的に復水流出孔7から復水器外部に流出する。2. Description of the Related Art A condenser has a lower pressure than the atmosphere and leaks non-condensable gas such as air. It is important to extract the non-condensable gas to the outside of the condenser, because if the non-condensable gas accumulates, the condensation in the cooling pipe is hindered. Figure 3 shows the structure of the condenser. The steam from the turbine is condensed in the tube nest 4, and the non-condensed gas and the uncondensed steam are extracted from the air extraction pipe. In order to further condense the uncondensed vapor to lower the pressure of the air extraction pipe and improve the extraction capacity, the air cooling chamber 1 is provided in a part of the cooling pipe in the pipe axial direction. The air cooling chamber 1 raises the mixed gas of the non-condensable gas and the unvaporized vapor to separate the condensate and the non-condensable gas that fall due to gravity, and the cooling pipe 2 of the air cooling chamber 1
The structure will condense uncondensed steam. Air cooling room 1
The condensate condensed in (1) drops downward, passes through the air extraction pipe, and finally flows out from the condensate outflow hole 7 to the outside of the condenser.

保てる。The simplest method of preventing condensed water from accumulating in the air extraction pipe is to provide a condensate outlet separately from the air extraction pipe. On the other hand, the function of the air cooling chamber is to condense uncondensed vapor from the air extraction pipe and keep the inside of the air extraction pipe at a low pressure. If the condensate outlet is provided separately from the air extraction pipe, the pressure cannot be kept low because it is connected to the outer side of the air extraction pipe having a high pressure. In the present invention,
We focused on the condensate generated in the air cooling room. That is, if the condensate outlet is a downwardly directed thin tube, the condensate is held in the tube by a certain amount due to surface tension, and only the condensed water that has condensed within a certain time flows out. Condensate held in the capillaries can always block the capillaries against steam and keep the pressure low.

Condensate held in the capillaries can always block the capillaries against steam and keep the pressure low.

The non-condensable gas and the unvaporized steam flow into the air cooling chamber from the air extraction hole 12 provided in the vertical partition wall 10 separately from the thin tube 11 in the cross section and from the air extraction tube in the tube axis direction. Condensate produced by condensation in the upper cooling pipe 2 falls to the lower part of the air cooling chamber, but is held in the thin pipe 11 by a certain amount due to surface tension, and only condensate condensed within a certain time flows out by gravity. Although it is necessary to make the thin tube 11 thick in order to reliably discharge the condensate to the outside of the room, the condensate held in the thin tube 11 can always block the thin tube against steam and keep the pressure low. . When the thin tube 11 is made thicker so that it cannot hold the condensate due to the surface tension, the same effect can be obtained by bending the thin tube 11 into an S shape to form a pool of condensate as shown in FIG. 1B. .
