Definitions

the invention relates to a turbine drainage device, in particular for a steam turbine, with a pressure-resistant housing wall for delimiting pressure chambers for receiving blade rows arranged along a pressure gradient prevailing in operation against an ambient space.
condensation preferably occurs with a strong relaxation of the working steam and in a low load range, especially the low-pressure part of a steam turbine is susceptible to condensation of the steam. Condensation is detrimental in many ways as it aids rusting and galling and also negatively affects the performance of the steam turbine. Therefore, the condensed water should be removed from the turbine before it causes damage and significantly reduces the performance of the turbine.
a turbine dewatering device of the type mentioned in the introduction which according to the invention has a dehydrating means for conducting condensed water within the housing wall parallel to the pressure gradient. Lines outside the housing wall can be saved and the turbine dewatering device can be kept compact. By guiding the condensate within the housing wall also entrained steam can be kept within the housing wall, so that an undesirable discharge of steam can be kept at least low.
the housing wall may be a wall of an inner housing of the turbine.
the ambient space may be an environment of the turbine.
the boundary comprises a pressure delimitation, so that during operation of the turbine within the housing wall a higher pressure prevails than outside the housing wall.
the pressure chambers expediently comprise at least one guide blade carrier, which in particular supports a number of rows of guide blades against the housing wall.
the pressure differential is created by the flow of the working steam and the rows of blades opposing the flow of steam so that the working steam flows from a higher pressure region into a lower pressure region.
the dehydrating agent directs the condensed water along the pressure gradient, ie from a region of higher pressure into a region of lower pressure within the housing wall.
the pressure chambers are connected to each other by a lying within the housing wall portion of the dehydrating agent. Condensation can be passed from one pressure chamber to another pressure chamber - expediently to an adjacent pressure chamber - without having to lead the condensate, and thus also working steam, out of the turbine housing.
the dehydrating agent connects all the pressure chambers of the turbine with each other.
condensation water from all pressure chambers can be connected within the housing wall to form a stream, so that separate lines can be saved.
Condensation can be passed through all the pressure chambers, from the highest pressure chamber to the lowest pressure chamber of the turbine.
a particularly simple and cost-effective management of the condensate along the pressure gradient can be achieved if the pressure chambers are separated by a pressure-resistant separation unit and the dewatering agent has a channel through the separation unit.
the condensed water can flow without auxiliary from the pressure chamber of higher pressure to the pressure chamber of lower pressure, whereby it is pressed by the pressure gradient through the separation unit.
a further advantageous embodiment of the invention provides that the turbine dewatering device has a web for receiving a guide vane carrier, wherein the dewatering means comprises a drainage channel in the web.
the drainage channel can be easily manufactured, in particular without having to be introduced into the guide vane carrier.
the inclusion of the vane support may be accomplished by the vane support encompassing or engaging the land.
the web is suitably connected directly to the housing wall, for example, welded.
the drainage channel can be introduced at the lowest point of the respective pressure chamber, so that the pressure chamber can be completely drained.
the dewatering agent in a further embodiment variant of the invention has a valve arranged within the housing wall.
the valve may in this case be arranged within the space occupied by the housing wall or within the space enclosed by the housing wall.
the valve is disposed within a separation unit separating two pressure chambers so that the passage of condensed water from one pressure chamber to another can be controlled.
a simple production of the turbine dewatering device can be achieved if the valve is arranged in a drainage channel extending within the housing wall and can be inserted from outside the housing wall into the dewatering channel.
a maintenance or replacement of the valve can be performed easily and inexpensively, for which purpose the valve is expediently removable from outside the housing wall from its working position.
Simple control of the valve is achievable if the valve is controllable from outside the housing wall.
the condensate is advantageously recycled to the circulation.
a convenient place to feed the condensate in the water-steam cycle is a condenser of the turbine system.
piping can at least largely be dispensed with when the dehydrating agent extends within the housing wall to the capacitor.
a control unit for controlling a dehydration of the pressure chambers for example a computing unit for controlling a valve.
a water level or an amount of water in a pressure chamber can be measured with a water sensor and it can be dewatered depending on the water level or the amount of water. Also conceivable is drainage at predetermined time intervals.
the amount of condensed water generated may be determined depending on operating modes of the turbine, steam temperatures or pressures and stored in the control unit so that it controls dewatering according to the deposited data and e.g. sets a duration of a dehydration period and a non-dehydrated period accordingly.
the pressure chamber In a drainage of a pressure chamber in another pressure chamber, that is, a discharge of condensed water from a pressure chamber into the other pressure chamber, the pressure chamber is dehydrated in addition to the resulting in this pressure chamber condensate with the condensate of the dewatered pressure chamber acted upon.
the pressure chamber In order to avoid too high a level of the pressure chamber into which is dewatered, the pressure chamber is advantageously first dehydrated before being dehydrated into it.
the control unit is provided in a further embodiment to first dewater a pressure chamber of low pressure, then to drain a pressure chamber of higher pressure in the pressure chamber of low pressure and then to further dehydrate the pressure chamber low pressure.
the further drainage can be carried out as a continuous further or renewed further drainage. For drainage, it is sufficient to remove condensation from one Remove pressure chamber, the pressure chamber must not be completely emptied.
control unit is provided to dehydrate at a drainage of a pressure chamber of higher pressure in a pressure chamber of low pressure these inevitably expediently before dehydration into it.
