Zusammenfassung: | To provide a steam turbine which can reduce a loss caused by a steam leak, can improve turbine performance, and also can shorten an installation process at a site.SOLUTION: A steam turbine comprises an outer cabin, an inner cabin accommodated in the outer cabin, a turbine rotor penetrating the inner cabin and the outer cabin, and a support beam 130 provided in the outer cabin, extending in an axial direction of the turbine rotor, and supporting the inner cabin. The steam turbine is installed on a foundation F. The outer cabin has outer cabin support parts which are arranged at both end parts of the outer cabin in the axial direction of the turbine rotor, and supported to the foundation. The support beam has beam end parts 131 which are arranged at both end parts of the turbine rotor in the axial direction. The outer cabin support parts have support faces S124 for supporting the beam end parts. Also, the outer cabin includes a height adjustment mechanism 160 which can access the beam end parts from the outside of the outer cabin.SELECTED DRAWING: Figure 4
【課題】蒸気リークによる損失を低減し、タービン性能を向上させることが可能であって、現地での据付工程を短縮可能な蒸気タービンを提供する。【解決手段】実施形態の蒸気タービンは、外部車室と、外部車室に収容された内部車室と、内部車室および外部車室を貫通するタービンロータと、外部車室内に設けられ、タービンロータの軸方向に延び、内部車室を支持する支持梁130とを備え、基礎F上に設置される。外部車室は、タービンロータの軸方向における外部車室の両端部に設けられ、前記基礎に支持される外部車室支持部を有する。支持梁は、タービンロータの軸方向における両端部に設けられた梁端部131を有する。外部車室支持部は、梁端部を支持する支持面S124を有する。更に、外部車室の外部から梁端部にアクセス可能な高さ調整機構160を外部車室が含む。【選択図】図4 |
