Abstract: A blade for a continuous flow machine, wherein the blade is formed along a radial direction and has a blade tip and a blade cross-sectional profile with a pressure side and a suction side. The blade has a blade tip surface which is opposite a housing inner wall during operation. The blade tip surface has an abradable coating, wherein the abradable coating is formed in such a way that a wearing away of the abradable coating takes place during operation, when coming into contact with the housing inner wall, wherein the abradable coating is formed with an abradable coating surface, wherein notches are arranged in the abradable coating surface.

Abstract: A combustion chamber (“steam booster”) system for burning hydrogen with the aim of heating a flow of steam and/or of increasing the steam states of the hydrogen, and a method and a plant. In the combustion chamber system, hydrogen and preferably oxygen can be burned in the presence of water and/or water vapor in a combustion chamber, steam can flow around the combustion chamber on the outside in an intermediate space, in particular can flow over the entire length of the combustion chamber in the intermediate space of a flame tube.

Abstract: An installation with a steam turbine, a steam generator, and also a condenser, the steam generator being connected in terms of flow to an inlet of the steam turbine, and an outlet of the steam turbine being connected to the condenser, with the condenser being connected to the steam generator. A booster is arranged in a steam line that leads into the steam turbine in which an oxyhydrogen reaction takes place, the resulting steam being fed to a steam turbine.

Abstract: A sealing arrangement for a duct, through a stationary housing, of a shaft which rotates about an axis is provided, wherein a sealing liquid is used for sealing instead of sealing steam. The sealing arrangement includes a seal, having a vapor steam extraction system, and a feed line, which is arranged between the inner space and the vapor steam extraction system and is designed for supplying a sealing liquid, wherein a labyrinth seal, a brush seal with metallic bristles, a brush seal with bristles made of natural fibers and/or a brush seal made of synthetic fibers is provided for sealing off with respect to the inner space and the vapor steam extraction system.

Abstract: A rotor for a double-flow turbomachine is provided, wherein the first flow and the second flow have several rows of rotor blades, wherein at least one row of rotor blades is different from the corresponding row of rotor blades of the other flow.

Abstract: A brush seal for a turbo-machine for sealing a gap between a rotating and a stationary component is disclosed. Elastically flexible bristles are arranged in a plurality of rows that are adjacent to each other. A film or a disk is arranged between at least two rows of bristles, the film or the disk extending in the longitudinal direction of said bristles.

Abstract: A sealing ring for turbo engines is provided. The sealing ring includes individual sealing segments, between which springs are mounted. Locking elements are provided on the parting joint of the turbo engine to retain the sealing segments. In order to ensure that the sealing elements can be securely closed on the parting joint, the sealing segments are positively interconnected on the parting joint.

Abstract: The invention relates to a multistage brush seal of a steam turbine that comprises several brushes which in turn comprise several bristles. A plurality of brushes are arranged next to each other and are configured different from each other with regard to the length of the bristles, or to the bristle thicknesses, or to the bristle rigidities, or to the lay angle of the bristles, or to the height of a first guard ring in front of or behind the brush seal in the flow direction, which delimits this brush seal, or to a gap between the bristles and an opposing surface.

Abstract: A rotor blade for a turbomachine, particularly a steam turbine is provided. The rotor blade includes a turbine blade and a blade base, wherein the turbine blade has a suction side and a pressure side, as well as an inflow edge and an outflow edge, wherein an erosion protection shield is disposed at a distance in front of the outflow edge in order to avoid liquid impingement erosion.

Abstract: The invention relates to a multistage brush seal of a steam turbine, the brush seal comprising several brushes which in turn comprise several bristles. Conventional multistage brush seals have a conservative configuration because a precise prediction regarding the pressure difference of a single stage is not possible. The aim of the invention is therefore to provide a brush seal that allows a more precise prediction in respect of the pressure difference in a single stage or brush and thus provides a more precise dimensioning of the brush seal while achieve possible savings. The invention proposes that the adjacently arranged brushes have a varying configuration in respect of different parameters.
