Abstract

In an ionizer of an exhaust gas ionization system for ionizing moisture-laden gases in a channel comprising a nozzle plate having circular nozzle openings through which the gases are conducted, a high voltage electrode support grid arranged downstream of the nozzle plate and having electrode pins extending toward the nozzle openings and carrying at their free ends star structures with a number of tips projecting radially toward the circumference of the nozzle openings and being electrically charged for ionizing the moisture laden gases flowing through the nozzle openings past the star structures, the nozzle openings are sufficiently large to cause the gas flow to be slow enough to permit water to flow down along the walls of the nozzle openings against the upward flow of the gases through the nozzle openings.
