  1. 1
    In a method of eliminating contaminants from a gaseous emission by generation of a plasma to which the gaseous emission is exposed for promoting chemical reaction of the contaminants, the improvement residing in the steps of:conducting the gaseous emission during discharge thereof through a reactor chamber to which said plasma is confined;supplying electrical energy to the reactor chamber for establishment of an electrical field therein;and controlling said supply of the electrical energy to the reactor chamber for breakdown of the electrical field therein to effect said generation of the plasma by corona discharge within the reactor chamber.
  2. 2
    In a method of eliminating contaminants from a gaseous emission by generation of a plasma to which the gaseous emission is exposed for promoting chemical reaction of the contaminants, the improvement residing in the steps of:conducting the gaseous emission during discharge thereof through a reaction chamber under atmospheric pressure and at a temperature substantially elevated above 300° K.;supplying electrical energy to the reactor chamber for establishment of an electrical field therein;and controlling said supply of the electrical energy to the reactor chamber for breakdown of the electrical field therein to effect said generation of the plasma by Corona discharge within the reactor chamber to which the plasma is confined.
  3. 7
    Broadest claimClaim Score 82, broad(NHIP)In a method of eliminating contaminants from a gaseous emission discharged from an incinerator by generation of a plasma to which the contaminants in the emission are exposed for promoting chemical reaction thereof, the improvement residing in the steps of:conducting the gaseous emission during said discharge from the incinerator for passage through a reactor chamber to which said plasma is confined;and supplying electrical energy to the reactor chamber for effecting said generation of the plasma therein during said passage of the gaseous emission therethrough.
