LFG 혼합연료의 화염 안정화 특성

초록

Landfill gas has merely half heating value compared with liquified natural gas but can be greatly utilized as a commerical fuel. The authors have examined emission characteristic plenty of CO2. With the viewpoint of fuel utilization, the comparison experiments are conducted between CH4 and LFG for searching the region of flame stabilization based upon the flame blowout at maximum fuel stream velocity. As a result, it is found that stabilization region of LFG is not improved with that of CH4 in non-swirl/or weak swirl jet diffusion flame. However, it is also known that flame stability is hardly affected by inert gas in the gas in the strong swirl considering widened flame stabilization region of LFG rather than LNG.
