  • the gasification reactor 30 and the channel 10 are removed, thereby clearing the way for lifting the inner throttle cable 1.
  • This is then suspended from the hoist 18, after which the detachable support elements 15 are removed and the connections to the water pipes 13 (flange 13 ') and to the steam pipes 14 (flange 14') are released.
  • the inner throttle cable 1 can now be lifted out of the gas cooler through the pipe socket 6 and transported to a work station. Both the accelerator cable 1 and the interior of the second accelerator cable 2 are now easily accessible. The fact that the distributor 11 and the collector 12 with the inner throttle cable 1 are transported together, the throttle cable 1 can be tested for pressure and tightness before reinstallation.
  • the outer gas cable 2 can be completely or partially - after sanding the weld seams 17 between its walls - disassembled into individual walls which are then lifted out of the pressure vessel 3 with the aid of the lifting device 18 and transported to a work station.

  • the described embodiment of the gas cooler is preferred in practice because of its characteristic gas flow, because this results in advantageous conditions for separating the contaminants carried by the gas.
  • the vertical tie rods 8 of the inner throttle cable 1 not only result in considerably smaller mechanical stresses within the gas cooler, but also a problem-free centering of the inner throttle cable 1, which considerably simplifies its installation and removal.

  • the wall tubes 5, 5 'bent radially in the direction of the interior of the throttle cable perform an important function, since relatively large deformations - as a result of thermal expansion and / or earthquakes, for example - can occur. In particular, blows are better absorbed during overhaul or assembly work.
  • the gas cooler is designed for relatively high outlet temperatures from the second gas passage connector, it may be advantageous to close the upper end of the annular space between the inner gas cable 1 and the outer gas cable 2 with a detachable cover and to equalize the pressure with the inside of the pressure vessel 3 to realize in other ways, for example by connecting the interior of the pressure vessel 3 with the cool part of a downstream second gas cooler and - along a cooling section - with the synthesis gas inlet, wherein a throttle body interrupts the connection to the second gas cooler in normal operation.

Description

Die Erfindung betrifft einen Gaskühler mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a gas cooler with the features of the preamble of claim 1.

Aus der FR-OS 2 513 741 ist ein solcher Gaskühler bekannt, bei dem der gasführende Kanal als mit dem Rohrstutzen fest verbundene Auskleidung aus feuerfestem Material ausgebildet ist. Der lichte Querschnitt des so gebildeten Gaseintritts als auch der Durchmesser des Rohrstutzens sind so klein, dass eine Demontage des inneren Gaszuges durch den Gaseintritt oder den Rohrstutzen hindurch nicht möglich ist. Bei Kühlern der eingangs genannten Art tritt das mit festen Verunreinigungen beladene Synthesegas mit einer Temperatur von z.B. 1500° C und einem Druck von etwa 40 bar oben in den Kühler ein und verlässt ihn beispielsweise mit ca. 700° C. Die Gaszüge sind deshalb beachtlicher Korrosion ausgesetzt. Infolge Verschmutzung treten an den Gaszügen häufig erhebliche lokale Temperaturdifferenzen und daher Wärmespannungen auf, die die Gaszüge noch zusätzlich belasten. Aus diesen Gründen sind häufig Inspektions- und Reinigungsarbeiten notwendig. Gelegentlich ist auch mit grösseren Ueberholungsarbeiten zu rechnen. Besonders betroffen ist dabei der innere Gaszug, weil auf ihn die höchsten Temperaturen einwirken und das Synthesegas ihn beidseitig beaufschlagt.Such a gas cooler is known from FR-OS 2 513 741, in which the gas-carrying duct is designed as a lining made of refractory material which is firmly connected to the pipe socket. The clear cross section of the gas inlet formed in this way and the diameter of the pipe socket are so small that it is not possible to disassemble the inner gas duct through the gas inlet or the pipe socket. In coolers of the type mentioned at the beginning, the synthesis gas loaded with solid impurities occurs at a temperature of e.g. 1500 ° C and a pressure of about 40 bar at the top of the cooler and leaves it at about 700 ° C, for example. The throttle cables are therefore exposed to considerable corrosion. As a result of pollution, considerable local temperature differences and therefore thermal stresses often occur on the gas flues, which place additional stress on the gas flues. For these reasons, inspection and cleaning work is often necessary. Occasionally, major overhaul work can also be expected. The inner gas flue is particularly affected because it is affected by the highest temperatures and the synthesis gas acts on it on both sides.

