Abstract (en)

[origin: EP2357410A2] The method involves producing a measuring voltage (12a), which is larger than a saturation voltage for producing an ionization current (16a) at an ionization electrode (16) of the flame monitoring system in the primary operating condition of the burner (22) by a device (12) for producing the measuring voltage in a voltage range, which varies from a voltage level above the saturation voltage and a voltage level below the saturation voltage. An independent claim is also included for a device for use in a flame monitoring system for producing a measuring voltage for flame detection corresponding to ionization current measurement.
