A gas collection pipe () carrying hot gas establishes the connection between the combustion chambers () of a gas turbine plant and the flow channel () of the gas turbine. The gas collection pipe () has two inlet pipe connections (), which open via an elbow () axially into a gas ring channel (), which is joined to the flow channel (). Cooling air is guided on the outside along the elbow (). A plurality of ribs () are arranged at spaced locations from one another on the outside on the gas collection pipe () in the area of the elbow () on the side facing away from the flow channel ().

Gas collection pipe carrying hot gas

A device for sealing between the guide vanes ( ) and the rotor ( ) of turbomachines, especially gas turbines has inner rings ( ) suspended on the vane footing ( ) of the guide vanes ( ) in a thermally elastic manner with soldered honeycomb seal ( ) and labyrinth tips ( ) arranged on the rotor ( ). First flow channels, which are connected to the cavities ( ) of the cooled guide vanes ( ), through which said cavities cooling air flows, are led through the vane footings ( ). The first flow channels are connected to at least one of second flow channels led through the inner ring ( ) to the vicinity of the honeycomb seal ( ). The second flow channels open into at least one of third flow channels that are open at the rear edge of the inner ring ( ) or are led to an annular groove ( ) open toward the honeycomb seal ( ) on the underside of the inner ring ( ).

Device for sealing turbomachines

A symmetrical component of a turbine unit, whose wall is exposed to a hot medium on one side and is subject to nonuniform thermal stress over the circumference, is cooled by a flow of cooling air being guided along the other side of the component. A ring ( ) is provided with slots ( ) or other openings for the passage of the cooling air. The ring ( ) protrudes into the flow of the cooling air. The overall cross section of the slots ( ) that are arranged in the sections of the ring ( ) that are adjacent to the areas of the component that are subject to the higher stress is larger than the overall cross section of the slots ( ) that are arranged in the sections of the ring ( ) that are adjacent to the areas of the component that are subject to a lower stress.
