SATURATED STEAM GENERATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a saturated steam generating device which is provided with a heating source that generates saturated steam by heating stored water and can be reduced in size. SOLUTION: This saturated steam generating device generates saturated steam by heating water with superheated steam obtained by superheating water in a heat transfer tube 16 inserted into a thermal storage tank 10. In the tank 10, an electric heater 44 which heats a solid thermal storage material and a liquid thermal storage material and the heat transfer tube 16 are provided in a thermal storage section filled up with the solid and liquid thermal storage materials. The saturated steam generating device is also provided with a saturated steam generating tank 12 which generates the saturated steam by heating the stored water 22 by using the superheated steam obtained through the heat transfer tube 16 as the heating source.
