Optimal Design of HFC Solar Plant by Using Phase Change Material for Heat Storage

Abstract:

This paper deals with an optimal design solar tower power plant. Special attention is focused on the central receiver system and heat storage materials. In order to get an effective power plant, a simple mathematical model to calculate the solar energy, concentrated on the solar receiver during one year, is developed. The model can predict the delivered energy in dependence on the arrangement of the heliostats and the height of the solar receiver. By using an optimizer, a plant of 5 MW power is optimized in order to produce a maximum of electrical energy during the year on the prescribed area. On the basis of analysis of heat storage materials, KNO₃, acting as phase change material (PCM), is shown to be suitable for heat storage from the thermal, physical, kinetic, chemical, and economic point of view.
