摘要： PURPOSE:To release a difference of thermal expansion caused by a variation of temperature and to increase the life and reliability of a device by a method wherein a low temperature fluid is flowed in opposition to a high temperature fluid in a space between elements of a heat exchanger in which several elements having a high temperature flow path limited by a pair of plates and a spacer are connected. CONSTITUTION:An element 6 is formed with a high temperature flow passage 5 limited by a pair of plates 1 and spacers 2. Each of the adjoining elements 6 pushes to each other a high temperature gas in an opposite direction and by the same force against uniform hot gas by a flowing-in and a flowing-out of hot temperature gas near both vertical ends 9 and 10 so as to endure the force. Therefore, there is no problem in view of a strength against a gas pressure applied inwardly against a clearance between the elements 6 to which a low temperature gas is flowed, i.e., a central part of a low temperature flow passage even if there is no specific supporting part. Except a junction between the hot temperature gas flowing-in part 9 and the flowing-out part 10, it is possible to endure a gas pressure passing within each of the elements 6 even with a displacement stopper 11 fixed to each of the curved portions 4.

摘要： PURPOSE:To have an effective utilization of an energy of cooling water heat exchanged with a hot gas and decrease a pump driving power by a method wherein a cylinder is divided into two pressure chambers with a sliding piston, a stage in which a cooling water is supplied to one chamber to discharge cooling water in the other chamber outwardly and another stage in which the water is supplied to a water spraying nozzle are alternatively carried out. CONSTITUTION:When a cooling water tank 5A is filled with a low cooling water and a sliding partition plate 10A is located at an upper part of the tank, if a cooling water outlet valve 7A and a discharging water inlet valve 8A are opened, a pressure within the tank 5A becomes a pressure in a heat exchanger 1, a hot discharged water is flowed into the tank by a cooling water discharging pump 3 to push down the partioning plate 10A and the low cooling water in the tank is flowed into the heat exchanger 1 through the valve 7A. The partioning plate 10A reaches the lower end and the valves 7A and 8A are fully closed. Then, when a cooling water inlet valve 6A and a discharging water outlet valve 9A are opened, the low cooling water is flowed into the tank 5A by a cooling water supplying pump 2, the discharged water in the tank is pushed 8 out of the system by the valve 9A, the partioning plate 10A reaches the upper end and the valves 6A and 9A are fully closed. When both systems A and B are used, the supplying and discharging of cooling water for the heat exchanger 1 can be substantially continuously carried out.

摘要： PURPOSE:To detect leakage quickly and easily with good accuracy by a method wherein the frame body of a detecting device is formed so as to be a lattice frame surrounding the ends of respective cooling tubes respectively and halogen detecting elements are incorporated into respective compartments through supporting tubes while an electric current is generated between the halogen detecting elements and the supporting tubes. CONSTITUTION:The frame body 21a of a detecting device 21 is formed so as to be a lattice frame, in which the partitioned compartments 21b surround the ends of respective cooling tubes when the frame body is applied to the outside of a tube plate and halogen detecting elements 18 are incorporated into respective compartments 21b through supporting tubes 19 while respective compartments 21b are connected to the outside of the titled device through lead wires 22. All of water chambers and the cooling tubes are kept in vacuum simultaneously and, thereafter, a predetermined amount of halogen gas is mixed into the steam side of a condenser in atmosphere. When there is leakage in the cooling tubes, the amount of an electric current conducted between an anode (halogen detecting element 18) and a cathode (supporting tube 19), which are in the compartment 21b at a position corresponding to the position of the leakage, is increased whereby the leakage is converted into an electric signal and is read at the outside of the titled device.

摘要： PURPOSE:To reduce time and man-hours for inspection by a method wherein the titled device is equipped with a cooling water system, evacuating all of the system, a soap water injection nozzle, and a borescope or an industrial television camera for observing the foaming state of the surface of a tube plate and detecting the position of leakage. CONSTITUTION:The outlet and inlet pipe 18 of cooling water is closed by a blind plate 19 tightly and a water chamber 3 as well as a cooling pipe 4 are evacuated by a vacuum pump system 20. Soap water is injected from an injecting nozzle 22 at the tip end of an expandable tube 21 against a tube plate 7 to observe the foaming state of the surface of the tube plate 7 by a borescope 23 and inspect the leakage of the tube plate 7. The expandable tube 21 and the borescope 23 are traversable in horizontal direction. If a television is employed instead of the borescope 23, the camera 24 is attached to a pan head 25 and is used while expanding the field of the sight thereof in up-and-down direction by the expandable tube 21 and in horizontal and vertical directions by the pan head 25.

摘要： PURPOSE:To effect efficient leakage detecting work by a method wherein a hot-wire anemometer, equipped with a coil type heat sensing unit with a diameter substantially equal to the outer diameter of a cooling tube, is provided in an abutting box, abutted against the outside of a tube plate and obtain a vacuum condition in the box and the cooling tube. CONSTITUTION:An abutting box 18 is applied to the outside of a tube plate 6 to keep the inside of cooling tubes 4 and the abutting boxes at both sides of cooling tubes in a vacuum. The tip end coil type heat sensing unit 23 of a hot wire anemometer 22, sealed by a packing 21, is located in the abutting box 18 and the heat sensing unit 23 opposes to the outer diametral section 24 of the cooling tube 4 while the fluctuation in a voltage, which is generated in conjunction with the reduction of temperature due to inflow air when there is leakage, is amplified and is read at the outside of the box as the changing value of an electric current. The coil type heat sensing unit 23 is constituted so as to be capable of traversing on the tube plate 6 while sliding along the packing 21. The degree of vacuum is not constant, therefore, another sealed chamber 26 which shields the periphery thereof from leaked air and another hot-wire anemometer 22' are prepared separately to compare the measured values of these two hot wire amemometers 22, 22'.

摘要： PURPOSE:To ensure safety in case of power loss, by providing a spring reaction removing means for canceling a reactive force of a spring to a change nut provided on an output shaft of planetary gears. CONSTITUTION:A rotary motion of stepping motors 1 and 2 is transmitted through a planetary gear 51 to a screw shaft 24. The screw shaft 24 provides for a linear motion to a change nut 25 having a stopper 26 to control an output oil pressure of an electric-hydraulic converter in proportion to a compressive force of springs 43 and 44. A lever 39 is branched at a lower end portion of a hook 40, and is connected to the change nut 25 by a screw. Even when the stepping motors lose a restrictive force upon power failure, the change nut is restricted by the operation of the hook to be hindered from rising, thus maintaining a controlled oil pressure just before the power failure.
