| Abstract: | 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. |
