摘　　要：除氧器是火力发电厂给水回热系统中的一个混合式加热器,它的作用是除去锅炉给水中的氧气和其它不凝结气体,以保证锅炉给水的品质,除氧器的安全运行是发电厂安全运行的有效保证。本文对火力发电厂一台20万千瓦机组在正常运行时除氧器突然发生爆炸事故进行分析,找出事故原因提出预防事故的措施。Feedwater deaerator is a hybrid heater in the regenerative system of coal-fired power plants,thepurpose of which is to remove the oxygen and other not condensate gas in the boiler feed water, to ensure the qualityof boiler feed water.The security of the deaerator operation is an effective guarantee for the safe operation of the powerplant. This article introduces a deaerator suddenly explode accident in a 200000 unit of a thermal power plant duringnormal operation. According to analysis, the cause of the accident is found and preventive measures are put forward inthis article.
