Abstract
A system and method for controlling energy input to a series of electrostatic dust separator devices having a common gas inlet and a common gas outlet. A detector unit is disposed in the gas outlet to detect the dust concentration or evaluate the actual dust loss in the exhausted gas. Energy control circuitry is coupled with each separator device to control the energy input to each separator device. The control circuitry is actuated by an actuating device to first change and then restore the energy input to each of the separator devices in a selected sequence to thereby change and restore the dust concentration in the exhausted gas. Computation circuitry is coupled with the detector unit to compute the change in dust concentration resulting from a certain change in energy input to each of the separator devices in the sequence. Calculator circuitry selects the separator devices producing a desired change in the dust concentration in response to the certain change in energy input to each of the separator devices. The actuating device is coupled with the calculator circuitry and the control circuitry of each separator device to change the energy input to at least one selected separator device producing the desired change in dust concentration.
