Abstract
This study experimentally investigates the heat release performance of a single-tank molten salt storage system that utilizes a straight-tube heat exchanger.The study analyzes temperature variation patterns during heat storage,heat release,and static cooling processes.The experiments reveal that when the fan operates at full power,the system achieves a maximum heat release power of 63.7 kW,an average heat release power of 46 kW,and an overall heat release efficiency of 88%,allowing it to heat cold water from 27℃to 64.4℃.During the heat release phase,the temperature distribution of the molten salt is generally uniform.However,near the air inlet,the temperature drops more rapidly due to intense local heat exchange.In the 12 h static cooling phase,the molten salt temperature decreases linearly by a total of 36.8℃,with an average cooling power of 4.8 kW.Notably,significant vertical temperature stratification is observed,with a maximum temperature difference of 16.8℃.This study provides experimental evidence supporting the use of straight-tube heat exchangers in single-tank molten salt storage systems and offers valuable insights for regional heating and industrial heat storage engineering design.关键词