Aus der EP-OS 88 221 ist ein Gaskühler für Synthesegas bekannt, bei dem im Druckbehälter nur ein Gaszug vorgesehen ist, in dem als zusätzliche Heizflächen aus gebogenen Rohren gebildete Schottenheizwände angeordnet sind. Zum Herausnehmen der Heizflächen aus dem Druckbehälter ist dessen Deckel abnehmbar mit dem unteren Behälterteil verbunden.From EP-OS 88 221 a gas cooler for synthesis gas is known, in which only one gas flue in the pressure vessel is provided in which bulkhead heating walls formed from curved tubes are arranged as additional heating surfaces. To remove the heating surfaces from the pressure vessel, its cover is removably connected to the lower part of the vessel.

Der Erfindung liegt die Aufgabe zugrunde, einen Gaskühler der eingangs genannten Gattung so zu verbessern, dass an den Gaszügen Inspektions-, Reinigungs- und Reparaturarbeiten auf einfache und kostengünstige Weise ausgeführt werden können, ohne wesentliche Mehrkosten für seine Herstellung.The invention has for its object to improve a gas cooler of the type mentioned in such a way that inspection, cleaning and repair work can be carried out on the gas cables in a simple and inexpensive manner, without significant additional costs for its production.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des Kennzeichens des Anspruchs 1 gelöst. Beim Gaskühler nach der Erfindung lässt sich - ohne dass der Druckbehälter teilbar ausgebildet werden müsste - der innere Gaszug unabhängig vom äusseren Gaszug auf einfache Weise aus dem Druckbehälter durch den Rohrstutzen hindurch herausziehen, wonach eine optimale Zugänglichkeit des inneren Gaszuges und der von den heissen Gasen beaufschlagten Innenseite des äusseren Gaszuges erreicht ist.According to the invention, this object is achieved by the features of the characterizing part of claim 1. In the gas cooler according to the invention - without the pressure vessel having to be made divisible - the inner gas train can be pulled out of the pressure vessel through the pipe socket independently of the outer gas train, after which an optimal accessibility of the inner gas train and those exposed to the hot gases Inside of the outer throttle cable is reached.

Eine Zugänglichkeit auch der Aussenseite des äusseren Gaszuges wird nach dem Anspruch 2 dadurch erreicht, dass die einzelnen Teile dieses Gaszuges durch den Rohrstutzen hindurch herausgehoben werden. Es hat sich gezeigt, dass bei den üblichen Grössen des erfindungsgemässen Gaskühlers, der innere Gaszug und die einzelnen, den äusseren Gaszug bildenden Teile so ausgelegt werden können, dass sie je ein Gewicht von ca. 25t aufweisen; ein Gewicht also, das mit den bei jeder Anlage dieser Art ohnehin vorhandenen Hebezeugen zu bewältigen ist.Accessibility to the outside of the outer throttle cable is achieved according to claim 2 in that the individual parts of this gas cable are lifted out through the pipe socket. It has been shown that with the usual sizes of the gas cooler according to the invention, the inner gas train and the individual parts forming the outer gas train can be designed such that they each have a weight of approximately 25 tons; a weight that can be managed with the lifting devices that are already present in every system of this type.

Ein besonderer Vorteil der Erfindung ist, dass die Reihenfolge, in der die Gaszüge zugänglich gemacht werden, mit dem tatsächlichen Bedürfnis übereinstimmt: der am stärksten beanspruchte und daher am häufigsten reinigungs- und überholungsbedürftige innere Gaszug ist am leichtesten zugänglich, das Innere des äusseren Gaszuges weist den zweiten Rang an Zugänglichkeit auf, und die am wenigsten beanspruchte äussere Seite des äusseren Gaszuges wie auch die innere Seite des Druckbehälters, werden zuletzt zugänglich.A particular advantage of the invention is that the order in which the accelerator cables are made available corresponds to the actual need: the most heavily used and therefore most frequently in need of cleaning and overhaul is the most easily accessible internal gas cable, which shows the inside of the outer gas cable second in terms of accessibility, and the least stressed outer side of the outer throttle cable, as well as the inner side of the pressure vessel, are finally accessible.

