Removal of particulate matter from combustion gas streams

Patent ·
OSTI ID:5146798
;
This patent describes an apparatus for removing particulate matter from a combustion gas stream that is passed through an electrostatic precipitator having precipitating elements therein. It comprises: first means for selectively injecting a controllably variable amount of a conditioning agent into a combustion gas stream at a location prior to the entry of the combustion gas into an electrostatic precipitator; second means for establishing the duty cycle of the power provided to a precipitating element in the electrostatic precipitator; third means for measuring the relative particulate content of the combustion gas stream after it leaves the electrostatic precipitator; and fourth means for controlling the first means and the second means in response to the measurement derived from the third means.
