| 摘 要： | 1引言过去的30年中,传统的旋流稳定的燃烧室的设计在不断改进,这些改进减少了污染排放并且有许多已成功用于生产之中。GE飞机发动机公司和AFRL共同开发了一项用于燃气涡轮发动机的新的燃烧技术,由于在凹腔中的火焰是通过驻涡稳定,因此这种燃烧室称为驻涡燃烧室1~3]。同时,富油

| Abstract: | This paper used an alternative combustion approach to achieve low NO_x,CO emissions.This approach combines the potential advantages of a staged rich-burn,quick-mix,lean-burn(RQL) combustor with the revolutionary Trapped Vortex Combustor(TVC) concept.A Testo360 gas analyzer was used to study both the combustor's exit temperature and NO_x,CO emissions.The experimental results conducted at different excess air ratio of rich-zone,main air flow and afterbody injection velocity.The fuel used was liquefied petroleum gas.The experimental results demonstrated that NO_x emissions for RQL trapped vortex combustor was NO_x emissions reduced by 50% when CO emissions maintain the same low level compared with conventional axially-staged RQL and perforated plates combustor. |
