Abstract:
1. Control apparatus for a burner, having at least one ionization electrode disposed in a flame region of the burner, and having an actuating element, which influences the feed quantity of fuel or air in dependence upon an actuating signal, the control apparatus at least being equipped with an ionization analyzer, which is connected downstream of the ionization electrode and generates an ionization signal, and having a controller, which generates a control value x as measure of the actuating signal, at least occasionally in dependence upon the ionization signal, the control value x being fed to a calibrating unit, wherein the calibrating unit establishes one or more times after the change in a control set value the consequential change in the control value x, and in that the calibrating unit determines, on the basis of characteristic data stored in the control apparatus, an expected value for the changed control value x, and in that the calibrating unit performs at least one comparison between the established change in the control value x and the expected value, and in that, independently from the comparison result, and the calibrating unit newly determines, using one or more differential values acquired from the comparison, the control set value stored in the control apparatus, or generates a disturbance signal.
