Abstract

This study was the effect of inserting CO tube on $NO_x$ and CO emission characteristics in a compact combustion chamber. In detail, $NO_x$ and CO emission characteristics with changing of distance due to inserting CO tube between a burner and a main heat exchanger were investigated. For this study, the commercial program, FLUENT with GRI 2.11 detail reaction mechanism, was used for the numerical study and a commercial heat exchanger was tested for the experimental study. As results, when the CO tube was inserted between a burner and a main heat exchanger, it was verified that $NO_x$ and CO emissions was decreased simultaneously as CO tube was closed to a burner and the distance between CO tube and a main heat exchanger was increased.

본 연구는 컴팩트 연소실내 CO 튜브 삽입에 따른 $NO_x$ 및 CO 배출 특성에 관한 연구로써, CO 튜브 삽입에 따른 연소기와 CO튜브 사이의 거리와, CO튜브와 주열교환기 사이의 거리에 따른 배출 특성을 검토하였다. 본 연구를 위해 상용프로그램인 Fluent와 GRI 2.11 상세 반응 기구를 이용하여 수치해석과 상용 열교환기 실험을 통해 CO튜브 삽입에 관한 CO 및 $NO_x$ 배출특성을 검토하였다. 그 결과 연소기와 주열교환기 사이에 CO 튜브를 삽입하여 CO 튜브가 연소기에 근접하고 CO 튜브와 주열교환기 사이를 넓어짐으로써 $NO_x$ 및 CO 저감에 효과가 있음을 확인할 수 있었으며, 이로 인해 CO 튜브 삽입에 따른 $NO_x$ 및 CO를 동시 저감법을 확인할 수 있었다.
