Abstract

A low-temperature carbonization drum for waste includes many heating tubes located in the interior. The tubes are each secured by one end to a first end plate and by the other end to a second end plate. At least one support location for supporting the heating tubes is provided between the two end plates to prevent them from sagging. Each support location is divided into at least two spaced-apart partial supports, each with one bracket configuration. Each bracket configuration includes a plurality of support brackets that are located in the same plane as one another. The support brackets are located one after another (are staggered) and are rotationally offset from one another. As a result, the solid material in the waste can be transported largely unimpeded past the support locations.

Description

Beschreibungdescription
Innenberohrte, drehbare Heiz a mer für AbfallPipe, rotatable heater for waste
Die Erfindung bezieht sich auf eine um ihre Längsrichtung drehbare Heizkammer für Festgut, insbesondere auf eine Schweltrommel für Abfall, mit einer Anzahl im Innenraum lie¬ gender Heizrohre, die jeweils mit dem einen Ende an einer er¬ sten Endplatte und mit dem anderen Ende an einer zweiten End- platte befestigt sind.The invention relates to a heating chamber for solid material which can be rotated about its longitudinal direction, in particular to a smoldering drum for waste, with a number of heating pipes located in the interior, each with one end on a first end plate and the other end on one second end plate are attached.
Die Heizkammer wird insbesondere als Schweltrommel für Abfall zum Zwecke der thermischen Abfallentsorgung eingesetzt, be¬ vorzugt nach dem Schwel-Brenn-Verfahren.The heating chamber is used in particular as a smoldering drum for waste for the purpose of thermal waste disposal, preferably according to the smoldering-burning method.
Auf dem Gebiet der Abfallbeεeitigung ist das sogenannte Schwel-Brenn-Verfahren bekannt geworden. Das Verfahren und eine danach arbeitende Anlage zur thermischen Abfallentsor¬ gung sind beispielsweise in der EP-A-0 302 310 beschrieben. Die Anlage zur thermischen Abfallentsorgung nach dem Schwel- Brenn-Verfahren enthält als wesentliche Komponenten eine Schwelkammer (Pyrolysereaktor) und eine Hochtemperatur-Brenn¬ kammer. Die Schwelkammer setzt den über eine Abfall-Trans¬ porteinrichtung aufgegebenen Abfall in Schwelgase und Pyroly- sereststoff um. Die Schwelgase und der Pyrolysereststoff wer¬ den sodann nach geeigneter Aufarbeitung dem Brenner der Hoch- teirperatur-Brennkam er zugeführt. In der Hochtemperatur- Brennkammer entsteht schmelzflüssige Schlacke, die über einen Abzug entnommen wird und die nach Abkühlung in glasartiger Form vorliegt. Das entstehende Rauchgas wird über eine Rauch¬ gasleitung einem Kamin als Auslaß zugeführt. In diese Rauch¬ gasleitung sind insbesondere ein Abhitzeerzeuger als Kühlein¬ richtung, eine Staubfilteranlage und eine Rauchgasreinigungs¬ anlage eingebaut. Eine solche Anlage hat weite Anerkennung gefunden ("Stuttgarter Zeitung" vom 18.08.1993, Artikel mit der Oberschrift "Schwel-Brenn-Verfahren bringt Recycling-Re¬ kord") . Als Schwelkammer (Pyrolysereaktor) wird in der Regel eine sich drehende, relativ lange Schweltrommel eingesetzt, die innen eine Vielzahl von parallelen Heizrohren aufweist, an denen der Abfall weitgehend unter Luftabschluß aufgeheizt wird. Die Schweltrommel dreht sich dabei um ihre Längsachse. Vorzugsweise ist die Längsachse etwas gegenüber der Horizon¬ talen geneigt, so daß sich das feste Schwelgut am Ausgang der Schweltrommel ansammeln und von dort über ein Austragsrohr ausgetragen werden kann. Beim Drehen wird der Abfall durch die Heizrohre emporgehoben und fällt wieder herab. Hierdurch und durch nachrückenden Abfall wird der Transport des Fest- guts (Staub, Brocken aus Kohlenstoff (Koks) , Steine, Fla¬ schen-, Metall-, Keramik-Teile etc.) in Richtung auf die Aus- tragsöffnung der Schweltrommel bewerkstelligt.The so-called smoldering-burning method has become known in the field of waste disposal. The method and a plant for thermal waste disposal operating according to it are described, for example, in EP-A-0 302 310. The essential components of the plant for thermal waste disposal using the smoldering process include a smoldering