Corona and back discharges in flue-gas simulating mixture

摘要: Abstract Results of spectroscopic investigations and current–voltage characteristics electrical discharges between a needle plate electrodes in gas mixture simulating flue gases from coal fired power plants at atmospheric pressure are presented the paper. In these investigations, back discharge was generated electrode covered with fly ash layer order to simulate conditions similar those electrostatic precipitators. To characterize physical processes discharges, emission spectra were measured compared obtained for normal corona same configuration but removed electrode. The provide information on elemental molecular composition layer. It also shown that quite different occurring ambient air.
