摘要：

Experimental work was conducted to investigate the flame stability limits of H-2 + C3H8, H-2 + C2H6 and H-2 + CH4 jet flames by using a single jet diffusion burner with a nozzle diameter of 2 mm. The results of 400 experimental tests showed that the increment of hydrogen composition increases the stability limits of the hydrogen-hydrocarbon jet flames. Furthermore, the results also showed that H-2 + C3H8 jet flames could be effectively lifted or blown out at a lower jet exit velocity than H-2 + C2H6 and H-2 + CH4 jet flames at similar H-2 concentrations. In addition, it was observed that the H-2 + CH4 jet flame exhibits the highest blowout velocity. It was also found that the stability limit of hydrogen-hydrocarbon jet flames starts to increase rapidly at hydrogen volumetric composition of 90% for H-2 + C3H8, 85% for H-2 + C2H6 and 70% for H-2 + CH4.
