Abstract
A water purifying apparatus for purifying cooling water of a power generator includes a cooling water tank, a steam condenser, an intermediate tank, a demineralizer, a boiler and a controlling member. The controlling member receives water and ammonia added-water so as to produce a mixed cooling water. The controlling member is configured to mix water which meets a predetermined quality criterion of electrical conductivity so as to supply the mixed cooling water to the cooling water tank. The cooling water tank is configured to flow the cooling water to the intermediate tank. The intermediate tank is configured to permit the outflow of the cooling water to the steam condenser if the buoyant force produced by the cooling water is strong enough to lift a pontoon. The water purifying apparatus can purify water with less cost, and protect the power generator from copper corrosion.