chamber (pyrolysis reactor) and a high-temperature combustion chamber. The smoldering chamber converts the waste fed in via a waste transport device into smoldering gases and pyrolysis residues. The carbonization gases and the pyrolysis residues are then fed to the burner of the high-temperature combustion chamber after suitable processing. Molten slag is produced in the high-temperature combustion chamber, which is removed via a fume hood and which, after cooling, is in a glass-like form. The resulting flue gas is fed to a chimney as an outlet via a flue gas line. In this flue gas line, in particular, a waste heat generator as a cooling device, a dust filter system and a flue gas cleaning system are installed. Such a plant has been widely recognized ("Stuttgarter Zeitung" from August 18, 1993, article with the headline "Smoldering process brings recycling record"). As a smoldering chamber (pyrolysis reactor), a rotating, relatively long smoldering drum is generally used, which has a large number of parallel heating pipes on the inside, on which the waste is largely heated in the absence of air. The smoldering drum rotates about its longitudinal axis. The longitudinal axis is preferably slightly inclined with respect to the horizontal, so that the solid carbonization material collects at the outlet of the carbonization drum and can be discharged from there via a discharge pipe. When turning, the waste is lifted up through the heating pipes and falls down again. As a result of this and through subsequent waste, the transport of the solid material (dust, lumps of carbon (coke), stones, bottles, metal, ceramic parts, etc.) is carried out in the direction of the discharge opening of the carbonization drum.
Es hat sich nun gezeigt, daß aus Rentabilitätsgründen, aber auch aus Gründen einer ausreichenden Pyrolyse und eines hohen Durchsatzes die Schweltrommel relativ lang gebaut sein soll- te. Das bedeutet, daß auch die im Innenraum liegenden Heiz¬ rohre eine entsprechende Länge besitzen müssen. Je nach Mate¬ rial dieser Heizrohre und ihrer Länge kann es nun vorkommen, daß diese - sofern nicht Abhilfe geschaffen wird - im Innen¬ raum durchhängen. Bei der Drehbewegung der Schweltrommel führt dies zu Wechselbelastungen, so daß die Gefahr bestehen kann, daß die Heizrohre aus ihrer endseitigen Halterung her¬ ausgerissen werden. Insbesondere bei Heizrohren, die eine Länge von 20 bis 30 Metern oder noch mehr besitzen, kann eine solche Gefahr bestehen.It has now been shown that for reasons of profitability, but also for reasons of sufficient pyrolysis and high throughput, the smoldering drum should be built relatively long. This means that the heating pipes lying in the interior must also have a corresponding length. Depending on the material of these heating tubes and their length, it can now occur that they sag in the interior, unless remedial action is taken. During the rotary movement of the smoldering drum, this leads to alternating loads, so that there can be a risk that the heating pipes will be torn out of their end holder. Such a danger can exist in particular in the case of heating pipes which are 20 to 30 meters long or even more.
Die Erfindung beruht auf der Überlegung, daß man zum Stützen der Heizrohre mindestens eine einfache Stützstelle, bevorzugt aber mindestens zwei Stützstellen im Innenraum vorsehen soll¬ te. Eine solche Stützstelle wird in Form einer Halterung oderThe invention is based on the consideration that at least one simple support point, but preferably at least two support points in the interior, should be provided for supporting the heating pipes. Such a support point is in the form of a bracket or
Rohrdurchführung ausgeführt werden können. Dies bedeutet aber unweigerlich, daß der freie Querschnitt an der Stützstelle, der für die Passage des Festguts und des Schwelgases erfor¬ derlich ist, verringert wird. Dadurch wird der Transport des Festguts und der Schwelgase - unter Umständen bedeutend - be¬ hindert.Pipe penetration can be carried out. But this inevitably means that the free cross-section at the support point, which is necessary for the passage of the solid material and the carbonization gas is reduced. As a result, the transport of the solid material and the carbonization gases - possibly significant - is prevented.
