浅谈风速对空冷机组的影响

The impact of wind speed on air-cooling system of generating unit in power plant

空气冷却技术不仅可以应用于缺水干旱地区和严寒地区的北方,也可以应用于水源充沛的地区。机组在运行中,环境风场的作用有时会使直接空冷系统的换热效率降低,导致汽轮机背压提高,增加了汽轮机的汽耗率。本文对此问题进行了讨论,并提出相应措施减少其影响。

The air cooling system is not only used in dry areas where there is less water and in cold north but also in regions where there is plenty of water. The impact of environmental wind field will decrease the heat exchange rate of air cooling system, increase the back pressure of turbine and the ratio of steam consumption. The paper discusses the problem, puts forward the measures to reduce its impact.
