350MW机组间接空冷系统冬季防冻控制及系统优化

Winter Antifreeze Control and Optimization of the Indirect Air Cooling System of 350 MW Unit

空冷机组因散热器冻结造成的设备损坏和停机事故每年给发电企业带来严重的经济损失,因而空冷机组散热器的冻结问题已成为影响空冷机组安全运行最重要的问题之一。对350 MW机组间接空冷系统进行了介绍,并对表面式凝汽器间接空冷系统的冬季运行防冻控制措施及系统优化进行了论述。

Damages and shutdowns of air cooled generating units caused by freezing ofthe heat radiators brought heavy economic losses to power plants every year, so freezing ofthe heat radiator has become one of the most important problems affecting the safe operationof air cooled units. The indirect air cooling system of 350MW unit is introduced and winterantifreeze measures and optimization for the surface-type compensator indirect air cooling sys-tem are discussed.
