PURPOSE:To improve the durability of the condenser by a method wherein internal members such as cooling tubes and the like are protected from being damaged by flash steam containing drainage even when the drainage accompanied by the generation of a large amount of the flash steam is introduced in the condenser. CONSTITUTION:After being separated the drainage, the flash steam goes upward and is led through an upper opening 38 into the condenser 20. In this case, because the area of the upper opening 38 is enough large, no choking of the flash steam is developed and the flow speed of the steam jetting out of the upper opening 38 turns to be small. On the other hand, the drainage separated from the flash steam goes downward and falls down below the surface of the water in a separating chamber 37 and, after that, is led through a ower opening 39 to the hot well 23 of the condenser 20. In this case, due to the structure that the lower opening 39 locates below the surface of the water in the hot well 23, no stream flows through the lower opening 39, resulting in preventing the structure within the condenser from being damaged by the outflowing drainage. |