Die Erfindung weist ferner den zusätzlichen Vorteil auf, dass bei Herausnahme des inneren Gaszuges aus dem Druckbehälter seine Kollektoren mitgenommen werden, so dass ev. nötige Druck- und Dichtheitsprüfungen auch ausserhalb des Druckbehälters stattfinden können. In der Ausführung gemäss Anspruch 3 ist dies auch in Bezug auf den äusseren Gaszug der Fall.The invention also has the additional advantage that when the inner throttle cable is removed from the pressure vessel, its collectors are taken along, so that any necessary pressure and tightness tests can also take place outside the pressure vessel. In the embodiment according to claim 3, this is also the case with respect to the outer throttle cable.

Das gute thermodynamische und strömungstechnische Verhalten des erfindungsgemässen Gaskühlers bleiben erhalten.The good thermodynamic and fluidic behavior of the gas cooler according to the invention are retained.

Der Gaskühler für Synthesegas weist einen prismatischen, vertikalen inneren Gaszug 1 und einen ebenfalls prismatischen, vertikalen äusseren Gaszug 2 auf, die in einem kreiszylindrischen, vertikalen Druckbehälter 3 koaxial angeordnet sind. Die Gaszüge 1 und 2 sind aus geraden, in Längsrichtung der Gaszüge verlaufenden, miteinander mittels Stegen 4 gasdicht verschweissten und wasser- bzw. dampfdurchströmten Wandrohren 5 bzw. 5' gebildet. Am oberen Ende des Druckbehälters ist ein Rohrstutzen 6 koaxial mit den Gaszügen 1 und 2 angebracht. Im oberen Bereich des Druckbehälters ist ferner ein horizontaler Gasaustrittsstutzen 7 vorhanden, der den Druckbehälter 3 durchstösst und in den Ringraum zwischen den beiden Gaszügen 1,2 mündet. Der innere Gaszug 1 mündet an seinem unteren Ende in den Ringraum. Der innere Gaszug 1 und der äussere Gaszug 2 weisen je einen regelmässigen, achteckigen, durch acht Wände begrenzten Querschnitt auf und sind gegeneinander um 22,5° verdreht angeordnet, damit im Ringraum zwischen den beiden Gaszügen 1 und 2 für Inspektionszwecke die grösstmöglichste Querschnittsfläche verfügbar ist. Die Wandrohre 5 jeweils einer Wand des inneren Gaszuges 1 münden unten in einen inneren Verteiler (Eintrittskollektor) 11, der über eine horizontale, den Druckbehälter 3 und den äusseren Gaszug 2 durchstossende erste Wasserleitung 13 mit Wasser gespiesen wird. An ihrem oberen Ende weisen die Wandrohre 5 des inneren Gaszuges 1 je eine sich nach innen radial erstreckende, Verformungen aufnehmende C-förmige Biegung auf und münden in acht innere Sammler (Austrittskollektoren) 12; einer für jede Wand. Jeder Sammler 12 ist über eine den Druckbehälter 3 durchstossende, erste Dampfleitung 14 mit einem nicht gezeigten Dampfverbraucher verbunden. Im Bereich ihres unteren Endes bilden die Wandrohre 5' des äusseren Gaszuges 2 einen Trichter, den sie unten radial, entlang einer horizontalen Ebene, verlassen, und münden in acht, einer für jede Wand, äussere Verteiler (Eintrittskollektoren) 21. Infolge dieser Formgebung können Verformungen auf günstige Weise aufgenommen werden. Jeder äussere Verteiler 21 wird über eine horizontale, den Druckbehälter durchstossende, zweite Wasserleitung 23 mit Wasser gespiesen. An ihren oberen Enden münden die Wandrohre 5' des äusseren Gaszuges 2 in acht, ebenfalls einer je Wand, Sammler (Austrittskollektoren) 22, von denen jeder über eine den Druckbehälter 3 durchstossende zweite Dampfleitung 24, wie der innere Sammler 12, mit einem nicht gezeigten Dampfverbraucher verbunden ist.The gas cooler for synthesis gas has a prismatic, vertical inner gas duct 1 and a likewise prismatic, vertical outer gas duct 2, which are arranged coaxially in a circular cylindrical, vertical pressure vessel 3. The gas passages 1 and 2 are formed from straight wall pipes 5 and 5 'running in the longitudinal direction of the gas passages, welded to one another in a gas-tight manner by means of webs 4 and through which water or steam flows. At the upper end of the pressure vessel, a pipe socket 6 is attached coaxially with the gas cables 1 and 2. In the upper area of the pressure vessel there is also a horizontal gas outlet connection 7 which penetrates the pressure vessel 3 and opens into the annular space between the two gas ducts 1, 2. The inner throttle cable 1 opens into the annular space at its lower end. The inner throttle cable 1 and the outer throttle cable 2 each have a regular, octagonal cross-section delimited by eight walls and are rotated by 22.5 ° to each other so that the largest possible cross-sectional area is available in the annulus between the two gas cables 1 and 2 for inspection purposes . The wall pipes 5 each of a wall of the inner gas duct 1 open at the bottom into an inner distributor (inlet collector) 11 which is supplied with water via a horizontal first water line 13 which penetrates the pressure vessel 3 and the outer gas duct 2. At their upper end, the wall tubes 5 of the inner throttle cable 1 each have an inward radial direction extending, deformation-absorbing C-shaped bend and open into eight inner collectors (outlet collectors) 12; one for each wall. Each collector 12 is connected to a steam consumer (not shown) via a first steam line 14 penetrating the pressure vessel 3. In the area of its lower end, the wall pipes 5 'of the outer throttle cable 2 form a funnel, which they leave radially at the bottom, along a horizontal plane, and open into eight, one for each wall, outer manifolds (inlet collectors) 21. As a result of this shape Deformations are absorbed in a favorable manner. Each outer distributor 21 is supplied with water via a horizontal, second water pipe 23 which pierces the pressure vessel. At their upper ends, the wall pipes 5 'of the outer throttle cable 2 open into eight collectors (outlet collectors) 22, likewise one per wall, each of which via a second steam line 24, like the inner collector 12, penetrating the pressure vessel 3, with one not shown Steam consumer is connected.

