1. Introduction
Now the frequency conversion driving technology had been applied widely to adjust the running load of boiler fan in order to improve the unit’s efficiency for it was beneficial to reducing the energy consumption of the firepower plant [1–5]. With the increase in the fan’s parameters and the application of the frequency changer, the torsional resonance easily occurred for the shaft which connected the boiler fan with the frequency changer when the boiler fan was in the variable speed operation. Once the torsional resonance appeared and was not eliminated timely, the shaft’s failure would not be avoided [6–9]. The induced draft fan of a power plant in 2012 suddenly appeared the abnormal phenomenon when it was running in condition of the variable frequency. The shaft of the induced draft fan was found to fracture after the emergency shutdown and the fracture happened near the site of the shaft’s variable diameter. The shaft’s smallest diameter was 225 mm and the chamfer of the shaft shoulder is less than 2 mm, as shown in Fig. 1. In this paper, the failure investigation had been paid attention to the analysis of failure cases which ranged from material performance, equipment’s design to service condition of equipment, and thus the preventive measures were developed in order to avoid the recurrence of the similar failure.
