国产600MW直接空冷机组尖峰喷淋装置对空冷岛运行经济性的分析与应用

本文通过分析尖喷淋峰装置对于空冷环境温度的调节,提高夏季带满负荷小时数,稳定机组在最佳状态。从尖峰喷淋装置的性能控制出发,确定了超临界空冷机组实际运行需对空冷凝汽器管束增加喷淋降温系统,以求达到最热季管束降温、散热的目的,增加发电效率。

This article through the analysis pointed spray device for air cooling temperature peak regulation, improve the summer hours at full capacity, stable unit in the best state. Starting from rush spray device performance control, determine the supercritical air cooling unit operation need to air condensing steam condenser tube bundle increase spray cooling system, in order to achieve the purpose of hottest season bundle cooling, heat dissipation, increase the efficiency.
