高温固体储热材料热稳定性研究
Study on Thermal Stability of High-Temperature Solid Thermal Energy Storage Materials
摘要
Abstract
Thermal energy storage materials made from rocks and rock-based raw materials can serve as an ideal sensible heat storage medium,and have been applied in experimental studies on high-temperature thermal energy storage in packed beds for solar thermal power generation.Solid thermal storage materials are required to exhibit high thermal resistance,high specific heat capacity,high stability,and low cost,with natural rocks and ceramic materials derived from natural rocks being the primary choices.This study investigates natural rocks and artificially manufactured solid thermal storage materials,obtaining key thermophysical property data such as specific heat capacity and thermal shock resistance of rock-based solid storage materials.Experimental results indicate in the context of ultra-high temperature molten salt thermal storage at 700℃,basalt and alumina-silicate pellets demonstrate superior thermal stability.关键词
