Dioxin and NO_x Control Using Pilot-Scale Pulsed Corona PlasmaTechnology

Abstract

We carried out tests on certain incinerator plant for two years from 1993 through 1994, to assure the effect of pulsed corona discharge for removal of NO_x and dioxin in flue gas in the small-scale experimental apparatus. The gas volume of the test plant is 50NM³/H.

By the experiment, high performance of dioxin removal at the gas temperature of 150°C was achieved. Regarding NO_x, the reduction efficiency of NO was about 60 percents, whereas that of NO_x including NO₂ was 30 percents at most.
