PROBLEM TO BE SOLVED: To solve a theme for manufacturing metallic sodium applied for alternative energy in place of fossil fuel under utilization of waste heat occupying approximately 50% of a thermal power plant while keeping a cooling effect irrespective of uneconomical state not utilizing abundant heat stored medium as well as tremendous amount of influence of this large amount of hot water discharged into the sea after sea water of 40 tons per 1 second is increased by 7°C and discharged into the sea so as to get an electrical power of 100 MW at a thermal power plant.SOLUTION: Tubules in a condenser through which cooling sea water circulates are divided into an upper circuit and a lower circuit, a speed of brine flowing in the upper circuit is delayed to increase heat storage amount for sea water and make high temperature sea water, then distilled water and concentrated seawater are efficiently recovered. The concentrated seawater is used for manufacturing metallic sodium under application of waste heat of a power plant, surplus electrical power and midnight power and so energy resources can be recovered. |