Aufgabe der Erfindung ist es daher, eine um ihre Längsrich¬ tung drehbare Heizkammer für Festgut der eingangs genannten Art so auszugestalten, daß eine Abstützung der Heizrohre ge¬ währleistet ist, ohne daß der Durchgang des Festguts und der Schwelgase nennenswert behindert wird.The object of the invention is therefore to design a heating chamber for solid material of the type mentioned that can be rotated about its longitudinal direction in such a way that the heating pipes are supported without significantly impairing the passage of the solid material and the carbonization gases.
Die genannte Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwischen den Endplatten mindestens eine Stützstelle zum Stüt¬ zen der Heizrohre vorgesehen ist, wobei an dieser Stützstelle mindestens n = 2 in Längsrichtung beabstandete Stützkonsolen vorgesehen sind, die an der Innenwand befestigt sind und je¬ weils eine unterschiedliche Gruppe der Heizrohre abstützen.According to the invention, this object is achieved in that at least one support point for supporting the heating pipes is provided between the end plates, at which support point at least n = 2 longitudinally spaced support brackets are provided, which are fastened to the inner wall and in each case one support different group of heating pipes.
Man kann dies auch so ausdrücken: In Längsrichtung der Heiz- kammer gesehen gibt es mindestens eine Stützstelle, die in mindestens zwei Teil-Stützstellen aufgeteilt ist. An jeder dieser Teil-Stützstellen ist mindestens eine Stützkonsole für eine Gruppe der Heizrohre angeordnet, und die Stützkonsolen der ersten Teil-Stützstelle sind gegenüber den Stützkonsolen der zweiten Teil-Stützstelle drehversetzt und gestaffelt (be¬ abstandet), so daß ausreichend Zwischenraum zum Transport des Festguts und der Schwelgase verbleibt.This can also be expressed as follows: seen in the longitudinal direction of the heating chamber there is at least one support point which is divided into at least two partial support points. At each of these partial support points, at least one support bracket for a group of heating pipes is arranged, and the support brackets of the first partial support point are rotationally offset and staggered (spaced) from the support brackets of the second partial support point, so that there is sufficient space for transporting the Solid matter and the smoldering gases remain.
Eine besonders bevorzugte Ausbildung der Heizkammer zeichnet sich demgemäß dadurch aus, daß jede Stützstelle unterteilt ist in p > 2 beabstandete Teil-Abstützungen mit je einem Kon¬ solen-Arrangement, wobei jedes Konsolen-Arrangement mehrere in derselben Ebene liegende Stützkonsolen umfaßt. Weitere vorteilhafte Ausgestaltungen sind in den Unteransprü- chen gekennzeichnet. Ausführungsbeispiele der Erfindung werden im folgenden anhand von 9 Figuren näher erläutert. Gleiche oder einander entspre¬ chende Bauelemente sind dabei mit denselben Bezugszeichen versehen. Es zeigen:A particularly preferred embodiment of the heating chamber is accordingly characterized in that each support point is subdivided into p> 2 spaced partial supports, each with a console arrangement, each console arrangement comprising a plurality of support consoles lying in the same plane. Further advantageous refinements are characterized in the subclaims. Embodiments of the invention are explained in more detail below with reference to 9 figures.

