Abstract

The optimum knock frequency of an electrofilter installation consisting of several filters is determined. Each filter includes a microcomputer controller and a knocking device. The knock frequency is controlled by a superimposed master computer and the optimum knock frequency for a given knock frequency, varying the frequency by the master computer, again measuring the long-term average of the dust loading, and continuing to change the frequency and measure the dust loading until the dust loading value reaches a minimum.
