Abstract (en)
[origin: CA3095949A1] A method for regulating a gas burner, wherein the gas burner has a combustion air supply fan whose rotational speed can be set variably, has the following steps: operating the fan and detecting a fan rotational speed (nVBL); changing the fan rotational speed; measuring an ionization voltage (UION) which correlates with an ionization flow in a flame region of the gas burner; finding a minimum of a gradient of the measured ionization voltage at the current fan rotational speed; determining an operating point by measuring the current ionization voltage and storing as an operating point; while the burner is operating, continuously measuring the current ionization voltage; determining a deviation between the currently measured ionization voltage and the operating point; checking whether the deviation (Delta UION) is within a predefined limit (UY) and carrying out a case differentiation: + if the deviation is within the predefined limit (UY), continuing the continuous measurement of the current ionization voltage; + if the deviation is not within the predefined limit (UY), repeating the method from the above change in the fan rotational speed.
