摘　　要：熔盐具有使用温度高、热稳定性强、高比热容和低饱和蒸汽压等优点,是优良的传热储能介质。工业园区通过大容量熔盐储能与供热/发电系统耦合,构建分布式储能-灵活供热供电系统,不仅可解决新能源电力大幅并网后的消纳问题,还为园区供热提供了新的发展方向。该文通过对某园区熔盐低碳供热示范项目分析,探究熔盐电加热、熔盐储能及蒸汽发生系统相关技术方案,为园区熔盐供热技术提供借鉴。Molten salt has the advantages of high operating temperature,strong thermal stability,high specific heat capacity and low saturated vapor pressure,and is an excellent heat transfer and energy storage medium.The industrial park couples large-capacity molten salt energy storage with the heating/power generation system to build a distributed energy-flexible heating and power supply system,which can not only solve the consumption problem of new energy power after being greatly connected to the grid,but also providea new development directionfor park heating.This paper analyzes a low-carbon molten salt heating demonstration project in a park,explores relevant technical solutions for molten salt electric heating,molten salt energy storage and steam generation systems,and provides reference for the park's molten salt heating technology.
