中文摘要英文摘要

光热发电中的二次反射塔式技术具有高聚光比、低泵耗和安装维护要求低等优点,依托玉门鑫能第一电力有限公司 50 MW二次反射塔式电站建立了定日镜场、二次反射模、吸热器、熔盐储罐和发电循环等关键部件模型,并完成了模型验证.运行测试结果表明:当直射辐射为 739.70 W/m2 时,熔盐出口温度可以在 559℃下维持 50 min;12:00定日镜场的余弦效率、阴影与遮挡效率、二次反射阴影效率和大气透射率分别为0.856 8、0.999 7、0.994 1、0.974 6,二次反射镜照度和吸热器照度分别为 11.3 kW/m2 和 400.5 kW/m2,同时电站在50 MW的额定发电功率下维持 16 h.该研究内容对二次反射塔式电站运行和理论研究具有一定参考意义.

The beam-down concentrating solar power plant has the advantages of high concentrating ratio,low installation and maintenance requirements,and low pump consumption.Relying on the 50 MW beam-down tower concentrating solar power station in Yumen Xinneng First Power Co.,Ltd.,the mathematical models of the heliostat field,hyperboloid mirror,receiver,molten salt tank,and power generation cycle are established and verified.The run-test results reveal that,the maximum outlet temperature of the molten salt can be maintained at 559℃for 50 minutes at an average direct normal irradiation of 739.70 W/m2.The cosine efficiency,shading and blocking efficiency,shading efficiency of the hyperboloid mirror,and attenuation efficiency of the heliostat field at 12:00 are 0.856 8,0.999 7,0.994 1,and 0.974 6,respectively.The average hyperboloid mirror flux density and receiver flux density are 11.3 kW/m2 and 400.5 kW/m2,respectively.Meanwhile,the power station is maintained for 16 h at the rated generation power of 50 MW.The research has certain reference significance for the operation of a beam-down concentrating solar power plant.
