Thermal Performance of a Quartz Tube Solid Particle Air Receiver

AbstractIn this article, an innovative solid particle receiver was developed which suitable to be used as fluidized bed solar receiver. The receiver is composed of five quartz tubes with the flowing silicon carbide particles as absorber. The thermal performance of the receiver was tested using 10kWth solar furnace system in Badaling solar thermal power experimental platform of China. Three days experimental results are listed in this paper. The maximum outlet air temperature is 624.1°C. The minimum temperature difference between particles and outlet air is below 10°C which shows good heat ransfer performance inside the receiver. The experimental results well verified the technical feasibility of such receiver design
