【摘要】："三北"地區(qū)常年風(fēng)力大,而大風(fēng)對間接空冷系統(tǒng)的性能會產(chǎn)生影響,尤其是短歷時大風(fēng)會造成凝汽器背壓明顯增加,進(jìn)而影響機(jī)組運(yùn)行的安全性和經(jīng)濟(jì)性。利用CFD流體計算軟件,對各種大風(fēng)防護(hù)措施進(jìn)行了模擬計算,對比各措施的效果,分析各措施的優(yōu)缺點(diǎn),結(jié)果表明:主導(dǎo)風(fēng)向明確的廠址,擋風(fēng)墻是最佳防大風(fēng)措施;主導(dǎo)風(fēng)向不明確的廠址,百葉窗為最佳防風(fēng)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.
