Abstract
The present disclosure relates to a method for operating a burner assembly comprising a burner (1) burning an air-fuel mixture. In a step of the method, a target value for an ionization current is specified. The burner (1) is operated in a first operating state at a first specified power level. The ionization current (9) is measured using an ionization electrode (5). The measured ionization current (9) is compared with the predefined target value and a deviation is determined. When the deviation exceeds a predefined threshold value, the burner (1) is transitioned to a second operating state at a second power level. The second power level is higher than the first power level. The second power level is determined as a function of the deviation.
