Definitions

  • the present invention relates to an outflow housing for a turbine section of a steam turbine with reheating.
  • the present invention also relates to a steam turbine with an outlet housing according to the invention.
  • Steam turbines are flow machines that are designed to convert the enthalpy of steam into kinetic energy.
  • Conventional steam turbines have a turbine housing which surrounds a flow space for the steam to flow through.
  • a rotationally mounted turbine shaft with a large number of rotor blades is arranged in the flow space, and these are held on the turbine shaft in the form of rotor blade rings arranged one behind the other.
  • steam turbines In order to optimize the flow of steam onto the rotor blades, steam turbines have guide vane rings, each of which is connected upstream of a rotor blade ring and is held on the turbine housing.
  • a group of a guide vane ring with an associated rotor blade ring is also referred to as a turbine stage.
  • the steam When flowing through the steam turbine, the steam gives off part of its internal energy, which is converted into rotational energy of the turbine shaft via the rotor blades.
  • the steam is relaxed so that the pressure and temperature of the steam as it flows through the steam turbine are reduced after each turbine stage.
  • the turbine housing is thus exposed to a temperature gradient between a steam inlet and a steam outlet. This leads to a very high load on the turbine housing, particularly in the case of compact steam turbines.
  • steam turbines have a plurality of turbine sections, such as, for example, a high-pressure section, a medium-pressure section and / or low-pressure section.
  • Steam turbines have a heating device for intermediate superheating of the steam, so that, for example, steam leaving the high-pressure section can be heated by the heating device before it is fed to the subsequent turbine sections. It can be provided that such a heating device is arranged between two turbine sections.
  • a heating device is arranged between two turbine sections.
  • strong temperature fluctuations occur along a longitudinal axis of the steam turbine.
  • the temperature in the high-pressure section falls gradually, then increases suddenly in the transition area due to the reheating.
  • a region of the turbine housing which is arranged adjacent to an outflow of the high-pressure section and an inflow to the following medium-pressure section or low-pressure section is exposed to particularly large temperature differences, particularly in the case of compactly constructed steam turbines.
  • turbine housings have a plurality of housing parts which are connected to one another to form the turbine housing with the formation of parting lines.
  • Turbine housings often have a lower housing part and an upper housing part.
  • the turbine housing can also have a plurality of housing segments along the longitudinal axis of the turbine, so that the high-pressure section and the medium-pressure section are arranged, for example, in different housing segments.
  • the connection is often made by screwing flanges of the housing parts or housing segments.
  • steam turbines have outflow housings which are arranged inside the turbine housing coaxially to the longitudinal axis of the turbine.
  • a particularly strong temperature gradient occurs in the area of an outlet opening of the discharge housing on the turbine housing, since the steam leaving the discharge housing flows directly onto the turbine housing in this area. If the temperature gradient is too high, the turbine housing can be damaged, especially in this critical area. For this reason, the maximum power of such steam turbines to avoid such high temperature gradients is very limited.
  • the outflow housing is preferably designed as a guide vane carrier.
  • the outflow housing has an outflow housing wall through which a central drum space is formed around the housing longitudinal axis.
  • the central drum space can also be referred to as flow space and is designed to pass through a steam mass flow for driving a turbine shaft of a steam turbine.
  • the drum space extends up to the sealing device and is delimited by this in the direction of the longitudinal axis of the housing.
  • the outlet housing wall is preferably impermeable to steam, so that the steam in the area of the outlet housing is prevented from flowing onto a turbine housing.
  • the outflow housing is preferably designed in several parts, in particular with an upper part and a lower part, and is preferably secured via a flange by fastening means, e.g. Screws held together.
  • a sealing device is arranged at a rear end of the discharge housing in the flow direction in such a way that that an outflow of the steam from the discharge housing is prevented by the sealing device.
  • the sealing device preferably has an outflow housing wall seal for sealing against the outflow housing wall and preferably a turbine shaft seal for sealing against a turbine shaft.
  • the outflow housing wall seal and turbine shaft seal are preferably designed as one assembly or one component.
  • the sealing device is preferably designed essentially according to a sealing shell or at least according to a sealing element of a sealing shell.
  • the sealing element is preferably designed as a lamellar seal and / or sealing lips and / or labyrinth seal. The sealing device can thus prevent an uncontrolled outflow of steam from the outflow housing into a subsequent turbine section.
  • the outflow housing is designed in such a way that the steam, after flowing through the outflow housing, can be guided out of the outflow housing in a targeted manner and supplied to reheating without the steam hitting the turbine housing.
  • appropriately designed lines and / or channels are preferably provided on the outflow housing.
