Electric heat storage technology is an important approach to promote the utilization of electric energy, which has a broad prospect in the aspects of deep peak shaving, improving the utilization rate of new energy and protecting environment. In order to explore the adaptability of heat storage in steam heating, molten salt heat storage system and solid heat storage system are designed and compared based on specific engineering project. An optimal design scheme of molten salt heat storage system is put forward, and comparison is conducted from the aspects of system performance, economy and reliability. The result shows that, the proposed optimization scheme is beneficial to save investment, save space and simplify the system. For the electric energy storage heat supply station with simutaneous heat storage and heat discharge working conditions, the molten salt heat storage mode it is recommended, which is more stable for steam generation. Although the molten salt heat storage system is more complex and the total investment is slightly higher, it has higher heat exchange efficiency, lower power consumption, lower operating cost and higher income. If the total investment can be further reduced, molten salt heat storage technology will become the most competitive clean heating method in heat storage.

电蓄热技术在电网深度调峰、提高新能源利用率、改善环境方面前景广阔,是促进电能替代的重要手段。为探究蓄热技术在蒸汽供热方面的适应性,结合具体工程,对熔盐蓄热系统与固体蓄热系统进行了设计研究、对比,提出了熔盐蓄热系统设计的优化方案,并从系统性能、经济性和可靠性方面做了对比。结果表明:所提出的优化方案有利于节省投资、节约占地、简化系统;对于存在边蓄热边放热工况的电蓄能供热站,推荐采用熔盐蓄热方式,更有利于蒸汽发生的稳定;熔盐蓄热系统虽较复杂,总投资也略高,但其换热效率较高,耗电量较省,运行成本较低,收益更高。若可以进一步降低总投资,熔盐蓄热技术将成为传热蓄热方面最具竞争优势的清洁供热方式。

电蓄热技术在电网深度调峰、提高新能源利用率、改善环境方面前景广阔,是促进电能替代的重要手段。为探究蓄热技术在蒸汽供热方面的适应性,结合具体工程,对熔盐蓄热系统与固体蓄热系统进行了设计研究、对比,提出了熔盐蓄热系统设计的优化方案,并从系统性能、经济性和可靠性方面做了对比。结果表明:所提出的优化方案有利于节省投资、节约占地、简化系统;对于存在边蓄热边放热工况的电蓄能供热站,推荐采用熔盐蓄热方式,更有利于蒸汽发生的稳定;熔盐蓄热系统虽较复杂,总投资也略高,但其换热效率较高,耗电量较省,运行成本较低,收益更高。若可以进一步降低总投资,熔盐蓄热技术将成为传热蓄热方面最具竞争优势的清洁供热方式。

Electric heat storage technology is an important approach to promote the utilization of electric energy, which has a broad prospect in the aspects of deep peak shaving, improving the utilization rate of new energy and protecting environment. In order to explore the adaptability of heat storage in steam heating, molten salt heat storage system and solid heat storage system are designed and compared based on specific engineering project. An optimal design scheme of molten salt heat storage system is put forward, and comparison is conducted from the aspects of system performance, economy and reliability. The result shows that, the proposed optimization scheme is beneficial to save investment, save space and simplify the system. For the electric energy storage heat supply station with simutaneous heat storage and heat discharge working conditions, the molten salt heat storage mode it is recommended, which is more stable for steam generation. Although the molten salt heat storage system is more complex and the total investment is slightly higher, it has higher heat exchange efficiency, lower power consumption, lower operating cost and higher income. If the total investment can be further reduced, molten salt heat storage technology will become the most competitive clean heating method in heat storage.
