Definitions

  • the invention relates to a device for generating water vapor by combining hydrogen and oxygen, in particular for the short-term provision of steam capacity to cover peak performance in thermal power plants, with a combustion chamber for combining hydrogen and oxygen and with a downstream injection cooler, in which the in generated in the combustion chamber, a very high temperature steam is brought by injecting feed water to the parameters suitable for feeding into the steam turbine while increasing the steam mass flow, the desuperheater being formed by a double-walled cylinder.
  • Such devices for generating water vapor are known from GB-A-463 738. With them, the fuel formed by hydrogen is blown into a combustion chamber together with oxygen as an oxidizer. Furthermore, water with the quality of feed water is injected into the steam flow, whereby on the one hand a reduction in the very high steam temperature and on the other hand an increase in the steam mass flow are achieved.
  • the present invention has for its object to provide a device of the type described in the introduction, with which it is possible in a technically simple manner to control the high temperatures of to control about 3000 ° C and to change the resulting water vapor in terms of its parameters, in particular temperature and pressure, so that the steam can be fed to a downstream steam turbine.
  • the solution to this problem by the invention is characterized in that a lining made of an axially extending tube bundle is arranged on the inner wall of the cylinder, the tubes of which are fed to the feed water at the end facing the combustion chamber, the other end of the tubes with the annular space of the is connected to double-walled cylinders, and that some tubes of the tube bundle form part of the length by radial deflections liner-free surfaces between the passing tubes, in which in the inner wall of the cylinder injectors for the feed water are arranged, to which the feed water is fed through a feed water guide cylinder, which between the inner wall and the outer wall of the double-walled cylinder are arranged in the region of the injection devices and the feed water feeds the injection devices from the end of the annular space facing away from the feed water inlet.
  • a steam generator of the generic type consisting of a combustion chamber and an injection cooler is created, which consists of simple components which can be manufactured in a conventional manner and processed with conventional technology, the high temperatures and pressures being safely controlled.
  • the entire inner wall of the double-walled cylinder is cooled intensively, in the area of the lining by the tubes, which also largely prevent heating of the inner wall by radiation, and in the area of the lining-free surfaces by the in in this area feed water exiting through the injection openings.
  • the design according to the invention thus avoids uncontrollable thermal stresses both in the stationary operating state and when starting and stopping, because thin-walled components are used and structural temperature differences within a component are avoided.
  • the device according to the invention is particularly suitable for the short-term provision of steam capacity for covering peak power in thermal power plants, which can be both conventional steam generators and nuclear power plants.
  • the injection devices are formed by radially oriented pipe sections which are arranged between the continuous pipes and the bends of the remaining pipes in the radial direction behind these pipes in the liner-free surfaces of the inner wall. These tube pieces are equipped at their outlet end with a bottom provided with outlet openings. The outlet end of the pipe sections can be chamfered.
  • the tubes of the tube bundle are made with a very small wall thickness and from a material with high thermal conductivity and a low coefficient of thermal expansion.
  • circular tubes with a diameter of 6 mm and a wall thickness of 0.3 mm are used in cross section.
  • the portion of the double-walled cylinder lying between the front end of the double-walled cylinder and the injection openings can be formed at least as part of the combustion chamber.
  • the combustion chamber used to oxidize the hydrogen in which temperatures of approximately 3000 ° C. prevail, can be at least partially made in one piece with the injection cooler.
  • the device intended for generating water vapor by combining hydrogen and oxygen comprises a double-walled cylinder 1 comprising an inner wall 2, an outer wall 3 and two end walls 4 and 5, through which an annular space 6 is formed which extends over the entire length of the double-walled cylinder 1.
  • a lining of a plurality of tubes 7 is arranged on the inner wall 2.
  • tubes 7 form a tube bundle with an axial course.
  • the tubes have a circular cross section with an outer diameter of 6 mm and a wall thickness of 0.3 mm.
  • tubes with a different cross section for example a rectangular cross section, can also be used.
  • the tubes 7 of the tube bundle 1 are supplied with feed water at the end of the cylinder formed by the end wall 4.
  • the feed water supply 8 is indicated by an arrow.
  • the other end of the pipes 7 is connected via pipe bends 9 to the end of the annular space 6 which is closed by the end wall 5.
  • the double-walled cylinder 1 is provided with an annular flange 10 for suspension or storage.
  • some tubes 7 are provided with radial bends 7a, so that there are liner-free surfaces 11 on the inner wall 2 between the tubes 7 of the tube bundle passing through (see FIG. 2).
  • every second tube 7 is provided with such a bend 7a.
  • the bends 7a are designed such that these partial lengths of the tubes 7 lie radially behind the adjacent, continuous tube 7.
  • Feed water is injected into the interior of the cylinder 1 through these outlet openings 12a.
  • the feed water is closed flows in front of the tubes 7 and the entire axial extent of the annular space 6.
  • a feed water guide cylinder 13 is arranged in the annular space 6, which extends both over the area of the pipe sections 12 and over the area of the inner wall 2 that extends between the end wall 4 and the pipe sections 12 lies.
  • the feed water guide cylinder 13 thus ensures that the feed water supplied to the annular space 6 via the pipe bends 9 reaches the region of the end wall 4 and is supplied to the pipe sections 12 coming from this end wall 4.
  • the sectional view in FIG. 1 finally reveals that in the exemplary embodiment the inner wall 2 of the cylinder 1 is also bent radially outward in the region of the bends 7a. In this way, in conjunction with the tube pieces 12, these bends 7a are guided against lateral displacements; on the other hand it is avoided that uncontrollable thermal stresses occur in the area of the lining-free surfaces 11.
  • An arrow 14 in FIG. 1 indicates that the end of the double-walled cylinder 1 which has the end wall 4 is supplied with water vapor which is formed by combining hydrogen and oxygen.
  • the inlet area of this medium which is approximately 3000 ° C., accordingly forms at least part of a combustion chamber which is cooled by feed water.
  • This feed water which is fed through the feed water supply 8 first to the pipes 7 and then to the annular space 6 for cooling, is then injected into the interior of the double-walled cylinder 1 via the outlet openings 12a of the pipe sections 12, which on the one hand causes the parameters, in particular temperature and pressure, of the hot feed water can be brought to values which allow the steam emerging from the cylinder 1 to feed downstream steam turbine; on the other hand, the steam mass flow is increased by the injected feed water, since the steam quantity supplied to the downstream steam turbine, not shown in the drawing, results from addition of the two partial quantities, which arise on the one hand by combining hydrogen and oxygen and on the other hand by evaporation of feed water.
  • the injection cooler forming at least part of the combustion chamber consists of simple components which can also be produced in a conventional manner and processed using conventional technology. All parts of the construction heated by contact or radiation from the steam at 3000 ° C are reliably cooled, while at the same time ensuring that no uncontrollable thermal stresses arise in the components, both in a stationary operating state and when starting up and shutting down. In this context, it is important that thin-walled components with the same wall thickness are used so that structure-related temperature differences within a component are also excluded.
