Abstract

Abstract: A center stage combustor using direct injection and lean partial premixed pre-evaporation (DIPME) combustion technology was put forward. The characteristics of DIPME combustor are combustion stabilization in lower condition and low NO_x emission in higher condition. The LTO cycle 4 conditions (idle，approach，climb-out and take-off) of experiment investigation were conducted on single-dome DIPME combustor. The investigation results show that combustion efficiency of idle condition is near 0.99 and in other conditions exceeds 0.995. CO，UHC and NO_x emissions in LTO cycle are lower than CAEP/6 standard，especially 60.8% NO_x emission reduction of CAEP/6 standard. The DIPME combustor is compared with rich technology combustor，there is no advantage to reducing CO and UHC emission，but reducing NO_x emission is very potential.

摘要： 提出一种采用直接喷射和部分预混预蒸发(DIPME)混合燃烧技术的中心分级燃烧室，这种DIPME燃烧室具有低工况稳定燃烧，高工况低NO_x排放的特征。对采用该燃烧技术的单头部DIPME燃烧室进行LTO循环4个工况(慢车、返场、爬升和起飞)试验研究。研究结果表明:除慢车工况的燃烧效率接近0.99外，其余工况的燃烧效率均大于0.995；在LTO循环内DIPME燃烧室的CO，UHC和NO_x排放均满足CAEP/6排放标准，其中NO_x比CAEP/6低60.8%；同采用富油燃烧技术的燃烧室相比，采用该技术的DIPME燃烧室在降低CO和UHC排放上并没有什么优势，但在降低NO_x排放上潜力巨大。
