燃气轮机的燃烧器
摘要：
本发明提供一种燃气轮机的燃烧器。该燃气轮机的燃烧器(3)包括：生成燃烧火焰的内侧预混合气体生成部(33)以及外侧预混合气体生成部(34)，在内部具有该预混合气体生成部(33、34)的内筒(31)，连接该内筒(31)和涡轮的入口部的尾筒(32)。并且，外侧预混合气体生成部(34)被配置为包围内侧预混合气体生成部(33)的外周。并且，内侧预混合气体生成部(33)和外侧预混合气体生成部(34)被配置为隔着圆筒状涡流器环(35)。在该燃烧器3中，预混合气体生成部(33、34)的预混合气体生成部出口(333、334)的内壁面中，燃烧器(3)的径向外侧的内壁面比径向内侧的内壁面更加在燃烧火焰的轴向延长。
摘要（英）：

A combustor (3) of gas turbine comprises an inner air-fuel pre-mixture generating section (33) and an outer air-fuel pre-mixture generating section (34) for generating combustion flame, an inner tube (31) having these air-fuel pre-mixture generating sections (33, 34) internally, and a tail tube (32) for connecting the inner tube (31) with the inlet of the turbine. The outer air-fuel pre-mixture generating section (34) is arranged to surround the outer circumference of the inner air-fuel pre-mixture generating section (33). The inner air-fuel pre-mixture generating section (33) and the outer air-fuel pre-mixture generating section (34) are so arranged that a tubular swirler ring (35) is positioned therebetween. Out of the inner wall faces at the outlets (333, 334) of the air-fuel pre-mixture generating sections (33, 34) in the combustor (3), the inner wall face on the outer side in the radial direction of the combustor (3) is extending further in the axial direction of combustion flamethan the inner wall face on the inner side in the radial direction of the combustor (3).
