Definitions

  • the invention relates to a condenser, in particular a steam condenser for use in a steam turbine plant.
  • Capacitors for condensing a vaporous fluid are used in a variety of ways in technology.
  • condensers for condensing a wide variety of fluids are often found in conjunction with reaction columns.
  • a very important area of application for condensers is also the use in steam turbine systems, in particular in power plants.
  • one or more condensers are generally used in the flow path of the working fluid of the steam turbine process at the outlet of the steam turbine or, if several are used, in series switched steam turbines, arranged behind the steam turbines.
  • the steam comes from an evaporator (boiler of the steam turbine system) and then flows through the steam turbine and ultimately into the condenser, releasing energy.
  • the condenser arranged in a steam turbine plant represents a very essential the cyclic process parameters and thus also determining the efficiency Component of the steam turbine process. So it turns out in direct Dependence of the pressure loss of the fluid (here e.g. steam) during the passage through the condenser the outlet pressure at the outlet from the steam turbine.
  • the fluid in the steam turbine can accordingly only up to this outlet pressure relax, thereby releasing the energy of the fluid to the turbine and thus the efficiency of the turbine is limited. For this reason it has long been sought to provide capacitors that one cause the lowest possible pressure drop on the steam side, thus a higher one average heat transfer coefficient is reached.
  • a capacitor other parameters must be taken into account at the same time. In particular the construction volume of a capacitor is often limited.
  • a very important criterion in the basic design of a capacitor is in particular also the possible usability of the capacitor for Different operating and performance states of a system (full load, partial load) as well as use in different systems with different performance requirements.
  • Church Window Bundle (Church window bundle)
  • the condenser usually consists of several (tube) bundles, each Bundle consists of a large number of individual tubes. The exact number and arrangement the tube bundle were here from the point of view of a minimal Pressure loss of the inflowing and condensing steam developed.
  • the tube bundles can be developed in advance in standardized dimensions become. Depending on the respective application and the required performance or throughput is only the number of required Bundle of a capacitor as well as the length of the tubes varies. Within certain limits the diameter of the pipes can also be changed.
  • the individual Designing a capacitor can thus be extremely inexpensive and quick respectively.
  • the object of the invention is therefore modular one of one or more bundles built-up capacitor, preferably one according to the church window concept executed capacitor to provide, the number of Pipes in a bundle without serious loss of performance the previous limit of around 5400 pipes.
  • this is in at least one bundle of the capacitor Condensate drainage element arranged, which preferably with the isobars the flow of fluid flowing around the tubes is approximately a right angle includes.
  • the capacitor comprises one or more bundles, each bundle again comprises a plurality of tubes arranged parallel to one another and is preferably designed according to the church window principle.
  • the pipes can preferably be horizontal but also vertical or at an angle be arranged inclined.
  • the tubes are filled with a first fluid flows through and flows around a vaporous fluid, which as a cooling fluid first fluid used generally has a lower temperature than the vaporous fluid. Due to the heat transfer between the first Fluid and the vaporous fluid condense the vapor as it passes through the bundle.
  • the condensate preferably hits the pipes down and drips or runs down due to gravity.
  • Bundles have a large number of tubes arranged one above the other, occur that the lower tubes completely or almost completely from one Fluid film of the raining condensate are enclosed.
  • the between the upper sector and the lower sector arranged condensate drainage element collects condensate dripping from the upper sector and conducts it this condensate along the condensate drain element.
  • the one in the bottom Pipes arranged below the condensate drain element are thus experienced a significantly reduced condensate load, which leads to loss of performance of the capacitor can be significantly reduced.
  • the condensate collecting tray is in the bundle so that it is aligned with the isobaric lines (if none exist Condensate drain elements) of the steam flow flowing around the pipes approximately right angle. This ensures that the Pressure curve that the condensate along the condensate drain from the Steam flow is impressed, has no discontinuities. Is the condensate drainage element here arranged so that the condensate in the direction of If the pressure drops, the condensate is removed by the embossed one Pressure drop additionally promoted.
  • the condensate drainage element as a condensate drainage surface, particularly preferably as a condensate drainage plate, executed.
