摘　　要：通过对朝阳电厂锅炉引风机出力不足原因的分析，提出了增加叶轮直径提高引风机出力的方法，改造后实际运行表明引风机性能完全满足锅炉额定负荷的要求，从根本上解决引风机出力不足的问题。Based upon the cause analysis on the deficiency of boiler induced draft fan output of chaoyang power plant, the method of raising the output was put forard, which increases the diameter of blade wheel. The real operation shows that the chacteristics of the induced draft fan after reforming fully meets the requirement of boiler with rated load; thus it solves the problem of output deficiency radically.
