摘要： A method is disclosed for inspecting a weld joining a first rotor disk made of nickel alloy and having an inner surface and an outer surface concentric with the rotor's longitudinal axis to a second rotor disk having an inner surface and an outer surface concentric with the rotor's longitudinal axis. The weld made of nickel alloy fills a radial gap between the rotor disks, and has a dissimilar microstructure to either of the rotor disks. The method includes forming at least one slot in the first rotor disk extending through either the inner surface or the outer surface of the first rotor disk terminating in the first rotor disk; and passing an inspection signal from the first slot to the weld to inspect the weld for defects.

摘要： A steam power plant with retrofit kit has a steam generator (1) with superheater, a steam turbine set including condensation installations (11), connecting pipelines, auxiliary devices and a generator (10). The steam power plant (22) is distinguished by the fact that the retrofit kit includes a retrofit turbine module (25) which is designed for elevated temperature and for unchanged or modified pressure and is connected upstream of the existing steam turbine set or is exchanged for the high-pressure turbine of the latter. Furthermore, a method for retrofitting an existing steam power plant includes the following steps: connecting a retrofit turbine module (25) for high operating temperatures and unchanged or modified operating pressure upstream of the existing turbine set or exchanging the existing high-pressure turbine for the retrofit turbine module (25); providing a steam generator (1) and/or superheater (32) for high live steam temperature. This improves the efficiency and/or the service life of an existing steam power plant. The retention of as many original parts of the steam power plant as possible leads to an inexpensive solution for increasing output. Moreover, the general infrastructure can be maintained to the extent that to do so is economical and environmentally compatible.

摘要： A steam turbine is provided having a relief groove which is arranged in the region of the equalizing piston and extends in the circumferential direction of the rotor. The relief groove, with regard to an inlet passage, is arranged in the axial upstream direction so that it is arranged on the rotor outside a region in which the steam flow enters the bladed flow path via the inlet passage. The relief groove, with regard to the first blade row, is arranged in a region in which the greatest thermal stresses can arise in the rotor. As an option, the relief groove has a cover for reducing vortex flows, and also devices for reducing heating of the groove or devices for active cooling. The steam turbine allows an increased number of risk-free running up and running down operations of the steam turbine with minimum detriment to the turbine performance.

摘要： The invention relates to a generator system for generating an increased braking power, in particular during the startup and/or powering down of a turbine, drivingly connected to a generator, of a turbine system, e.g. a CAES system. The generator system includes the generator, which for generating current is drivingly connected to the turbine, and a transformer, which is connected on the primary side to the generator and on the secondary side to an external current network. A means for frequency adaptation is disposed between the generator and the transformer and is expediently embodied as capable of being put on line. By putting the means for frequency adaptation on line during the startup and/or the powering down of the turbine system, the turbine is acted upon by a greater braking power. In this way, the development of ventilation in the turbine can be largely avoided.

摘要： A steam turbine (10), especially for the high-pressure range or intermediate-pressure range, includes a rotor (11) which is rotatably mounted around an axis and concentrically enclosed at a distance by an inner casing (12), wherein between the rotor (11) and the inner casing (12) a flow passage (13) is formed, which on the inlet side is axially delimited by a balance piston (18) which is arranged on the rotor (11), and into which flow passage rotor blades (15) and stator blades (17), alternating in the direction of flow, radially project, and wherein, at the entry of the flow passage (13), an inlet scroll (14), through which steam is guided from the outside radially inwards and deflected in a deflection region (27) in the axial direction to the inlet of the flow passage (13), is formed on the inner casing (12). A reduction of the thermal loads and stresses is achieved by a stress-relief slot (20) in the deflection region (27) upstream of the first rotor blade row (15) for reducing stresses in the fastening slot (16) of the first rotor blade row (15) in the rotor (11), and by a heat shield (21) arranged in the region of the stress-relief slot (20) for protecting the rotor (11) against high temperatures.
