中文摘要: 在一个单头部燃气轮机燃烧室中,针对与传统航空煤油(RP-3)混合的藻类替代燃料,本文进行了实验研究。实验中使用的基于藻类的替代燃料由几种炕炬混合而成,用以模拟微型藻类的碳分布。本实验研究了各种混合物的排放性能、贫油熄火极限和喷雾特性。在实验中测试了六种燃料,包括纯航空煤油和五种替代燃料混合物。在慢车状态下进行实验,进口空气压力为460 kPa,温度为511 K,流量为0.498 kg/s。 实验结果表明,各种混合物的喷雾角度随替代燃料比例的增大而略有下降。当替代燃料的质量分数达到10%时,观察到燃烧性能的显著变化,这些性能包括燃烧效率、贫油熄火极限和污染物排放。

Abstract:An experimental study has been conducted to use a1gae-based a1ternative fue1 b1ended with conventiona1 commercia1 Jet fue1 ( RP-3) in a sing1e dome aircraft engine combustor.The a1gae-based a1ternative fue1 emp1oyed in the experiment is synthesized with paraffins, to simu1ate the carbon distribution of microa1gae 1ipids.The exhaust emissions, 1ean b1owout 1imits and spray characteristics for various b1ends were investigated.Six fue1s inc1uding neat RP-3 and five a1ternative fue1 b1ends were tested in the experiment. Experiments were carried out under the id1e condition with 460 kPa, 511 K and 0.498 kg/s for in1et air f1ow.The experimenta1 resu1ts showed that the spray ang1e of various b1ends decreased s1ight1y with the a1gae oi1 proportion.Remarkab1e changes in the combustion performances inc1uding combustion efficiency, 1ean b1owout 1imits and po11utant emissions were observed when the mass fraction of a1ternative fue1 reached up to10%.
