Abstract
A method is disclosed for controlling the operating parameters of an electrostatic precipitator of the type having electrodes energized by pulses superimposed upon a DC-voltage. According to the method, the pulse height (i.e., amplitude) is continuously increased at a predetermined rate and spark-overs are thereby detected as reductions in the precipitator-voltage below a selectable set value and are sorted in different types according to the time of their occurrence and duration. Thereafter, the operating parameters of the precipitator are altered in dependence upon the characteristics of the actual spark-over.