Nach Figur 1 wird fester Abfall A über eine Zufuhr- oder Auf¬ gabeeinrichtung 2 und eine Schnecke 4, die von einem Motor 6 angetrieben wird und in einem Aufgaberohr 7 angeordnet ist, zentral in einen Pyrolysereaktor oder eine Schwelkammer 8 eingebracht. Die Schwelkammer 8 ist im Ausführungsbeispiel eine innenbeheizbare, um ihre Längsachse 10 drehbare Schwel¬ oder Pyrolysetrommel, die eine Länge von 15 bis 30 m besitzen kann, die bei 300 bis 600 °C arbeitet, die weitgehend unter Sauerstoffabschluß betrieben wird und die neben flüchtigem Schwelgas s einen weitgehend festen Pyrolysereststoff f er¬ zeugt. Es handelt sich dabei um eine innenberohrte Schwel¬ trommel 8 mit einer Vielzahl (z. B. 50 bis 200) von parallel zueinander ausgerichteten Heizrohren 12, von denen in Figur 1 nur vier gezeigt sind, die im Innenraum 13 angeordnet sind. Am rechten oder "heißen" Ende ist ein Einlaß für Heizgas h in Form einer ruhenden, abgedichteten Heizgas-Einlaßkammer 14 vorgesehen, und am linken oder "kalten" Ende ist ein Auslaß für das Heizgas h in Form einer ruhenden, abgedichteten Heiz¬ gas-Auslaßkammer 16 angeordnet. Die Längsachse 10 der Schwel- trommel 8 ist bevorzugt gegenüber der Horizontalen geneigt, so daß der Auslaß am rechts gelegenen "heißen" Ende tiefer liegt als der links gezeigte Einlaß für den Abfall A.Figure 9 shows a heating tube attachment in a support bracket. According to FIG. 1, solid waste A is introduced centrally into a pyrolysis reactor or a smoldering chamber 8 via a feed or feed device 2 and a screw 4, which is driven by a motor 6 and is arranged in a feed tube 7. In the exemplary embodiment, the smoldering chamber 8 is an internally heatable smoldering or pyrolysis drum which can be rotated about its longitudinal axis 10 and which can have a length of 15 to 30 m, which operates at 300 to 600 ° C., which is operated largely with the exclusion of oxygen and which, in addition to volatile smoldering gas s produces a largely solid pyrolysis residue. This is an inner-tube carbonization drum 8 with a multiplicity (for example 50 to 200) of heating tubes 12 aligned parallel to one another, of which only four are shown in FIG. 1 and are arranged in the interior 13. At the right or "hot" end there is an inlet for heating gas h in the form of a resting, sealed heating gas inlet chamber 14, and at the left or "cold" end there is an outlet for the heating gas h in the form of a resting, sealed heating gas inlet. Outlet chamber 16 arranged. The longitudinal axis 10 of the smoldering drum 8 is preferably inclined with respect to the horizontal, so that the outlet at the "hot" end on the right is lower than the inlet for waste A shown on the left.
Der Pyrolysetrommel 8 ist ausgangs- oder austragsseitig über ein sich mitdrehendes zentrales Austragsrohr 17 eine Aus- tragsvorrichtung 18 nachgeschaltet, die mit einem Schwelgas- Abzugsstutzen 20 für den Abgang des Schwelgases s und mit ei¬ nem Pyrolysereststoffausgang 22 für die Abgabe des festen Py¬ rolysereststoffes f versehen ist. Eine an den Schwelgas-Ab- zugsstutzen 20 angeschlossene Schwelgasleitung kann mit dem Brenner einer Hochtemperatur-Brennkammer verbunden sein.A discharge device 18 is connected downstream of the pyrolysis drum 8 on the output or discharge side via a rotating central discharge tube 17, said discharge device being provided with a carbonization gas discharge nozzle 20 for the discharge of the carbonization gas and with a pyrolysis residue outlet 22 for the discharge of the solid pyrolyzation residue f is provided. A carbonization line connected to the carbonization gas outlet 20 can be connected to the burner of a high-temperature combustion chamber.
Die Drehbewegung der Schweltrommel 8 um ihre Längsachse 10 wird durch einen Antrieb 24 in Form eines Getriebes bewirkt, der an einen Motor 26 angeschlossen ist. Die Antriebsmittel 24, 26 arbeiten zum Beispiel auf einen Zahnkranz, der am Um- fang der Schweltrommel 8 befestigt ist. Die Lager der Schwel¬ trommel 8 sind mit 27 bezeichnet.The rotary movement of the smoldering drum 8 about its longitudinal axis 10 is brought about by a drive 24 in the form of a gear which is connected to a motor 26. The drive means 24, 26 work, for example, on a toothed ring which is connected to the catch the smoldering drum 8 is attached. The bearings of the smoldering drum 8 are designated 27.
