摘　　要：本文以６００ＭＷ超临界压力直流锅炉为例，讨论了大型燃煤锅炉一、二次风采用同心反切布置的问题，提出了改进二次风喷嘴的方案。最后指出，一、二次风同心反切布置是改善炉内结渣的有效措施。This paper discusses problems of the concentric firing system-II,which is used on large-capeity bollers in fossil-firedpower plants,and presents a plan of mondification to the second air nozzles.It is pointed out that the concentric firing system-II is an very effective measure tO prevent ash slagging on water walls of boiler.
