Abstract
A method for use in an electrostatic precipitator unit, of controlling, with a view to cleaning an incoming dust-laden gas, the supply of conditioning agent to the incoming contaminated gas upstream of the precipitator unit. The precipitator unit includes discharge electrodes and collecting electrodes, between which a varying high voltage is maintained by means of a pulsating direct current supplied thereto. The frequency, the pulse charge and/or pulse length of the pulsating direct current are so varied that a plurality of frequency-charge-length combinations are obtained. For each combination, a figure of merit is measured or calculated. The figures of merit are used for establishing an optimal combination. The supply of conditioning agent is adjusted in dependence upon the pulse frequency of the established optimal combination.