Aus Figur 1 wird deutlich, daß die Heizrohre 12 jeweils mit ihrem einen Ende an einer ersten Endplatte 28 und mit ihrem anderen Ende an einer zweiten Endplatte 30 befestigt sind. Die Befestigung an den Endplatten 28, 30 ist so getroffen, daß sich bevorzugt eine leichte Austauschbarkeit der Heizroh¬ re 12 ergibt. Das Ende der Heizrohre 12 ragt jeweils durch eine Öffnung aus dem Innenraum 13 nach links in die Ausla߬ kammer 16 bzw. nach rechts in die Einlaßkammer 14 hinein. Die Achse der Heizrohre 12 ist dabei jeweils senkrecht zur Ober¬ fläche der Endplatten 28, 30 ausgerichtet. Bei der gezeigten Konstruktion ist beachtet, daß die einzelnen Heizrohre 12 thermisch und mechanisch hoch beansprucht sind, und daß sich die Endplatten 28, 30, die auch als Rohrplatten oder Trommel¬ rohrböden bezeichnet werden könnten, um die Längsachse 10 der Schweltrommel 8 mitdrehen.From Figure 1 it is clear that the heating tubes 12 are each fixed at one end to a first end plate 28 and at the other end to a second end plate 30. The attachment to the end plates 28, 30 is such that there is preferably an easy interchangeability of the heating tubes 12. The end of the heating pipes 12 projects through an opening from the interior 13 to the left into the outlet chamber 16 or to the right into the inlet chamber 14. The axis of the heating tubes 12 is oriented perpendicular to the surface of the end plates 28, 30. In the construction shown, it is noted that the individual heating tubes 12 are subjected to high thermal and mechanical stresses, and that the end plates 28, 30, which could also be referred to as tube plates or drum tube sheets, rotate along the longitudinal axis 10 of the carbonization drum 8.
Von Bedeutung ist nun, daß zwischen den Endplatten 28, 30 zwei Stützstellen X, Y zum Stützen der (andernfalls mögli¬ cherweise durchhängenden) Heizrohre 12 vorgesehen sind. In Transportrichtung des Abfalls A gesehen liegt die erste Stützstelle X bei einem Drittel (1/3 1) und die zweite Stütz- stelle Y bei zwei Dritteln (2/3 1) der Gesamtlänge 1 derIt is important that two support points X, Y are provided between the end plates 28, 30 to support the (otherwise sagging) heating pipes 12. Seen in the direction of transport of waste A, the first support point X is one third (1/3 1) and the second support point Y is two thirds (2/3 1) of the total length 1 of
Schweltrommel 8. Von Bedeutung ist weiterhin, daß jede Stütz¬ stelle X, Y unterteilt ist in p = 3 im Abstand a zueinander beabstandete Teil-Abstützungen, denen jeweils ein Konsolen- Arrangement I, II bzw. III zugeordnet ist. Der Abstand a kann dabei zum Beispiel a = 1 m betragen. Jedes der Konsolen-Ar¬ rangements I, II, III (vergleiche Figuren 3 bis 5) enthält dabei mehrere, in derselben Ebene liegende Trag- oder Stütz- konsolen in Form von gerundeten Lochplatten aus Metall, zum Beispiel aus Stahl. Diese sind in den Figuren 3 bis 5 mit den Bezugszeichen la, Ib, Ic, Id und Ha, Ilb, IIc, Ild sowie lila, Illb, IIIc und Illd bezeichnet. Mit anderen Worten: Das erste Konsolen-Arrangement I nach Figur 3 umfaßt die in eini- gern Abstand voneinander an der Innenwand 33 drehversetzt be¬ festigten, bevorzugt verschweißten Stützkonsolen la, Ib, Ic und Id. Die beiden Stützkonsolen la, Ic sowie Ib, Id haben jeweils paarweise dieselbe (außen abgerundete) Konfiguration. Es handelt sich dabei, wie dargelegt, insbesondere um mit Lö¬ chern versehene Metallplatten. Entsprechend besitzt das zwei¬ te Konsolen-Arrangement II nach Figur 4 die in derselben Ebene drehversetzten Stützkonsolen Ha, Ilb, IIc und Ild. Auch hier haben wieder jeweils zwei einander gegenüberlie- gende Stützkonsolen Ha, IIc sowie Ilb, Ild dieselbe abgerun¬ dete Konfiguration. Und entsprechend umfaßt nach Figur 5 das dritte Konsolen-Arrangement III die vier in einer Ebene lie¬ genden, gegeneinander drehversetzten und beabstandeten Stützkonsolen lila, Illb, IIIc