摘　　要：设计了一种太阳能中高温热利用系统,并对系统的经济性进行了分析。同时,以槽式太阳能热发电成本为依据,对系统的投资成本和投资回收期进行了计算和分析。结果表明,太阳能中高温热利用系统的建设投资成本有望降低到650美元/kW,总投资成本有望降低到750美元/kW。对于年日照时间在2000 h以上地区,随着系统规模的扩大,投资回收期5.6～12.5 a。综合显示,太阳能中高温热利用技术具有较好的经济性。A kind of application system of solar mid-high temperature steam was designed.And economical benefits of this system were analyzed.According to cost of parabolic trough electricity system,total investment cost and payback period of this system were calculated and analyzed.The results showed that construction and total investment costs could reach to 650MYM/kW and 750MYM/kW.For areas with sunshine more than 2000 hours,payback period would be 5.6~12.5 years according to system scale.Results indicated that application of solar mid-high temperature steam had good economy.
