摘要
介绍了选择性催化还原法烟气脱氮工艺的基本原理,比较了采用液氨、氨水和尿素3种还原剂时系统的安全性、场地因素、投资费用和运行维护性等,给出了3种还原剂各自适用的范围.液氨、氨水和尿素的安全性都可以达到可控状态,推荐以尿素作为还原剂.
The principle of Selective-Catalytic Reduction （SCR） is described. The system are compared in safety, site, investment, costs of operation and maintenance while taking liquid ammonia, NH4OH, CO（NH2 ）2 as reducing agent respectively. Consequently, the conditions under which each agent required are suggested.
