ABSTRACT:
A method is used for preconditioning flue gas to be treated in an electrostatic precipitator having a set of electrostatic elements which are intermittently energized by a power supply. The method uses a current sensor and a voltage sensor to detect the current and the voltage supplied to the electrostatic elements during an energized half-cycle of the power delivered to the electrostatic precipitator and develops an indication of the intermittent power supplied to the electrostatic elements from the current and voltage sensor measurements. The amount of a conditioning agent added to the flue gas is controlled to maintain the power indication at a substantially predetermined level.
