Abstract
Official abstract text for this publication.
A gas turbine having a compressor, a turbine unit, at least one combustion chamber and a secondary air system, which secondary air system has at least one cooling line having a compressor-side inlet for removing cooling air from the compressor and a turbine-side outlet for leading the cooling air onward into the turbine unit, wherein the cooling air line at the compressor-side inlet is connected fluidically to a housing opening of the gas turbine which adjoins a cavity in the gas turbine and which, during operation, guides compressor air, and wherein the housing opening is formed as a manhole.
First claim
Opening claim text (preview).
1 . A gas turbine comprising: a compressor, a turbine unit, at least one combustion chamber, and a secondary air system, which secondary air system has at least one cooling air line with a compressor-side inlet for drawing cooling air from the compressor and a turbine-side outlet for conveying the cooling air into the turbine unit, wherein the cooling air line is fluidically connected, at the compressor-side inlet, to a casing opening of the gas turbine which adjoins a cavity of the gas turbine which, in operation, conveys compressor air, wherein the casing opening is designed as a manhole. 2 . The gas turbine as claimed in claim 1 , wherein the cooling air line comprises at least one pipe and an adapter part, wherein the casing-opening-side end of the pipe is connected to the adapter part, which adapter part is connected to the casing opening via a first opening. 3 . The gas turbine as claimed in claim 2 , wherein the adapter part has a second opening opposite the first opening, which second opening is configured as a manhole and can be closed with a removable cover. 4 . The gas turbine as claimed in claim 2 , further comprising: two pipes, in which are arranged valves for setting the throughflow quantity.
