    • A moisture separator/heater that removes moisture from highly moist steam and heats the steam from which the moisture has been removed to produce superheated steam is provided. The moisture separator/heater includes a cylindrical main shell, a moisture separator that removes moisture in steam to be heated that flows in through the bottom of the main shell, and a heater disposed above the moisture separator in the main shell. A plurality of restricting members are disposed in a heating space in the moisture separator/heater so as to sandwich a tube bundle side plate with an outer rail to restrict rounded-back deformation thereof and are disposed so as to satisfy an expression of 0.2≦L1/L and L2/L≦0.4, where L represents the total length of a straight tube portion, L1 represents the distance from one of the pad members that is closest to a steam heating header to an end of the straight tube portion on the side where the steam heating header is present, and L2 represents the distance from one of the pad members that is closest to a curved tube portion to an end of the straight tube portion on the side where the curved tube portion is present. The thus configured moisture separator/heater allows a leak path between an inner rail and the outer rail can be made sufficiently narrow irrespective of the length of a heat-transfer tube.
    • 提供了一种从高湿度蒸汽中除去水分并加热已除去水分以产生过热蒸汽的蒸汽的水分分离器/加热器。 湿气分离器/加热器包括圆柱形主壳体,除湿器,其去除通过主壳体的底部流入的被加热的蒸汽中的水分,以及设置在主壳体中的湿气分离器上方的加热器。 多个限制构件设置在湿气分离器/加热器的加热空间中,以便将具有外轨的管束侧板夹在中间以限制其倒圆的变形,并且设置成满足0.2< nlE的表示; L1 / L和L2 / L≦̸ 0.4,其中L表示直管部分的总长度,L 1表示距离蒸汽加热集管中的最靠近蒸汽加热集管的衬垫构件之一到直管部分的一端的距离 其中存在蒸汽加热集管的一侧,L2表示从弯曲管部分最靠近的一个焊盘部件到存在弯曲管部分一侧的直管部分的一端的距离。 如此构成的水分分离器/加热器允许内导轨和外轨之间的泄漏路径被制成足够窄,而不管传热管的长度。

    • A feed water heater has a longitudinally cylindrical body comprising a cylindrical shell portion constituting a main body portion of a feed water heater and a water box-shaped chamber operatively connected to the cylindrical shell portion and partitioned by a tubesheet. In the cylindrical shell portion, a heat exchanger tube bank is arranged and supported by a plurality of support plates, a drain cooling section is disposed in association with the heat exchanger tube bank for carrying out a heat recovery of a drain generated in the heat exchanger tube bank, a dilution condensing chamber is provided for the heat exchanger tube bank and adapted to excessively flow the steam into the heat exchanger tube bank, and a non-condensable gas chamber is provided for the heat exchanger tube bank. The drain cooling section, the dilution condensing chamber and the non-condensable gas chamber are arranged axially in this order in the cylindrical shell from the tube sheet.
    • 给水加热器具有纵向圆柱形主体,该主体包括构成给水加热器的主体部分的圆筒形壳体部分和可操作地连接到圆柱形壳体部分并由管板分隔的水箱形室。 在圆筒形壳体部分中,热交换器管组由多个支撑板布置和支撑,排水冷却部分与热交换器管组相关联地设置,用于对热交换器中产生的排水进行热回收 管排,为热交换器管堤提供稀释冷凝室,适于使蒸汽过度流入热交换器管堤,并为热交换器管堤提供不可冷凝的气室。 排水冷却段,稀释冷凝室和不可冷凝气体室从管板沿轴向依次布置在圆筒形壳体中。
