摘　　要：ＡＳＮ－２０７０／９００型动叶可调轴流风机配置在国产３００ＭＷ机组的１０２５ｔ／ｈ锅炉上，近几年来多次发生叶片断裂事故。文章系统地分析了其断裂的原因，得出了结论及具体的处理意见。The 1 025 t/h boilers of homemade 300 MW generating units are equipped with ASN2070/900 type axial flow forced draft fans with adjustable moving blades. In the recent years bladecracking faults occurred repeatedly. The causes for blade cracking are systematically analyzed in this article, and the conclusion and concrete handling proposals are put forward as well.
