PROBLEM TO BE SOLVED: To provide a desalination power generation plant capable of improving heat efficiency of a power generation cycle in a power generation facility, capable of reducing power of respective apparatuses, and capable of obtaining suitably refined freshwater. SOLUTION: The desalination power generation plant is constituted by the power generation facility 1 and a desalination facility 2. The power generation facility 1 is provided with a boiler 11 to which first seawater from the outside is introduced, a turbine 13 for generating the power, and a condenser 14. In the power generation facility 1, a medium for power generation is circulated and moved through the boiler 11, the turbine 13 and the condenser 14 in order. The desalination facility 2 is provided with a seawater pump 19 for feeding second seawater of which temperature is lower than that of the first seawater to the condenser 14, and a reverse osmosis membrane device 22 to which the second seawater is fed from the condenser 14. The reverse osmosis membrane device 22 separates the freshwater from the second seawater fed from the condenser 14 by a reverse osmosis membrane. COPYRIGHT: (C)2008,JPO&INPIT
