An Experimental Study on Flame and $NO_x$ Emission Characteristics of Front Mixing Premix Combustor

저 $NO_x$ 선단 예혼합 연소기의 화염 및 $NO_x$ 배출 특성 연구

This experimental study has been mainly motivated to obtain generally applicable design correlation for the front mixing premix combustor. The design concept of the front mixing premix combustor is to minimize thermal $NO_x$ and prompt $NO_x$ formation by maintaining low peak flame temperature, and nearly uniform flame temperature through rapid mixing process near the ignition point. The present experimental results clearly indicate that the front mixing premix combustor yields the $NO_x$ level lower than 43 ppm $NO_x$ emissions and the nearly uniform temperature distribution.
