according to the invention (2).

Es ist Aufgabe der Neuerung, die Leistungsaufnahme zum Erwärmen von Sensoren (3) zu reduzieren.It is an object of the innovation to reduce the power consumption for heating sensors (3).

Gekennzeichnet ist die neuerungsgemäße Regeleinrichtung (2) dadurch, dass der Sensor (3) in einem Teil des Strömungsbereichs angeordnet ist, in dem das Verbrennungsgas sich in einem heißen Zustand befindet, um in wärmeübertragender Wirkverbindung mit dem heißen Verbrennungsgas zu stehen.

Figure imgaf001
The control device (2) according to the invention is characterized in that the sensor (3) is arranged in a part of the flow region in which the combustion gas is in a hot state in order to be in heat-transferring active connection with the hot combustion gas.
