600MW机组间接空冷系统的防冻与优化

Freeze protection and optimization for indirect air cooling system of 600MW unit

间接空冷机组因散热器受冻造成的设备损坏和停机事故会给发电企业带来严重的经济损失,从3个方面对间接空冷系统的防冻进行了研究和优化,提出了运行方式调整措施,增加了自动化调节和控制手段,保证了空冷机组散热器的安全。

In the indirect air cooling unit,the freeze injury of the radiator can cause the equipment damage and shut-down accident,which may lead serious economic loss for power generation enterprise.Starting from three aspects,the freeze protection of the indirect air cooling system was researched and optimized.The corrective measures of operation mode were put forward;some automatic adjustment and control measures were added,which can ensure the safety of radiator of air cooling unit.