Wie aus der Fig. 3 ersichtlich, sind der innere Gaszug 1 und der äussere Gaszug 2 am Druckbehälter 3 mittels Zugankern 8 bzw. 8' voneinander unabhängig aufgehängt. Die Zuganker 8 des inneren Gaszuges 1 sind je an einem lösbaren Tragelement 15 befestigt, das mittels in Fig. 3 nicht gezeigter horizontaler Schrauben mit einem an der Wand des Druckbehälters 3 und am Rohrstutzen 6 angeschweissten Träger 15' verbunden ist. Jeder Zuganker 8' des äusseren Gaszuges 2 ist dagegen mit einem an der Wand des Druckbehälters 3 direkt angeschweissten Tragelement 25 verbunden. Einstellmuttern 16 ermöglichen ein einfaches Einstellen der Zuganker 8,8' an den Tragelementen 15 bzw. 25.As can be seen from FIG. 3, the inner gas cable 1 and the outer gas cable 2 are suspended independently of one another on the pressure vessel 3 by means of tie rods 8 and 8 '. The tie rods 8 of the inner throttle cable 1 are each fastened to a detachable support element 15, which is connected by means of horizontal screws (not shown in FIG. 3) to a support 15 'welded to the wall of the pressure vessel 3 and to the pipe socket 6. In contrast, each tie rod 8 'of the outer throttle cable 2 is connected to a support element 25 welded directly onto the wall of the pressure vessel 3. Adjusting nuts 16 allow simple adjustment of the tie rods 8, 8 'on the support elements 15 or 25.

