摘要：
In one embodiment, a system includes a turbine combustor having a combustor liner disposed about a combustion chamber, a head end upstream of the combustion chamber relative to a downstream direction of a flow of combustion gases through the combustion chamber, a flow sleeve disposed at an offset about the combustor liner to define a passage, and a barrier within the passage. The head end is configured to direct an oxidant flow and a first fuel flow toward the combustion chamber. The passage is configured to direct a gas flow toward the head end and to direct a portion of the oxidant flow toward a turbine end of the turbine combustor. The gas flow includes a substantially inert gas. The barrier is configured to block the portion of the oxidant flow toward the turbine end and to block the gas flow toward the head end within the passage.
摘要（中）：
在一个实施例中，一种系统包括涡轮燃烧器，该涡轮燃烧器具有布置在燃烧室周围的燃烧器衬套，相对于通过燃烧室的燃烧气体流的下游方向的燃烧室上游的头端，布置在燃烧室 在燃烧器衬套周围偏移以限定通道，以及通道内的屏障。 头端构造成将氧化剂流和第一燃料流引向燃烧室。 该通道被构造成将气流引向头端并且将一部分氧化剂流引向涡轮机燃烧器的涡轮机端。 气流包括基本上惰性的气体。 屏障被配置为阻挡氧化剂流向涡轮机端部的一部分并阻止气体流向通道内的头端。
