Abstract

An electrostatic precipitator (ESP) intermittent energization controller is included with a CPU that adaptively controls the DC power used to energize the ESP. An opacimeter is mounted to the ESP for detecting the opacity of dust particles flowing through the same. The CPU searches through a table consisting of a predetermined number of charge-pause parameter sets until one charge-pause parameter set is found to cause the difference between the detected opacity level and the preset opacity level to be within a predetermined tolerable range.
