摘要： PURPOSE:To avoid the necessity of increasing the inner diameter of a turbine casing by a method wherein the R formed at each corner of a fitting groove for receiving a nozzle diaphragm is processed deeper from the corner by a predetermined dimension in the axial and the radial direction so that the local concentration of stress on the corner is reduced without enlarging the R. CONSTITUTION:A turbine casing is provided with the fitting groove 20 for fixing the nozzle diaphragm to an inner casing 2 and the nozzle diaphragm is held stationary in the axial direction by the engaging surface 21 of the inner casing 2. Further, in order to reduce the concentration of stress of each of the corners 22 of the fitting groove 20 due to a load applied on the engaging surface 21 of the inner casing 2, the corner 22 is subjected to a R-processing. In this case, the R- processing is applied deeper by a predetermined dimension delta beyond the corner 22 in the axial direction. Thus, by so doing, the local concentration of stress is reduced without enlarging the R so that the generation of cracks at the corner is prevented and it is not necessary to increase the inner diameter of the inner casing 2.
摘要翻译：目的：为了避免增加涡轮机壳体的内径的必要性，其中形成在用于接收喷嘴隔膜的装配槽的每个角部处的R在轴向和径向方向上从角部被加深预定的尺寸方向，使得角部上的应力的局部集中度减小而不扩大R。构成：涡轮机壳体设置有用于将喷嘴隔膜固定到内壳体2的装配槽20，并且喷嘴隔膜在轴向上保持静止方向。此外，为了减少由于施加在内壳2的接合表面21上的负载而使装配槽20的每个角部22的应力集中，角部22进行R处理。在这种情况下，R轴处理在轴向方向上比角部22更深地施加超过预定尺寸的三角形。因此，通过这样做，在不扩大R的同时减小局部应力集中，从而防止角部产生裂纹，并且不需要增大内壳2的内径。

摘要： PURPOSE:To improve the extent of efficiency in a steam turbine as well as to promote the compactification of a building by setting up a high pressure part or high, medium pressure part of the steam turbine in the first shaft and a low pressure steam turbine in the second shaft downward, respectively. CONSTITUTION:A gas turbine 1, a compressor 2, and a high, medium pressure steam turbine 3 plus a generator 5 are all connected to an A shaft through a rigid coupling. Likewise, those of gas turbine 1, compressor 2, low pressure steam turbine 4 and generator 5 are all connected to a B shaft through the rigid coupling. As for a steam cycle, exhaust steam out of the low pressure turbine 4 is condensed by a condenser 6, and subjected to heat exchanging by each exhaust heat recovery boiler 7 utilizing exhaust heat of the gas turbine 1 of each shaft, it turns to high pressure and high temperature steam. Each steam to be produced out of these two boilers 7 is converged into one and fed to the high-medium pressure turbine 3. Exhaust steam out of a medium pressure part of this high-medium pressure turbine 3 is fed into the low pressure turbine 4 by a cylinder connecting pipe 8. Thus, the extent of efficiency in the steam turbine is improvable.

摘要： PURPOSE:To adjust the diametrical clearance between a rotary part and a stationary part without any interference even during running a turbine by driving a driving device which is positioned outside an external turbine, and moving an inner casing vertically. CONSTITUTION:On both sides of the lower half case of an inner casing 2, there is protrudingly-provided a supporting arm 11 which extends in a vertical direction and penetrates an outer casing 1. By driving of a driving device 12, the vertical position of the inner casing 2 can be adjusted through the supporting arm 11. At a part where the supporting arm penetrates the outer casing 1, a steam sealing device 13 is provided to prevent the atmosphere from flowing into the outer casing. It is thus possible to adjust the diametrical clearance between the rotary part and the stationary part of a steam turbine easily and completely, and adjust it even during running the turbine without any interference.
