Definitions
- the invention relates to a device for burning oxidizable constituents contained in an exhaust air stream from a cylindrical container with a feed nozzle and a discharge nozzle.
- the feed pipe opens into a distribution space to which the inlet-side ends of angled heat exchanger tubes are connected. These extend over a substantial part of the length of the container and open into an annular chamber adjacent to an end face of the container. This surrounds a concentrically arranged burner, coaxially opposite a flue gas mixing tube. This is connected by a main combustion chamber surrounding it to an annular space which in turn surrounds it and which receives the heat exchanger tubes and to which the discharge nozzle is connected.
- Such a device is known from DE 35 32 232 C2. Since the preheating temperature of the exhaust air loaded with oxidizable components should be brought as close as possible to the combustion chamber temperature, there are high demands on the ability to compensate for changes in length, particularly under dynamic conditions, i.e. changes in temperature, volume flow and contaminant loading in the exhaust air Heat exchanger tubes. If the device is also to be operated with only a very low partial exhaust air flow, even heat exchanger tubes with laminar flow are located directly next to heat exchanger tubes with turbulent flow. The resulting different heat transfer on the tube walls inevitably leads to different tube wall temperatures, with the result that even immediately adjacent heat exchanger tubes experience different elongations.
- the heat exchanger tubes in the known device are bent outwards at their colder inflow-side ends, the exhaust air flowing outside the heat exchanger tubes being freed of the oxidizable components is guided over the pipe bends and the bent pipe sections.
- the radial legs of the heat exchanger tubes arranged on the outside can only be made relatively short, so that they, when welded into the outer wall of the container, behave too rigidly to be able to compensate for any significant expansion. Due to the shortness of the pipe legs bent outwards, these are at most suitable to compensate for differences in expansion of the pipes with one another, but not also the differences in expansion between the complete tube bundle formed from the heat exchanger tubes on the one hand and the jacket surrounding the tube bundle on the other. Therefore, a further main compensator must be provided in the known device, which makes the device considerably more expensive.
- the invention has for its object to provide a device of the type described above, which is characterized by a compact design and in which each heat exchanger tube can still experience significant changes in length without having to overcome significant adjustment forces.
- the length of these legs can be chosen to be so large, even with a relatively small container diameter, depending on the diameter of the cylindrical jacket that encloses the distribution space, that each heat exchanger tube has a considerable compensation capacity with regard to its thermal expansion disposes.
- the jacket diameter of the distribution space which is preferably arranged concentrically to the container axis, can be dimensioned so small that the size of the jacket surface is just sufficient to weld all inflow ends of the heat exchanger tubes to the jacket.
- the feed connector can be arranged coaxially to the container axis. This results in the aerodynamically favorable training possibility that the feed pipe merges smoothly into the cylindrical jacket of the distribution space.
- a bypass is provided in an end face of the distribution space coaxially with the latter and consists of a pipe socket protruding into the flue gas mixing pipe.
- the device according to the invention makes it possible to equip it with such a bypass, which is preferably only required for a certain mode of operation, with little effort, if necessary also retrospectively.
- the device essentially consists of a cylindrical container 1, which is provided on the outside with a heat-insulating insulation 2.
- the container 1 is provided on one end face 3 with a feed connector 4 arranged coaxially to the container axis and opening into a cylindrical distribution chamber 5.
- the feed pipe 4 and the distribution chamber 5 have a matching diameter and therefore merge into one another continuously.
- heat exchanger tubes 7 In a jacket 6 of the distribution chamber 5, inflow ends of heat exchanger tubes 7 are welded.
- the heat exchanger tubes 7, which are cylindrical near the wall of the container 1 are arranged and in this respect extend axially over a substantial part of the length of the container 1, each with an inlet-side leg 8 bent radially inwards.
- the outlet-side ends of the heat exchanger tubes 7 open into an annular chamber 9 which adjoins an end face 10 of the container 1.
- the end face 10 carries a burner 11 which is arranged concentrically to the annular chamber 9 and opens into a flue gas mixing tube 12. This ends at a distance from a partition wall 13 which covers the distribution chamber 5 and delimits a main combustion chamber 14 on the end face.
- the main combustion chamber 14 surrounds the flue gas mixing tube 12 and communicates with an annular space 16 via a deflection space 15.
- the heat exchanger tubes 7 are accommodated, which also penetrate the deflection space 15 and are firmly inserted into an annular disk 17 which delimits this end face.
- the annular space 16 is connected to a discharge connection 18 radially connected to the jacket of the container 1.
- a bypass 19 is provided concentrically in the partition 13, which consists of an end face closed, provided with radial bores 20 and protruding into the high-speed pipe 12 pipe socket 21.
- the bypass 19 can be released or closed more or less depending on the position of a flap 22 in the pipe socket 21.

