    摘要: A fuel lance for spraying liquid and/or gaseous fuels into a combustion chamber, which fuel lance is provided with first means for the radial spraying of the liquid fuel from the liquid-fuel passage into the combustion chamber. The first means comprise a first guide tube, which, in the radial direction starting from the liquid-fuel passage, runs outward through a gas passage and an air passage. In addition, second means are provided, which comprise a second guide tube, which, in the radial direction starting from the gas passage, runs outward through the air passage and concentrically surrounds the first guide tube at a distance. Both guide tubes open in the region of a shell opening in the lance shell in such a way that the liquid-fuel jet discharging from the first guide tube discharges as a plain jet into the combustion chamber, and the fuel jets discharging from the guide tubes are surrounded in a sheath-like manner by the air flowing out of the air passage through the shell opening.

    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.
