Experimental Investigation on the Stabilization Characteristics of the Excess Enthalpy Flame Highly diluted with N₂

질소로 과다 희석된 초과엔탈피 화염의 다공체 내 안정화 특성에 대한 실험적 연구

Stabilization characteristics of highly $N_2$-diluted $CH_4-O_2$ flame in an axially two-section porous inert medium were experimentally investigated for its application to the waste gas scrubber in semiconductor manufacturing processes. The flame behaviors were observed with respect to the fuel and $N_2$ flow rates and the equivalence ratios. As a result, four kinds of flame behaviors such as stable, flashback crossing the interface, blowout and sudden extinction were observed.
