摘要： A method is described for improving the sealing between rotor and a plurality of blades. The rotor has a plurality of generally axially extending profiled recesses into which a ring of blades, which have corresponding blade root profiles, are inserted in a form-fitting and/or frictionally locking manner into these recesses in a generally axial insertion direction. Between the recesses the rotor has tangential surface sections or circumferential surface sections which extend in the axial direction and circumferential direction and are generally indirectly covered by lower shrouds of circumferentially adjacently arranged blades in the radial direction. At least one of the tangential surface or circumferential surface sections is provided with a step in the radial direction, and a corresponding recess, which adjoins as flush as possible, is provided in the underside of the shroud of the blade which is arranged above it. Corresponding rotors or blades are also described.

摘要： At least one Helmholtz damper is arranged at a combustion chamber for a gas turbine in order to damp thermoacoustic oscillations; the damping volume of this Helmholtz damper is in communication with the combustion chamber via a connecting passage. Optimum damping is achieved in a simple way by virtue of the Helmholtz damper being designed in such a manner that its damping frequency is adjustable.

摘要： In a burner arrangement for the annular combustion chamber of a gas turbine, a plurality of burners are arranged above one another, in each case in pairs in the radial direction, on concentric rings. In a burner arrangement of this type, the mechanical integrity of the turbine casing is increased and operation of the combustion chamber is optimized by virtue of the two burners in a pair of burners being oriented out of the parallel position, in such a manner that their burner axes converge in the direction of flow.

摘要： The invention relates to a steam turbine, in particular a high-pressure turbine, which is enclosed by an inner casing, split into a top part and a bottom part, and an outer casing. The steam turbine, for the purpose of bleeding, has a bleed slot, which leads form the blade duct of the steam turbine through the inner casing. According to the invention, the inner casing has a shrink ring, which on the one hand holds together the bottom part and the top part of the inner casing and on the other hand forms an annular space above the bleed slot for the purpose of collecting bleed steam and passing it into a pipe connection. The shrink ring has a cavity in its center and flat sides being adapted to the outer surface of the inner casing. The cavity of the shrink ring, together with the outer surface of the inner casing, forms the enclosed, tight annular space. the shrink ring is distinguished by the few components and a short production and assembly time.

摘要： Disclosed is a directional control valve comprising a front-side connector and at least one radial connector, wherein the front faces of a valve body (valve shift or seat body) of the directional control valve are pressurized approximately equally, so that the actuating forces for shifting the valve body are minimal. In accordance with the invention, the pressure for pressurizing a rearward front face of the valve body is tapped at an axial distance to the valve body.

摘要： In a gas turbine group which consists essentially of a compressor (2), a first combustion chamber (3), a first turbine (4), a second combustion chamber (5) and a second turbine (6), the first combustion chamber (3) is configured as an annular combustion chamber. This annular combustion chamber (3) is operated by a number of premixing burners (11) which are distributed at the periphery. The first turbine (4) is designed in such a way that its exhaust gases have a temperature level which is above the self-ignition temperature of the fuel (13) used in the second combustion chamber (5). This second combustion chamber (5) consists of a burnerless, annular combustion space in which a number of vortex-generating elements (14) are integrated. The turbomachines, namely compressor (2), first turbine (4) and second turbine (6) are disposed on a rotor shaft (1), this rotor shaft (1) being supported in two bearings (9, 15).
