摘要
针对1000MW机组不同的铭牌出力提出了4种不同的进入空冷系统的排汽量方案。介绍了直接空冷系统的工艺流程,并针对4种方案对空冷凝汽器散热面积、风机台数、管道列数、排汽管径以及平台高度等的确定进行了详细的计算和分析,为我国建设1000MW电站的空冷系统提供参考意见。
Four schemes of steam discharge into air cooling system were planned according to the different nameplate output definition for 1 000 MW unit. The process flow of direct air cooling system was described. The heat-transfer area of air cooling condenser （ACC） , the number of fans and duct rows, the diameter of discharge ducts and the height of the ACC platform for each scheme were determined by detailed calculation and analysis. The result can be used as reference for the construction of air cooling system in 1 000 MW unit.
