Definitions

  • the present invention relates to a tube sheet for receiving pipes of a Nachschaltebenleyers for a boiler, in particular a condensing boiler, for cooling and condensing of exhaust gases of a burner of the boiler. Furthermore, the invention relates to a Nachschaltebenleyer with such a tube sheet.
  • second heat exchanger for boiler indicates that the heat exchanger is connected downstream of a boiler. It is also customary to designate such heat exchangers as “residual heat exchangers”.
  • Tube bundle heat exchangers which are supplied with various gaseous and / or liquid media of different temperatures on their tube and shell side (channel side), are required for numerous processes in a wide variety of technical applications.
  • the exhaust gas of the burner of the boiler can be cooled so far that the water vapor components of the exhaust gas, which arise in the combustion of hydrocarbonaceous fuels in the burner, condense.
  • the calorific value utilization is often achieved by lowering the inlet temperature of the heating water into the heat exchanger (return temperature) to such an extent that the dew point of the exhaust gas at the heat exchanger surfaces is undershot.
  • the number of appropriate Way coincides with the number of tubes of the Nachschaltebenleyers.
  • the openings are designed to receive the tube end sections of the tubes.
  • the fastening can be carried out in such a way that the pipe end regions are inserted through the opening and a part of the pipe end regions protrudes from the side of the at least one pipe bottom facing away from the pipes.
  • To seal the heat exchanger sealing means between the outer jacket of the tubes and the openings can be provided.
  • the tubes are mounted in the manner in which at least one tube sheet, that the pipe ends are not completely inserted through the opening, but end within the opening, or flush with this. This can be done for example by means of a press fit of the tubes in the tube sheet. If necessary, sealing means can also be provided in this type of fastening.
  • secondary heat exchangers have two tubesheets, each tube plate receiving one end of each tube.
  • the tubes are normally rectilinear.
  • the individual tubes are U-shaped and the tubesheet receives both ends of each tube.
  • tubesheets are in some cases subject to very high kinetics and thermal loads, which often leads to deformations or damage to the tubesheet in the case of tube sheets made of plastic. Furthermore, due to the deformation of the tube bottom, there may also be tensions in the tubes held in the tubesheet, which in turn may cause damage to the individual tubes. This is especially the case with tubes made of glass.
  • tubesheets were made of steel. As a result, it was achieved that the occurrence of damage to the tubesheet or to the tubes was reduced by kinetic and / or thermal stresses during the operation of the secondary heat exchanger. However, a complete avoidance of such stresses related material tension can not be achieved by such a tube sheet. Furthermore, such existing steel tube sheet is relatively expensive to produce.
  • the invention has for its object to provide a tube sheet of the type mentioned, with the occurrence of material stresses due to occurring during operation and acting on the tubesheet loads, for example. Kinetic and / or thermal nature, further reduced and that is easy to make.
  • the core idea of the present invention is therefore to make the tube sheet multilayer, wherein at least two of these layers are made of metal.
  • the individual views are connected to each other and thus form a solid bond, which in turn forms the tube bottom.
  • the occurrence of material stresses by kinetic, thermal or other stresses during operation of the heat exchanger is further reduced, since an existing of a multilayer composite tube sheet can better absorb external stresses as a one-piece tube sheet.
  • the formation of at least two layers of metal ensures sufficient overall stability of the tube sheet.
  • the production of the tube sheet against a tube sheet made of a solid piece simplified, since only partially to be provided design features of the tube sheet, for example. Grooves for receiving seals, openings for fixing the tube sheet, etc., must be formed only in individual layers. This simplifies the manufacturing process.
  • the tubesheet can be formed of any number of layers, wherein at least two layers must be present.
  • the individual layers are expediently designed as plates, which advantageously have substantially the same dimensions and are joined together to form the tube bottom.
  • the connection of the individual plates can be brought about by means of any known from the prior art and suitable fastening means, for example. By welding and / or riveting.
  • the individual plates can be produced in the form of sheets.
  • loads acting on the tubesheet can be better absorbed by the multi-layer tubesheet according to the present invention than by a one-piece tubesheet, since the plates form a firm and stable composite towards the outside but have a certain amount of deformation relative to each other that material stresses can be better absorbed.
  • the condensate (“acidic condensate”) in the condensing boiler attacks the materials of the heat exchanger and thus also the tubesheet.
  • the condensation pollutants and acids such as sulfuric and nitric acid incurred. This Acid attack can lead to corrosion of the metal layers of the tube sheet according to the invention.
  • one of the outer layers of the tubesheet is made of a corrosion resistant material.
  • the tube plate is expediently to be arranged in the heat exchanger in such a way that the corrosion-resistant outer layer of the tube plate faces the tubes of the heat exchanger and thus its inner region.
