与燃气涡轮机中的下游燃料和空气喷射相关的系统和装置
摘要：
本发明提供一种与燃气涡轮机中的下游燃料和空气喷射相关的系统和装置，其包括：联接到涡轮机的燃烧器，以及下游喷射系统，所述下游喷射系统包括定位在内部流动路径内的两个喷射级，第一级和第二级，其中第一级包括在初级空气和燃料喷射系统的后面的轴向位置并且第二级包括在所述第一级的后面的轴向位置。第一级和第二级的每一个包括多个圆周间隔喷射器，每个喷射器配置成将空气和燃料喷射到通过内部流动路径的流动中。第一级和第二级具有将第二级处喷射的燃料限制到小于所述第一级处喷射的燃料的50%的配置。
摘要（英）：

A gas turbine engine that includes: a combustor coupled to a turbine and a downstream injection system that includes two injection stages, a first stage and a second stage, positioned within an interior flowpath, wherein the first stage comprises an axial position that is aft of the primary air and fuel injection system and the second stage comprising an axial position that is aft of the first stage. Each of the first stage and the second stage include a plurality of circumferentially spaced injectors, each injector of which is configured to inject air and fuel into a flow through the interior flowpath. The first stage and the second stage have a configuration that limits a fuel injected at the second stage to less than 50% of a fuel injected at the first stage.
