ABSTRACT In this study, the impedance characteristics of the wire-plate pulsed
plasma reactor for deSOx and deNOx were
investigated. The experiments were carried out with a small size reactor
(15 Nm3/h) and a prototype reactor (2000 Nm3/h,
0.5 MW) using a rotary spark gap switch and magnetic pulse compression
(MPC) modulator, respectively. The impedance characteristics of the
reactor were mainly varied by varying the charge voltage, wire length
and wire-plate distance. With increasing charge voltage and wire length,
the reactor impedance was decreased. From these experiments, the best
condition for the impedance matching between the pulse generator and the
reactor was achieved. In addition, we performed an analysis of the
nonlinear reactor impedance on the basis of results of the experiment
and electromagnetic transients program (EMTP) study. From these, we
found that even though the electric equivalent circuit of the reactor
may be described by a nonlinear resistance in parallel with a varying
capacitance, the reactor impedance could be approximately analyzed using
the equivalent resistance value of the flat zone and the reactor’s
initial capacitance.

    ABSTRACT: A pulse generator of one stage MPC (magnetic pulse compression) modulator, which has average power of 7.5 kW, was developed. The modulator consists of a constant current capacitor charger (Max. 21.7 kV, 300 Hz), an initial charge capacitor (0.2 μF, 40 kV), a thyratron switch, a pulse transformer with turn ratio of 1 to 8, ceramic capacitors (2.7 nF, 160 kV) and a magnetic switch. The output voltage, current and the pulse width were obtained 85.6 kV, 1.88 kA and 200 ns (FWHM), respectively, at the initial charging voltage of 20 kV, using a dummy load of 42 Ω carbon non-inductive resistor. The energy delivery efficiency from the initial charge capacitor to the dummy load was estimated as 55 %. This modulator system can be operated at the repetition rate of maximum 300 Hz. The pulse generator is applied to a reactor of pin-to-hole type to investigate the impedance matching between the pulse generator and the reactor.

The output voltage, current and the pulsewidth of the modulator were measured to be 85.6 kV, 1.88 kA, and 200 ns (full width half maximum) respectively, with the initial charging voltage of 20 kV. This modulator system can be operated at the maximum repetition rate of 300 Hz and the energy delivery efficiency from the initial charge capacitor to the dummy load is estimated as 55%. The pulse generator is applied to a reactor of pin-to-hole type to investigate the impedance matching between the pulse generator and the reactor, and the experimental results are presented.

    ABSTRACT: 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.
