摘　　要：蒸汽型高温固体储热技术是将谷电或新能源富裕电力转化成热能,存储于固体储热材料内,随着工业用户工艺蒸汽需求,启动循环风机将固体储热材料内热量通过空气传递至水,水吸收热量变成蒸汽,实现用户供汽。以某制药公司为例,介绍了蒸汽型高温固体储热系统流程,结合工艺蒸汽需求和当地电价政策,采用投资决策的动态评价方法,分析了蒸汽型高温固体储热系统的净现值、内部收益率和投资回收期。通过分析可知,蒸汽型高温固体储热系统的经济性不仅受当地天然气、煤炭价格对蒸汽价格影响,同时还受谷电价格、电力市场交易价格及政府相应的支撑政策约束。Steam-operated high-temperature solid heat storage technology is to convert surplus electricity from valley power or new energy into thermal energy and store it in solid heat storage materials,and with the demand for process steam from industrial users,it starts a circulating fan to transfer the heat in the solid heat storage materials to water through air,and water absorbs the heat and turns it into steam,so as to achieve steam supply to users.This paper introduces the process of the steam-operated high-temperature solid heat storage system.Taking a pharmaceutical company as an example,combined with the process steam demand and local electricity price policy,this paper uses the dynamic evaluation method of investment decision-making to analyze the net present value,internal rate of return and pay back period of the steam-operated high-temperature solid heat storage system.Through analysis,it can be seen that the economy of the steam-operated high-temperature solid heat storage system is not only affected by the local natural gas and coal prices on the steam price,but is also constrained by valley electricity prices,electricity market transaction prices and corresponding government support policies.
