Abstract
Method and system are provided for controlling a thermal differential within a turbine rotor for use with a turbine system. A thermal barrier coating is applied to a surface of the turbine rotor. The surface is proximate to a wheel rim of the turbine rotor.
Claims20
A method for controlling a thermal differential within a compressor of a gas turbine system, said method comprising:
- selecting one or more surfaces of a plurality of rotors of the compressor, wherein at least one of the surfaces selected is proximate to a wheel rim of a rotor of the plurality of rotors and at least one of within a loading location defined within the rotor and radially inward from the wheel rim;
- and
- applying a thermal barrier coating to the one or more surfaces of the plurality of rotors to facilitate reducing a transient heat transfer rate during startup.
A plurality of rotors for use within a compressor of a gas turbine system, or each rotor of said plurality of rotors comprising:
- one or more surfaces proximate to a wheel rim of said compressor rotor, wherein said surface is at least one of within a loading location defined within the compressor rotor and radially inward from the wheel rim;
- and
- a thermal barrier coating applied to said one or more surfaces to facilitate reducing a transient heat transfer rate during startup.
A gas turbine system comprising a compressor, said compressor comprising:
- a plurality of rotors, each rotor comprising one or more surfaces, wherein at least one of the surfaces is proximate to a wheel rim of said rotor and is at least one of within a loading location defined within the rotor and radially inward from the wheel rim;
- and
- a thermal barrier coating applied to the one or more surfaces of the plurality of rotors to facilitate reducing a transient heat transfer rate during startup.
