Abstract (en)
[origin: EP1002997A2] The method involves measuring ionisation signals in the flame region using an ionisation electrode, detecting the fan speed, deriving a signal representing the current air ratio from the current ionisation signal and comparing it with a demand value, whereby the fan speed is taken into account in deriving the first signal and selecting the demand value, and deriving a control signal for the gas regulating valve from the comparison. A signal representing the current power is detected and compared with a defined value to obtain information about the burner's operating state.
