摘要： PURPOSE:To make small the torsional vibration acting on a transition piece and reduce the wear on a side seal by increasing the number of rear side support points of the transition piece and providing the support position on both side faces of the transition piece. CONSTITUTION:On the rear side face of a transition piece 4 a base 14 of the subject device is welded. A bracket 19 for mounting a transition piece 4 to a gas turbine casing is formed in a plate form, and the base 18 and the bracket 19 are connected by a pin 20. The device is mounted at two places so that the device is symmetrical with respect to both side faces. With this arrangement torsional vibration of the transition piece 4 generated around the support device becomes small. As a result, the up-and-down vibration 16 of the transition piece 4 in the vicinity of a side seal 17 also becomes small and reduces the wear on the side seal 17. Further, air 2 of relatively low temperature from a compressor directly hits the surface of the transition piece 4 round the support base 18, where a largest stress develops and lowers the metal temperature, restraining drop in the tensile strength.

摘要： PURPOSE:To minimize frictions between each component used for a gas turbine combustor by providing separate collar members at the fixing parts of the abrasive components due to mutual contacts for exhanging these members. CONSTITUTION:A separate colloar member 23 is provided on a fixing part of a combustor II and a fire spreading tube 24. The collar member 23 gets an abrasion at this fixing part, and can be replaced at a time of maintenance check, so that even if an abrasion is found in the combustor II or the fire spreading tube 24, it is avoided to have a case to exchange the tube 24. In this way, the repair and the maintenance become simple and easy with less costs required.
摘要翻译：目的：为了减少用于燃气轮机燃烧器的每个部件之间的摩擦，通过在研磨部件的固定部分处由于相互接触而伸出这些部件而提供单独的套圈部件。构成：在燃烧器II的固定部分和消火扩散管24上设置单独的胶体部件23.轴环部件23在该固定部件处磨损，并且可以在维护检查时更换，如果在燃烧器II或消防扩散管24中发现磨损，则避免了具有更换管24的壳体。以这种方式，维修和维护变得简单和容易，并且需要更少的成本。

摘要： PURPOSE:To reduce a crack and wearing generated in a seal, by dividing the seal, provided between a transition piece and a turbine inlet nozzle of a combustor, in a peripheral direction. CONSTITUTION:A seal, provided between a transition piece 4 and a turbine inlet nozzle connected to this piece in a combustor, is divided into seals 20, 21 in a peripheral direction, and the divided parts are formed in construction overlapped with each other. In this way, the seals 20, 21 never generate strong force of contact because their length is decreased as a single seal even if the turbine inlet nozzle is elongated in a radial direction. Accordingly, a crack and wearing generated in the seals 20, 21 can be reduced.
