摘要(Abstract):
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/m~2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/m~2和400.5 kW/m~2,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。
