물添加가 豫混合火焰의 燃燒效率에 미치는 影響
The effect of water addition on combustion efficiency in premixed flame
초록
본 연구에서는 예혼합화염에 물을 촘가하였을 때의 물/연료 체적비에 따른 화 염온도, 불완전가스농도(CO, THC, H
The purpose of the present investigation is to examine the effect of water addition on combustion efficieny. In this research, fuel and additive water are injected into a burner in the form of vapors through separate needle valves, the flame temperature and concentrations of soot, CO and unburned hydrocarbons were measured in a premixed flame. The results are obtained to be: In the fuel lean region, the reduction rate of CO, soot and HC by water injection increases slightly, but there is no change in the combustion efficiency. On the other hand, in the fuel rich region, the reduction rate of CO, Soot and HC by water injection increases more than that of the fuel lean region. Accordingly, combustion efficiency increases.
