摘　　要：常规的解决NOX 降解的办法 ,有其实现的局限性。发挥再燃与烟气循环的协同作用 ,可在克服这些局限性的同时 ,增强其可实现性 ;烟气再循环的应用 ,在降解NOX 的同时 ,由于其改变了炉膛的局部环境 ,强化了再燃技术降解NOX 的作用。再燃技术和烟气再循环技术的协同 ,形成炉内NOX 的二级降解 ;再燃与烟气循环协同系统的关键 ,在于再燃燃料的种类、喷入量与烟气再循环率大小的确立。It's very limited to use the NO X reduction technolo gy individually. The way of reburning cooperated with recirculation, can enhance t he process of NO X reduction, and it is a more practical way. The application o f recirculation, can change the furnace condition while reduce the NO X formati on; and under the changed condition, reburning can be more efficiency. Reburning cooperated with recirculation, form the two-step way to reducte the NO X. Th e most important thing for this application is the kind of the reburning fuel, the quantity of the reburning fuel and the recirculation rate.
