摘要

结合华电灵武发电有限公司空冷机组的实际情况

对直接空冷系统在严寒环境下出现的冻裂问题进行了分析

提出了防治冻裂的对策。通过改进空冷岛结构

优化运行过程中不同环境条件下的风量调节等措施

可有效克服直接空冷系统运行中出现的冻结问题

从而提高空冷机组安全经济运行水平。

Abstract

Combined with real situation of air cooling units in Huadian Ningxia Lingwu Power Generation Co Ltd

the frost-cracking problem occurred in direct air cooling system under severe cold circumstances has been analysed

and counter measures for preventing frost-cracking being put forward.Through measures

such as retrofitting the structure of air cooling island

and adopting adjustment of the air flow rate under different environmental conditions in operation-optimizing process

the freezing problem occurred in operation of direct air cooling system can be effectively eliminated

thereby

the safe and economic operation level of air cooling units being enhanced.
