Definitions
- the invention relates to a steam power plant with a boiler, a steam turbine, a condenser and a bypass line that bypasses the steam turbine, by leading directly from the boiler to the condenser. It particularly affects one Steam introduction device between the bypass line and the condenser and the first of two vents in this one Steam introducer.
- the steam from the Boiler When starting and stopping a steam power plant and when Steam turbine load shedding due to a shutdown of the plant, the steam from the Boiler not led to the steam turbine because it contains too much water and therefore the would damage the turbine blades. Instead, the steam from the Boiler directly through a bypass line and a steam introducer led the capacitor.
- the steam introduction device is used for relaxation and desuperheating the steam before entering the condenser for condensation reached.
- the steam flowing in via the bypass line has one high flow rate, on the other hand a temperature of up to 600 ° C.
- the temperature in the condenser however, is around 40 ° C. It applies So the temperature of the steam as well as the speed can be greatly reduced. This also means that the components of the steam introduction device are one are exposed to large temperature gradients.
- CH-T 080 273 of the Brown Boveri Companie is one Bypass control valve downstream of a two-stage steam introduction device, which is arranged in the capacitor.
- the first stage of the steam introducer consists of a steam passage cover, a perforated cover in the shape of a Truncated cone, through which the hot steam stream is sprayed and fanned out. After the pinhole, it enters a relaxation or de-heating chamber.
- a pinhole of the first stage of the steam introducer is off finished several flat components, namely a part for the jacket of the Truncated cone, a closing part for the tip of the cone and one Transition part for the connection to the end of the bypass line.
- the openings the pinhole is drilled in the still flat part of the cone shell, the is then hot formed into a cone and welded together.
- the Final part for the tip of the cone is then with the truncated cone and that The transition part is welded to the end of the bypass line.
- the task is accomplished by a steam introduction device according to the preamble of the first claim solved, the pinhole from a single spherical Part exists.
- the main advantage of a pinhole of this type is the increased mechanical Stability and thermal resilience of the pinhole and the achieved with it Operational safety of the steam introduction device. This is also the Operational reliability of the entire power plant increased because of a longer one Operating time of the device is guaranteed without repairs.
- a spherical shape is mechanically more stable.
- the selected form of the aperture thus grants one in comparison to the prior art increased mechanical stability.
- the aperture according to the invention has a smaller wall thickness than the conical, the stability required for the panel is nevertheless guaranteed.
- a Smaller wall thickness also has the advantage that the through the Thermal gradients caused by thermal stresses in the material are smaller are. As a result, the thermal load capacity is significantly increased and the Aperture susceptibility to breakage reduced.
- the openings of the pinhole are such arranged so that each opening is equidistant from each nearest opening. This also results in a uniform material thickness and thermal Stability of the panel.
- the one-piece, spherical diaphragm is produced by a pressing process. After After reaching the desired shape, the workpiece is annealed and checked cooled and relaxed. The end product points through this manufacturing method minimal material stresses, which increases the thermal resistance of the panel is favored in operation.
- a second advantage is the cost reduction for the manufacture of the pinhole. This is done primarily by reducing the number of parts to a single part and the number of processing steps achieved. There is only one to manufacture the cover Pressing process is necessary, and welding processes are no longer required. It there is no separate production and assembly of a closing part, as is the case with cone-shaped pinhole was the case, and especially one Transition piece between the pinhole and the end of the bypass line.
- the spherical pinhole has a straight rim, the diameter of which The diameter of the bypass line is adjusted.
- FIG. 1 shows a cross section of a steam introduction device 1 in a Steam power plant.
- a bypass line 2 leads from a not shown Boiler of the system for steam introduction device 1. This is with the Capacitor 9 connected, in the condenser neck 7 of the capacitor 9 protrudes.
- hot steam is emitted from the boiler according to the direction of the arrow a temperature of over 500 ° C through the bypass line 2, whereupon it a first pinhole 3 of the steam introduction device hits.
- the steam arrives through openings in the pinhole 3 and is thereby fanned out.
- the Pinhole aims to expand the steam flow as much as possible so that it fills the subsequent desuperheating chamber 4 as far as possible.
- the steam through Mixing with the water is heated.
- the steam is in the chamber relaxed due to turbulence.
- This second Pinhole 8 is semi-cylindrical in shape, with the cylinder in the plane of Drawing protrudes and protrudes from the plane of the drawing.
- the Pinhole 8 causes a regular distribution of the cooled steam in one level in the condenser neck 7 above the tube bundles 10. This level becomes the steam is sucked into the condenser 9 and on the cooling pipes in the Tube bundles 10 condensed.
- FIG. 2 shows the first pinhole 3 according to the invention in detail.
- the pinhole 3 has the shape of a basket arch floor in this version. This form is for Example also known under the German industry standard number 28013. she is characterized in particular by the spherical central part, which creates the aperture has increased mechanical stability. It is therefore with thinner walls executed and still has the necessary stability.
- the basket arch floor with the straight board is manufactured in a single pressing process.
- the openings 12 are made after the pressing process by means of a programmable, on five axes working drilling machine (NC machine) drilled. With this way of working it is achieved that the axes of the openings 12 are each in the same center to cut. This orientation of the openings 12 makes it more uniform
- NC machine five axes working drilling machine
- the straight shaped board of the The arched floor is welded directly onto the end of the bypass line 2.
- the arrangement of the drilling openings 12 of the perforated diaphragm 3 according to the invention is shown in FIG Figure 3 shown. It is characterized in that the distance between adjacent openings 12 is the same in each case. This will make the mechanical Stability favored over the entire area of the aperture.
- the coordinates of the Openings are made according to the curvature of the basket arch floor and the required diameter of the openings calculated and directly the NC machine fed for manufacturing.
- the pinhole protrudes less far into the Desuperheating chamber as a conical aperture. This has the advantage that Water droplets in the condensate line after switching off the condensate nozzles 6 located and fall into the desuperheating chamber, not on the hot pinhole reach. Such drops would otherwise cause local thermal shock and possibly cause a resulting erosion of the screen.
