ABSTRACT:
A system for preconditioning flue gas to be treated in an electrostatic precipitator having a set of electrostatic elements and a power supply, which supplies an intermittent power to the electrostatic elements, includes a source of a conditioning agent, and a current sensor and a voltage sensor for detecting the half-cycle current and voltage supplied to the electrostatic elements. The system also includes a power measuring circuit, responsive to the current sensor and to the voltage sensor, which develops an indication of the power supplied to the electrostatic elements and a controller, responsive to the power indication, which controls the amount of conditioning agent added to the flue gas in order to maintain the power at a substantially predetermined level.
