Systems and methods for providing compressor extraction cooling

摘要

Embodiments of methods and apparatus for providing compressor extraction cooling are provided. According to one example embodiment, a system (120) for cooling compressor extraction air (114) in a gas turbine (100) comprising a compressor (102) and a turbine (104) section can be provided. The system (120) can include one or more storage devices (124) operable to store a cooling medium (122), and one or more distribution devices (126) operable to receive the cooling medium (122) from the one or more storage devices (124). The one or more distribution devices (126) can also be operable to introduce at least a portion of the cooling medium (122) prior to or during introduction of the cooling medium (122) to the compressor extraction air (114), wherein the compressor extraction air (114) is cooled by the cooling medium (122) prior to introduction to the turbine (104) section.