  • the corrosion-resistant outer layer of the tube plate is arranged on the exhaust side.
  • Such an embodiment accordingly consists of at least three layers, two metal layers and a layer of corrosion-resistant material.
  • Another advantage of this embodiment results from the fact that the layer of corrosion-resistant material can be formed as a separate plate, which can be produced separately from the metal plates. After production, this is connected to the metal plates. Thus, the production is generally easier than this z. B. would be the case if a metal tube bottom would have to be coated with a corrosion-resistant sheath.
  • the corrosion-resistant material is a particularly good and favorable corrosion protection can be produced in this way.
  • the plastic is a thermoplastic, more preferably polytetrafluoroethylene, which is also known under the trademark "Teflon®". Due to its chemical properties, polytetrafluoroethylene is particularly well suited for use in corrosion protection and also has good temperature resistance.
  • each individual layer of the tube bottom correspond in each case to the openings in the other layers in such a way that each individual opening of one layer together with the respectively associated openings of the other layers has a receiving opening for Recording a tube of the heat exchanger forms.
  • the openings of the individual layers are arranged one behind the other in the axial direction of the heat exchanger, so that the individual tubes can be inserted through all the openings of the individual layers.
  • a seal in particular an O-ring, in each receiving opening of the tube bottom.
  • the individual seals are arranged in such a way between the metal layers that they are held there by means of a positive connection and / or a frictional connection, in particular by clamping or press fit. This has the advantage that no further attachment means o. ⁇ . Are necessary for holding the seal.
  • the sealing ring is held in the individual receiving openings characterized in that in a middle metal layer or plate of the tube plate, the individual openings are formed such that they can accommodate the sealing ring. That is, the diameter of the openings is equal to or larger than the outer diameter of the seal rings.
  • the thickness of the middle metal plate is dimensioned such that it corresponds approximately to the thickness of the sealing ring, so that the plate can completely absorb the sealing ring in their openings.
  • the openings of the metal plates adjoining the middle metal plate are formed to have a smaller diameter than the outer diameter of the sealing rings.
  • the individual metal plates lie flush against each other, so that the sealing ring in the opening of the middle plate is held firmly by the adjacent to both sides plates. If the thickness of the middle plate chosen smaller than the thickness of the sealing ring, in addition results in a frictional connection in the form of a press fit. In this embodiment, a safe and spatially stable introduction of O-rings can thus be achieved by simple design measures.
  • the stop is formed in that the diameter of the individual openings of the outer layer with respect to the diameter of the openings of the other layers is smaller. Also, the diameter of the openings of the outer layer must be smaller than the pipe diameter. In this way, a stop can be provided by simple design measures, namely the different design of the opening diameter in the individual layers.
  • the tubesheet is five-layered, wherein the three middle layers consist of stainless steel plates.
  • An outer layer is made of a corrosion-resistant material, whereas the other outer layer consists of a pressure plate.
  • a stop is formed by provid- ing a smaller opening diameter. In this way, a particularly stable and resistant to the kinetic and thermal loads tube sheet is obtained, the corrosion resistant and at the same time provides a stop for a constant insertion depth of the tubes.
  • the tube plate according to the invention is advantageously used in Nachschaltebenleyern, where used glass tubes. These tubes are particularly susceptible to damage when material stresses in the tube sheet.
  • FIG. 1 shows the exploded view of a tube plate 100, which is constructed five-layered.
  • the individual layers 11, 12, 13, 15, 16 of the tubesheet 100 each have thirty-two circular openings 20, which are arranged in four columns and eight rows each next to and below each other. The distances between the individual openings 20 are substantially constant.
  • the individual openings 20 of the different layers or layers 11, 12, 13, 15, 16 of the tube plate 100 are formed corresponding to each other and form receiving openings 20 a (see Fig. 2 ). All layers or plates 11, 12, 13, 15, 16 have a rectangular basic shape and have approximately the same external dimensions, wherein the length and width of the layer 16 are slightly smaller than those of the layers 11, 12, 13, 15th

  • the tube plate and thus the entire heat exchanger (not shown here) to other components of a heating system (not shown here) are attached. Likewise, this can be done attachment to the heat exchanger housing (not shown here).
  • the tube bottom center plate 11 and the two adjacent plates are all made of stainless steel.
  • the plate 15 is a corrosion protection plate and is made of Teflon®.
  • the plate 15 is on the installation of the tube plate 100 in a heat exchanger (not shown here) on the exhaust side, ie the tubes (not shown here) facing to arrange.
  • the other outer plate 16 is a pressure plate made of sheet steel.
  • Eight countersunk rivets 18 can be inserted through openings 23 provided in the tubesheet 13 and can be guided through further openings 23 in the plate 16 provided for this purpose. They are dimensioned so that they stand over the tube plate 100 addition.
