Patent number: 10578341Abstract: A dual-cavity method and device for collecting and storing solar energy with metal oxide particles. Solar radiation irradiates into a light receiving cavity of a dual-cavity, heat-collecting reactor to heat a separating plate and preheat metal oxide particles. The preheated metal oxide particles then enter a reacting cavity. As temperature increases, the metal oxide particles reduce to release oxygen, which discharges through a gas outlet. Reduced metal oxide particles discharge through a particle outlet into a particle storage tank, and then into an oxidation heat exchanger to react with the discharged oxygen discharged to release and transfer stored chemical energy to a medium to be heated. The oxidized metal oxide particles are conveyed into a storage tank, and again enter into a particle inlet of the light receiving cavity. Ambient air controls the gas flow rate in the reactor and the reacting rate in exchanger.Type: GrantFiled: December 12, 2014Date of Patent: March 3, 2020Assignee: ZHEJIANG UNIVERSITYInventors: Gang Xiao, Tianfeng Yang, Mingjiang Ni, Zhongyang Luo, Xiang Gao, Kefa Cen, Mengxiang Fang, Jinsong Zhou, Zhenglun Shi, Leming Cheng, Qinhui Wang, Shurong Wang, Chunjiang Yu, Tao Wang, Chenghang Zheng

Patent number: 10533494Abstract: A solar chemically recuperated gas turbine system includes an exhaust-gas reformer, a solar reformer and a gas turbine unit with a combustion chamber. The reaction outlet of the exhaust-gas reformer is connected to the inlet of the solar reformer, the flue gas side inlet of the exhaust-gas reformer is connected to the exhaust-gas outlet of the gas turbine. The solar reformer outlet is connected to the combustion chamber inlet. Combustion gas drives the gas turbine after fuel burns in the combustion chamber, and the exhaust gas enters the exhaust-gas reformer. Fuel and steam are mixed and enter the reaction side of the exhaust-gas reformer through a fuel inlet. A reforming reaction between the fuel and steam under heating of the exhaust gas generates syngas. A further reforming reaction occurs by absorbing concentrated solar energy after the syngas enters the solar reformer, and the reactant is provided to combustion chamber.Type: GrantFiled: April 17, 2017Date of Patent: January 14, 2020Assignee: Zhejiang UniversityInventors: Gang Xiao, Tianfeng Yang, Mingjiang Ni, Zhongyang Luo, Xiang Gao, Kefa Cen, Mengxiang Fang, Jinsong Zhou, Zhenglun Shi, Leming Cheng, Qinhui Wang, Shurong Wang, Chunjiang Yu, Tao Wang, Chenghang Zheng
