Abstract (en)

The device for the cooling of a gas turbine casing (2) and/or a combustion chamber has a cooling gas supply unit (7), a cooling gas path (10) directed through the casing in its circumferential direction, and a switching unit (13) switchable between a first position, in which it connects the outlet (8) of the cooling gas supply unit to a first casing connection (11) and connects the inlet (9) of the cooling gas supply unit to a second casing connection (12), and a second position in which it connects the outlet of the cooling gas supply unit to the second casing connection and connects the inlet of the cooling gas supply unit to the first casing connection. An independent claim is included for a method for the cooling of the casing of a gas turbine and/or of a combustion chamber of a gas turbine.
