Abstract
An apparatus and a method for cooling and/or sealing a gas turbine by selectively boosting the pressure of air extracted at a lower extraction stage is provided. The pressure of the extracted air is boosted by an external compressor before it becomes available for cooling and/or sealing the turbine components. A bypass line includes a higher extraction stage providing air for cooling the turbine.
