A particle receiver for the beam-down solar concentrator was developed in this laboratory. This study aims to increase temperature and improve the heat storage efficiency of the developed receiver. In general, a receiver heats heat mediums such as steam, molten salt, or air. The heated mediums are sent to generation systems such as steam turbines and/or heat storage systems. Alumina balls are used as heat mediums for the receiver; they are heated directly by sun light, and they store this thermal energy as sensible heat. Experiments were conducted using the beam-down solar concentrator with the compound parabolic concentrator (CPC) and the particle receiver. This study revealed that the heating medium was heated up to 1570°C using the receiver. It was found that the quartz glass was effective in reducing heat loss, but the enclosure proved to be less effective. The temperature distribution depended on the distance from the CPC. It was also observed that the distance between the CPC and the receiver does not affect the heat storage efficiency significantly.}, pages = {49--54}, title = {ビームダウン式太陽集光装置のための固体攪拌型蓄熱装置の改良}, volume = {47}, year = {2018}, yomi = {マエダ, ナオト and ナガセ, ヨシノリ and トモマツ, シゲキ and アンザイ, シンタロウ and キムラ, マサトシ and マエダ, ナオト and アンザイ, シンタロウ} }
