Abstract

A method for controlling the electrode cleaning of an electrostatic precipitator unit (1, 2, 3), comprising discharge electrodes and collecting electrodes, between which a high voltage is maintained. Dust deposited on the collecting electrodes is removed by mechanical rapping of the collecting electrodes by one or more mechanical impulses being periodically supplied to the electrodes individually or in groups in a predetermined manner. All the collecting electrodes of the unit are cleaned during recurrent, relatively short, rapping periods separated by rapping intervals of considerably longer duration. The rapping period is divided into two or more rapping cycles. During each rapping cycle essentially all the collecting electrodes are supplied at least one mechanical impulse. The voltage between the electrodes of the precipitator unit or the current supplied to the electrodes of the precipitator unit is reduced step-by-step between the rapping cycles and is kept essentially constant during each individual rapping cycle.