und Illd. Auch beim dritten Konsolen-Arrangement III nach Figur 5 sind die beiden jeweils gegenüberliegend an der Innenwand 33 festgemachten Stützkon¬ solen lila, IIIc sowie Illb, Illd in gleicher Weise ausge¬ führt.Smoldering drum 8. It is also important that each support point X, Y is subdivided into p = 3 partial supports spaced apart from each other, to which a bracket arrangement I, II or III is assigned. The distance a can be, for example, a = 1 m. Each of the console arrangements I, II, III (compare FIGS. 3 to 5) contains a plurality of support or support consoles located in the same plane in the form of rounded perforated plates made of metal, for example made of steel. These are designated in FIGS. 3 to 5 with the reference symbols la, Ib, Ic, Id and Ha, Ilb, IIc, Ild and purple, Illb, IIIc and Illd. In other words: The first console arrangement I according to FIG. like spaced apart from one another on the inner wall 33, preferably welded, preferably welded, support brackets la, Ib, Ic and Id. The two support brackets la, Ic and Ib, Id each have the same configuration (rounded off on the outside) in pairs. As stated, these are in particular metal plates provided with holes. Accordingly, the second bracket arrangement II according to FIG. 4 has the support brackets Ha, Ilb, IIc and Ild which are rotatably offset in the same plane. Here, too, two opposite support brackets Ha, IIc and Ilb, Ild each have the same rounded configuration. And accordingly, according to FIG. 5, the third bracket arrangement III comprises the four support brackets lilac, Illb, IIIc and Illd lying in one plane, rotatably offset from one another and spaced apart. In the case of the third console arrangement III according to FIG. 5, the two support brackets purple, IIIc and Illb, Illd respectively, which are fastened opposite each other on the inner wall 33, are designed in the same way.
Es soll noch einmal hervorgehoben werden: Die Ebene derIt should be emphasized once again: the level of
Stützkonsolen la bis Id nach Figur 3 ist von der Ebene der Stützkonsolen Ha bis Ild nach Figur 4 um den Abstand a in Längsrichtung versetzt. Entsprechendes gilt für die Ebene der Stützkonsolen lila bis Illd nach Figur 5; auch hier beträgt der Abstand wiederum a.Support brackets la to Id of Figure 3 is offset from the plane of the support brackets Ha to Ild of Figure 4 by the distance a in the longitudinal direction. The same applies to the level of the support brackets purple to Illd according to Figure 5; here too the distance is again a.
Die Heizrohre 12 können in einer Konfiguration angeordnet sein, wie sie in Figur 2 sowie in den Figuren 3 bis 5 darge¬ stellt ist. Danach gibt es eine Vielzahl peripher angeordne- ter Heizrohre 12 und eine Vielzahl etwa radial (entlang ge¬ krümmter Linien) angeordneter Heizrohre 12 zur Beheizung des mehr zentral liegenden Abfalls. Die Krümmung richtet sich nach der Drehung der Schweltrommel 8, die durch einen Pfeil 35 angedeutet ist.The heating tubes 12 can be arranged in a configuration as shown in FIG. 2 and in FIGS. 3 to 5. Then there are a plurality of peripherally arranged heating tubes 12 and a plurality of heating tubes 12 arranged approximately radially (along curved lines) for heating the more centrally located waste. The curvature depends on the rotation of the smoldering drum 8, which is indicated by an arrow 35.
In Figur 2 ist angenommen, daß alle Heizrohre 12 an einer Stützstelle X oder Y durch eine einzige (gestrichelt einge- In FIG. 2 it is assumed that all heating pipes 12 at a support point X or Y are replaced by a single one (dashed
gungs-Konfiguration von Figur 4 für das Konsolen-Arrangement III und die Befestigungs-Konfiguration von Figur 5 würde für das Konsolen-Arrangement II gelten.4 configuration for the console arrangement III and the fastening configuration of FIG. 5 would apply to the console arrangement II.
