摘要
尿素作为选择性催化还原(SCR)烟气脱硝还原剂得到越来越广泛的应用,但一直存在尿素热解能耗高的问题。利用脱硝与锅炉结合的优势,提出一种利用锅炉高温烟气加热冷一次风,作为尿素热解热源的技术路线,可大大降低尿素热解工艺的能耗,真正实现节能、环保、安全的目标。
Urea has been widely used as a kind of reducer for SCR flue gas de-NOx technology. To pyrolyze urea however requires extra energy consumption. In this paper, a new technology is provided based on combination of de-NOx system with the boiler, where the high temperature boiler flue gas is used to heat the cold primary air as heating resource for urea pyrogenation. Application of this technology demonstrates that energy consumption for urea pyrogenation has been reduced significantly, in favor of energy saving, environmental protection and safer operation of plants.
