Abstract

A method for controlling an electrostatic precipitator unit, which comprises discharge electrodes and collecting electrodes. Between the electrodes a varying high voltage is maintained by a pulsating direct current supplied thereto. Dust deposited on the collecting electrodes is removed by mechanical rapping during recurrent, relatively short rapping periods separated by rapping intervals of essentially longer duration. During the rapping period, the voltage between the electrodes is reduced in relation to the voltage between the electrodes during the intervals between the rapping periods. The frequency, pulse charge and/or pulse duration of the pulsating direct current are varied, thereby obtaining a plurality of combinations of frequency, charge and duration. A combination of frequency, charge and duration which is optimal to the operation of the precipitator unit is determined. One or more of the parameters rapping frequency, rapping force, number of raps per rapping period, and current or voltage during the rapping period are adjusted in dependence on the pulse frequency of the established optimal combination of frequency, charge and duration.