In Fig. 1 und 2 ist die grösste horizontale Ausdehnung des inneren Gaszuges 1 mit d₁ bezeichnet. Beim äusseren Gaszug 2 ist die kleinste, im Innern seines oberen Bereiches messbare horizontale Ausdehnung der Abstand zwischen zwei parallelen Sammlern 22, der in Fig. 1 mit d₂ bezeichnet ist. In Fig. 1 ist noch der innere Durchmesser des Rohrstutzens 6 mit d₃ bezeichnet. Sowohl d₂ als auch d₃ sind grösser als d₁ gewählt, so dass der innere Gaszug 1 mittels eines in Fig. 1 nur symbolisch gezeigten Hebezeugs 18 ohne weiteres aus dem Gaskühler herausgehoben werden kann.In Fig. 1 and 2, the largest horizontal extent of the inner throttle cable 1 is designated d₁. In the outer throttle cable 2, the smallest, in the interior of its upper range measurable horizontal extent is the distance between two parallel headers 22, which is denoted by d₂ in Fig. 1. In Fig. 1, the inner diameter of the pipe socket 6 is denoted by d₃. Both d₂ and d₃ are chosen larger than d₁, so that the inner throttle cable 1 can easily be lifted out of the gas cooler by means of a hoist 18 shown only symbolically in FIG. 1.

Ein Vergasungsreaktor 30 ist mittels einer Flanschverbindung mit dem Rohrstutzen 6 lösbar verbunden. Das Innere des Vergasungsreaktors 30 steht über einen zum Rohrstutzen 6 koaxial angeordneten, gasführenden Kanal 10 mit dem Inneren des ersten Gaszuges 1 durchgehend in Verbindung. Der Kanal 10 hat eine hohe Wärmebeständigkeit und wärmeisolierende Wirkung und ist vorzugsweise aus einem dünnen Stahlrohr hergestellt, das mit einer dicken Isolierschicht 10' ausgekleidet ist, die zum Beispiel aus einer Stampfmasse besteht.A gasification reactor 30 is detachably connected to the pipe socket 6 by means of a flange connection. The interior of the gasification reactor 30 is in continuous communication with the interior of the first gas flue 1 via a gas-conducting channel 10 arranged coaxially with the pipe socket 6. The channel 10 has a high heat resistance and heat insulating effect and is preferably made of a thin steel tube, which is lined with a thick insulating layer 10 ', which consists for example of a ramming compound.

In seinem unteren Bereich bildet der Druckbehälter 3 ein Wasserbad 40 und ist über einen Entschlackungsstutzen 41 mit nicht gezeigten Vorrichtungen zur Behandlung von stark verschmutztem heissem Wasser verbunden. Ueber eine Wasserzufuhrleitung 42 wird Frischwasser in das Wasserbad 40 geleitet. Ein vertikales, mit den Gaszügen 1,2 koaxiales Tauchrohr 43, vorzugsweise vom äusseren Gaszug 2 getragen, erstreckt sich von diesem aus in das Wasserbad.In its lower area, the pressure vessel 3 forms a water bath 40 and is connected via a purification connection 41 to devices for the treatment of heavily soiled hot water, not shown. Fresh water is fed into the water bath 40 via a water supply line 42. A vertical dip tube 43, coaxial with the throttle cables 1, 2, preferably carried by the outer throttle cable 2, extends from the latter into the water bath.

