Abstract
Embodiments of methods and apparatus for providing compressor extraction cooling are provided. According to one example embodiment, a method for providing compressor extraction cooling in a gas turbine comprising a compressor and a turbine section can be provided. The method can include providing a cooling medium. The method can include extracting air from a compressor associated with a gas turbine. The method can also include introducing the cooling medium to the compressor extraction air, wherein the compressor extraction air is cooled by the cooling medium prior to or during introduction to the turbine section.

A method for providing compressor extraction cooling in a gas turbine comprising a compressor and a turbine section, the method comprising:
- providing a cooling medium;
- extracting air from a compressor associated with a gas turbine;
- and
- introducing the cooling medium to the compressor extraction air, wherein the compressor extraction air is cooled by the cooling medium prior to or during introduction to the turbine section.
A system for cooling compressor extraction air in a gas turbine comprising a compressor and a turbine section, the system comprising:
- one or more storage devices operable to store a cooling medium;
- one or more distribution devices operable to:
- receive the cooling medium from the one or more storage devices;
- and
- introduce at least a portion of the cooling medium prior to or during introduction of the cooling medium to the compressor extraction air, wherein the compressor extraction air is cooled by the cooling medium prior to introduction to the turbine section.
A gas turbine comprising:
- a turbine section;
- a compressor, wherein air is extracted from at least one portion of the compressor for introduction into the turbine section;
- one or more storage devices operable to store a cooling medium;
- and
- one or more distribution devices operable to:
- receive the cooling medium from the one or more storage devices;
- and
- introduce at least a portion of a cooling medium prior to or during introduction of the cooling medium to the air extracted from the at least one portion of the compressor, wherein the air is cooled by the cooling medium prior to introduction to the turbine section.
