摘要
为了满足德国Niederaussem电厂K号机组(1×1000MW)循环冷却水的要求,德国的工程师们建造了目前世界第1的超大型冷却塔。塔的高度200m,底部直径约152m。在工程前期和实施阶段,进行了多方面的研究分析:优化总体尺寸,大量风洞试验,有限元分析和非线性分析,并且采取了多项工程措施,例如:上环梁施加预应力,研制特种混凝土,为了在线监测冷却塔在长期运行中的状况周密制定了监测纲要。有的技术创新值得国内同行参考和借鉴。
To meet circulating cooling water requirements from unit No. K (1×1 000 MW) of Germen Niederaussem Power Plant, German engineers built the world No. 1 super large cooling tower with a height of 200 m, and a base diameter of about 152 m. Researches in many aspects were performed during preliminary and implementation stages of the project, such as overall size optimization, extensive wind tunnel tests, FE and nonlinear analysis. Many engineering measures, for example, pre-stressed upper ring girder, special concrete development, and carefully designed monitoring guild lines for acquiring long term operation data from online monitoring, have also been adopted. Some technology innovations are worthy referencing by domestic colleagues
