| 摘 要： | 对有三旋流器的单头部燃烧室进行了燃烧性能的实验研究,进行了慢车工况的贫油熄火过程及大工况的冒烟性能的研究。研究的因素考虑了不同的头部油气比(余气系数)及喷嘴形式(单或双油路)。研究结果表明:头部余气系数小时改善了贫油熄火油气比;同时,三旋流器与双油路离心喷嘴组合方案的试验表明,这种方案基本上能满足拓宽燃烧稳定工作范围的要求,但其冒烟与要求相比,其性能已与要求值相接近,在这方面尚需进一步改善。

| Abstract: | Combustor dome design with three swirlers was experimentally investigated in order taken to widen the operation stability range.The effects of different fuel-air ratio in dome and different injectors were taken into account.Experiment results exhibited that the increasing of fuel air ratio in dome had a good effect on fuel-air ratio at lean blowout,and showed that the design was promising with low fuel air ratio at lean blowout and acceptable smoke number.But at any rate some measures would still be needed to improve the performance of smoke number of the design. |
