摘要
低排放燃烧室技术是支撑先进绿色航空发动机发展的关键技术之一。为了加深对低排放燃烧室技术的了解,梳理了富油-淬熄-贫燃(RQL)燃烧室、贫油部分预混预蒸发(LPP)燃烧室和贫油直接喷射(LDI)燃烧室的工作原理和研究进展,对比分析了三者的排放水平。RQL燃烧室和LPP燃烧室均已应用于民航发动机中,二者的NO_(X)排放均可达到国际民航组织航空环保委员会第8版标准(CAEP/8)规定值的94%左右。LDI燃烧室的NO_(X)排放可以达到CAEP/6规定值的12%,其在更高压比时的发展潜力较大,但是受限于复杂的燃油供给系统和极高的燃油热防护需求,目前尚未应用于发动机产品中。基于航空发动机的发展需求,展望了各类燃烧室的未来重点发展方向,为中国低排放燃烧室研究提供参考。
Low emission combustor technology is one of the key technologies supporting the development of advanced green aeroengine.To enhance the understanding of low emission combustor technology,the working principle and research status of rich-burn quick-quench lean-burn(RQL)combustor,lean partial-premixed and pre-vaporized(LPP)combustor,and lean direct injection(LDI)combustor were sorted out,and the emission levels of the three were compared and analyzed.RQL combustor and LPP combustor have been applied to civil aeroengine,and their NOX emission can reach about 94%of the CAEP/8 specified value.The NO_(X) emission of LDI combustor can reach about 12%of the CAEP/6 specified value,and it has higher development potential at higher pressure ratios.However,due to the complex fuel supply system and high fuel thermal protection requirements,LDI combustor has not been applied to aeroengine products.Based on the developmental requirements of aeroengine,this study outlines the future key development directions of various combustors,offering reference for the research on low emission combustors in China.
