Subsequently, it flows on its way to the discharge chamber 16 through a second stage 37 and second group of heating tubes 18, concentric is disposed within the first stage 36.
- the outer first stage 36 is by a bleed steam feed line 40 with
- Main steam supplied from a steam generator 66 (not shown) at about 70 bar.
- separating plates 82 may be provided for the separation of the respective vapors. This also applies to the exit collector.
- a ring bundle with a separate tubesheet instead of arranging two tube bundles into one another, it is also possible to use a ring bundle with a separate tubesheet.
- the thus heated in two stages of steam flows into the discharge chamber 16 and from there through the discharge lines 24 to the low-pressure turbine.
- the gaseous fraction is thus heated successively on its way into the interior of the discharge space 16.
- This type of two-stage heating can be generalized to multi-stage heating with the aid of additional steam feeds and tube groups in an obvious manner.
- FIG. 3 In the right-hand side of FIG. 3, an embodiment with single-stage heating is shown.
- the heating pipes 18 are all supplied via the live steam supply line 38 with live steam.
- the fine separator 28 are connected to condensate collecting trays 32, from which condensate drain pipes 34, the condensate is passed through condensate drains 46 from the housing 2.
- condensate drain 43 The flowing down on the inside of the housing 11 condensate, here water, runs in the condensate drain 43 and leaves the housing 2 through a condensate drainage 46.
- a second condensate drain 42 is provided in the recessed bottom region of the housing 2, through which the lower partial space is collected Condensate can drain through a condensate drain 46.
- the embodiments of the cyclone separator 1 shown in FIG. 3 can be combined with the configurations shown in FIG. 1 with ring bundles or individual bundles 20.
- the drier or fine separator 28 is connected to a condensate collecting trough 32, into which the condensate forming in the operating state of the cyclone separator 1 in the drier or fine separator 28 runs. It runs through one or more supply lines 41 through each connected to the supply line 41
- the condensate catch pans 32 can be configured differently depending on requirements.
- each fine separator 28 is assigned a condensate catch basin 32. It is also possible a single one use annular condensate catcher 32 into which the condensate from all fine separators 28 can flow.
- condensate traps 32 are mounted at different heights in the housing 2.
- the condensate collecting trays 32 are mounted in the housing 2 in two different planes.
- FIG. 5 shows a condensate catch basin 32 of the upper level in a plan view of the cyclone separator 1 shown in FIG. 3.
- FIG. 5 shows two supply lines 41 connected thereto on the flow side and condensate drain pipes 34 connected thereto. There are also two more pairs of
- Supply lines 41 and condensate drain pipes 34 can be seen, these pairs are not connected on the flow side with the illustrated condensate catcher 32. Rather, they are connected to the condensate catching basin which lies below, here concealed by the upper condensate catching basin 32.
- the condensate drain pipes 34 which belong to the two condensate catching basins 32 lying at different heights are mounted alternately along the circumference in which they are mounted. The circular curvature is not visible in the completely schematic and not to scale Fig. 5.
- each condensate discharge pipe 34 is connected to exactly one condensate catch basin 32, has the advantage that a high throughput of condensate in the operating state is ensured.
- a plurality of condensate catch pans 32 may be connected to the same condensate discharge pipe 34 on the flow side.
- FIG. It An advantageous embodiment of a steam turbine plant 62 is shown in FIG. It includes a steam generator 66, a high pressure turbine 70, and a
- Low-pressure turbine 74 Low-pressure turbine 74.
- the cyclone separator 1 is connected on the flow side between the high-pressure turbine 70 and the low-pressure turbine 74.
- the live steam generated in the steam generator 66 is directed to perform work in the high pressure turbine 70. By doing work, the steam relaxes in the
- High-pressure turbine 70 which increases its water content. So that the steam in the low-pressure turbine 74 can be used as efficiently as possible for energy production, it must be prepared in a suitable manner. This must be its water content be reduced before it is then transferred to a superheated state. For this reason, the steam exiting from the steam outlet of the high-pressure turbine 70 is conducted via a distributor through supply lines 6 into the housing 2 of the cyclone separator 1. There, the steam flows tangentially to the housing inner side 11 and is thereby set in rotation. The gaseous portion of the steam flows into the housing interior, where it is put into a superheated state by heating elements, in particular heating pipes. From there, the superheated steam is passed through discharge lines 24 into the steam inlet of the low pressure turbine 74.
- the processed in this way steam can be further used for energy.
- the heating tubes (not shown here) of the cyclone separator 1 are supplied in this embodiment by the heating supply line 78 with live steam from the steam generator 66.
- the high pressure turbine 70 could be removed for this purpose bleed steam.
- the cyclone separator 1 is not limited to use in steam turbine plants. It can essentially always be used where the heavier component or phase is to be separated from a multiphase fluid flow and the gaseous fraction is to be heated or superheated.
- the heavy component of the fluid stream can be water as explained above. However, applications are also conceivable in which the heavy component consists of solid particles. This could be, for example, soot or dirt particles.
