ABSTRACT:
An apparatus for producing a stable streamer corona discharge, used for example for cleaning exhaust gases of automobiles, has a first electrode including an electrical conductor which is made of a stainless steel bar having discrete protrusions or continuously formed protrusions produced on its surface by threading, the cross section of the protrusions being triangular or trapezoidal. A second electrode includes an electrical conductor disposed opposite to the first electrode with a space therebetween, and an insulating layer formed of suitable materials having high electrical resistances such as asbestos, ceramics, organic glasses or the like covers the second electrode over at least the whole surface opposing to the first electrode. A high voltage direct current supply or a high voltage alternating supply is connected to the first electrode and the second electrode.
