Steam condensing device in power plant

Abstract

Abstract PURPOSE:To equalize a discharging water temperature with a sea water temperature in shallow sea by a method wherein a water intaking system from deep sea having lower temperaure is provided in parallel to the intaking system from the shallow sea, in the power plant condensing the steam by intaking the sea water from the shallow sea. CONSTITUTION:As a water feeding route for a condenser 5, the route of a pump 8, having a water intaking port 7 in the shallow sea and interposed with an opening and closing control valve 9, and the route of the pump 11, having the water intaking port 10 in the deep sea, in which the sea water temperature is lower than the same in the shallow sea, and interposed with the opening and closing control valve 12, are provided. Temperature detectors 13, 14 are arranged at the water discharging side of the condenser 5 and the proximity of the water intaking port 7 while a temperature difference detector 15, detecting the temperature difference, is provided. When the temperature of the discharging water of the condenser 5 has increased to a temperature higher than the sea water temperature in the shallow sea near the water intaking port 7, the temperature difference between temperatures of both seas is detected by the detector 15 and the opening degree of the control valve 9 is decreased to reduce the amount of intaking water from the shallow sea, while the opening degree of the control valve 12 is increased at the same time to increase the amount of intaking water from the deep sea, whereby, the discharging water temperature from the condenser 5 is reduced relatively to control automatically the temperature variation in the shallow sea, into which the discharging water is released, so as to reduce said variation.
