摘要
除氧器是热力发电厂保证锅炉给水品质的关键设备，其性能的优劣关系到发电设备的安全运行和使用寿命。对于除氧效果恶化的除氧器应实施改造，以使其恢复性能。为此，针对喷雾填料式除氧器和旋膜式除氧器的三种改造方案，进行了技术经济性分析比较，为电厂除氧器改造提供了最佳的方案选择。
The deaerator is a key equipment to assure the hailer fed water quality in thermal power plant. The deaerators performance influences directly on safe operation and service life of power equipment. The deaerators must be retrofitted, if their deaeration becomes worse. the retrofit variants have an effect on deaeraion results, retrofit cost and recovery time of investment. This paper gives three retrofit variants for spraying and film type deaerator, with their technico- economical comparison, thus provides the way for selection of a optimal retrofit variant.
