Abstract
The present invention provides a bridged stream corona generator including a first electrode comprising an electrical conductor having projections on its surface; a second electrode again comprising an electrical conductor, which is located in opposition to the first electrode; insulator means applied on at least the side of the second electrode in opposition to the first electrode; a high voltage power source connected to the first and second electrodes; and means for feeding a viscous oil onto the side of the insulator means which directs to the first electrode. With this arrangement, it is possible to smooth out irregularities caused by deposits on the side of the insulator means which faces the first electrode, thereby contributing to maintaining bridged stream corona discharge in a stable manner. The present corona generator lends itself well to purifying exhaust fumes from automobiles by corona discharge.
