  • Solar heat boiler and solar heat electric power generation plant
    Patent number: 9605662
    Abstract: A solar heat boiler is provided which is capable of avoiding damage to heat transfer tubes without increasing facility cost and construction cost. The solar heat boiler includes: a low-temperature heating device by which water supplied from a water supply pump is heated by heat of sunlight; a steam-water separation device by which two-phase fluid of water and steam generated in the low-temperature heating device is separated into water and steam; a high-temperature heating device by which the steam separated by the steam-water separation device is heated by the heat of sunlight; and a circulation pump by which the water separated by the steam-water separation device is supplied to the low-temperature heating device.
