摘要

在双级旋流多点喷射直接混合(TAMDIM)高温升燃烧室单头部试验件上进行了燃烧效率试验

对比了两种不同主副级喉道间距尺寸下的慢车主、副分级供油方案及副油路单独供油方案的燃烧效率

分析了不同主、副级当量比(副油路供油比例分别为40%，56%，65%，100%)及喉道间距对燃烧效率的影响.试验表明：主副级采用分级供油策略时

喉道间距对燃烧效率有显著影响

喉道间距设计为19.3mm

副油路供油比例控制在40%~56%

可以获得比单独副油路供油更好的燃烧效率.在扇形试验件上进行了试验验证

进一步验证了慢车分级供油策略在TAMDIM高温升燃烧室上的可行性.

Abstract

The combustion efficiency test was done on the single dome test piece of twin annular multi-point direct injection mixing(TAMDIM) high-temperature rise combustor

the idle combustion efficiency of two stages-fueled together mode and the pilot-fueled only mode with two different throat spacing sizes were compared

and the influence of different main and pilot equivalents (the pilot fuel ratio of 40%

56%

65%

100%) and throat spacing size on the combustion efficiency were analyzed. Test results show that

the throat spacing size has a great influence on the combustion efficiency when taking the two stages-fueled together mode

compared with the pilot-fueled only mode

better combustion efficiency has been obtained when the spacing of throat is 19.3 mm and the pilot fuel ratio is within the range of 40%~56%.Validated test has been done on the sector test piece finally

ulteriorly verifying the feasibility of fuel stage under idle condition in the TAMDIM high-temperature rise combustor.
