摘要： The so-called comb-type labyrinth sealing device (S1) is disposed in a gap between a rotor blade (2), i.e. a rotating member, and a labyrinth packing (9), i.e. a stationary member. The sealing device (S1) has a plurality of sealing fins (F1, F2) arranged on the opposite sides of the gap opposite to each other. The sealing fins are axially spaced apart at unequal pitches, and hence a possibility that some of the clearances between the opposite sealing fins (F1, F2) decrease when a casing holding the labyrinth packing (9) and a rotor (1) are axially displaced relative to each other due to the difference in thermal expansion between the rotator and the casing increases.

摘要： The present invention solves problems of securing high-temperature strength at elevated temperatures and of preventing steam leakage that arise when high-pressure, high-temperature steam is used for driving a steam turbine, and problems of preventing the occurrence of rubbing due to the suppression of the excessive elongation difference and of minimizing steam leakage from shaft seals. A double-wall casing structure is arranged at an area corresponding to stages from a high-pressure first stage (7) to a predetermined high-pressure stage arranged on an upstream side of a high-pressure final stage (8); and a single-wall casing structure is arranged at an area corresponding to stages which follows said predetermined high-pressure stage.
