In recent years, renewable energy has been focused because of global warming and depletion of fossil fuels. Especially solar thermal power generation has advantages, since the energy source is the sun that is possible to secure a semi-permanently clean energy source. Furthermore, electricity can be generated even night by stored heat. In this laboratory, study of solar thermal power generation using a beam-down solar concentrator has being conducted. Studies of solar thermal storage devices that stored heat in alumina particles as thermal storage materials have been conducted and their characteristics have gradually been known. Therefore, it is necessary to consider a method for extracting the stored thermal energy. In this study, we designed and fabricated a compact model of a steam generator that generates steam by contacting water and thermal storage materials that has stored heat, and investigated its characteristics. As a result, the increase generated steam per unit time in proportion to the increase in the cross-sectional area of the steam generator.
