An energy and exergy analysis of a novel solid particle solar receiver is presented based on experimental data and well-known correlations found in the literature. A sand sample from the deserts of the United Arab Emirates has been chosen as the solar absorber and heat carrier material. The intent of the receiver is to be used as a part of a sensible thermal energy storage system for concentrated solar power plants based upon the concept of storing solar heat in sand particles for a later discharge through a specific sand-steam heat exchanger. The results of the analysis indicate low efficiency figures that can be caused by imperfections on the experimental setup and on the original design. Several paths of improvement are discussed in conclusion.
