Failure analysis of gas turbine generator cooling fan

Fracture BladeVia : Failure analysis of gas turbine generator cooling fan for 14° and 19° — blades angle of attack – Springer.

In gas turbine power plants, a fan is used as a cooling system to dissipate generated heat in coils (copper conductors) and generator electric circuits at the end sides of its rotor. In some cases, fracture of blades causes short circuit between rotor and stator and consequently generator explosion and made lot of financial problems. The fracture of cooling fan blades has been occurred five times at the turbine side of the generator in our case of study, just 100 hr after resuming operation after overhaul.
