Influence of fuel composition difference on lean blow out

  • 摘要: 为了推进替代燃料的多元化,扩大航空燃料的组分分布。以标准航空煤油为基准,研究了柴油和高沸点费托油对燃烧室贫油熄火边界的影响。实验采用单头部燃烧室,通过改变燃烧室进出口压力,研究其熄火边界的变化规律,并分析了其与理化性质和组成的关联关系。结果显示在220kPa的出口压力下,航空煤油的熄火性能略优于另外两种燃油,高沸点费托油相比航空煤油熄火边界窄5%,而在140kPa的低压条件下,高沸点费托油的熄火边界相比航空煤油拓宽了8%。分析得到整体上低沸点烷烃和直链烷烃的熄火性能较好。
