【摘要】："三北"地区常年风力大,而大风对间接空冷系统的性能会产生影响,尤其是短历时大风会造成凝汽器背压明显增加,进而影响机组运行的安全性和经济性。利用CFD流体计算软件,对各种大风防护措施进行了模拟计算,对比各措施的效果,分析各措施的优缺点,结果表明:主导风向明确的厂址,挡风墙是最佳防大风措施;主导风向不明确的厂址,百叶窗为最佳防风措施。
[Abstract]:In Sanbei area, the wind is strong all year round, and the wind will affect the performance of indirect air-cooling system, especially the short-duration gale will cause the condenser back pressure to increase obviously, which will affect the safety and economy of the unit operation. By using CFD fluid calculation software, various gale protection measures are simulated and calculated, and the advantages and disadvantages of each measure are analyzed. The results show that the windshield wall is the best gale prevention measure where the dominant wind direction is clear; The main wind direction of the site is not clear, blinds for the best wind protection measures.
