    • Provided are a pressure bulkhead (4) that has a plurality of holes (8) and that divides a low-pressure chamber (2) at low pressure in a vertical direction; a cooling-tube bank (5) that is provided in an upper section of the low-pressure chamber (2) partitioned by the pressure bulkhead (4) and that performs heat exchange with low-pressure steam guided to the low-pressure chamber (2) by coolant introduced therein so as to condense the low-pressure steam to low-pressure steam condensate; a reheat chamber (6) that serves as a lower section of the low-pressure chamber (2) partitioned by the pressure bulkhead (4) and that stores the low-pressure steam condensate falling from the holes in the pressure bulkhead (4); high-pressure-steam introducing means (11) for introducing high-pressure steam within a high-pressure chamber (22) at high pressure to the reheat chamber (6); and a plurality of plate members (10) that are arranged parallel to each other below the pressure bulkhead (4) and that extend in a falling direction of the low-pressure steam condensate falling from the holes (8) in the pressure bulkhead (4). The plate members (10) each have a cross-sectional shape, as sectioned in the falling direction of the low-pressure steam condensate, having one or more protrusions and recesses.
    • 本发明提供一种耐压隔壁(4),该耐压隔壁(4)具有多个孔(8),并且将低压室(2)在垂直方向上分成低压, 设置在被所述耐压隔壁(4)隔开的所述低压室(2)的上部的冷却管堤(5),其与被导入所述低压室的低压蒸汽进行热交换 2)通过引入其中的冷却剂将所述低压蒸汽冷凝成低压蒸汽冷凝物; (4)分隔的低压室(2)的下部的再加热室(6),其存储从压力隔壁(4)的孔中落下的低压蒸汽冷凝液; 高压蒸汽引入装置(11),用于将高压室(22)中的高压蒸汽以高压引入再热室(6); (4)的下方相互平行地配置,并且从压力隔壁(4)的孔(8)落下的低压侧冷凝水的落下方向延伸的多个板部件(10) )。 板构件(10)在低压蒸汽冷凝物的下降方向上具有截面形状,其具有一个或多个突起和凹部。
