要約(英語): Energy efficiency for radical production in a coaxial type corona discharge reactor driven by an inductive energy storage pulsed power generator using a semiconductor opening switch with an arrester was studied. The experiment on ozone generation and NO removal were conducted to estimate the O and N radical densities in the corona reactor, respectively. The coaxial reactor consisted of a center rod wound with a spirally-twisted tungsten wire and an outer electrode. O2 and N2/NO mixed gases were injected to the reactor for ozone generation and NO removal, respectively. The O and N radical densities in the plasma ranged from 0.2 to 1.1×1020 m-3 and 1.8 to 8.0×1018 m-3 with the arrester, respectively. The energy efficiency for O radical production with the arrester ranged from 84 to 88 g/kWh, approximately 1.6 times higher than that without the arrester. The energy efficiency for N radical production with the arrester is 33 g/kWh, approximately 9 times higher than that without the arrester.
