Outline of Final Research Achievements

This study develops the fluidized bed solar receiver for efficient solar power generation. Since the solar receiver / reactor development project found that the cylindrical fluidized bed irradiated by concentrated light could increase the air and the particle temperature beyond 1000℃, this study deals development of numerical simulation methodology on fluidized bed and the experiment on irradiated fluidized bed with organized circulation, to propose new type of fluidized bed receiver. This new type fluidized bed receiver is based on the two-tower fluidized bed receiver which causes the organized circulation of particles by the aeration velocity difference between two towers. It was designed so that the particle can continuously enter and exit the receiver part. The experimental visualization revealed that the new fluidized bed can charge and discharge the particles continuously, to prove its applicability to the solar receiver / storage system.
