Abstract: An apparatus and method for orienting a guide vane carrier relative to a turbine casing. The apparatus has a guide device with a first region and a second region, wherein the first region is arranged in a recess of the guide vane carrier and the second region is arranged in a recess of the casing. The second region of the guide device has a guide channel with a first internal thread, wherein a first adjusting element with a first external thread is arranged in the guide channel. The first external thread can be screwed together with the first internal thread. The first adjusting element can be arranged in the guide channel such that, when the guide device is supported against a support surface of the recess, a force flow runs through the first adjusting element from the recess to the guide device.

Abstract: A screw bolt for connecting a lower casing part of a turbine and an upper casing part of a turbine, has a bolt body with a lower end and an upper end, an external thread being arranged on both the lower end and the upper end. A casing for a turbine has a lower casing part, an upper casing part, a screw bolt and two attachment nuts screwed onto ends of the screw bolt, wherein the upper casing part has an upper receiving section and the lower casing part has a lower receiving section of a continuous screw bolt receiving portion for receiving the screw bolt. A turbine has such a casing and a method for assembling such a casing of a turbine.

Abstract: A turbine housing for a turbine is provided. The turbine housing includes a wall cladding on an inner wall of the turbine housing. In a region of joint flanges, the wall cladding is arranged and embodied such that the wall cladding reduces convective heat transfer and thermal radiation in a region of the joint flanges.

Abstract: In order to be able to realize especially high live-steam parameters (i.e. live-steam temperatures and live-steam pressures) in a steam turbine, an admission section of the turbine casing which has a number of throughflow openings and is intended for a valve casing for control valves, has a sealing surface which encloses each of the throughflow openings. For an especially reliable seal, a high surface pressure is achieved in the sealing-surface region owing to the fact that an outer contour of the sealing surface is shaped so as to be constricted in the region between adjacent throughflow openings and that, screws of different dimensions are expediently disposed along the constricted outer contour.
