摘要
论述了余热锅炉SCR脱硝的工艺流程和特点,具体包括尿素溶液制备储存系统、尿素热解系统、SCR反应器系统,并与燃煤电站锅炉SCR脱硝工艺进行对比,对余热锅炉SCR脱硝进行优化研究,具体对脱硝运行过程中,部分电厂尿素热解炉底部和尾管处有尿素结晶的主要原因进行分析,并对喷氨格栅的设计和运行进行了优化研究。
The technological process and characteristics of SCR denitrification of waste heat boiler are discussed in this paper. The optimization of urea pyrolysis furnace is studied, and the design and operation of ammonia injection grille are optimized.