  • a condensate drainage surface With horizontally or approximately horizontally arranged pipes of the bundle, it is also advisable to use the condensate drainage surface in each case to attach to support plates of the bundle.
  • the condensate drainage surface extends each advantageous over the entire range between two Support plates. The mostly designed as perforated plates support plates Supporting the tubes of a bundle. Usually there are several in a bundle Support plates each at a certain distance from each other along the tubes arranged.
  • the condensate drainage surface arranged according to the invention in the bundle has a first surface and a second surface opposite the first surface Surface on.
  • the first surface faces upwards, i.e. from the top Sector dripping condensate collects on the first surface on.
  • the condensate drainage surface is advantageously arranged in the bundle in such a way that the distance of the first surface to those facing the first surface Pipes is greater than the distance between the second surface and that of the second Pipes facing the surface.
  • the ratio of the distances is here preferably two to one. This ensures that a sufficient large distance between the first surface and that of the first surface facing pipes is given to an undisturbed drain of the condensate to ensure along the condensate drainage surface.
  • the condensate drainage element in such a way that the condensate from the inside of the bundle to the outside of the bundle is guided and from here via a so-called main alley of the capacitor in a condensate collector flows.
  • the free condenser space becomes the main alley called next to the tube bundle.
  • it is too useful especially if a cavity is arranged in the bundle and this Cavity connected to a main alley or the condensate collector is the condensate by means of the condensate drainage element in this cavity feed.
  • condensate drain channel has at least one condensate inlet opening and at least one condensate outlet opening.
  • the condensate drain channel so arranged in the bundle that condensate that is inside of the bundle is led out of the bundle by means of the condensate drainage channel becomes.
  • the condensate enters through the condensate inlet opening Condensate drain channel and becomes the condensate outlet opening in the condensate drain channel guided.
  • condensate preferably in one of the main streets of the condenser. It it is also possible that condensate is initially arranged in the bundle Feed cavity and from there into one of the main streets or in to conduct a condensate collector. By means of a condensate drain it is thus possible to find condensate that is inside the bundle at the condensate inlet opening accumulates to lead away to the outside. That in the sector below The condensate raining from above of the condensate drainage channel is thus over reduced the portion paid.
  • the condensate outlet opening is preferred with a pipe extension, so that the condensate in the form of a jet is released outside and dripping or injecting into the underlying Pipe bundle is avoided.
  • An air cooler box is preferred, which is above an air cooler of the condenser is arranged as a condensate drain.
  • the task of one Air cooler in a condenser consists of that after passing through the multitude of tubes of the bundle has not yet condensed gas-vapor mixture continue to cool in order to condense the steam as completely as possible to achieve.
  • the rest of the non-condensable gas for example in the case a closed steam turbine process via seal leakage in the Steam circuit has reached, is then extracted from the Aspirated water circuit of the steam turbine process.
  • Air cooler box on the air cooler can be due to the anyway required Separation of the remaining tubes of the bundle from the air cooler even if it is already there designed capacitors simple to implement, without this disrupt the arrangement of the tubes of the bundle.
  • the other tubes from the air cooler are provided with a separating plate on the air cooler, so that an inflow of the gas-steam mixture into the air cooler only through special openings.
  • FIG. 1a a front view of a device known from the prior art Condenser bundle 10 shown, which is designed according to the church window principle has been.
  • Characteristic of a bundle based on the church window principle is a slim tube arrangement with a height of about four times as large Bundle compared to its maximum width.
  • the one shown in Figure 1a Bundle 10 comprises a plurality of horizontally arranged tubes, each parallel to each other. The tubes are offset from one another Rows arranged side by side and one above the other. Due to the staggered arrangement of the pipes, the steam to be condensed must pass through the Dodge the bundles from the tubes of the next row. This is where it comes from to a largely uniform distribution of the steam flow in the bundle.
  • the individual tubes are not shown, but for the sake of clarity just the layout scheme.
  • the crossing points of the arrangement lines reflect the positions of the pipes.
  • the arrangement scheme in The shape of a matrix structure is usually specified by support plates that are in simple way as perforated plates with one corresponding to the number of tubes Number of openings are made and each at certain intervals are arranged along the bundle longitudinal extent.
