摘　　要：直接空冷机组的运行状况受周围环境的影响很大,不同的风速、风向不仅会影响到机组运行的经济性,甚至还会造成掉闸停机事故。本文在总结火力发电厂空冷系统特点的基础上,对现场环境及所采集数据进行了系统分析,重点研究了环境作用对直接空冷机组空冷风机吸入风量和入口温度以及空冷机组背压影响,同时分析了环境温度的变化对空冷机组供电煤耗的影响。The operating conditions of direct air- cooled thermal power unit greatly are influenced by environmental, Adverse wind speed, wind direction will not only affect the economics of plant operation, can also cause serious downtime incidents dropped gate. based on the characteristics of thermal power plant air - cooling system, environment wind and the collected data were analyzed, Focuses on the environmental wind on the direct inhalation of the air cooling fan air- cooling unit air volume and inlet temperature. It also analyzed changes in ambient temperature air- cooled unit coal consumption of power.
