ABSTRACT:
A control device for an electrostatic precipitator including a plurality of filter chambers connected in series to one another comprises a first component connected to a particle density sensor at the output of the last filter chamber for computing desired values of the particle densities at the outlets of the individual filter chambers in response to the difference between a desired particle density and a measured particle density of the outflowing gases at the output of the last filter chamber. The control device includes a second component for estimating actual values of the particle densities at the outlets of the individual filter chambers and a third component connected to the first and the second component for generating control signals in response to the deviation between the computed desired particle densities and the estimated actual particle densities, the control signals being fed to individual filter control units operatively coupled to transformer and rectifier sets associated with respective filter chambers.