  • the tubes are each through the openings in the support plates and are inserted supported by the support plates.
  • the arrangement of the support plates is in figure 1a not shown.
  • FIG. 1a Another typical characteristic of a bundle of church windows is the in Figure 1a shown two-stage air cooler 20.
  • the air cooler is approximately on Height of the waistline of bundle 10, i.e. slightly below the geometric center of the bundle 10, arranged and divided the bundle into a lower portion 14 and an upper section 16.
  • the air cooler shown in Figure 1a 20 is mirror-symmetrical with respect to the central plane of the bundle. It would also be possible here, of two arranged mirror-symmetrically to each other To talk to air coolers. Since the arrangement of the tubes shown in Figure 1a Bundle also mirror-symmetrical with respect to the central plane 30 of the bundle , the bundle can thus be divided into a left half 32 and a mirror image of this right half 34 can be divided.
  • Both halves of the air cooler 20 are each built in two stages, whereby they each a first area 22 in which the gas-vapor mixture entering the air cooler is further cooled, and a second area 24 in which the non-condensable gas is collected and eventually exhausted.
  • the suction device is not shown in Figure 1a.
  • the areas of the air cooler are from the other tubes of the bundle by means of an air cooler housing or separated by means of separating plates in order to allow steam to flow in directly to prevent the air cooler.

  • the one symmetrical in the middle of the bundle cavity 40 arranged to the central plane of the bundle extends about half the height of the bundle 10.
  • Free cavity 40 which is also referred to as a steam lane, serves in one after bundles designed according to the church window principle, about the same large pressure loss of the steam flow regardless of the inflow into the Ensure bundles.
  • the steam thus has along its flow path up to to the air cooler, regardless of where it flows into the bundle, anywhere about the same hydraulic resistance, i.e. Flow resistance, too overcome. This ensures that steam does not prefer over a Flow path but flows evenly into the bundle.
  • the bundle 10 shown in Figure 1a is steamed from above, for example comes from a steam turbine.
  • the steam distributes itself accordingly of the flow vectors 50 drawn in by way of example in FIG. 1a to all Sides of the bundle 10 and also penetrates into the bundle 10 from all sides. In this way, an optimal flow through the bundle is achieved, in which the distribution the steam on the pipes is largely uniform. Bad or Areas of the bundle that are not flowed through can thus be avoided.
  • Capacitor occurs as a result of the flow of the bundle from all sides as well as a result of placing the air cooler at the level of the condenser belt negative supercooling of the condensate, i.e. the temperature of the Condensate is higher than that corresponding to the pressure at the condenser level Saturation temperature.
  • the physical reason for this lies in the different Flow rates of the steam on the bottom of the bundle compared to the flow rates of the steam on the top of the bundle with the resulting pressure difference of the steam on the Bottom of the bundle compared to the top of the bundle.
  • a negative one Subcooling of the condensate is usually desirable.
  • FIG. 1b isobars of the steam flow are in the bundle designed according to FIG. 1a drawn.
  • the concentric arrangement is clearly visible the unimodal pressure depression lines around the bundle axis in front of the air cooler 20.
  • In the steam lane 40 occurs due to the acceleration of the steam flow an additional pressure reduction of the steam flow to the air cooler.
  • FIG. 1c shows a schematic representation of the construction of a capacitor, in the six bundles 10a-10f arranged according to the church window principle are.
  • the bundles are loaded with steam from above.
  • the condensate collects in a condensate collector located below the condenser 42.
  • the bundles are arranged so that between the bundles in each case there is sufficient space to allow the steam to flow undisturbed to ensure the individual bundles.
  • the space between two Bundling is called Dampfsburggasse 44.
  • FIG. 1c is the modular design of the capacitor, since the capacitor has no major Design bundles expanded or reduced by additional bundles could be. It is therefore easily possible to adapt the capacitor to special requirements, such as a required revenue conversion.
  • FIG 2 is a capacitor bank 10 designed according to the invention, the was designed according to the church window principle.
  • condensate drainage elements are arranged according to the invention. This one The bundle shown has a height of approximately 6 m and a width of approximately 1.5 m on.
