600MW燃煤机组大气污染物超低排放技术应用
摘要
对国内火电厂大气污染物超低排放的关键技术进行了总结
结合国内某电厂600MW机组大气污染物超低排放改造示范工程
重点介绍了影响大气污染物超低排放效果的关键因素
分别给出了NO_x、SO_2及烟尘控制技术方案
强调改造时需根据电厂的客观条件以及现有环保设备的评估结果
合理选择大气污染物超低排放改造技术方案
并应进行系统整体优化设计
协同脱除优化运行
以降低投资、运行及维护成本。
Abstract
The domestic key technical routes to realize ultra-low emissions of flue gas pollutants in coal-fired power plant are summarized.Combining with the ultra-low emission demonstration project of a domestic600 MW unit
this paper focuses on the key factors influencing the ultra-low emissions
it puts forward the control technology scheme for NO_x
SO_2 and dust
and emphasizes that
during the ultra-low emission system optimization
the ultra low emission transformation scheme should be reasonably selected according to the objective condition and environmental protection and evaluation results of the existing equipments in the power plant
and the overall system design and collaborative removal of various emissions should be carried out to reduce the costs of investment
