摘要： PURPOSE:To shorten the time for starting a plant by adjustably feeding condensate which contains the demanded quantity of the mixed oxygen into a starting condensor so as to quicken the time at which the condensate inside the starting condensor is put into the state where the condensate contains the demanded quality of mixed oxygen. CONSTITUTION:In operation of a plant, a part of the condensate inside a condensor 1 is sent into the condensate pipe 7 of a starting condensor 2 and condensate containing the demanded quantity of mixed oxygen is circulated in the plant having the starting condensor 2 and thereafter sent into it so that the condensate containing a great amount of oxygen and the condensate containing a demanded quantity of it are mixed inside the starting condensor 2, thereby greatly reducing the quantity of the oxygen contained in the condensate inside the condensor 2. Since the steam from the condensor 1 is supplied into the starting condensor 2, the condensate therein becomes excess and therefore recovered in a make-up tank 14. On the other hand, the condensate inside the condensor 1 may become lean, however, the condensate containing considerably great quantity of oxygen is additionally supplied rom a tank 14. The condensate inside the condensor 2 may become rich in the quantity of mixed oxygen to the demanded rate within a short period.
摘要翻译：目的：通过将含有所需量的混合氧气的冷凝水可调节地供入起动冷凝器，缩短启动工厂的时间，以加快启动冷凝器内的冷凝水进入冷凝水含量的时间混合氧的要求质量。规定：在工厂运行中，冷凝器1内的一部分冷凝水被送入起始冷凝器2的冷凝管7，并且含有所需量的混合氧的冷凝物在具有起始冷凝器2的设备中循环，此后送入其中，使得含有大量氧气的冷凝物和含有所需量的冷凝物混合在起始冷凝器2内，从而大大减少了冷凝器2内的冷凝物中所含的氧气的量。由于蒸汽从冷凝器1供应到起始冷凝器2中，其中的冷凝物变得过量，因此在补充槽14中被回收。另一方面，冷凝器1内的冷凝物可能变得倾斜，然而，冷凝物含有相当大的另外从罐14供给氧的量。冷凝器2内的冷凝物可能变得富含混合氧的量在短时间内要求利率。

摘要： PURPOSE: To enable the early starting of an electric power plant by a method wherein an undeaerating condensate contained in a condenser in replaced with a clean condensate in a device in which a deaerated condensate is stored, then said undeaerating condensate is supplied to a boiler.
CONSTITUTION: By arranging a condenser communicating valves 17, a condenser communicating pipe 18 and a condenser communicating regulation valves 19, a condensate inside of a starting condenser 2 can be mixed with a condensate of a condenser 1 during an operation. The condensate inside of the starting condenser 2 is flowed-back to the condenser 2 and circulated by the driving of a condensing pump 5 via a condenser circulating piping 8 and a condensate recirculating valve 9 which are branched from the condensing pipe 7 of a grand condenser 6 outlet. Further, a steam is introduced via an auxiliary steam pipe 10 and an auxiliary steam regulating valve 11, then the degree of vacuum is gradually increased with an air extractor 4. Thus, the time required for condensation and deaeration can be reduced largely, accordingly, the early starting of an electric power plant can be achieved.
