燃气轮机燃烧器
摘要：
本发明提供一种燃气轮机燃烧器，即使燃料喷嘴的周围的空间狭窄，该燃气轮机燃烧器也能够容易进行燃料喷嘴与燃料喷嘴板的接合，实现对燃料喷嘴与燃料喷嘴板进行接合的精度的提高，从而提高结构的稳定性。燃气轮机燃烧器具备喷烧器(18)，所述喷烧器包括：多个燃料喷嘴(15)，其供给燃料；燃料喷嘴板(14)，其结构性地支承所述燃料喷嘴的端部，并起到将从上游侧流入的燃料向该燃料喷嘴分配的作用；以及空气孔板(13)，其具有供给燃烧用空气的多个空气孔(21)，燃气轮机燃烧器在燃料喷嘴板(14)上形成有用于插入燃料喷嘴(15)的燃料喷嘴安装用孔(44)，从燃料喷嘴板(14)的上游侧对该燃料喷嘴板(14)与向燃料喷嘴安装用孔(44)插入的燃料喷嘴(15)进行接合。
摘要（英）：

The invention provides a gas turbine combustor which can easily perform welding of fuel nozzles and a fuel nozzle plate and realize improvement of precision of welding of the fuel nozzles and the fuel nozzle plate even if the space around the fuel nozzles is narrow, thereby improving structural stability. The gas turbine combustor comprises a burner (18) including: a plurality of fuel nozzles (15) to supply a fuel (5); a fuel nozzle plate (14) to supports end portions of the fuel nozzles structurally and being configured to distribute the fuel flowing from an upstream side to the fuel nozzles; and a swirler (13) including a plurality of air holes (21) to supply combustion air, wherein the fuel nozzle plate is provided with a fuel nozzle receiving hole to receive the fuel nozzle, and the fuel nozzle plate and the fuel nozzle inserted in the fuel nozzle receiving hole are connected to each other from an upstream side of the fuel nozzle plate by welding.
