    Abstract: Corona discharge induced non-thermal plasma has been used for cleaning of dust particles, VOCs, NOx, SO2, etc. in flue gas Barrier discharge with ferro-electric materials can generate strong streamer corona and often be used as such applications. In this paper, the characteristics of ferro-electric barrier discharge were experimentally investigated for wire-rod and wire-quadrupole type electrode geometries. In the present experimental apparatus, all the grounding electrodes covered by 1mm thick glass tubes and with/without 0.3mm thick barium titanate sheath on corona wires were tested. Dielectric constant of barium titanate is approximately 10,000. The results show that: 1) when corona wire is covered with barium titanate sheath, discharge current slightly decreases in each electrode configuration by compared with no ferro-electric barriers; 2) compared with wire-rod, the current pulse frequency in quadrupole become higher. The effects of dielectric barriers on the discharge current waveforms were discussed in details.
