| Research Abstract |
In the development on the rotary type solar reactor, the eight-step process of the 1^<st> model of the rotary type solar reactor (1kW), which had been fabricated previously on this project, has been improved to three-step process. The 2^<nd> model of the 10kW rotary type solar reactor was designed and fabricated (the specific ; diameter of the rotor= 50cm, To_2=1500℃, concentrated beam flux=2100kW/m^2, ωt=2.5 rpm. The performance test on the 2^<nd> model was carried out using the Ni-ferrite as reactive ceramics, and 80% recovery of the released O_2 and steam for H2 generation were obtained at To_2=1250℃. The H2 generation step was not achieved because of the limitation of the maximum temperature of To_2=125O℃. The simulator for solar concentration system was developed to estimate the practical flux magnitude in the Tokyo Tech Beam-down solar concentration system (TIT-BD system) at the focus point for using the rotary type solar reactor, and the CG software was developed to express the simulation result on TIT-BD system by CG. In the development on the heliostat, GPS system as a regulation system for tracking the sun was found to be superior to the three points recognition system. In the, development on the TIT-BD system, multi-ring central reflector system, cavity type molten salt receiver, and cross-beam heliostat field design were developed.
In the development of the reactive ceramics, the solid solution system between YSZ and the ferrites has been studied and was found to be used for the two-step water splitting process using rotary type solar reactor. In test of the O_2-releasing step of rotary type solar reactor, an intermediate stage of the reactive ceramics was discovered during a rapid temperature increase by the concentrated infra-red beam irradiation to the ceramics in the O_2-releasing step in the rotary type solar reactor.
