摘要: 針對浙江華能玉環電廠脫硝工程,應用有限元分析方法對煙道結構進行小變形彈性和大變形彈性模擬,對鋼結構煙道在實際荷載作用下的力學性能進行了分析,探討了煙道長度變化對煙道結構應力和變形的影響.考慮大變形影響時,煙道的應力分布均勻,其應力值較不考慮大變形的應力值小5%~50%,煙道長度的變化對應力值的影響不超過20%.結合現場監測驗證了數值模擬的可靠性.

Abstract: A denitration project in Zhejiang Huaneng Yuhuan Power Plant in China was taken as the research object, and the finite element method was used to simulate elastic properties in small deformation and large deformation. The mechanical properties of the flue in practical load were studied, and the influence of the flue length on the stress and deformation were discussed. It is found that because of considering large deformation effect, the equivalent stress of the flue is well-distributed, and its values decrease by 5% to 50% The influence of the change in flue length on the stress is less than 20%. At last, monitoring was used to show the reliability of numerical simulation.
