This paper presents the concept of multi-layered porous media salt gradient solar pond (MP-SGSP). The thermal behavior has been analyzed and compared with the single-layer porous media solar pond. The experiments show that: the heat storage layer (LCZ) temperature rising rate of MP-SGSP with slag plus glass balls was significantly higher than that of singlelayer porous media solar pond with slag only, and temperature drop rate was slightly lower than single-layer porous media solar pond.
