Abstract (en)
[origin: EP1811230A2] The method involves detecting electrical resistance of a fuel-operated burner (12) or a measuring unit on a side of the burner surface (9) for monitoring the flame and controlling fuel air ratio of the burner. The burner or the unit is associated to a constant current source, and thermal output of the burner is determined to change a resistance reference value of the fuel-air-ratio. The ratio is decreased when the measured resistance is larger than the reference value, and is increased when the measured resistance is less than the reference value.
