百万千瓦级燃煤机组烟气脱白技术研究
|
摘要
我国多数燃煤电厂采用湿法烟气脱硫工艺,尾部饱和湿烟气直接排放,形成可视湿烟羽。目前无泄漏式烟气换热器技术与烟气冷凝再热技术均已成功运用于百万千瓦级燃煤机组,标志着燃煤电厂湿烟羽问题能得到有效解决。以这两种烟气脱白技术在两家电厂投运工程为例,从烟气脱白效果、经济性等多方面进行对比和研究。
Most coal-fired power plants in China adopt the wet flue gas desulphurization process,and the saturated wet flue gas at the tail is directly discharged to form visible wet smoke plume.At present,both leakagefree flue gas heat exchanger technology and flue gas condensation and reheat technology have been successfully applied in a million kilowatts coal burning unit,indicating that the problem of wet smoke plume can be effectively solved in a coal burning power plant.Taking these two kinds of flue gas bleaching technologies in operation projects of two power plants as examples,this paper compares and studies the effect and economy of flue gas bleaching.
