摘　　要：玻纤窑炉是熔化玻璃液的主要热工设备,在熔化玻璃液的过程中不可避免产生大气污染物NOx,随着玻纤产能的逐年增加,玻纤窑炉污染物的治理技术关注度逐步增加,同时地方政府对企业外排的NOx控制越来越严格,向超低排放控制。本文通过比较SCR(选择性催化技术)和SNCR(选择性非催化技术)两种脱硝技术的异同以及实践,给出了比较适合玻纤窑炉的NOx的处理技术方案,并对实践中遇到的技术要点进行了阐述,经过实践也取得了较理想的脱硝效果。E-glass fiber furnace is the main thermal equipment for glass fiber production line.In the process of melting glass liquid,it is inevitable to produce nitrogen oxide.With the increase of glass fiber production capacity year by year,the technical attention of glass fiber furnace pollutants is gradually increasing.In this paper,by comparing the similarities and differences of SCR(selective catalysis technology)and SNCR(selective non-catalysis technology)two denitrification technologies and practices,a more suitable technical scheme for the treatment of NOx in glass fiber furnace is given,and the technical points encountered in practice are described,and the ideal denitrification effect has been achieved through practice.
