摘要

摘要: 在中国燃气涡轮研究院的环形燃烧室试验器的高压试验台上完成了多点喷射燃烧室出口温场试验与调试.试验结果表明:可以通过头部燃油喷射点的开关来控制多点喷射燃烧室的出口温度分布,这种控制方式对出口温度分布系数的影响增大,对径向温度分布系数的影响减小.多点喷射燃烧室效率和传统燃烧室效率相当一致,表明多点喷射燃烧室的应用是可行的.试验结果对相关燃烧室的设计具有指导和参考意义.

Abstract: The experimental study on outlet temperature field in a multipoint injection combustor-sector was finished on high-pressure test facility of annular combustor in GTE(China Gas Turbine Establishment) .Experiment results indicate that the multipoint injection combustor can control the outlet temperature filed redistribution through adjusting fuel injector switches.This control would increase the overall temperature distribution factor causing by switching and reduce radial temperature distribution factor.The combustion efficiencies of multipoint combustor and conventional combustor are fairly consistent,indicating that the multipoint injection combustor is feasible.The results have considerable significance for the designs of similar combustors.
