    摘要: A seal for stemming leakage flows between adjacent components (9, 20), especially of a gas turbine, has an elastically deformable, thin-walled sealing element (1) and a thin-walled cover element (13) which is U-shaped in cross section and between its legs (15) and its base (14) partially accommodates the sealing element (1). The legs (15) of the cover element (13) are arranged in the sealing arrangement, which features the seal, between two oppositely disposed walls (28) of the other component (9) in a movable manner relative to these walls (28) which, together with the sealing surface (8) of the other component (9), form a groove (27) which is U-shaped in cross section. Forces, which act laterally upon the seal, are absorbed by the cover element (13) and via the legs (15) are diverted into the other component (9) so that the integrity of the seal is maintained even in the case of lateral forces.

    摘要: A turbomachine (2) has a combustion chamber (1), in particular a gas turbine, with a casing (8) which has a closable maintenance opening at least in the region of the combustion chamber (1), which maintenance opening, in the open state, provides access to an outer carrier (3), an inner segment carrier (5), and a front plate (4), which together define the combustion chamber (1). In order to simplify the maintenance of the turbomachine (2) and thereby reduce any downtimes and maintenance costs, the outer carrier (3), the inner segment carrier (5) and the front plate (4) are designed as annular shell elements (13) having a respective bottom half shell (14) and a respective top half shell (15) which can be connected thereto. In the assembled state, the outer carrier (3), the inner segment carrier (5), and the front plate (4) are connected to one another and/or to the casing (8) via connecting contours (7) which are axially releasable from one another.

    摘要: A combustion chamber includes a mixing zone and a combustion zone within which self-ignition of a fuel and air mixture can occur. Fuel and support air are injected laterally at the sidewall of the mixing zone into hot gases passing through the mixing zone. The operating range of the combustion chamber can be increased while noxious substances are reduced by injecting differently controlled fuel/support air mixture jets into different target spaces within the mixing zone.
