Study on Design of Cavity Receiver of Concentrating Solar Power Plants—A Review

Conference paper
Part of the Springer Proceedings in Energy book series (SPE)

Abstract

The concentrating solar power technology has achieved rapid development in the world. One of the important components of such technology is cavity receiver as it affects the efficiency of the entire power plant. The solar cavity receiver is a photo-thermal conversion component of solar power plants, which heats the working fluid contained in it by absorbing solar radiation. In this paper, an effort has been made to review the work carried out by various researchers on different cavity receiver designs. Based on literature survey, it has been found that cavity geometry has a significant effect on overall flux distribution. The effect of rotation has been observed to be less than 1% for overall receiver efficiency calculations. The thermal losses occurring from the cavity receiver have been found to be affected by various parameters like thermal emissivity, mean fluid temperature, opening ratio and receiver inclination. The wind direction and fluid flow rate also have a considerable influence on the thermal performance of the cavity receiver. It has been realized that there is still scope for developing designs of an efficient cavity receiver which could minimize the losses and hence, enhances the overall efficiency of the plant. The identified gaps in this area for further research have also been discussed in this paper.
