Abstract
A gas turbine unit having a compressor section, a combustion chamber section containing at least one combustion chamber, and a turbine section, wherein, starting from a compressor inlet, a flow path extends. The gas turbine unit is equipped with at least one first and one second cooling air path. The first cooling air path draws off compressed air from the flow path upstream of the at least one combustion chamber. The first cooling air path has a higher pressure level than the second cooling air path and feeds the cooling air. The second cooling air path has a draw-off point in the compressor section, and extends from the compressor section to the turbine section, bypassing the at least one combustion chamber. After components have been cooled, the first cooling air path feeds the cooling air into the second cooling air path at an infeed point as additional cooling air.
