摘要
本文利用本生火焰对驰放气予混火焰的稳定性进行了研究。通过实验分析,获得火孔直径为6mm的驰放气火焰的回火和脱火随一次空气系数变化的曲线,并采用Lewis和Von Elbe提出的临界边界梯度理论,整理获得火焰稳定极限曲线。
The stability of premixed flame of burning of a kind of released gas was studied with the Bunsen-type flames. The Correlation of flash-back and blow-off phenomena to the primary air coefficients in released gas burning was obtained through experiments and analysis on a burner with flame port of 6mm inner diameter. Finally, a graph illustrating the flame stability limits was plotted in accordance with the theory on critical boundary velocity gradient proposal by Lewis and Von Elbe.
