Abstract: A method for checking a steam turbine, wherein a first operating variable and a second operating variable are determined, wherein a correlation between the first and second operating variable prevails, and a confidence band having an upper maximum value and a lower minimum value is created, wherein a notification is generated as long as the second operating variable is outside the confidence band during operation.

Abstract: A method is provided for carrying out a sound test for detecting and/or analyzing material faults and/or mounting faults of at least one component, in which the component is excited, by striking, to experience vibrations which generate soundwaves, after which the generated soundwaves are detected and conclusions are drawn about material faults and/or mounting faults on the basis of the detected soundwaves, wherein the striking of the component and the detection of the vibrations are carried out using an endoscope device. In addition, embodiments of the present invention relates to an endoscope device which is configured to carry out the method.

Abstract: A cooling option for a steam turbine is provided, wherein the steam turbine includes a high-pressure zone and a medium-pressure zone, wherein the saturated steam streaming out of the high-pressure zone is discharged via a saturated steam conduit to a first pressure chamber in a second flow channel of the medium-pressure zone and thus the possibility of the saturated steam causing damage by corrosion and erosion in the high-pressure zone is prevented.

Abstract: A steam turbine having an exhaust-steam casing for directing an exhaust-steam mass flow, a shaft bearing for mounting a turbine shaft, and at least two bearing struts, by means of which the shaft bearing is fastened to the exhaust-steam casing, is characterized according to the invention in that each of the at least two bearing struts has a cooling cavity arranged in the respective bearing strut for directing a coolant, and the cooling cavities of the at least two bearing struts are connected in a fluidically conductive manner via a closed-off connecting cavity in the region of the shaft bearing.

Abstract: A steam turbine has a two-shell housing, including an outer casing and an inner casing arranged therein, as well as a pipe that extends through the outer casing for supplying and/or removing steam to or from the inner casing, the pipe being provided with a pair of apertures arranged opposite each other on the inner casing. According to the invention, a first steam supply or discharge pipe can be connected to a first aperture, and the second aperture is closed by a cover.
