Title:
DEVICE AND METHOD FOR COOLING STEAM CONDENSER
Document Type and Number:
Japanese Patent JP2014206312
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a device and method for cooling a steam condenser that can eliminate leakage of seawater even if cracking such as a clearance, a crack, and a pin hole is generated on cooling water condenser tubes of the steam condenser.SOLUTION: A device for cooling a steam condenser includes: an introduction passage 12 for introducing cooling water 11; an inlet water chamber 13 connected to the introduction passage 12 to introduce the cooling water 11; the steam condenser 18 having a plurality of cooling water condenser tubes 17 through which the cooling water 11 introduced from the inlet water chamber 13 passes and that cool steam 15 from a steam turbine 14 to produce steam condensate 16; a water chamber 19 for steam condensate that is installed at the bottom of the steam condenser 18 to store the steam condensate 16; an outlet water chamber 20 for discharging the cooled cooling water 11 from the cooling water condenser tubes 17; a discharge passage 21 connected to the outlet water chamber 20 to discharge the cooling water 11; and an intake pump Pinterposed in the discharge passage 21 to decompress and suck the cooling water 11.
