Experimental study of energy attenuation on the discharge wire in pulse discharge reactor

Pulse energy injects into reactor to producing activated radical for the removal of SO₂ and NO_x from flue gas base on corona discharge as pulse propagate alone discharge wire. For the pulse voltage waveform distortion and pulse energy attenuation alone the discharge wire can influence the numbers of activated radical, so in this paper the characteristics of pulse voltage waveform distortion, and pulse energy attenuation alone the discharge wire have been investigated. The influences of voltage, pulse-forming capacitance, wire diameter and length on pulse energy attenuation also have been studied. The results show that the pulse voltage occurs distortion when it is transmitting. Pulse width and front rise time increase with transmission distance increase. Increasing voltage, pulse-forming capacitance and discharge wire diameter can improve the attenuation rate of pulse energy. Energy attenuation becomes quicker as discharge wire is shorter. The results concluded that discharge wire length should be chosen as shorter as possible for improving the energy efficiency of discharge wire in reactor.
