Definitions

  • the invention relates to a turbomachine with a Inner housing and a rotatably mounted turbine shaft.
  • each turbine or sub-turbine understood by a working medium in the form of steam is flowed through.
  • gas turbines with gas and / or air as the working medium flows through, but completely different temperature and pressure conditions is subject to the steam of a steam turbine.
  • gas turbines has steam turbines z.
  • a steam turbine usually includes one with shovels rotatably mounted turbine shaft, which within an inner housing is arranged. When flowing through the inner housing interior space of the flow space with heated and formed pressurized steam, the turbine shaft on the Shovel rotated by the steam.
  • the blades of the turbine shaft are also called blades designated.
  • On the inner housing are also usually Guide vanes suspended in the interstices of the Grasping blades.
  • the inner housing can also be called Designate housing shell.
  • a vane is usually at a first location along an inside of the steam turbine casing held. She is usually part of it a vane ring, which has a number of vanes includes, along an inner circumference of the inner housing are arranged. In this case, each vane with her Airfoil radially inward.
  • Steam turbines or steam turbine engines can be used in high-pressure, Medium-pressure or low-pressure turbine sections are divided.
  • the inlet temperatures and inlet pressures of high-pressure turbine sections can be 600 ° C or 300 bar.
  • the object of the present invention is to provide a turbomachine in particular steam turbine, with an inner housing and specify a rotatably mounted turbine shaft, the production-oriented can be performed more easily.
  • turbomachine with an inner housing and a rotatably mounted turbine shaft, the inner casing and the turbine shaft are out made of different materials.
  • the invention is based on the finding that the use of same high-chromium materials for both Turbine shaft as well as for the inner housing not necessary is. It was surprisingly found that the Thermal expansion for high steam conditions in the used Masses for the turbine shaft and the inner housing lower are considered a given tolerance limit.
  • the inner housing made of a material with lower heat resistance, as the material from which the turbine shaft is made.
  • the possibility is created to use for the inner housing a material that has a lower heat resistance compared to the material used for the turbine shaft.
  • the material used for the inner case may have higher mechanical strength. Hot strength is understood to mean a permissible stress stress at high temperatures.
  • a chrome steel with 9 to 12 wt.% Chromium has a high Heat resistance, especially when used for turbine shafts is necessary at high steam conditions.
  • a chrome steel with 1 Although up to 2 wt.% Chromium has a lower heat resistance as the chrome steel with 9 to 12 wt.% Chromium, but one higher mechanical strength. Therefore, a chrome steel is with 1 to 2 wt.% Chromium very good in environments with lower suitable for thermal loads. In particular, this is Chrome steel for inner housings in steam turbines with high steam conditions suitable.
  • the use of different materials for the inner casing and for the turbine shaft is particularly suitable in Steam turbines, high-pressure turbine sections, medium-pressure turbine sections, Combined high-pressure and medium-pressure turbine sections or combined medium-pressure and low-pressure sub-turbines.
  • the different materials in pumps, compressors, Gas turbines or compressors are used.
  • the compact steam turbine 1 has an outer casing 2, in which a turbine shaft 3 about an axis of rotation 4 is rotatably mounted.
  • the compact steam turbine 1 has an inner housing 5 with a high pressure part 6 and a Medium-pressure part 7 on. In the high pressure part 6 are different Guide vanes 8 attached.
  • the turbine shaft 3 is by means of bearings 10, 11th rotatably mounted.
  • the inner housing 5 is connected to the outer housing 2 connected.
  • the steam turbine 1 has a high-pressure section 12 and a medium-pressure section 13. In the high pressure section 12 Blades 14 are attached. In the medium pressure section 13 are also blades 15 attached.
  • Der Live steam flows through the individual guide vanes 8 and Blades 14 in the high pressure part 12 and is thereby relaxed and cooled.
  • the thermal energy of the Live steam is converted into rotational energy of the turbine shaft 3.
  • the turbine shaft 3 is thereby in a to the Rotation axis 4 shown direction rotated.
  • the turbine shaft 3 is in a storage area 23 with the Outer housing 5 stored.
  • the blades 14, 15 are not shown in more detail.
  • the live steam first hits the middle region 16 of the turbine shaft 3 and relaxes in the high pressure part 6.
  • the live steam cools down here.
  • the reheated steam flows first at the location of the medium-pressure inflow 18 on the turbine shaft 3 and relaxes and cools in Direction of the medium-pressure part 7 from.
  • the medium pressure part in the 7th then relaxed and cooled steam then flows out
  • the turbine shaft 3 has a heat-resistant material.
  • the heat resistant material is a chrome steel with 9 to 12 wt.% Chromium part.
  • the inner case 5 is made of a different material.
  • the inner housing 5 is made of a material produced with lower heat resistance than the material from which the turbine shaft 3 is made.
  • the inner housing is made in particular of a chromium steel with 1 produced up to 2 wt.% Chromium.
  • Different materials can be used for the turbine shaft 3 and for the inner housing 5 in high-pressure turbine sections, in medium-pressure turbine sections, Combined high-pressure and medium-pressure turbine sections or combined medium-pressure and low-pressure sub-turbines, Pumps, compressors, gas turbines or Compressors are used.
