Abstract:
1. A gas turbine plant, comprising: a compressor configured to suck in intake air on an inlet side of the compressor, compress the air to form compressed air and discharge the compressed air on a discharge side of the compressor; a combustion chamber configured to combust the compressed air to form a hot gas; at least one turbine configured to expand the hot gas to perform work; first cooling lines configured to cool thermally loaded components of at least one of the combustion chamber and the turbine by recirculating cooling air to the thermally loaded components, the first cooling lines being connected from an exit of the compressor to the thermally loaded components; second cooling lines connected from the thermally loaded components back to the compressor; at least one of a first cooler arranged in the first cooling lines and a second cooler arranged in the second cooling lines; and an injection arrangement configured to introduce water into the recirculated cooling air, wherein the compressor comprises at least one stator blade which has at least one passage for the recirculation of cooling air, which leads through a blade airfoil and comprises at least one opening into a flow passage of the compressor, and wherein the at least one stator blade comprises at least one second water feed line which leads through the blade airfoil and in the blade opens into at least one discharge passage for the recirculation of cooling air.
