摘要： PROBLEM TO BE SOLVED: To provide a gas turbine combustor comprising an acoustic liner capable of preventing shortening of its service life by heat stress and largely adjusting its aperture ratio.
SOLUTION: A cooling groove extending obliquely to a line of intersection of a central axis and a wall of a heat chamber, is formed inside of the wall of the heat chamber in the acoustic liner. Thus uniform cooling can be performed even when a diameter of an acoustic hole is large. Inside of the acoustic liner, a cooling fin is mounted on an outer wall of the heat chamber to improve cooling efficiency. Several kinds of materials different in coefficients of thermal expansion are used in the acoustic liner. The material of high coefficient of thermal expansion is used at a part far from the heat chamber 2 and decreased in its temperature during operation, to reduce the difference in thermal expansion with respect to a part of high temperature. A housing of the acoustic liner is mounted on the heat chamber in a state of being incorporated by a bolt or inserted by a guide. Thus the thermal expansion is further relieved by the play of a mounting part. The housing is covered by a thermal shield to prevent the release of heat, thus the temperature difference from a wall surface of the heat chamber is reduced, and heat stress can be reduced.

摘要翻译：要解决的问题：提供一种燃气轮机燃烧器，其包括能够防止由于热应力而缩短其使用寿命并大大调节其开口率的声衬。解决方案：在声学衬垫中的加热室的壁的内部形成有一个倾斜地延伸到加热室的中心轴和壁的相交线的冷却槽。因此即使在声孔的直径较大的情况下也能够进行均匀的冷却。在声学衬垫的内部，散热片安装在加热室的外壁上，以提高冷却效率。在声学衬垫中使用了几种热膨胀系数不同的材料。在远离加热室2的部分使用高热膨胀系数的材料，并且在运转时其温度降低，以减少相对于高温部分的热膨胀差。声学衬垫的壳体被安装在加热室中，处于由螺栓结合或由引导件插入的状态。因此，通过安装部件的播放进一步减轻了热膨胀。壳体被热屏蔽覆盖以防止热量的释放，因此与加热室的壁表面的温度差减小，并且可以降低热应力。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a cabin deformation preventive device for reducing a deviation between upper-lower temperatures of a cabin, and preventing deformation of the cabin without separately preparing motive power for supplying a heating medium fluid with a simple constitution.
SOLUTION: Exhaust gas from a turbine casing 1 is blown off in the atmosphere from a stack 6 via an exhaust casing 4 and an exhaust chamber 5. While, an upper heat transfer pipe 7 for flowing air being the heating medium fluid for cooling is installed in contact on an outside surface of an upper casing 1a. This upper heat transfer pipe 7 communicates with a relay pipe 8, and the rear end of the relay pipe 8 is connected to the chimney 6. At this time, since the stack 6 becomes negative pressure by a drift, the air is naturally introduced into the upper heat transfer pipe 7 from the atmosphere, and is blown off from the stack 6 via the relay pipe 8 after cooling the upper casing 1a.
