燃气轮机燃烧器
摘要：
本发明涉及燃气轮机燃烧器。其中，燃气轮机(10)包括压缩机(12)和位于压缩机下游的至少一个燃烧室(14)。燃烧室包括燃烧器(24)，燃烧器具有：内罩(36)，沿燃烧器的至少一部分轴向地延伸；外罩(38)，与内罩径向地分离并沿燃烧器的至少一部分轴向地延伸；和多个定子叶片(40)，在内罩与外罩之间径向地延伸。定子叶片具有邻近内罩的内端(46)和邻近外罩的外端(48)。燃烧器还包括位于定子叶片的内端或外端中的一者处的涡梢(50)。涡梢在内端与内罩或外端与外罩之间提供间隙，且涡梢包括多个燃料端口(52)。燃气轮机还包括位于燃烧室下游的涡轮机(16)。
摘要（英）：

The present invention relates to a gas turbine burner, wherein a gas turbine includes a compressor and at least one combustor downstream from the compressor. The combustor includes a burner having an inner shroud extending axially along at least a portion of the burner, an outer shroud radially separated from the inner shroud and extending axially along at least a portion of the burner, and a plurality of stator vanes extending radially between the inner shroud and the outer shroud. The stator vanes have an inner end proximate the inner shroud and an outer end proximate the outer shroud. The burner further includes a vortex tip at one of either the inner end or the outer end of the stator vanes. The vortex tip provides a gap between the inner end and the inner shroud or the outer end and the outer shroud, and the vortex tip includes a plurality of fuel ports. The gas turbine further includes a turbine downstream from the combustor.
