1. A method of monitoring a burner and/or a burning behavior of a burner, the method comprising:
measuring ionization signals,
wherein the measured ionization signals are used for monitoring the burner and/or the burning behavior of the burner,
wherein the ionization signals are respectively measured by the ionization electrode by using the burner surface and the heat exchanger as a common counter-electrode,
wherein for a calibration and/or for a determination of parameters used when monitoring the burner, the ionization signals are measured during a hyperstoichiometric combustion, and
that a local extremum of the ionization signals is determined during the hyperstoichiometric combustion in dependence on a lambda-value of an air-fuel mixture supplied to the burner and is used for the calibration and determination.
