Experimental Study on Electric Heating Single-Tank Molten Salt Thermal Energy Storage Heating Device

摘要: 在全球能源转型的背景下，储能技术的研究愈发重要。本次测试针对河北永昕锅炉有限公司生产的相变熔盐储能罐，旨在测量其在充放电工况及自然散热下的温度分布、热交换效率和电功率消耗情况。通过高精度的温度传感器、风速仪和数据采集系统，测试分为储能阶段、释能阶段和自然冷却阶段，记录了熔盐罐内外的温度变化、风速及能耗数据。结果表明，熔盐罐在储能和释能过程中存在一定的热损失，且保温性能有待提升。基于测试数据，提出了优化熔盐加热温度、降低出风温度及改进储能罐结构的建议，为进一步提高储能罐的性能提供了参考依据。

Abstract: Against the backdrop of the global energy transition, the research on energy storage technologies has become increasingly important. This test focuses on the energy storage molten salt tank produced by Hebei Yongxin Boiler Co., Ltd., aiming to measure its temperature distribution, heat exchange efficiency, and electric power consumption under charging and discharging conditions, as well as during natural heat dissipation. By using high-precision temperature sensors, anemometers, and a data acquisition system, the test is divided into three stages: the energy storage stage, the energy release stage, and the natural cooling stage. The temperature changes inside and outside the molten salt tank, wind speed, and energy consumption data are recorded. The results show that there are certain heat losses during the energy storage and release processes of the molten salt tank, and its thermal insulation performance needs to be improved. Based on the test data, suggestions such as optimizing the molten salt heating temperature, reducing the outlet air temperature, and improving the structure of the salt storage tank are put forward, providing a reference for further enhancing the performance of the energy storage molten salt tank.
