Definitions

  • the designated with 1 porous body is formed in the particular embodiment shown in FIG. 1 as an annular cylinder body with annular top. It should be noted here that the porous body 1 in the context of the present invention may also have other shapes (square, oval, conical). It is clear that the shape chosen for the porous body 1, which forms the heart of the steam generator, can influence the whole design of the construction of the steam generator. The shape of the annular cylinder chosen for the example shown in Fig. 1 has obvious structural advantages and can therefore be considered as a preferred embodiment.
  • the porous body 1 according to a preferred embodiment of porous ceramic material of the kind as it is used for burners for example, methane gas, natural gas, fuel oil, etc.
  • a nikwringförmiger gap 6 Between the shell 2 and the shell 3 is a Vietnamese nikwringförmiger gap 6, whose function is the preheating of the medium to be evaporated. This satisfies the entire gap 6 in which it passes via the supply line 7, which feeds the medium to be evaporated by means of a suitable pump 8 and which is provided with a regulating valve 9, with which the amount of the medium to be evaporated - manually or automatically - regulated and the desired amount of steam and / or the caloric capacity of the device can be adjusted.
  • the amount of the medium to be evaporated is regulated according to the requirements, while by means of the valve 18, the composition and the temperature of the hot fluid for heating the porous body 1 is regulated in a suitable manner.
  • the output line 22 for the generated steam is connected, the steam discharge amount and thus the pressure in the gap 24 between the upper part of the porous body 1 and the lid 4 is regulated by means of a valve 23.
  • the lid 4 is also provided with a safety valve 25 which opens if the pressure in the space 24 should exceed a permissible level.
  • the steam generator according to the invention operates as follows: As already mentioned, the medium to be evaporated is sprayed through the nozzles 16 onto the input surface - in the case shown in FIG. 1, the cylindrical surface of the interior of the annular body forming the porous body 1 , but in forms of realization of various education could also be formed by differently shaped entry surfaces - the porous body 1 nebulized.
  • the temperature of the hot fluid is preferably higher than 1200 ° C, measured in its entrance zone into the porous body.
  • porous body 1 must be able to withstand such temperatures for a long time and also endure inevitable thermal overshoots (excursions) during shutdown periods of the steam generator.
  • An absolutely suitable material for this purpose is now commercially available, from which also the porous ceramic body, which are used for the burners in modern heating systems for the combustion of heating oil, methane, natural gas, etc., are used.
  • the amount of exhaust gas in relation to the amount of steam generated is very low and does not cause any special disturbances.
  • the advantage lies in the fact that practically the entire amount of energy of the exhaust gases benefits the consumer without special contamination problems occurring in the porous body 1.
  • the medium to be evaporated is pre-heated in the annular space 6 before atomization in the nozzles 16 and 19. To avoid unnecessary heat loss, the entire outer shell 3 can be suitably isolated.
  • the arrangement of the basic elements of the fast steam generator according to the invention can vary considerably within the scope of the present invention.
  • the shape, the dimensions and the porosity of the porous body 1 may vary, as well as its spatial arrangement (horizontal orientation of the axis, rotation through 180 °, position of the nozzles 16 relative to the porous body 1, etc.).
  • What counts, however, is the fundamental idea that the medium to be evaporated and the hot fluid inside a porous body 1 meet directly, whose function is ultimately only the distribution of the two media on a much larger meeting surface.
