摘要
冷却塔的运行性能直接影响电厂的经济性和安全性。由于冷却塔运行的复杂性和影响因素的多样性,冷却塔性能的分析和评价十分复杂。通过对评价方法和指标的分析,基于冷却塔现场运行数据,得到了能够正确、全面反映冷却塔性能的评价指标的动态变化,考察了冷却塔的一般性能规律,为合理制定机组负荷、规划冷端性能奠定了基础。基于现场运行数据动态分析了环境侧风的影响。
The performance of cooling tower has a direct impact on the economical and safety running of power plant .As the complexity of operation and diversity of factors, analysis and evaluation of cooling tower performance are difficult and complex. Methods and index were analyzed, and based on operational data of cooling tower, through dynamic analysis of indexes, correct and comprehensive reflections of cooling tower performance were got. The general characteristics of cooling tower were also inspected; they provide basic information for the reasonable formulation of unit load and good plan of cold end performance. The influence of crosswind was investigated through dynamic analysis.
