Abstract
A corona discharge reactor (10) and method for chemically activating various constituents of a gas stream by use of corona discharge is provided. The corona discharge reactor (10) includes within a conduit a discharge plate (30a,b) having a plurality of through openings (33) and a plurality of projecting corona discharge electrodes (31,31',35,35'), and an electrode plate (40a,b,c) having a plurality of through openings (43) displaced from and opposing the tips (32) of the corona discharge electrodes (31,31',35,35'). A pulsed energization scheme is employed to intermittently generate a uniformly distributed corona discharge cloud (1000) between the plurality of corona discharge electrode tips (32) and the electrode plate (40a,b,c) during passage of the gas stream through the conduit. In an alternate embodiment, a back corona discharge member (60a,b,c,d) formed of a high resistance material is overlaid across that face of the electrode plate (40a,b,c) opposing the tips (32) of the corona discharge electrodes (31,31',35,35'). As corona discharge is generated from the tips (32) of the corona discharge electrodes (31,31',35,35'), the intense electric field generated in the high resistan…
