Abstract:The dielectric barrier corona discharge£¨DBCD£©in a wire-cylinder configuration and the dielectric barrier discharge£¨DBD£©in a coaxial cylinder configuration are investigated,then the dissipated power and gas gap voltage are calculated by analyzing the measured Lissajous figure.The researching results demonstrate that the discharge current in DBD has higher pulse amplitude than in DBCD,and with the increasing applied voltage,the energy utilization factor for SO2 removal increases in DBCD but decreases in DBD due to the difference in their electric field distribution.The experiments of SO2 removal verify that in the absence of NH3 the energy utilization factor can reach 31 g/kWh in DBCD and 39 g/kWh in DBD£®
