Temporal behaviors of charged particles in cylindrical corona reactors

Summary form only given, as follows. Temporal variation of electrons and ions are measured in two different pulsed corona discharge reactors, which are from the dissociation of NO/sub x/ and SO/sub x/ from the flue gases of combustion engines and power plants. Industrial scale reactor with height of 3 m and diameter of 0.5 m was made for dissociation of 500 liters of flue gas per hour. The reactor is made as a three-stage cylinder-cylinder type with a rugged inner cylindrical electrode. Another reactor is scaled by one of tenth of the industrial reactor. Electric probes have been installed in both the electrodes in order to measure the density of charged particle along with floating potential. After correcting the contribution from the displacement current, effects of system parameters on the variation of charged particles and dissociation efficiency are studied along with numerical simulation.
