Abstract: PURPOSE:To provide a waste heat recovery boiler with a feed water outlet distributing pipe wherein a steam-water mixed flow generated at an economizer outlet pipe at a low load of the boiler does not cause an unstable state in the control of water level and pressure of a drum so that a stable operation can be performed. CONSTITUTION:In a waste heat recovery boiler device, flow control valves 11, 12 are provided respectively in feed water pipe lines of the outlets of economizers 7, 4 and a feed water distributing pipe 22 wherein a horizontal cyclone 23 is coupled with a distribution tray 24 is provided in each of the feed water outlets for introducing steam-water mixed fluid into each steam drum 5, 8 through the flow control valve from the economizer. Consequently, steam flows out from the left and right of the outlet of the cyclone 23 into the steam drum and water falls down to the water surface of the drum through a large number of holes 26 in the bottom of the tray 24.

Abstract: PURPOSE:To prevent a rotor from being subjected to excessive thermal stresses by raising the vapor temperatures at the outlets of the superheater and the reheater of a waste heat recovery heat exchanger at a rate lower than a value allowable to a steam turbine during the period from the start to the rated operation. CONSTITUTION:Upon the start of a complex power plant, a temperature setting device 32 works, vapor temperatures of a superheater 12 and a reheater 13 are monitored with inlet side vapor temperature detectors 27, 29, cooling water flow rate adjusting valves 25, 26 are controlled so that the outlet vapor temperatures of the superheater 12 and the reheater 13 are below set values changed according to main vapor conditions and others, and temperature reducers 21, 22 work. As a result, the temperatures, at the outlets of the superheater 12 and the reheater 13, of superheated vapor supplied to a steam turbine 4 are controlled to rise at a rate lower than the value allowed to the steam turbine 4. This prevents the steam turbine device from being subjected to excessive thermal stresses.

Abstract: PURPOSE:To prevent oxygen from enclosing in a metal coverage in a hot or cold process after a specific processing and to prevent an expansion generated in the metal membrane by filling an oxide superconductor powder in an oxygen permeable tube, applying a surface reduction process at a specific temperature, and releasing the oxygen in the crystals of the oxide superconductor, which is liable to be released, in a hot processing. CONSTITUTION:An oxide superconductor powder is filled in an oxygen permeable metal tube, a surface reduction process is applied at 750 to 900 deg.C, and the oxygen in the crystals of the oxide superconductor which is liable to be released is released. Then a wiredrawing process is carried out to a specific outer dimension, heat treatments are applied at 850 to 950 deg.C and at 400 to 600 deg.C in the oxygen ambiance, and the oxygen is led to the oxygen-short rooms in the crystals of the oxide superconductor. As the oxygen permeable metal tube, silver, gold, platinum, or an alloy of them is used. And the oxide superconductor is made of a perovskite structure oxide superconductor including Y, La, and a rare earth element. In such a way, the generation of expansion in the metal membrane owing to the heat treatments is prevented, and the generation of bores and cracks is suppressed.
