Abstract

A method for controlling an electrostatic precipitator unit, comprising discharge electrodes and collecting electrodes, between which a high voltage is maintained by a direct current supplied to the electrodes. Dust deposited on the collecting electrodes is removed by mechanical rapping of the collecting electrodes by mechanical impulses being supplied to the electrodes individually or in groups. The collecting electrodes of the precipitator unit are cleaned during recurrent, relatively short, rapping periods separated by rapping intervals, of considerably longer duration. A strategy of controlling the electrical parameters is selected and this strategy is maintained during the optimisation. The length of the interval between the rapping periods and possibly also other rapping parameters are varied. The current and voltage during the interval between the rapping periods are measured. The average ofthe current, voltage, or a quantity derived from the currrent and/or voltage, during the interval between the rapping periods, is calculated. This calculated average is used for controlling the length of the rapping intervals and/or other rapping parameters.
