Embodiment Construction

[0048] exist figure 1 The course of the steam 40 in the first embodiment of the steam turbine 1 according to the invention is schematically shown in . The live steam 42 flows from outside the turbine housing 2 through the live steam line 41 into the interior of the first inner housing 11 . The first inner casing 11 is arranged in the first turbine part 10, which is preferably a high-pressure part. The first inner housing 11 has a first sealing area 12 and a first vane area 13 . The first sealing region 12 extends perpendicular to the turbine axis 4 . In this case, the first sealing region divides the first turbine part 10 into a front part 14 and a rear part 15 . The first blade region 13 extends away from the first sealing region 12 parallel to the turbine axis 4 and opposite to the main expansion direction 30 of the steam 40 through the steam turbine 1 . A first guide vane set 16 is arranged on the side of the first blade region 13 facing the turbine shaft 5 . Correspon...

Abstract

The invention relates to a steam turbine (1) comprising a single-shell turbine casing (2) and specific inner casings (11, 21) arranged inside the turbine casing (2).

Description

technical field [0001] The present invention relates to a steam turbine. Background technique [0002] In steam power plants, steam is used as the working medium for the operation of steam turbines. Water vapor under pressure is generated in the steam boiler and flows via lines into the steam turbine. The previously absorbed energy of the working medium in the steam turbine is converted into kinetic energy. Using the kinetic energy, for example, an electrical generator is operated, which converts the generated mechanical power into electrical power. The expanded and cooled steam then flows into the condenser, where it is condensed by heat transfer in a heat exchanger and is pumped back as liquid water to the steam boiler for heating, evaporation and subsequent superheating In order to achieve a higher and highest efficiency in the steam power process, the steam power process is developed towards higher and higher fresh steam parameters. Due to this high live steam param...
