Definitions
- the invention is a condenser neck, which between a steam turbine and one downstream of the steam turbine Capacitor is arranged.
- EP-A1-384 200 is an arrangement of a steam turbine and a subsequent steam condenser known. Between the two Elements that are arranged in one level are included Evaporation nozzle and a condenser neck. The steam from the steam turbine becomes the tube bundles via the evaporation nozzle and the condenser neck of the capacitor. This condenser neck essentially has that Task, a homogeneous flow field and a clean steam purging the bundle of the capacitor arranged below. The The condenser neck of this steam condenser widens conically from Evaporating nozzle to the condenser.
- condenser necks consist of flat plates consist. Since very large vacuum forces act on the condenser neck he is reinforced inside by pipes. Occasionally ribs are added attached to the outside. These pipes are necessary, they disrupt the Flow of the steam, however, considerably. On the side away from the flow the tubes form little advantageous vortices, which the Excite support tubes and thus the entire condenser neck. A failure the support pipes up to the total failure of the system and damage to all involved components may result. In a bypass operation, ie the introduction of hot steam directly into the condenser neck Bypassing the turbine, for example in the event of a sudden shutdown the turbine, there are overall difficulties in introducing steam. It there is a risk of erosion of the support pipes and the walls. Through the The large number of pipes used is a complex assembly of the Sheets, pipes and fins required by welding. This kind of Capacitor necks is through the use of flat plates too fluidically shaped little advantageous.
- the aim of this invention is to avoid the disadvantages mentioned.
- the Invention solves the problem of constructing a condenser neck which has increased stability to external influences, the Flow of the steam is influenced or disturbed as little as possible should.
- the capacitor neck 1 according to the invention of FIG. 1 consists of two levels Cover plates 2 and two side walls 3, which are between the Cover plates 2 are.
- the side walls 3 expand from one Inlet opening 9 to an outlet opening 10 of the condenser neck 1 in a flow-wise favorable form, for example, as in FIG. 1 shown, in the form of a nozzle, a diffuser or the like.
- the Flow direction of the steam 6 is in the direction of the arrow from the inlet opening 9 to the outlet opening 10.
- Both the cover plates 2 and the side walls 3 are by ribs 4a, 4b reinforced.
- a vertical tube 5 is provided in the center, which is also used for reinforcement the condenser neck 1 is used.
- the tube 5 is about in the last third Outlet opening 10 of the condenser neck 1 is provided.
- the tube 5 is thus installed at a point where there is only the steam flow slightly influenced.
- the ribs 4a on the cover plates 2 are star-shaped arranged around the tube 5.
- the horizontal ribs 4b of the side walls 3 are approximately parallel to the (main) flow direction of the steam 6 aligned.
- the vertical ribs 4b are perpendicular to the horizontal Ribs 4b.
- the horizontal ribs 4b act in this Case reinforcing.
- the side walls 3 are installed so that on the Entry opening 9 creates a connecting surface 7 on each side. This Connection surfaces 7 serve for fastening on the turbine side and thus at the same time to absorb external loads. Vacuum, earthquake, Pipe or other turbine-side forces are over the Transfer connection surface 7 and in particular by stiffened Side walls 3 and cover plates 2 added and not on the shown capacitor jacket forwarded.
- the acting force distributes in this way in the condenser neck 1 according to the invention evenly over the circumference.
- the condenser neck 1 can be connected with an axial or lateral arrangement of steam turbine and Capacitor are used.
- FIGS. 2 and 3 show two further views of the condenser neck 1.
- Figure 2 which represents a top view, becomes the star-shaped one Arrangement of the ribs 4a on the condenser neck 1 around the tube 5 and aerodynamic shape of the side walls 3 clearly.
- Figure 3 represents one Side view of the condenser neck 1.
- Fig. 4 shows a section along the line IV-IV of Figure 3 through the capacitor neck 1 according to the invention. It is clear that both in the tube 5, as well as in the side 3 and / or top walls 2 openings 11 can be present, which with a bypass line, not shown are connected. These bypass lines are used in the case of a Shutting down the steam turbine bypassing the turbine direct into the condenser. Because the number of themselves inside located elements compared to the known prior art clearly is reduced, there is a risk of erosion from the introduced steam reduced. Due to the central arrangement of the tube 5, the danger is Erosion of the side walls 3 also reduced. The arrangement of the Openings 11 for the bypass lines in the tube 5 are also advantageous, because it has a very large surface area for this purpose.
