Abstract

A comparative investigation of an experimental and a simulation of chemical kinetics for NOx removal from silent(dielectric-barrier) discharges is presented. Several types of dielectric-barrier discharges were implemented depending upon the configuration of electrodes. The simulation was based on an approximate mathematical model for plasma cleaning of waste gas. The influence of non-uniform distributions of species due to the production of primary active particles in the streamer channel was taken into account. A comparison of observed experimental to the calculated removal efficiency of NOx showed acceptable agreement.

무성 (유전체 장벽)방전기구의 질소산화물(NOx)제거효율에 대한 화학 반응역학의 전산모사 및 실험적 특성이 비교 조사되었다. 방전 전극구조에 따른 여러 종류의 유전체 장벽 방전기구가 구현되었으며 응용 방전환경 별 질소산화물(NOx)제거특성이 이론적, 실험적으로 고찰되었다. 전산모사 모델링은 유해 배가스에 대한 플라즈마 응용기구의 수학적 근접모델을 기초로 하였고 각 방전광(스트리머) 채널의 주 활성입자 생성에 의한 화학반응 종들의 비균일, 비평형 분포특성을 고려하였다. 모델링 전산모사로 얻어진 질소산화물(NOx) 제거효율은 관찰 실험특성과 오차 허용범위 내의 일치성을 나타내었다.
