摘　　要：该新型应用在墙式切圆燃烧的锅炉中,能够有效的解决锅炉原有锅炉因为一次风风率过大而导致的煤粉气流扫墙现象,锅炉原有水冷壁超温问题消除;同时,一次风与二次风形成分级燃烧,还在一定程度上降低了锅炉原有NOx的排放。This new type is used in the wall-type tangentially fired boiler, it can effectively solve the original phenomenon that the boiler coal power sweeps the wall due to the excessive primary air ratio, eliminates the original problem of boiler water-cooled wall overtemperature;simultaneously, primary air and secondary air form staged combustion, it also reduces the original boiler NOX emissions to a certain extent.

关 键 词：超超临界锅炉 NOx