  • An outflow housing according to the invention has the advantage that by means of the outflow housing a steam mass flow conducted through a steam turbine is kept away from the turbine housing in the area of the outflow housing and in the flow direction immediately after the outflow housing. A temperature gradient of the steam mass flow, which arises due to the relaxation when flowing through the turbine, is therefore not transmitted directly to the turbine housing, at least in places. An excessive thermal load on the turbine housing due to an excessively high temperature gradient can thus be prevented.
  • An outflow housing according to the invention can be manufactured inexpensively and makes a subsequent sealing shell to prevent the steam mass flow from penetrating into a subsequent turbine section is superfluous. In this way, part costs and assembly costs can be reduced. Furthermore, the overall length of a steam turbine can be reduced by the compact construction of the outflow housing, in particular since the following sealing shell is no longer required.
  • the outflow housing wall has a receiving device for receiving the sealing device.
  • the receiving device is preferably designed according to a corresponding receiving device of a sealing shell for a steam turbine.
  • the receiving device is preferably designed to hold the sealing device releasably relative to the discharge housing.
  • the receiving device preferably has at least one groove running around the circumference. Fixing means are preferably provided for fixing the sealing device in the receiving device.
  • the outflow housing wall also preferably has at least one outflow channel which at least partially surrounds the housing longitudinal axis.
  • At least one outflow nozzle is arranged on the outflow channel in a fluid-communicating manner, which extends transversely to the housing longitudinal axis, preferably by 90 ° and / or tangentially to the outflow channel, and is designed for the passage of steam.
  • Steam flowing through the drum space of the outflow housing flows into the outflow channel and via the outflow channel into an outflow connector in order to leave the outflow housing via the outflow connector.
  • the discharge nozzle can be coupled to a line which is designed to carry the steam. For example, the steam can thus be fed to a reheating device of the steam turbine. This has the advantage that simple means can be used to prevent steam leaving the discharge housing from flowing against the turbine housing.
  • the sealing device is preferably arranged on a side of the at least one outflow channel facing the housing longitudinal axis, adjacent to the outflow channel, on the outflow housing wall.
  • the sealing device is preferably surrounded or at least partially surrounded by the outflow channel.
  • connection interface is formed on an outside of the outflow housing wall facing away from the drum space.
  • the connection point is therefore preferably arranged in a region of the outflow housing which delimits the drum space in the radial direction.
  • the outflow housing can be coupled to or fixed to the turbine housing via the connection interface.
  • the connection interface is designed, for example, as a circumferential flange or web, which can preferably be fixed to the turbine housing in a form-fitting manner.
  • connection interface for connecting the outflow housing to the turbine housing of the steam turbine is formed on the outflow housing of the sealing device adjacent in the radial direction.
  • a connection interface is preferably already formed on the outside of the outlet housing wall facing away from the drum space, so that a further connection interface on the sealing device or an area of the outlet housing on which the sealing device is arranged is no longer required.
  • a corresponding connection interface on the turbine housing can therefore also be dispensed with. This can reduce manufacturing costs and assembly costs.
  • connection interface surrounds or at least substantially surrounds the housing longitudinal axis.
  • Such a connection interface can be produced with simple means and inexpensively and can be easily mounted on the turbine housing.
  • an inner side of the outflow housing wall facing the drum space has at least one guide vane ring.
  • Guide vane rings are designed to divert the steam mass flow to subsequent rotor blade rings.
  • the object is achieved according to the invention by a steam turbine.
  • the steam turbine has at least a first turbine section, a second turbine section and a turbine housing comprising the first turbine section and the second turbine section, the first turbine section being coupled in fluid communication with the second turbine section via a reheating device.
  • an outflow housing according to the invention is arranged within the turbine housing at an end region of the first turbine section that is rearward in the flow direction of the steam turbine.
  • the first turbine section is preferably designed as a high pressure section and the second turbine section as a medium pressure section or low pressure section.
  • a steam mass flow can be heated to a higher temperature level after leaving the first turbine section and before entering the second turbine section, in order thus to increase the efficiency of the steam turbine.
  • the outflow housing is preferably designed in several parts, in particular in two parts.
  • the outflow housing preferably has an upper part and a lower part.
  • the steam turbine according to the invention has the advantage over known steam turbines that the discharge housing ensures that a relatively cold steam mass flow leaving the first turbine section can be extracted from the turbine without hitting the turbine housing. During operation of the steam turbine, it is thus avoided that the turbine housing has an excessively high temperature gradient in this area, since the turbine housing is essentially exposed to warmer steam due to the discharge of the relatively cold steam.
  • the steam turbine can thus be dimensioned more cost-effectively with the same output. Alternatively, the output of the steam turbine can thus be increased with the same dimensions of the steam turbine.
  • the steam turbine has the advantage that an additional sealing shell, which seals the first turbine section from the second turbine section, is no longer necessary and can therefore be omitted. As a result, the turbine shaft and thus the entire steam turbine can be made shorter and therefore more cost-effective. In addition, a shorter turbine shaft has improved rotor dynamic properties.
