    • A gas turbine combustor improves the fuel distribution from a main fuel nozzle, suppressing fluctuations of internal pressure and elevation of inner tube metal temperature, and enhancing the combustion stability and durability of the combustor. The gas turbine combustor is a multi-nozzle type premixing combustor with a nozzle outer tube (7) for forming and injecting a premixed gas of main fuel and combustion air divided and disposed in plural sections around a cone (4) for forming a diffusion flame by reaction between pilot fuel and combustion air disposed in a center of a section of a combustor inner tube (1). Nozzle holes (5a) of a main fuel nozzle (5) are formed in three positions at equal intervals on the nozzle main body wall, and one of them is disposed at the outer periphery of the combustor inner tube (1) on a diametral line linking between the center of the combustor inner tube (1) and the center of the main fuel nozzle (5), whereby the fuel distribution to the outer periphery is decreased.
    • 燃气轮机燃烧器改善来自主燃料喷嘴的燃料分布,抑制内部压力的波动和内管金属温度升高,提高燃烧器的燃烧稳定性和耐久性。 燃气轮机燃烧器是具有喷嘴外管(7)的喷嘴外管(7)的多喷嘴型预混合燃烧器,用于形成并喷射主燃料和燃烧空气的预混合气体,燃烧空气以形成扩散火焰的锥体(4)为中心分成多个部分 通过引燃燃料与设置在燃烧器内管(1)的一部分的中心的燃烧空气之间的反应。 主燃料喷嘴(5)的喷嘴孔(5a)以等间隔在喷嘴主体壁上形成三个位置,其中一个位于燃烧器内管(1)的外径上, 在燃烧器内管(1)的中心与主燃料喷嘴(5)的中心之间连接,从而减少了向外周的燃料分配。

    • A seal ring (1) securing inner shroud members (32) of stationary blades (31) is provided with arm portions (2, 3) projecting along lower surfaces of end portions of the inner shroud members (32). Honeycomb seals (4a, 4b) are mounted on the arm portions (2, 3), respectively. The honeycomb seal (4a) is disposed opposite fins (11a) provided on a rotor arm portion (11) of a platform (22) of a moving blade (21) so that a predetermined clearance (t) can be maintained between the honeycomb seal and the fins. On the other hand, the honeycomb seal (4b) is disposed opposite fins (14b) provided on a seal portion (14a) of a sealing plate (14) of the moving blade (21) so that a predetermined clearance (t) can be maintained between the honeycomb seal and the fins. The inner shroud members (32) undergo deformation after operation of the gas turbine. However, because the honeycomb seals (4a, 4b) are mounted on the arm portions (3, 2), respectively, of the seal ring (1) disposed separately and independently from the inner shroud members (32), the honeycomb seals (4a, 4b) can remain unaffected by the deformation of the inner shroud members (32), whereby the predetermined clearances (t) can be consistently maintained.
