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 gas turbine combustor capable of reducing combustion vibration in combustion.
SOLUTION: This gas turbine combustor comprises an acoustic liner widely surrounding a combustion area of a combustion chamber regardless of presence or absence of a connection pipe and a bypass duct, to effectively reduce the combustion vibration. Further a height of an acoustic case of the acoustic liner and a size of acoustic holes formed on a wall of the combustion chamber are adjusted to have the acoustic attenuation property to a wide frequency band. The bypass duct can be installed on a part on which the acoustic line is mounted, a mixing ratio of fuel and air can be constantly kept regardless of the load of a gas turbine, NOx emission can be reduced, the air introduced into the combustion chamber is introduced through the acoustic holes uniformly formed in the circumferential direction of the combustion chamber, and a distribution of the temperature of the combustion gas blown out from the combustion changer to a downstream can be unified. A cooling passage, a cooling hole or an impingement hole may be formed on the wall of the combustion chamber and a rib when necessary, thus the gas turbine combustor of high reliability can be provided.

摘要： PROBLEM TO BE SOLVED: To provide a combustor for a gas turbine capable of uniformly conducting combustion in both of gas burning and oil burning.
SOLUTION: An inner cylinder of the combustor is formed into the trumpet shape of which a diameter is gradually increased toward a downstream side. As a low flow rate area is not formed in the trumpet shape, the accumulation of oil can be prevented. Further a film is cooled by the cooling air from a cooling hole having the shape free from a stepped part on which the oil can be attached. A spacer forming the low flow rate area causing the attachment of oil, is not mounted in the cooling hole. The oil near the cooling hole is blown off by the cooling air. In the cooling hole, a part having more heat quantity has more opening ratio. As the quantity of cooling air used in a part of low heat quantity is small, the saved air can be used in combustion.

摘要翻译：要解决的问题：提供一种能够在气体燃烧和油燃烧两者中均匀地进行燃烧的燃气轮机的燃烧器。解决方案：燃烧器的内筒形成为直径向下游侧逐渐增加的喇叭形状。由于小喇叭形状中没有形成低流量面积，所以能够防止油的积聚。此外，薄膜通过冷却空气从具有可附着油的台阶部的形状的冷却孔冷却。形成导致油附着的低流量区域的间隔件没有安装在冷却孔中。冷却孔附近的油被冷却空气吹走。在冷却孔中，具有更多热量的部分具有更大的开口率。由于在低热量部分中使用的冷却空气量小，所以可以使用节省的空气来燃烧。版权所有（C）2006，JPO＆NCIPI