Die acht den äusseren Gaszug 2 bildenden, vertikalen Wände sind lösbar miteinander verbunden. Die äusseren Verteiler 21 sowie die äusseren Sammler 22 sind fest mit den Wandrohren 5' des äusseren Gaszuges 2 verbunden. Es ist daher mit relativ wenig Aufwand möglich, den äusseren Gaszug 2 in acht einzelne Wände mit zugehörigem Sammler und Verteiler aufzuteilen, die aus dem Innern des Druckbehälters 3 durch den Rohrstutzen 6 hindurch herausgehoben werden können. Da die Notwendigkeit solcher Arbeiten nur ausnahmsweise entsteht, und dann nur selten für alle Wände zugleich, werden diese normalerweise mit relativ dünnen, leicht abzutragenden Schweissnähten 17 (Fig. 4) miteinander verschweisst. Es sind auch Schraubenverbindungen möglich, anstelle der Schweissnähte 17.The eight vertical walls forming the outer throttle cable 2 are detachably connected to one another. The outside Distributor 21 and the outer header 22 are firmly connected to the wall pipes 5 'of the outer throttle cable 2. It is therefore possible with relatively little effort to divide the outer throttle cable 2 into eight individual walls with associated collectors and distributors, which can be lifted out of the interior of the pressure vessel 3 through the pipe socket 6. Since the need for such work arises only exceptionally, and then only rarely for all walls at the same time, these are normally welded to one another with relatively thin, easily removable weld seams 17 (FIG. 4). Screw connections are also possible instead of the weld seams 17.

Der Gaskühler funktioniert wie folgt:
Aus dem Vergasungsreaktor 30 strömt heisses Synthesegas durch den Kanal 10 in den Innenraum des inneren Gaszuges 1. Dieser wird somit von oben nach unten durchströmt, wobei Wärme aus dem Synthesegas auf die Wandrohre 5 strahlt. Im unteren Bereich des Trichters wird das Synthesegas in das Innere des zweiten Gaszuges 2 umgelenkt und strömt jetzt von unten nach oben durch den Ringraum zwischen dem inneren Gaszug 1 und dem äusseren Gaszug 2, dabei an die Wandrohre 5 des inneren Gaszuges 1 und auch an die Wandrohre 5' des äusseren Gaszuges 2 abstrahlend. Eine wesentliche Menge der vom Synthesegas mitgeführten Verunreinigungen setzt sich während der beschriebenen Strömung ab, zum Teil auf dem Wasserbad 40 und zum Teil zuerst auf den Oberflächen der Gaszüge 1 und 2, von wo aus sie in das Bad 40 hinein fliessen.The gas cooler works as follows:
Hot synthesis gas flows out of the gasification reactor 30 through the channel 10 into the interior of the inner gas flue 1. This is thus flowed through from top to bottom, heat from the synthesis gas radiating onto the wall pipes 5. In the lower area of the funnel, the synthesis gas is diverted into the interior of the second throttle cable 2 and now flows from bottom to top through the annular space between the inner gas cable 1 and the outer gas cable 2, thereby to the wall pipes 5 of the inner gas cable 1 and also to the Radiating wall pipes 5 'of the outer throttle cable 2. A substantial amount of the impurities carried by the synthesis gas settles during the flow described, partly on the water bath 40 and partly first on the surfaces of the gas passages 1 and 2, from where they flow into the bath 40.

Speisewasser strömt durch die erste und zweite Wasserleitung 13 bzw. 23 in die Verteiler 11 bzw. 21 und von dort, vorzugsweise in Naturumlauf, durch die vertikalen Wandrohre 5 bzw. 5', bis es in Dampfform die Sammler 12 bzw. 22 erreicht. Der Dampf gelangt über die erste und zweite Dampfleitung 14 bzw. 24 zu Verbrauchern.Feed water flows through the first and second water pipes 13 and 23 into the distributors 11 and 21 and from there, preferably in natural circulation, through the vertical wall pipes 5 and 5 'until the collectors 12 and 22 reached. The steam reaches consumers via the first and second steam lines 14 and 24, respectively.

Das gekühlte Synthesegas verlässt den Gaskühler über den Gasaustrittsstutzen 7. Der oberhalb des Stutzens 7 befindliche Bereich zwischen dem innneren Gaszug 1 und dem äusseren Gaszug 2 sowie des Druckbehälters 3 sind mit stagnierendem Synthesegas gefüllt, wobei durch die Aussenwand des äusseren Gaszuges 2 hindurch etwas Wärme aus diesem abgeführt wird. Auf diese Weise entsteht innerhalb des Druckbehälters 3 ein gewisser Druckausgleich zwischen der Innen- und Aussenseite eines jeden Gaszuges, so dass diese für relativ geringe Druckdifferenzen ausgelegt werden können und lediglich der Druckbehälter 3 vom hohen Innendruck beansprucht wird.The cooled synthesis gas leaves the gas cooler via the gas outlet connection 7. The area located above the connection 7 between the inner gas train 1 and the outer gas train 2 and the pressure vessel 3 are filled with stagnant synthesis gas, with some heat being emitted through the outer wall of the outer gas train 2 this is dissipated. In this way, a certain pressure equalization occurs between the inside and outside of each throttle cable within the pressure vessel 3, so that these can be designed for relatively small pressure differences and only the pressure vessel 3 is stressed by the high internal pressure.

