摘要： PURPOSE:To improve the water level controllability and operability by constituting the cylinder section of a deaerator of a single lateral cylindrical pressure vessel and making its upper half section a deaeration chamber and its lower half section a condensate storage tank and providing a deaeration device in the deaeration chamber and a deflecting device in the condensate storage tank. CONSTITUTION:The condensate flows into a deaeration chamber 3 at the upper half of a pressure vessel through a plurality of multiple water injection valves 1 from a condensate inlet seat 7, and the condenate is atomized while it drops through a deaeration tray 2 and at the same time the condensate is heated to the saturation temperature at the pressure in the vessel of the deaeration chamber 3 by heated steam which flows from a heated steam inlet seat 8. The oxygen dissolved in the condensate is thereby deaerated to the concentration required in the water through boiler, and the uncondensed gas containing dissolved oxygen that is deaerated from the condensate is discharged to the atmosphere through an exhaust pipe 13 that is provided at the upper section of the deaeration chamber 14. On the other hand the condensate which is deaerated in the deaeration chamber 3 falls freely into a water storage tank 4 and the condensate of the quantity required for supplying water to the boiler stably is stored in the water storage tank 4. With this arrangement the water level controllability and operability are improved and the assembly weight is reduced.

摘要： PURPOSE:To improve an effect of washing a heat transfer pipe, by a method wherein washing ball bodies floating in sea water and washing ball bodies sunk in sea water, which are mixed approximately in a ratio of by half half, are fed to each heat transfer pipe of a condenser. CONSTITUTION:A first washing body is formed with a core 11 formed by a material having a specific gravity lower than that of sea water and an outer skin 12, with which the core 11 is covered and which is formed in a spherical shape. Meanwhile, the same ball as a conventional one is used as a second washing body, and the two types of the balls are mixed approximately in the same quantities as each other. The first and the second ball, containing quantities of water, are fed to a ball pouring device 8 of a ball washing device together with sea water to pour them in an intake pipe 1. In this case, since the core 11 part of the first washing ball body has a sepcific gravity lower than that of sea water, it flows in a state to be deviated in a position above the intake pipe 1. Meanwhile, since the second washing ball bodies have approcimately the same sepcific gravity as that of sea water, a most of the ball bodies flow in a state to be sunk on the bottom of the intake pipe 1. This constitution causes the washing ball bodies to uniformly disperse in heat transfer pipes 5a and 5b of condensers 2a and 2b, respectively.
