摘要

提升煤电机组灵活性是实现绿色低碳电力系统的关键。熔盐储能技术作为一种显热储能技术，可为发电机组提供调频、调峰及工业供热解耦支持。结合某电厂熔盐储能耦合燃煤机组的工程应用，系统分析了储热、释热与能量循环的热力性能，提出了性能评估指标。结果表明，熔盐储热系统显著增强了机组灵活运行能力，实现了工业供汽与机组深调和顶峰的解耦，同时调频性能提升了150%，储热系统热效率维持在92%左右。该研究结果为基于熔盐储热技术的燃煤电站灵活性改造工程应用提供了参考。

Abstract

Improving the flexibility of coal-fired power units is the key to achieving a green and low-carbon power system. Molten salt energy storage technology

as a sensible heat energy storage technology

can provide frequency regulation

peak regulation

and industrial heating decoupling support for power generation units. Combining with the engineering application of a coal-fired power unit coupled with molten salt energy storage

the thermal performance of heat storage

heat release and energy cycling are systematically analyzed

and performance evaluation indicators are proposed. The results show that

the molten salt thermal storage system significantly enhances the flexible operation capability of the unit

achieves decoupling between industrial steam supply and deep commissioning peak of the unit

and improves the frequency regulation performance by 150%. The thermal efficiency of the thermal storage system is maintained at around 92%. This study provides a reference for the application of flexibility renovation projects for coal-fired power plants based on molten salt thermal storage technology.