Aus der beschriebenen Arbeitsweise des erfindungsgemässen Gaskühlers und der Wärmeisolation 10' des Kanals 10 ergibt sich, dass die ganze Aufhängung der Gaszüge 1 und 2, insbesondere die Zuganker 8 und 8', in einer relativ kühlen Zone des Gaskühlers angeordnet ist.From the described method of operation of the gas cooler according to the invention and the thermal insulation 10 'of the duct 10, it follows that the entire suspension of the gas cables 1 and 2, in particular the tie rods 8 and 8', is arranged in a relatively cool zone of the gas cooler.

Für Reinigungs- und Reparaturarbeiten werden der Vergasungsreaktor 30 und der Kanal 10 entfernt und damit der Weg zum Herausheben des inneren Gaszuges 1 freigelegt. Dieser wird dann am Hebezeug 18 aufgehängt, wonach die lösbaren Tragelemente 15 abmontiert und die Verbindungen zu den Wasserleitungen 13 (Flansch 13') und zu den Dampfleitungen 14 (Flansch 14') gelöst werden. Der innere Gaszug 1 kann nun aus dem Gaskühler durch den Rohrstutzen 6 hindurch herausgehoben und zu einem Arbeitsplatz transportiert werden. Sowohl der Gaszug 1 als auch das Innere des zweiten Gaszuges 2 sind nun gut zugänglich. Dadurch dass die Verteiler 11 und die Sammler 12 mit dem inneren Gaszug 1 zusammen transportiert werden, kann der Gaszug 1 vor dem Wiedereinbau auf Druck und Dichtheit getestet werden.For cleaning and repair work, the gasification reactor 30 and the channel 10 are removed, thereby clearing the way for lifting the inner throttle cable 1. This is then suspended from the hoist 18, after which the detachable support elements 15 are removed and the connections to the water pipes 13 (flange 13 ') and to the steam pipes 14 (flange 14') are released. The inner throttle cable 1 can now be lifted out of the gas cooler through the pipe socket 6 and transported to a work station. Both the accelerator cable 1 and the interior of the second accelerator cable 2 are now easily accessible. The fact that the distributor 11 and the collector 12 with the inner throttle cable 1 are transported together, the throttle cable 1 can be tested for pressure and tightness before reinstallation.

Erweist es sich als notwendig, den äusseren Gaszug 2, einen Teil davon oder auch die Innenseite des Druckbehälters 3 besser zugänglich zu machen, so kann der äussere Gaszug 2 ganz oder teilweise - nach Abschmirgeln der Schweissnähte 17 zwischen seinen Wänden - in einzelne Wände zerlegt werden, die dann mit Hilfe des Hebezeuges 18 aus dem Druckbehälter 3 herausgehoben und zu einem Arbeitsplatz transportiert werden. Die mitgeführten Verteiler 21 und Sammler 22 können dann dazu verwendet werden, etwaige Druck- und Dichtheitstests vor dem Wiedereinbau durchzuführen.If it proves necessary to make the outer throttle cable 2, a part thereof or the inside of the pressure vessel 3 more accessible, the outer gas cable 2 can be completely or partially - after sanding the weld seams 17 between its walls - disassembled into individual walls which are then lifted out of the pressure vessel 3 with the aid of the lifting device 18 and transported to a work station. The distributor 21 and collector 22 carried along can then be used to carry out any pressure and tightness tests before reinstallation.

