摘要: 间接空冷机组在极端气候环境下运行危险点众多,若控制不好,易造成间接空冷散热器管束冻结、凝汽器真空波动大等影响机组安全运行问题,为使该问题得到解决,通过对2台新建机组在高寒、炎热、大风环境下运行实践,对极端天气影响机组安全运行的原因、机理进行深入的分析和研究,制定出一套较为成熟的控制措施,并有效地消除了机组运行中产生的诸多危险因素,对间接空冷机组在极端气候环境下的安全、可靠运行提供了更全面的保障措施。

Abstract: There are risks for indirect air-cooling generators running under extreme climate conditions. Without proper control, they would cause operation safety problems, such ase radiator tube bundle freezing and great fluctuation in condenser vacuum. Based on the practical operation of two newly built units operating in extremely cold, hot and windy weather, this paper analyzes and studies the factors and mechanism that affect the unit secure operation in climate extremes. and a set of preventive measures are proposed to eliminate the risks. These measures can safeguard the indirect air-cooling units operating safely and reliably under extreme weather.

Key words: power plant, indirect air-cooling unit, absolute climate, control measure
