Abstract
Certain contaminants are removed from a stream of contaminant-laden commercial and industrial exhaust gases conducted through an electrostatic precipitator by passing a reagent fluid through corona discharge active zones to activate the reagent fluid as the reagent fluid is injected into the stream such that the activated reagent fluid reacts with the contaminant to be removed. A combination discharge electrode and injector carries a plurality of electrode elements which establish the corona discharge active zones and include injector passages juxtaposed with the corona discharge active zones. The reagent fluid is injected into the stream by delivering the reagent fluid through the injector passages such that the reagent fluid passes through the corona discharge active zones and is activated as the reagent fluid is injected into the stream.
