Compatibility tests between Solar Salt and thermal storage ceramics from inorganic industrial wastes

摘要: Abstract This paper demonstrates the feasibility of using several post-industrial ceramics as filler materials in a direct thermocline storage configuration. The tested ceramics, coming from industrial processes (asbestos containing waste treatment, coal fired power plants or metallurgic furnaces) demonstrate relevant properties to store thermal energy by sensible heat up 1000 °C. Thus, they represent at low-cost promising, efficient and sustainable approach for storage. In present study, thermo-chemical compatibility these with conventional binary Solar Salt is medium temperature (500 °C) under steady state. order determine such material, Environmental Scanning Electron Microscopy (ESEM) X-Ray Diffraction (XRD) characterizations have been performed check their chemical structural evolution during corrosion tests. final objective develop molten salt system shaped ceramic structured material. Most an excellent resistance should significantly decrease current cost concentrated solar system.
