摘　　要：2022年初国家能源局发布的国能发安全〔2022〕21号文件,要求全国燃煤电厂在2024年底前完成尿素制氨替代液氨改造。尿素水解制氨工艺越来越多的被用在了大型燃煤机组上。文章基于此背景,对比各尿素制氨工艺,分析尿素水解工艺存在问题的原因,并给出了有效的措施。At the beginning of 2022,the National Energy Administration issued a document[2022],requiring coal-fired power plants nationwide to complete the transformation of urea ammonia to replace liquid ammonia by the end of 2024.The hydrolysis of ammonia production by urea is more and more used in large coal-fired units.Based on this background,this paper compares the ammonia production process of each urea,analyzes the reasons of the problems of the urea hydrolysis process,and gives effective measures.

关 键 词：尿素热解、尿素水解、尿素催化水解 尿素制氨 火电厂脱硝
