Method for controlling gas burner, involves connecting exhaust gas routing in combustion chamber, where measuring sensor, particularly ionization electrode detects characteristic measuring variable

摘要

The method involves connecting an exhaust gas routing (4) in a combustion chamber (3). A measuring sensor (10), particularly an ionization electrode detects a characteristic measuring variable for the air ratio in the flame or in the exhaust gas. A control or evaluation unit (9) supplies an air ratio measuring signal. A detector (11) detects a characteristic measuring variable for a thermo acoustic oscillation. The control or evaluation unit supplies a thermo acoustic-measuring signal. The air ratio is changed depending on the thermo acoustic measuring signal.
