Abstract

To minimize the re-radiation loss emitted from the solar receiver,a double-layer solar receiver that comprises quartz glass perforated plates and silicon carbide porous material was designed,manufactured,and experimentally tested.The proposed double-layer solar receiver can achieve an increasing absorption effect and improve thermal efficiency.Results show that the double-layer solar receiver offered 10% more efficiency than the single-layer porous solar receiver through the re-radiation recycling of the quartz glass perforated plates.The mass-weighted averaging outlet temperature of the working fluid approximates 300 K higher than the inlet wall temperature of the quartz glass perforated plates,leading to a significant volumetric effect.Moreover,the heating up time of the solid phase was about 20 minutes,while the working fluid needed 50 minutes to get the steady state.The conclusions support developing porous volumetric solar receivers in advanced power cycles.
