Advances in Solid Particle Solar Receivers for the Next-generation Concentrated Solar Power Plants
The use of chemically inert solid particles as the heat transfer fluid and thermal energy storage(TES)materials in the next-generation concentrated solar power(CSP)plants will enable the solar receiver system and TES system to operate at temperatures over 800 ℃,which is expected to substantially increase the average annual power generation efficiency of CSP plants,and thus reduce the levelized cost of electricity.Solid particle solar receiver(SPSR)is the key equipment,and various schemes have been proposed by domestic and international research teams.This paper classifies various SPSR technologies according to different particle flow modes and provides a detailed introduction to the research progress of various SPSR technologies,focusing on optimizing SPSR structures and particle flow characteristics to enhance the thermal performance of the SPSRs.Combined with their operational characteristics,the technical challenges faced are also summarized through the comparative analysis of the thermal performance parameters of various SPSRs,and the corresponding optimization strategies are proposed to guide the optimal design of SPSRs.
