| 摘要 |
The invention relates to a method and a device for cooling thermally stressed regions in a turbo machine which has a live-steam feed line ( 9 ), an inflow region ( 17 ), a housing ( 2 ) and an exhaust-steam region ( 7 ), a flow medium flowing through the turbo machine ( 1 ) and leaving in the exhaust-steam region ( 7 ) during operation, part of the flow medium from the live-steam feed line ( 9 ) being passed to the exhaust-steam region ( 7 ) and cooled by means of a heat exchanger ( 8 ) before entry into the turbo machine ( 1 ) and entering the turbo machine ( 1 ) via the inflow region ( 17 ), thermally stressed regions that are located in the inflow region ( 17 ) being cooled by the f low medium that has been cooled in this way.
