摘要： Water quality detecting points for detecting sea water leakage are provided at a portion in a hot well zone right under a tube bundle of heat exchange tube forming a steam condensing zone and at a condenser outlet allowing the condensate to be led out of the condenser or in the vicinity thereof, and a difference between detection values at both detecting points is monitored. Further, when leakage of sea water occurred, a feed water stop valve or a condensate stop valve is stopped for separating the system in which the sea water is mixed, and at same time, make-up water is supplied to a steam generator. Further, chemical or chemical dilution water is injected into the condensate mixed with sea water.

摘要： A condenser for use in a power plant includes a steam condensing zone having a heat exchanger tube bundle for condensing steam into condensate and a hot well zone allowing the condensate to stay therein. A plurality of detectors for detecting the quality of the condensate and/or detection ports for taking out a sample of the condensate are provided in the hot well zone. The control valve is provided on a feed water system for adjusting the supply of the condensate to be supplied from the condenser to the feed water system on the basis of water quality detection values detected by the plurality of detectors and/or detection ports and a make-up water system is provided for supplying make-up water to the feed water system on the downstream side of the control valve.
