Experimental Study of Secondary Streamer Energy in Pulsed Corona Discharge

Secondary streamer discharge in a wire-plate pulsed streamer corona reactor can decrease the energy utilization efficiency of DeSO2. The influences of wire-to-wire spacing, wire-to-plate spacing, pulse-forming capacitance and discharge voltage on secondary streamer energy have been studied in air at atmospheric pressure. Increasing wire-to-plate spacing and decreasing pulse-forming capacitance and discharge voltage can decrease secondary streamer energy. Under the optimal wire-to-wire spacing which is 0.8–1.2 times the wire-to-plate spacing, the secondary streamer energy decreases.
