摘要
基于驻涡稳定的贫油预混预蒸发(LPP)燃烧室燃烧性能开展了系统的试验研究,实验中主要针对不同进口温度、进口空气流量、进口Ma数、总余气系数α等条件下的燃烧室燃烧效率和出口温度分布等燃烧性能进行了研究。在不同的燃烧工况下,LPP驻涡燃烧室得到了比较好的燃烧性能,燃烧效率大致在0.935~0.975之间变化,OTDF的变化范围为0.35~1.4。
An experimental study based on combustion performances of Trapped-Vortex Combustor(TVC) of LPP(Lean Premixed Prevaporized) was performed,mainly aiming at different inlet temperature、 inlet airflow rate、 inlet mach number、 the total residual gas coefficient a under the condition of the combustion efficiency and outlet temperature distribution of combustion performances.The combustion performances was better at different combustion conditions.The combustion efficiency was roughly between 0.935 and 0.975.OTDF changes range was from 0.35 to 1.4.
