  • Patent number: 8647416
    Abstract: A superheated steam generator for generating superheated steam is disclosed that can be converted into electric energy by adsorbing water into zeolite and desorbing water from zeolite by use of solar heat source energy and seawater source energy. The superheated steam generator using zeolite is provided with a water supply device for causing the zeolite to adsorb mist-state moisture and heat the zeolite, a zeolite boiler system including a desorption heater for desorbing water molecules adsorbed onto the zeolite and heating the zeolite to produce the superheated steam, a low-temperature purified water tank for storing purified water that can be subjected to heat exchange with at least one of seawater and surface water, and for supplying purified water energy subsequent to the heat exchange to the water supply device, and an atomization device for generating the purified water supplied to the water supply device as the mist-state moisture.
