摘要： PURPOSE:To dissolve a problem on fatigue crack occasioned by a fluctuation in a condensate temperature at a part where a sleeve is mounted to the pipe end connection part of the outlet of a heat transfer pipe, by a method wherein, in a heat exchanger being of a system wherein heated steam is condensed in a heat transfer pipe, a sleeve is mounted to the pipe end connection part of the outlet of a heat transfer pipe. CONSTITUTION:In an outlet part 19 of a heat transfer pipe 6, a heat transfer pipe 6 is secured and supported to a tube plate 7 by welding at 20, and is mounted in a state to cover the weld part 20 with a sleeve 22. The sleeve 22 is secured to a heat transfer pipe 6 on the steam upper stream side 23 and is secured at an outlet part 24 to the tube plate 7, and a space 25 is formed between the weld part 20 at a pipe end and the sleeve 22. Therefore, overcooled condensate 15 flows over the sleeve 22, and the temperature change of condensate 15 is hardly propagated to the weld part 20 due to the effect of the space 25. This constitution prevents production of a repeat thermal stress, by which the occurrence of crack is caused, at the weld port 20, and enables provision of a heater having high reliability.

摘要： PROBLEM TO BE SOLVED: To realize simple automatic control for controlling the opening of main/sub flow regulating valves, for heated steam flow of a steam turbine, without involving manual operation.
SOLUTION: In the heated steam system of a moisture separating heater that drives a low pressure turbine, when controlling the flow of heated steam by continuously opening/closing the main/sub flow regulating valves, hysteresis is provided so that the fully opened region of the sub flow regulating valve and the fully closed region of the main flow regulating valve are overlapped, and the sub flow regulating valve controls the flow in the hysteresis region while continuously controlling the main/sub flow regulating valves by opening/closing operation, with a single valve opening command signal being used to perform this control.

摘要： PURPOSE:To perform effective utilization of space in the nests of tubes and improve a maintenance characteristic by a method wherein at least one heating steam chamber of a first stage and a second stage heaters is stored in a barrel, the heating steam chamber is closely arranged to reduce a diameter of the barrel and the other heating device can be moved up and down with respect to a pulling of the heating device. CONSTITUTION:Discharged steam 11 from a high pressure turbine flows from an inlet pipe 9 at a lower part of a barrel and its moisture content is removed by a moisture content separator 2. After this operation, the steam is heated by a first stage heater 3 and a second stage heater 4. The steam becomes an over-heated steam and then the steam is sent from an outlet pipe 10 to a low pressure turbine. A heating steam chamber 5a of the first stage heater and a heating steam chamber 5b of the second stage heater are moved by their central positions by a size A in a longitudinal direction of the barrel. The first stage heating steam chamber 5a and the second stage heating chamber 5b are located at a position where they are overlapped by a size B in respect to a flowing direction of heated steam 11. As a required diameter of the barrel 1, it is possible to reduce it by the size B and then the barrel can be made compact. In case that it is required to pull out the first stage heater 3, the second stage heater 4 is hung upside, thereby a pulling of only the first stage heater can be performed.
