Definitions

the invention also relates to a use of this steam generating plant.
Steam generating plants of the type described above are known from the prior art, for example from the international application WO 2011/104328 A2 , known.
the steam generator is arranged as a horizontally arranged, cylindrical Tube bundle heat exchanger formed.
Such a shell-and-tube heat exchanger and its use for cooling hot synthesis gas is described, for example, by the European patent specification EP 2312252 B1 ,
the hot gas is passed through the heating tubes of the tube bundle, the water to be evaporated is located in the shell space.
the steam generator can be a, often also designed as a shell-and-tube heat exchanger, preheater, from the perspective of the heat transfer medium, downstream and upstream of a superheater.
Above the steam generator is a so-called steam drum, often also horizontally arranged pressure vessel installed. Steam drum and steam generator are connected by riser and downpipes. Thereby, the water / steam mixture can be circulated, whereby the steam can be well discharged from the steam generator and a more effective heat transfer to the surface of the heating tubes of the steam generator is possible. If the steam drum can be placed at a sufficient distance above the steam generator, this circulation can function as natural circulation. If there is not enough space available, pumps must support circulation. One then speaks of forced circulation.
the side-mounted nozzles for the downpipes also induce forces on the shell of the steam generator, namely static forces due to its own weight the downpipes and by thermal expansion forces, as well as dynamic forces due to wind and earthquake loads.
forces on the shell of the steam generator namely static forces due to its own weight the downpipes and by thermal expansion forces, as well as dynamic forces due to wind and earthquake loads.
significantly higher wall thicknesses of the nozzle and the pressure jacket may be required, especially in a special form of construction of such systems, in which the weight of the steam drum is removed via the drop and risers.
the steam generating plant according to the invention makes it possible to position the steam generator near the ground, since the downpipes no longer the lowest point of the system form. This simplifies the design of upstream and downstream equipment.
the space required for the installation of the steam generating plant according to the invention is reduced compared to a corresponding system according to the prior art, since no laterally extending downpipes longer exist, but they are guided in the interior of the device down.
a preferred embodiment of the invention is characterized in that the steam generator and the steam drum are arranged to each other and the riser and the downpipe are designed so 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 installation of 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 to support the water circulation between the water jacket of the steam generator and the steam drum. In this case, even if there is no room for a sufficient distance between the steam drum and the steam generator, sufficient water circulation in the steam generator can be achieved.
a further preferred embodiment of the invention is characterized in that the steam generator and the steam drum are formed as horizontally arranged, cylindrical pressure vessel.
the cylindrical shape, with corresponding arched bottoms, has long been proven in apparatus construction and inexpensive to produce.
the horizontal arrangement allows a low height and thus good accessibility of the system.
a further preferred embodiment of the invention is characterized in that the riser and the down pipe / s integrate in the 0 o'clock position in the water jacket of the steam generator and in the 6 o'clock position in the steam drum jacket.
the lines can also be used as structural elements for supporting the steam drum.
a further preferred embodiment of the invention is characterized in that the steam generator is designed as a tube bundle evaporator. This design has long been proven in apparatus construction and inexpensive to produce.
a further preferred embodiment of the invention is characterized in that the downpipe inside the steam generator is guided around the heating pipe or tubes up to the volume area of the steam generator below it. In this way, the construction of the heating pipes is hardly affected by the downpipes and complex design measures in this area are not required.
a further preferred embodiment of the invention is characterized in that the downpipe is guided inside the steam generator through the tube bundle of the heating tubes. In this way, the or the downpipes can run straight, whereby the flow resistance in the tube is kept low.
the invention also relates to the use of a steam generating plant according to the invention, which consists in that the steam boiler is connected downstream of a steam reforming reactor and emerging from the steam reforming reactor Synthesis gas is used as a heat transfer medium in the steam generator of the steam generating plant.
the steam reforming of hydrocarbons to synthesis gas in many cases catalytically assisted carried out in a tubular reactor, takes place under high energy consumption and at high temperatures.
the resulting synthesis gas leaves the reactor at a temperature of over 800 ° C.
the synthesis gas is used as a heat transfer medium for Betreibeh a steam generating plant according to the invention.
Fig. 1 Shown in Fig. 1 is the steam generating plant 1, comprising as main components the steam generator 2 and the steam drum 3.
the steam generator 2 is designed as a tube bundle evaporator and placed horizontally.
the hot synthesis gas 4 coming from a steam reforming reactor, not illustrated, is introduced into the inlet chamber 5 of the steam generator 2, where it is blown onto the tubes 6 of the steam generator 2 Distributed tube bundle 13, continues to flow into the outlet chamber 7 and leaves the steam generator 2 for further, not shown treatment or recovery.
the steam drum 3 is arranged above the steam generator 2. In it, the boiler feed water 8 to be evaporated is fed. About the risers 9 and the downpipes 10 takes place, as natural circulation, a circulation of the water to be evaporated. The thereby reaching via the risers 9 in the steam drum 3 steam-water mixture is separated there, the steam 11 is discharged for further use and the water is returned via the downpipes 10 in the steam generator.
the downcomers enter the shell 12 of the steam generator 2 at the 0 o'clock position and then run, within the shell 12, past the heating tubes of the tube bundle 6, into the lower volume region of the shell 12.
the downcomers end as low as possible in the mantle to avoid that vapor bubbles fall into the downpipe and by as large a static height, ie To achieve the greatest possible vertical distance between the lower and the upper end of the downpipe, thereby supporting the natural circulation.
Fig. 2 shows a cross section through a steam generating plant with a course of the downpipes 10 'according to the prior art. To increase the clarity, the risers were not depicted, but they are again, as in the Fig. 1 shown example, in the 0 o'clock position of the shell 12 is arranged.
the downpipes 10 ' are connected to the steam drum 3 at the 4 o'clock and 8 o'clock positions, extend around the outside of the steam generator 2 and also open at the 4 o'clock and 8 o'clock positions in the steam generator casing 12.
Fig. 3a The downpipe 10 is connected in the 6 o'clock position to the steam drum 3 and occurs in the 0 o'clock position through the jacket 12 of the steam generator 2. Within the shell 12 extends the downpipe 10 around the tube bundle 13 around into the volume area below the water jacket 12th
Fig. 3b also shows a cross section through a steam generating plant according to the invention course of the downpipe 10.
the downpipe 10 is also connected in the 6 o'clock position to the steam drum 3 and occurs in the 0 o'clock position through the jacket 12 of the steam generator 2. Within the shell 12th the downpipe 10 extends through the tube bundle 13 into the volume region of the water jacket 12 below.
the invention offers the possibility to run a steam generating plant cheaper and more space-saving, with the installation of the system with respect to the upstream and downstream equipment is more flexible feasible.
