Definitions

  • Steam generating systems of the type described at the beginning are from the prior art, for example from the international application WO 2011/104328 A2 , known.
  • the steam generator is a horizontally arranged, cylindrical tube bundle heat exchanger educated.
  • Such a tube bundle heat exchanger and its use for cooling hot synthesis gas is described, for example, in the European patent EP 2312252 B1 .
  • the DE patent specification DE 571 207 C describes a device for increasing the water circulation in evaporators or steam boilers by means of vertical riser pipes reaching up to just above or just below the water level, characterized in that these riser pipes end in a water separator arranged above the steam chamber, which at its lowest point enters the water chamber of the The drain pipe leading to the boiler is so wide that a water level cannot form in the associated separator.
  • the hot gas is passed through the heating tubes of the tube bundle, the water to be evaporated is located in the shell space.
  • a preheater often also designed as a tube bundle heat exchanger, can be connected downstream of the steam generator, and a superheater can be connected upstream.
  • a so-called steam drum often also arranged horizontally, is installed above the steam generator.
  • the steam drum and steam generator are connected to one another by risers and downpipes.
  • the water / steam mixture can be moved in circulation, so that the steam can be led out of the steam generator and a more effective heat transfer on the surface of the heating pipes of the steam generator is possible.
  • the steam drum can be placed with sufficient distance above the steam generator, this circulation can function as a natural circulation. If there is not enough space for this, pumps have to support the circulation. One then speaks of forced circulation.
  • the laterally attached nozzles for the downpipes also induce forces on the jacket of the steam generator, namely static forces due to the dead weight of the downpipes and thermal expansion forces, as well as dynamic forces due to wind and earthquake loads.
  • forces on the jacket of the steam generator namely static forces due to the dead weight of the downpipes and thermal expansion forces, as well as dynamic forces due to wind and earthquake loads.
  • significantly greater wall thicknesses of the nozzle and the pressure jacket may be required, especially in the case of a special form of construction of such systems in which the weight of the steam drum is carried off via the downpipes and risers.
  • the object was therefore to propose the use of a steam generation system in which the disadvantages outlined are avoided.
  • the object is achieved by using a steam generation system according to the features of claim 1.
  • the space required for setting up the steam generation system according to the invention is reduced compared to a corresponding system according to the prior art, since there are no longer any laterally extending downpipes, but these are led down inside the device.
  • a preferred embodiment of the invention is characterized in that, when used according to the invention, the steam generator and the steam drum are arranged in relation to one another and the riser and downpipes are designed in this way that the water to be evaporated can be moved by natural circulation between the water jacket of the steam generator and the steam drum. This eliminates the need to install pumps and the associated maintenance and repair costs, as well as investment costs.
  • An alternative embodiment of the invention is characterized in that at least one pump is installed between the water jacket of the steam generator and the steam drum in the use according to the invention to support the water circulation. In this case, even if there is no space for a sufficient distance between the steam drum and the steam generator, sufficient water circulation can be achieved in the steam generator.
  • Another preferred embodiment of the invention is characterized by the fact that, when used according to the invention, the steam generator and the steam drum are designed as horizontally arranged, cylindrical pressure vessels.
  • the cylindrical shape, with corresponding arched bottoms, has been tried and tested in apparatus engineering for a long time and can be manufactured inexpensively.
  • the horizontal arrangement enables a low overall height and thus good accessibility to the system.
  • Another preferred embodiment of the invention is characterized in that, when used according to the invention, the riser and downpipe (s) tie into the water jacket of the steam generator in the 0 o'clock position and in the steam drum jacket in the 6 o'clock position.
  • the lines can also be used as structural elements for supporting the steam drum.
  • Another preferred embodiment of the invention is characterized in that, when the steam generator is used according to the invention, it is designed as a tube bundle evaporator. This type of construction has long been tried and tested in apparatus engineering and can be manufactured inexpensively.
  • Another preferred embodiment of the invention is characterized in that, when used according to the invention, the downpipe is routed inside the steam generator around the heating pipe (s) to the volume area of the steam generator located below. In this way, the construction of the heating pipes is hardly influenced by the downpipes and complex structural measures are not required in this area.
  • Another preferred embodiment of the invention is characterized in that, when used according to the invention, the downpipe is passed inside the steam generator through the tube bundle of the heating tubes. In this way, the downpipe (s) can run straight, whereby the flow resistance in the pipe is kept low.
  • Fig. 1 Shown in Fig. 1 is the steam generation system 1, comprising the steam generator 2 and the steam drum 3 as main components.
  • the steam generator 2 is designed as a tube bundle evaporator and is set up horizontally.
  • the hot synthesis gas 4 coming from a steam reforming reactor (not shown) is introduced into the inlet chamber 5 of the steam generator 2, is there distributed over the tubes 6 of the tube bundle 13, flows on into the outlet chamber 7 and does not leave the steam generator 2 for another treatment or recovery depicted.
  • the steam drum 3 is arranged above the steam generator 2.
  • the boiler feed water 8 to be evaporated is fed into it.
  • the water to be evaporated is circulated via the risers 9 and the downpipes 10 as a natural circulation.
  • the steam-water mixture entering the steam drum 3 via the risers 9 is separated there, the steam 11 is discharged for further use and the water is returned to the steam generator via the downpipes 10.
  • the downpipes enter the jacket 12 of the steam generator 2 in the 0 o'clock position and then run inside the jacket 12 past the heating pipes of the tube bundle 6 to the lower volume area of the jacket 12.
  • the downpipes end as deep as possible in the jacket to prevent vapor bubbles from getting into the downpipe and in order to achieve the greatest possible static height, ie the greatest possible vertical distance between the lower and the upper end of the downpipe, and thereby support the natural circulation.
  • Fig. 2 shows a cross section through a steam generation plant with a course of the downpipes 10 'according to the prior art.
  • the risers have not been illustrated, but they are again, as in the one in Fig. 1 shown example, arranged in the 0 o'clock position of the jacket 12.
  • the downpipes 10 ′ are connected to the steam drum 3 in the 4 o'clock and 8 o'clock positions, run around the outside of the steam generator 2 and also open into the steam generator jacket 12 in the 4 o'clock and 8 o'clock positions.
  • Fig. 3a shows a cross-section through a steam generation plant 1 with the downpipe 10 according to the invention.
  • the downpipe 10 is connected to the steam drum 3 in the 6 o'clock position and passes through the jacket 12 of the steam generator 2 in the 0 o'clock position the downpipe 10 around the tube bundle 13 into the volume area of the water jacket 12 located below.
  • Figure 3b also shows a cross section through a steam generation plant with the downpipe 10 according to the invention.
  • the downpipe 10 is also connected to the steam drum 3 in the 6 o'clock position and passes through the jacket 12 of the steam generator 2 in the 0 o'clock position the downpipe 10 runs through the tube bundle 13 into the volume area of the water jacket 12 located below.
  • the invention offers the possibility of using a steam generation system in a more cost-effective and space-saving manner, the installation of the system also being more flexible with regard to the upstream and downstream apparatus.
