산화제 질소희석이 Syngas 가스터빈 연소기의 NOx 생성특성에 미치는 영향 해석

Abstract

The present study has numerically investigated the effects of the oxidizer-side nitrogen dilution on the precise structure and NOx formation characteristics of the turbulent syngas nonpremixed flames. Eulerian particle flamelet model was used to predicted the NOx formation characteristics in the turbulent syngas swirling nonpremixed flames. Current numerical simulation was conducted for the syngas gas turbine combustor. Numericla results indicate that oxidizer-side dilution effectively suppress the formation of NOx in the turbulent syngas swirl nonpremixed flames.
