Abstract

PROBLEM TO BE SOLVED: To construct and operate a cooling system of a generator with hydrogen gas by providing a path for feeding a chlorine constituent produced in a chlorine generating device to a cooling water circulation system and a path for feeding hydrogen gas produced as a byproduct in the chlorine generating device to a cooling system of a main generator. SOLUTION: Sea water is sucked by a circulation water pump 11 so as to take water through an intake 32 and part of the sea water taken is branched at an upstream side of a condenser 12 and is supplied as raw water to a chlorine generating device 14 after pressure is boosted by a booster pump 13. Sodium hypochlorite produced by the chlorine generating device 14 is injected to an inlet side of the circulation pump 11 through a chlorine supply line 15 and miscellaneous bacteria are treated and residues produced at that time are discharged to an outlet 33. On the other hand, the chlorine generating device 14 generates hydrogen gas as a byproduct and the hydrogen gas is collected by a hydrogen gas separator 29 and is supplied to a generator 23 through a hydrogen gas supply line 24 so as to use it as a cooling medium.