Nach Figur 6 sind wiederum p = 3 beabstandete Teil-Abstützun¬ gen an jeder Stützstelle X, Y vorgesehen. Jedes Konsolen-Ar¬ rangement I, II und III umfaßt wiederum jeweils vier in der¬ selben Ebene liegende Stützkonsolen la bis Id, Ha bis Ild bzw. lila bis Illd. Hier ist jedoch eine andere Konfiguration der Heizrohre 12 als in Figur 2 gewählt. Im vorliegenden Fall folgen aufeinander sechs radial nebeneinanderliegende, drei am Umfang nebeneinanderliegende, drei radial nebeneinander¬ liegende und anschließend wieder drei am Umfang verteilt an¬ geordnete Heizrohre 12, etc. Im vorliegenden Fall zeigt der Blick V-V (vergleiche Figur 1) wiederum die Anordnung sämtli¬ cher Heizrohre 12 sowie Stützkonsolen la bis Illd, die je¬ weils Gruppen dieser Heizrohre 12 zugeordnet sind. In Um- fangεrichtung gesehen benachbarte Stützkonsolen haben auch hier wieder einen unterschiedlichen Außenumfang. Die Stütz- konsolen la bis Illd sind hier eckig ausgeführt. Bemerkens¬ wert ist, daß - in Drehrichtung des Pfeils 35 gesehen - der Stützkonsole la die Stützkonsole lila und dieser die Stütz¬ konsole Ha folgt. Das bedeutet, daß zwischen den beiden Kon¬ solen-Arrangements I und II dem Abfall A ein beträchtlicher Freiraum für den Durchgang zur Verfügung steht. Auch hier wird deutlich, daß die gemäß der Blickrichtung V-V projezier¬ te Fläche an jeder Teil-AbStützung durch Einbringen der ein¬ zelnen Stützkonsolen la bis Illd relativ wenig von ihrer Transportleistungsfähigkeit eingebüßt hat. Auch hier gibt es einen großen freien Querschnitt, und der Abfall A in Form des Festgutes f sowie der Schwelgase s kann sich sozusagen an der in die Teil-Abstützungen aufgeteilten Stützstelle X sowie auch an der Stützstelle Y "durchschlängeln" .According to FIG. 6, p = 3 spaced partial supports are again provided at each support point X, Y. Each console arrangement I, II and III in turn comprises four support consoles la to Id, Ha to Ild and lilac to Illd, respectively, lying in the same plane. Here, however, a different configuration of the heating tubes 12 is selected than in Figure 2. In the present case, six radially adjacent heating tubes 12, three adjacent to one another on the circumference, three radially adjacent to one another and then again three distributed around the circumference, etc. follow one another. In the present case, the view VV (see FIG. 1) again shows the arrangement of all ¬ cher heating tubes 12 and support brackets la to Illd, which are each assigned to groups of these heating tubes 12. Support brackets that are adjacent in the circumferential direction also have a different outer circumference here. The support brackets la to Illd are square here. It is noteworthy that - seen in the direction of rotation of arrow 35 - the support bracket la is followed by the purple support bracket and this is followed by the support bracket Ha. This means that between the two console arrangements I and II waste A has a considerable amount of free space for passage. Here, too, it becomes clear that the area projected according to the viewing direction V-V on each partial support has lost relatively little of its transport performance by introducing the individual support brackets Ia to Illd. Here, too, there is a large free cross section, and the waste A in the form of the solid f and the carbonization gases s can, so to speak, "snake through" at the support point X divided into the partial supports and also at the support point Y.
Dasselbe gilt im Ergebnis auch für die Ausführungsform nach Figur 7. Hier sind nur p = 2 beabstandete Teil-Abstützungen pro Stützstelle X und Y vorgesehen. Die Konfiguration der In the result, the same also applies to the embodiment according to FIG. 7. Here, only p = 2 spaced partial supports per support point X and Y are provided. The configuration of the
sich ein unzulässiges Durchbiegen der Heizrohre 12 infolge des Eigengewichts dieser Heizrohre 12 und des aufliegenden Abfalls A ergeben. Um den Transport ohne Rückstau sicherzu¬ stellen, ist jede Stützstelle X und Y gestaffelt ausgeführt. Im bevorzugten Ausführungsbeispiel besitzt jede Stützstelle X, Y eine Dreiergruppe an Konsolen-Arrangements I, II, III. Diese Staffelung hält den Widerstand, der sich dem Transport des Abfalls in der Heiztrommel 12 entgegenstellt, in vertret¬ baren Grenzen. there is an inadmissible bending of the heating tubes 12 due to the weight of these heating tubes 12 and the waste A lying thereon. In order to ensure transport without backwater, each support point X and Y is staggered. In the preferred exemplary embodiment, each support point X, Y has a group of three console arrangements I, II, III. This staggering keeps the resistance, which opposes the transport of the waste in the heating drum 12, within reasonable limits.
