摘要： PROBLEM TO BE SOLVED: To provide a single-shaft combined plant provided with an emergency shut-off oil system having such a constitution that a steam turbine can be independently stopped, and even when a trip valve provided to a gas turbine emergency shut-off oil line can not be opened due to failure, a gas turbine can be surely stopped. SOLUTION: The emergency shut-off oil system is constituted such that only the steam turbine 40 is stopped when a trip solenoid valve 47 for a governing valve is opened; in an emergency shut-off oil line 42 for fuel gas control valve, an emergency shut-off oil line 43 for fuel oil control valve, and an emergency shut-off oil line 46 for governing valve a master trip solenoid valve 51 is connected, via check valves 48, 49, and 50, respectively, and when the master trip solenoid valve 51 is opened, both of the steam turbine 2 and the gas turbine 1 are stopped.

摘要： PURPOSE:To prevent the idling of a turbine rotor by preventing gland steam from flowing into a low pressure turbine during the stoppage of a steam turbine. CONSTITUTION:A bypass line 21 which branchs off from the halfway of a bleed pipe 12 extending from a middle pressure turbine 2 to a low pressure feed water heater 11 and extends to a condenser 5 is provided, and moreover provided with a cutoff valve 22. In addition, a leaking steam pipe 13 extending from the inner gland of a high pressure turbine 1 to the halfway of the bleed pipe 12 is provided with a cutoff valve 23. During the stoppage of a steam turbine, the cutoff valve 22 is opened to directly flow gland steam through the bypass line 21 to the condenser 5, and the cutoff valve 23 is closed to shut off leaking gland steam for preventing the gland steam from flowing into a low pressure turbine 3. At the same time, the vacuum adjusting valve 14 of the condenser can be opened to lower the vacuum pressure in the condenser, and a jacking oil pump can be stopped once to reduce the number of revolutions of the turbine.

摘要： PROBLEM TO BE SOLVED: To remove vibration resulting from the wind mill condition of a fan by using a system having effective and simple construction.
SOLUTION: A turbo machine comprises, at least, a first rotating assembly having a first shaft, a stator, and bearings fixed to the stator and adequate for supporting the first shaft. One of the bearings is breakable when unbalance occurs in the first rotating assembly. The turbo machine has a braking means for braking the first shaft when the unbalance occurs and a joint means to be operated for joining part of the first shaft to a peripheral portion of the turbo machine at final braking operation. The turbo machine is mainly used in aircraft applications, more specifically, for an aircraft turbo jet engine.

摘要： A method and a device for cooling a low-pressure turbine section of a steam turbine connected in a water/steam circuit, include feeding a coolant flow through parts of the low-pressure turbine section, in particular during idling operation. Condensate bled from a condenser connected downstream of the steam turbine is used as a coolant for especially effective cooling while simultaneously utilizing heat obtained in the process. The condensate emits heat absorbed during the cooling to the water/steam circuit. A coolant line which is connected to the outflow side of the condenser is connected to the low-pressure turbine section. A heat exchanger is connected to the coolant line and in the water/steam circuit.
