A STUDY ON NON-METALLIC STRUCTURE OF HELIOSTAT
Heliostat constitutes a very important component in the solar power tower system. Its importance derives from three aspects: one is the large proportion in the total cost, accounting for about 50％ of the whole, the other is its concentration efficiency and reflectivity heavily determining the power conversion from solar thermal energy to electrical energy, another is itself power consumption amount highly expressing failure or success of the power plant. Therefore, serious efforts and considerations from the structure, motion and control mode to material selection have to be given in the design and optimization of heliostat. In the present paper, the mechanical and aging performance of non-metallic materials is investigated and compared. The possibility of these non-metallic materials in the application of heliostat structure is discussed.
