Abstract
In a method for controlling the current pulse supply to the discharge electrodes of an electrostatic precipitator unit in order to achieve maximum separation of dust from gases conducted between the discharge electrodes and the collecting electrodes of the unit at issue, current pulses (I) with a given pulse current are supplied to the discharge electrodes. The pulse frequency is varied, and instantaneous values (U.sub.p, U(I=O), U(I=O+1.6)) corresponding to one another, for the voltage (U) between the discharge electrodes and the collecting electrodes are measured for a number of pulse frequencies. Then, the current pulse supply to the discharge electrodes is set to the pulse frequency at which the highest instantaneous value has been measured.
