通常以迎面风速作为唯一的变量对火电厂空冷凝汽器进行优化计算。增加虚拟厂界距离作为第2变量,厂界噪声55dB(A),并将虚拟厂界设为距平台分别为200,250,300,350,和400 m的距离,求得各个距离上的最低年总费用,通过对这些费用的分析,即可得到最佳厂界距离上的ACC最优设计方案。同时对目前常用的2种翅片管的优化结果及规律做了对比,还分析了成本电价、贷款利率、设备价格变化对优化趋势的影响。
Air-cooled condensers in thermal power plants are usually optimized with head-on wind as the only variable. Increase the virtual boundary as the second variable, the boundary noise is 55dB (A), and set the virtual boundary as 200, 250, 300, 350, and 400 m away from the platform respectively, then calculate the minimum annual total cost of each distance, The analysis of these costs, you can get the best ACC on the optimal distance between the plant design. At the same time, the optimization results and rules of the two kinds of finned tubes commonly used at the same time are compared. The influence of the cost of electricity, loan interest rate and equipment price on the optimization trend is also analyzed.
