Abstract

An average 30-kW MPC (magnetic pulse compression) modulator has been constructed and tested with 32 /spl Omega/ resistive dummy load. This modulator can produce high power pulses (250 MW peak@100 kV) with 200 nsec pulse rise time, 500 nsec (FWHM) pulse width, and 300 Hz repetition rate. This system is used for the production of intense streamer corona discharge in a plasma reactor for the simultaneous removal of NO/sub x/ and SO/sub x/ in the flue gases from the stack. We present the operational characteristics of the MPC modulator connected to a prototype plasma reactor for the stack gas treatment system equipped with a 0.5 MWe oil burning boiler unit.
