Definitions

  • rotors undergo large stress that may cause crack initiation; for example, areas of the rotor prone to crack initiation are the teeth defining slots where blades (e.g. turbine blades or compressor blades) or generator windings are connected.
  • blades e.g. turbine blades or compressor blades
  • generator windings are connected.
  • the cracks as a rule are monitored and in case their size becomes too large, the rotors are replaced.
  • the impossibility to carry out heat treatments on the rotors after manufacturing prevents the rotors from being repaired when cracks are identified.
  • Figure 2 shows a portion of a cross section through line II-II of figure 1 and shows the profile of the rotor or rotor disc with teeth 3 defining slots 4 inbetween; the slots 4 house and hold blades, e.g. of a turbine or compressor. In different embodiments the slots may also hold the winding of a turbogenerator or a hydro generator.
  • Figure 2 specifically shows the teeth 3 and slots 4 of a gas turbine where turbine rotor blades are connected via their root.
  • the parts 18 have at least a first hole that houses the heater 15.
  • the heater may be interchangeable, such that a specific heater, able to supply the required heat flux, can be provided according to the heat treatment to be carried out.
  • control unit 17 can drive the heaters 15 based on the measurements of the temperature sensors 16 in order to cause a predefined temperature profile over time through the tooth 3.
