Influence of fuel stage under idle condition on combustion efficiency for high-temperature rise combustor

  • 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.