  • the outflow housing is arranged on the steam turbine in such a way that a steam mass flow flowing through the drum space can only hit the turbine housing after flowing through the reheating device downstream of the outflow housing.
  • an outflow connector of the outflow housing is coupled to the reheating device directly or in a fluid-communicating manner via a line. It is thus ensured with simple means and inexpensively that, instead of relatively cold steam before extraction, relatively hot steam hits the turbine housing after extraction. Since the steam in front of the discharge casing is also relatively hot, the turbine casing has less temperature differences during operation exposed. Temperature gradients of the turbine housing of a steam turbine according to the invention are therefore lower than in conventional steam turbines.
  • the outflow housing is preferably held on the turbine housing via the connection interface.
  • the turbine housing preferably has a corresponding holding device for this purpose.
  • the connection interface is preferably in positive engagement with the holding device. To fix it, the connection interface of the outflow housing is screwed to the holding device of the turbine housing, for example. The outflow housing is thus held securely on the turbine housing.
  • a steam turbine (3) according to the prior art is shown schematically in a side view.
  • the steam turbine 3 has a plurality of turbine sections 2, which are designed, for example, as a high-pressure turbine stage, medium-pressure turbine stage and low-pressure turbine stage.
  • a guide vane carrier 20 with a plurality of guide vane rings 14 is arranged in each of the turbine sections 2.
  • a central turbine section 2 is delimited in the flow direction S by a sealing shell 21.
  • the sealing shell 21 prevents a further flow of a steam mass flow in the flow direction S and directs it in the direction of the turbine housing 8 and further into an extraction device.
  • An outlet is coupled in fluid communication with a following turbine section 2.
  • This steam turbine 3 has the disadvantage that during operation the steam mass flow deflected by the sealing shell 21, which has a relatively low temperature, flows against the turbine housing 8, with relatively hot steam mass flows in the direction of flow adjacent before and adjacent after the turbine housing 8 stream.
  • the turbine housing is accordingly first exposed to a steam mass flow with a relatively high temperature, then a steam mass flow with a relatively low temperature and finally a steam mass flow with a relatively high temperature. This creates a high temperature gradient in the turbine housing 8, which places a heavy load on the steam turbine 3 and limits a maximum output of the steam turbine 3.
  • a section of a steam turbine 3 according to the invention is shown schematically in a top view.
  • the steam turbine 3 has a turbine housing 8, of which only a lower housing part 8a is shown in this view.
  • the turbine housing 8 extends along a housing longitudinal axis 6, completely surrounds the housing longitudinal axis 6 and thus comprises or delimits a flow space 16 for a steam mass flow to flow through.
  • the steam turbine 3 has a plurality of turbine sections.
  • An outflow housing 1 according to the invention is arranged in a rear end region 15 of a first turbine section 2a in the flow direction S, which is adjacent to a second turbine section 2b.
  • the outflow housing 1 has an outflow housing wall 4, which extends along the housing longitudinal axis 6, completely surrounds the housing longitudinal axis 6 and thus a central drum space 5 includes or limited in the radial direction. Guide vane rings 14 (cf. Fig. 1 ) that are not shown in this view.
  • a circumferential connection interface 7 is formed on an outside of the outflow housing wall 4 facing away from the drum space 5.
  • the connection interface is designed as a circumferential flange which extends radially outward from the outflow housing wall 4.
  • the outflow housing 1 is held or fixed on the turbine housing 8 via the connection interface 7, for example via a screw connection.
  • the turbine housing 8 has a corresponding holding device 17.
  • the outflow housing 1 has a rear end 10 in which a receiving device 11 for receiving a sealing device 9 is arranged.
  • the sealing device 9 is designed to seal the outflow housing 1 from a turbine shaft (not shown).
  • an outflow channel 12 is formed which surrounds the housing longitudinal axis 6. A steam mass flow flowing through the drum space 5 is thus prevented by the sealing device 9 from flowing further in the flow direction S and is directed into the outflow channel 12.
  • Fig. 3 shows schematically in a perspective illustration an upper part 1b of the outflow housing 1 according to the invention Fig. 2 .
  • the upper part 1b extends like the lower part 1a along the housing longitudinal axis 6 and surrounds the housing longitudinal axis 6 by 180 °.
  • the upper part 1b can be screwed to the lower part 1a via a connecting flange 18.
  • the outflow channel 12 also extends in the circumferential direction over the upper part 1b, the outflow channel 12 having outwardly pointing openings at two points, at each of which an outflow nozzle 13 is arranged, which extends approximately tangential direction from the outflow channel 12.
  • the steam mass flow can be conducted out of the outflow housing 1 via the outflow nozzle 13 and is not shown in FIG Reheating device can be supplied without the steam mass flow impinging on the turbine housing 8.
