摘　　要：吸热器在停机疏盐时,容易发生冻堵,本文通过模拟与理论计算两种手段对自然散热边界条件下熔盐温度变化过程进行分析,得出熔盐发生冻堵的原因,并从设计、运行角度给予了优化建议。Salt freezing blockage is prone to occur during the process of salt draining when the heat receiver is shutting down.Oriented to this problem,the temperature change process of molten salt under natural heat dissipation boundary condition is analyzed by simulation and theoretical calculation simultaneously.The reason of molten salt freezing blockage is given,and optimization suggestions are given from the perspectives of design and operation.
