The system also includes a rotor disk heating system configured to resistively heat at least a portion of the at least one rotor disk via an electrical current or voltage applied to the portion of the at least one rotor disk.
Claims20
A system, comprising:
- a turbomachine, comprising:
- at least one rotor disk;
- and
- a rotor disk heating system configured to resistively heat at least a portion of the at least one rotor disk via an electrical current or voltage applied to the portion of the at least one rotor disk.
1 more element
A system, comprising:
- a rotary machine, comprising:
- at least one rotor disk, wherein the at least one rotor disk comprises an annular surface having an inner perimeter and an outer perimeter, and grooves within the annular surface;
- and
- a rotor disk heating system comprising a resistive network disposed within the grooves below the annular surface, wherein portions of the resistive network comprise a multilayered heating material, and the resistive network is configured to resistively heat at least a portion of the at least one rotor disk via an electrical current or voltage.
