摘要： PURPOSE: To restrain vibration of a rotor, by providing such an arrangement that the gap between a packing body and the outer peripheral surface of the rotor is wider along the lower half section of the rotor than the upper half section thereof.
CONSTITUTION: A packing body 10 and a rotor are arranged such that the gap between the packing body and the outer peripheral surface of the rotor is wider along the lower half section of the rotor than along the upper half section of thereof. The length of a fin 11 projected from the inner surface of the paking body is set to be longer along the lower half section of the rotor 1 than along the upper half section of the rotor 1 so that the gap S between the rotor 1 and the fin 11 is made to be constant. The circumferential pressure distribution of steam flowing into the fin 11 is such that the pressure of steam along the upper half section of the rotor 1 is higher than that along the lower half section of the rotor 1, and therefore, the rotor 1 is always pressed down. With this arrangement, it is possible to restrain vibration of the rotor 1.

摘要翻译：目的：为了抑制转子的振动，通过提供一种包装体与转子的外周面之间的间隙比转子的上半部更沿着转子的下半部较宽的方式。构成：包装体10和转子布置成使得包装体和转子的外周面之间的间隙沿着转子的下半部分比沿其上半部分更宽。从转子1的内表面突出的翅片11的长度沿着转子1的下半部分比沿着转子1的上半部分更长，使得转子1和翅片11是恒定的。流入翅片11的蒸汽的周向压力分布使得沿着转子1的上半部分的蒸汽的压力高于转子1的下半部分的压力，因此转子1总是被按压下。由此，可以抑制转子1的振动。

摘要： PURPOSE:To improve efficiency of cleaning the interior of a medium pressure turbine rotor by providing labyrinth packing on the inner peripheral wall of a nozzle box in a steam turbine with opposed flows of high and medium pressure. CONSTITUTION:A labyrinth packing 20 is provided on the inner peripheral wall of a nozzle box 13 of a steam turbine with a high pressure turbine 1 and a medium pressure turbine 2 axially opposed to each other through a medium gland part 4 in an outer casing 3. Steam leaking from an entrance part of the high pressure first stage rotor blade 7a can be prevented, by means of said packing 20, from flowing to the medium pressure turbine 2 side as cooling steam, and the temperature of the cleaning steam can be held low enough.

摘要： PURPOSE:To keep exhaust steam rate always constant by arranging a high pressure steam regulation valve and a low pressure steam regulation valve and by making depressurized main steam flow in from the low pressure regulation valve to a 2nd stage and downstream side of a turbine only when the turbine is operated at low loads. CONSTITUTION:In a steam turbine plant utilizing its exhaust steam for a water producing plant, etc., it is so constituted that while supplying main steam to a 1st stage of the turbine 1 via a high pressure steam regulation valve 21, the main steam can also be supplied after being depressurized via a low pressure steam regulation valve 32 to and downstream side of a 2nd stage. And the main steam is made to flow only during low load operation of the turbine to and downstream side of the 2nd stage, bypassing a 1st stage, of the turbine by opening the low pressure steam regulation valve 22. With this constitution, exhaust rate of the turbine can be kept constant even if loads vary.

摘要： PURPOSE:To keep the tightening force of a clamping bolt from decreasing when flanges are warmed up by high-temperature steam, by providing a protective layer of a substance with a low thermal conductivity around the clamping bolt for the contact portions of the flanges. CONSTITUTION:High-temperature steam S in a casing 1 flows into a bolt hole 6 through a steam hole 7 but the steam does not come into contact with a clamping bolt 3 and goes around a protective cylinder 9 of low thermal conductivity as shown by arrows. The steam S is then conducted to the next bolt hole through a communication hole 8 and finally flows into the low-temperature part of the casing 1. Thick flanges 2a, 2b are warmed up in a short time by the steam S but the bolt 3 is prevented by the protective cylinder 9 from being heated. For that reason, the tightening force of the clamping bolt 3 for the contact faces of the flanges 2a, 2b is kept high.

摘要： PURPOSE:To maintain the surface of a moving blade at a humid state at all times in the stage where the steam state in the vicinity of the boundary between a dry state and a humid state is exhibited in the turbine stage group of a low pressure turbine. CONSTITUTION:The steam state inside a steam turbine is monitored at all times by a pressure/temperature measuring device 23 to judge whether the actual steam state during the turbine operation is a dry state or humid state. In the dry state, a regulating valve 26 is opened to supply spray water 27 into a nozzle diaphragm 21. The spray water 27 is jetted into a steam passage part through a slit 29 formed on a nozzle 28, and the surface of a moving blade 31 is brought into a humid state by the jetted spray water 30.

摘要： PURPOSE:To adjust the cross section of a drain discharging part so as to improve the effect of a nozzle by moving an annular body arranged on the outer circumference part of a moving blade in the longitudinal direction in response to increasing/decreasing of a load on a steam turbine, and adjusting a gap between the annular body and a nozzle outer ring. CONSTITUTION:A nozzle outer ring 4 is fixed on a nozzle fitting part 7 inside a turbine, and connected to a nozzle inner ring which is located on the outer circumference part of a main shaft by means of a plurality of stator blades 5. A plurality of moving blades 8 which are fixed on the main shaft and projected radially, are installed behind the stator blades 5. An annular body 3 surrounding the moving blades 8 is installed behind the nozzle outer ring 4. In this case, the annular body 3 is attached, movably in the longitudinal direction, to the nozzle outer ring 4 by a connecting member 2. A large pressure on a nozzle inlet side is led into a pressure chamber 11 through a pressure duct 12 as necessary. A nozzle inlet side pressure 10 is actuated on the front face of the annular body 3, and a nozzle outlet side pressure 15 is actuated on the back surface thereof so that it is thus possible to decide a gap between the annular body 3 and the nozzle outer ring 4 under a condition in which the force thereof and the force actuated to the connecting member 2 are balanced each other.

摘要： PURPOSE:To prevent a low pressure turbine and a reheater from being overheated by starting a plant with a steam turbine which is driven by starting steam fed from a steam feed device for starting. CONSTITUTION:In a plant starting process, steam is introduced from a steam feed device 44 for starting to a low temperature reheat pipe 19, and a low pressure turbine 24 is driven by the steam so as to start a gas turbine 4 thereby. Therefore, when a power train system is in rotation, steam flows always to a reheater 7 and the low pressure turbine 24 passing through the low temperature reheater pipe 19, and the heating pipe of the reheater 7 is not heated to be damaged by exhaust gas of the gas turbine 4, and the low pressure turbine 24 is not set to a high temperature by a windage loss. On the other hand, in the case that the reheater 7 is not well heated, the low pressure turbine 24 is not driven by low temperature steam since the steam is fed switchingly to the low pressure turbine 24 after being passed through a high temperature reheat pipe 20.
