摘　　要：从脱硝还原剂氨站的安全性、技术成熟性和应用广泛性、初投资和运行费用等方面对几种SCR脱硝还原剂进行了比较,结果表明:纯氨法的建造、运行成本较低,一般情况下,宜采用纯氨为脱硝剂。The reducing agents on SCR DeNO system are compared. The selection of appropriate reducing agent is analyzed. The safety, maturity, universality, investments and operation expenses of different reducing agents＂ ammonia station are compared. The results show that the investments and operation expenses of the liquid ammonia as reducing agent is lowest. In normal condition ,the liquid ammonia as reducing agent is preferred.