Die beschriebene Ausführungsform des Gaskühlers wird in der Praxis wegen ihrer charakteristischen Gasführung bevorzugt, weil dadurch sich vorteilhafte Bedingungen für das Abscheiden der vom Gas mitgeführten Verunreinigungen ergeben.The described embodiment of the gas cooler is preferred in practice because of its characteristic gas flow, because this results in advantageous conditions for separating the contaminants carried by the gas.

Es ist möglich, auf die lösbaren Tragelemente 15 zu verzichten und die Zuganker 8 des inneren Gaszuges 1 an quer zu deren Längsachse angeordneten und mit dem Druckbehälter 3 fest verbundenen Tragelementen zu befestigen. Durch die vertikalen Zuganker 8 des inneren Gaszuges 1 ergeben sich jedoch nicht nur erheblich kleinere mechanische Beanspruchungen innerhalb des Gaskühlers, sondern auch eine problemlose Zentrierung des inneren Gaszuges 1, die sein Ein- und Ausbauen wesentlich vereinfacht. Die Wasserleitungen 13,23 und die Dampfleitungen 14,24 sind so ausgelegt, dass sie eventuelle Pendelungstendenzen der Gaszüge 1 und 2 verhindern bzw. hemmen.It is possible to dispense with the detachable support elements 15 and to fasten the tie rods 8 of the inner throttle cable 1 to support elements arranged transversely to their longitudinal axis and firmly connected to the pressure vessel 3. The vertical tie rods 8 of the inner throttle cable 1 not only result in considerably smaller mechanical stresses within the gas cooler, but also a problem-free centering of the inner throttle cable 1, which considerably simplifies its installation and removal. The water pipes 13, 23 and the steam pipes 14, 24 are designed in such a way that they prevent or inhibit any tendency of the gas cables 1 and 2 to oscillate.

Die zur Aufnahme von Verformungen radial in Richtung auf das Innere des Gaszuges gebogenen Wandrohre 5,5' erfüllen eine wichtige Funktion, da relativ grosse Verformungen - infolge zum Beispiel von Wärmedehnungen und/oder Erdbeben - auftreten können. Insbesondere werden dadurch Schläge während Ueberholungs- bzw. Montagearbeiten besser aufgenommen.The wall tubes 5, 5 'bent radially in the direction of the interior of the throttle cable perform an important function, since relatively large deformations - as a result of thermal expansion and / or earthquakes, for example - can occur. In particular, blows are better absorbed during overhaul or assembly work.

Falls der Gaskühler für relativ hohe Austrittstemperaturen aus dem zweiten Gasdurchtrittsstutzen ausgelegt ist, kann es von Vorteil sein, das obere Ende des Ringraumes zwischen dem inneren Gaszug 1 und dem äusseren Gaszug 2 mit einem lösbaren Deckel zu schliessen und den Druckausgleich mit dem Innern des Druckbehälters 3 auf andere Wege zu verwirklichen, zum Beispiel durch Verbinden des Inneren des Druckbehälters 3 mit dem kühlen Teil eines nachgeschalteten zweiten Gaskühlers und - entlang einer Kühlstrecke - mit dem Synthesegaseintritt, wobei im Normalbetrieb ein Drosselorgan die Verbindung mit dem zweiten Gaskühler unterbricht.If the gas cooler is designed for relatively high outlet temperatures from the second gas passage connector, it may be advantageous to close the upper end of the annular space between the inner gas cable 1 and the outer gas cable 2 with a detachable cover and to equalize the pressure with the inside of the pressure vessel 3 to realize in other ways, for example by connecting the interior of the pressure vessel 3 with the cool part of a downstream second gas cooler and - along a cooling section - with the synthesis gas inlet, wherein a throttle body interrupts the connection to the second gas cooler in normal operation.

Im gleichen Ausführungsbeispiel könnten auch die lösbaren Tragelemente 15 am inneren Gaszug 1 lösbar und dafür der Zuganker 8 direkt an dem mit dem Druckbehälter 3 fest verbundenen Träger 15' befestigt sein.In the same exemplary embodiment, the detachable support elements 15 on the inner throttle cable 1 could also be detachable, and for this purpose the tie rod 8 could be fastened directly to the support 15 ′ which is firmly connected to the pressure vessel 3.
