分级冷凝的工作过程是:蒸汽从两个或更多的汽轮机排汽口排出,并在不同的绝对压力下进行冷凝,而冷却水是逐级通过诸凝汽器级的。工作过程的名称反映了分级冷凝的物理本质,因此,分级冷凝已成为最常用的术语。两级凝汽器在结构上的唯一复杂之处是设置一台使凝结水从第一级凝汽器到第二级凝汽器的溢流装置,凝汽器的级数序号是按冷却水流过的先后来排列的。因为凝汽器级本身是由冷凝装置的壳体、或者中间水室、或者挡板所构成,而这些在单壳体凝汽器里也是具有的。
The process of fractional condensation is such that steam is discharged from two or more turbine exhaust ports and is condensed at different absolute pressures and the cooling water is passed through the condenser stages in stages. The name of the work process reflects the physical nature of fractional condensation and, therefore, fractional condensation has become the most commonly used term. The only structural complexity of the two-stage condenser is the provision of an overflow device for condensate from the first stage condenser to the second stage condenser. The stages of the condenser are numbered according to the cooling water flow To arrange in succession Because the condenser stage itself is made of a condensing device housing, or an intermediate water chamber, or a baffle, these are also provided in single-shell condensers.
