摘要

摘要: 针对新型驻涡燃烧室开展了燃烧性能实验研究。研究首先设计研制了驻涡燃烧室模型和实验系统,然后在此基础上开展了不同油气比、进口温度和进口流量等参数影响驻涡燃烧室燃烧性能的实验研究。结果表明燃烧室可以在不同工况下顺利点火和稳定工作,同时研究表明随着进口流量的增加（0.45⁰.7kg/s）,点火性能基本不受影响,熄火特性变差;随着进口气流温度的上升（360⁵10K）,点火和熄火性能改善,燃烧效率提高。

Abstract: Trapped Vortex Combustor(TVC) is a simple,compact and high performance gas turbine combustor.The TVC design consisted of two parts,a pilot combustor for stable combustion and a main combustor for power.The effect of a variety of parameters such as inlet temperature,airflow rate and equivalence ratio on the performance of TVC had been studied.Experimental results show:(1) the ignition of the TVC is independent of the main airflow rate in the range of 0.45～0.7 kg/s;(2) the lean blowout limit is improved with a decrease in airflow rate and with a increase of inlet flow temperature of 360～510 K;(3) combustion efficiency improves with the increase of equivalence ratio to the maximum value of 99% in the range of overall equivalence ratio between 0.34～0.4.