FIG. 1 shows a steam turbine 2 in a sectional view, which has a housing 4 with a pressure-resistant housing wall 6 for pressure-tight shielding of pressure chambers 8, 10, 12 against an ambient space 14 outside the housing wall 6.
a rotor with a shaft 16th rotatably mounted, which carries a number of blade rows 18.
the blade rows 18 together with rows of guide blades 20 are part of three blade stages 22, 24, 26, in which the blade rows 18 engage between the rows of stator blades 20.
Each of the vane stages 22, 24, 26 has a vane support 28, 30, 32 which carries the vane rows 20 and is fixedly connected to the housing wall 6.
the steam flows through rows of blades 36 of the second blade stage 24 designed as a medium-pressure stage, where it is further expanded and fills the third pressure chamber 12, but with even lower pressure than the second pressure chamber 10.
After a final flow through blade rows 38 of the third blade stage 26 designed as a low-pressure stage The steam passes substantially relaxed via a steam outlet 40 in a condenser 42 shown only schematically, in which it is condensed before being reheated for a new pass through the steam turbine 2. Due to the different pressures in the pressure chambers 8, 10, 12, a pressure gradient 44 is formed within the housing 6, which is indicated schematically by an arrow.
the pressure chamber 12 is endangered by condensation, which there - preferably at a low power of the turbine 2, in particular less than 20% of the rated power - increasingly reflected. This condensation can cause a cooling of lower parts of the housing wall 6, which can form undesirable thermal stresses there.
a dehydrating agent 46 is provided, the six Drainage channels 48, 50, 52, 54, 56, 58 by webs of the housing wall 6, through which the condensation can flow.
the drainage channel 48 connects the pressure chambers 8 and 10 with each other and the drainage channel the pressure chambers 10 and 12.
the drainage channel 52 leads without pressure gradient through a housing web.
the drainage channels 54, 56, 58 connect the pressure chamber 12 to the steam outlet 40.
the drainage channels 48, 50, 54, 56 each connect spaces with each other in which there are different pressures during the operation of the steam turbine 2.
a respective valve 60 (see FIG. 2) is introduced into each of these drainage channels 48, 50, 54, 56, with which the respective drainage channel 48 , 50, 54, 56 can be closed or opened.
FIG. 2 shows a detail of the housing wall 6 in the region of the drainage channel 50.
the housing wall 6 includes there a circumferential web 62, in which a groove 64 is introduced.
this groove 64 designed as a holding plate further web 66 is welded, which engages in the guide vane carrier 30 and holds it in its axial position.
the drainage channel 50 is guided by the web 62 and the web 66, in such a way that it extends radially outside of the guide blade carrier 30, so that it can remain unchanged despite the channel 50.
the drainage channel 50 is disposed at the lowest point of the pressure chamber 10, so that it can be completely emptied through the drainage channel 50.
the valve 60 shown only schematically is inserted from radially outside through an opening 68 in the drainage channel 50 and screwed, for example, in the housing wall 6.
a control line 70 it is connected to a control unit 72, which opens and Close the valve 60 after a program or on a manual input of an operator controls out.
the valves in the drainage channels 54, 56 are first opened by the control unit 72, so that the lowermost pressure chamber 12 is dewatered. If the pressure chamber 10 is to be dehydrated, then the valve 60 is opened in the drainage channel 50, so that the pressure chamber 10 is dewatered into the pressure chamber 12. The valves in the drainage channels 54, 56 remain open until the pressure chambers 10, 12 are completely or substantially dehydrated. If the pressure chamber 8 is to be dehydrated, after dewatering the pressure chamber 10, the valve in the dewatering channel 48 is opened and the pressure chamber 8 is dewatered into the pressure chamber 10, which is dewatered at the same time or subsequently into the pressure chamber 12.
the underlying pressure in the pressure chamber 10, 12 is always dewatered, so that can not collect condensation from two pressure chambers 8, 10, 12 in a pressure chamber 10, 12.
these are all connected via control lines 70 to the control unit 72.
the drainage of the pressure chambers 8, 10, 12 can be controlled by means of sensors, not shown. It is also possible to drain without detection of the Water level using flat periodic or calculated drainage times.
the control unit 72 may be supplied with data on the steam temperature and / or the steam pressure, which calculates therefrom an expected condensate formation for the individual pressure chambers 8, 10, 12 and triggers a dewatering according to a predetermined condensation threshold.
