Zusammenfassung:PURPOSE:To increase power generating efficiency remarkably by providing a hot heater for further heating vapor produced by heat of collected light, a solar light collector for heating the hot heater, and a re-generative heat exchanger for pre-heating water supply for vapor. CONSTITUTION:In a solar thermal power generating plant, vapor is generated from water by collecting solar light 1 injected onto a light collector 22 and a steam turbine 5 is rotated by the vapor to generate power by a power generator 6. Then the vapor is cooled and condensed by cooling water 8 in a condensor 7 to return it back to water. In this case, a re-generative heat exchanger 9 for heating water supply by exhaust gas from the steam turbine 5 is provided, the water heated by the exchanger 9 is fed to an evaporator 31 by a water supply pump 4 and is heated and vaporized by solar light 1 collected by a light collector 21. Saturated vapor in a hot heater 32 is heated by the solar light 1 collected by a parabolic light collector 22 to supply it to the steam turbine 5.
