烟气脱硝技术研究进展和应用展望

Research Progress on Flue Gas Denitration Technology and Its Application Prospect

介绍了烟气中NOx产生的机理和特点,比较全面地综述了国内外常见的烟气控制NOx浓度和脱硝技术特点和技术进展,分析了各种脱硝技术的优缺点和应用现状。提出了我国应根据不同烟气来源与烟气条件,选择合适的脱硝技术,以达到满足烟气脱硝率和降低脱硝成本的目的,为不同烟气选择脱硝技术提供了参考。

The production mechanism and characteristics of NOx from flue gas were described.The technical progress on controlling NOx concentration and denitration technology home and abroad was reviewed.The advantages and disadvantages of various denitration technologies and their application status were analyzed.China should select the appropriate denitration technology based on the different flue gas sources and the flue gas conditions to meet the flue gas denitration rate and reduce the cost of denitration.The way to select denitration technology for different flue gases was introduced.
