摘　　要：我国平板玻璃工业正面临严峻的NOx控制形势,研究并推广玻璃窑炉高效脱硝技术对玻璃工业发展及大气环境保护均具有重要意义。选择性催化还原(SCR)脱硝技术是国内外公认效率最高的脱硝技术,然而该技术在玻璃窑炉中推广应用还面临诸多技术问题。本研究设计并建设了10 000 Nm3/h的平板玻璃工业窑炉中低温SCR脱硝中试装置,分析了玻璃窑炉烟气组分波动规律及其对SCR脱硝系统的潜在影响,考察了烟气温度、喷氨量控制和烟气处理量等工艺参数,开展了为期6 d的连续运行实验。这些在实际烟气中开展的研究为玻璃窑炉SCR脱硝技术研究分享了大量一手数据和经验。In China,the flat glass industry is facing great challenge in NOxcontrol.The research and application of highly efficient deNOxtechnologies for flue gas from flat glass furnaces are benefit to both glass industry development and atmospheric environmental protection.Selective catalytic reduction(SCR) of NOxis considered to be the most efficient deNOxtechnology,but some technical problems prevent SCR technology from glass furnaces.On the basis of the successful design and construction of pilot scale(10 000 m3/h) SCR system at a flat glass furnace,we analyzed the influent fluctuation and the corresponding effects,investigated the critical process parameters including flue gas temperature,ammonia control and flue gas volume,and then carried out a six-day running test.By these work conducted in real flue gas,a number of first-hand data and experience focusing on SCR technology for the deNOxof flat glass furnaces were shared in this paper.