Abstract
Die Vorrichtung besteht aus einem zylindrischen Behälter (1), in dem in einer äußeren Ringkammer (16) Bündel von Wärmetauscherrohren (7) angeordnet sind. Während der mit oxidierbaren Bestandteilen beladene Abluftstrom durch die Wärmetauscherrohre (7) einem Brenner (11) zugeführt wird, erfolgt die Ableitung des von oxidierbaren Bestandteilen befreiten Abluftstroms über die Wärmetauscherrohre (7) und umspült diese. Dadurch sind die Wärmetauscherrohre (7) Längenänderungen ausgesetzt, die dadurch kompensiert werden, daß eintrittsseitige Schenkel (8) der abgewinkelten Wärmetauscherrohre (7) radial nach innen gebogen und in einen zylindrischen Mantel (6) eingelassen sind, der den Verteilraum (5) umschließt, woran der Zuführstutzen (4) angeschlossen ist. <IMAGE>The device consists of a cylindrical container (1) in which bundles of heat exchanger tubes (7) are arranged in an outer annular chamber (16). While the exhaust air stream loaded with oxidizable components is fed through the heat exchanger tubes (7) to a burner (11), the exhaust air stream freed from oxidizable components is discharged via the heat exchanger tubes (7) and flows around them. As a result, the heat exchanger tubes (7) are exposed to changes in length, which are compensated for by the fact that legs (8) of the angled heat exchanger tubes (7) on the inlet side are bent radially inward and are embedded in a cylindrical jacket (6) which encloses the distribution space (5), where the feed connector (4) is connected. <IMAGE>
Description
Die Erfindung betrifft eine Vorrichtung zum Verbrennen von in einem Abluftstrom enthaltenen oxidierbaren Bestandteilen aus einem zylindrischen Behälter mit einem Zuführstutzen und einem Abführstutzen. Der Zuführstutzen mündet in einen Verteilraum, an den die eintrittsseitigen Enden von abgewinkelten Wärmetauscherrohren angeschlossen sind. Diese erstrecken sich über einen wesentlichen Teil der Länge des Behälters und münden in eine einer Stirnseite des Behälters benachbarte Ringkammer. Diese umschließt einen konzentrisch angeordneten Brenner, dem koaxial ein Rauchgasmischrohr gegenüberliegt. Dieses ist durch eine es umschließende Hauptbrennkammer mit einem diese wiederum umschließenden Ringraum verbunden, der die Wärmetauscherrohre aufnimmt und an den der Abführstutzen angeschlossen ist.The invention relates to a device for burning oxidizable constituents contained in an exhaust air stream from a cylindrical container with a feed nozzle and a discharge nozzle. The feed pipe opens into a distribution space to which the inlet-side ends of angled heat exchanger tubes are connected. These extend over a substantial part of the length of the container and open into an annular chamber adjacent to an end face of the container. This surrounds a concentrically arranged burner, coaxially opposite a flue gas mixing tube. This is connected by a main combustion chamber surrounding it to an annular space which in turn surrounds it and which receives the heat exchanger tubes and to which the discharge nozzle is connected.
Eine derartige Vorrichtung ist aus der DE 35 32 232 C2 bekannt. Da die Vorheiztemperatur der mit oxidierbaren Bestandteilen beladenen Abluft möglichst in die Nähe der Brennkammertemperatur gebracht werden soll, ergeben sich insbesondere unter dynamischen Bedingungen, d.h. Veränderungen hinsichtlich Temperatur, Volumenstrom und Störstoffbeladung der Abluft, hohe Anforderungen an die Kompensationsfähigkeit von Längenänderungen der Wärmetauscherrohre. Soll die Vorrichtung auch mit nur einem sehr geringen Abluftteilstrom betrieben werden, liegen sogar Wärmetauscherrohre mit laminarer Beströmung unmittelbar neben Wärmetauscherrohren mit turbulenter Beströmung. Der daraus resultierende unterschiedliche Wärmeübergang an den Rohrwandungen führt zwangsläufig zu unterschiedlichen Rohrwandtemperaturen mit der Folge, daß sogar unmittelbar benachbarte Wärmetauscherrohre unterschiedliche Längendehnungen erfahren.Such a device is known from DE 35 32 232 C2. Since the preheating temperature of the exhaust air loaded with oxidizable components should be brought as close as possible to the combustion chamber temperature, there are high demands on the ability to compensate for changes in length, particularly under dynamic conditions, i.e. changes in temperature, volume flow and contaminant loading in the exhaust air Heat exchanger tubes. If the device is also to be operated with only a very low partial exhaust air flow, even heat exchanger tubes with laminar flow are located directly next to heat exchanger tubes with turbulent flow. The resulting different heat transfer on the tube walls inevitably leads to different tube wall temperatures, with the result that even immediately adjacent heat exchanger tubes experience different elongations.
Um mit konstruktiv einfachen Mitteln den Wärmetauscherrohren insbesondere eine temperaturbedingte Ausdehnung zu ermöglichen und sie dadurch vor Schäden zu sichern, sind bei der bekannten Vorrichtung die Wärmetauscherrohre an ihren kälteren einströmseitigen Enden nach außen gebogen, wobei die außerhalb der Wärmetauscherrohre strömende, von den oxidierbaren Bestandteilen befreite Abluft über die Rohrbögen und die abgebogenen Rohrabschnitte geführt wird.In order to enable the heat exchanger tubes to expand, in particular with temperature, with structurally simple means and thereby protect them from damage, the heat exchanger tubes in the known device are bent outwards at their colder inflow-side ends, the exhaust air flowing outside the heat exchanger tubes being freed of the oxidizable components is guided over the pipe bends and the bent pipe sections.
Wenn bei der bekannten Vorrichtung relativ große Behälterdurchmesser vermieden werden sollen, müssen mit Rücksicht auf die nach außen gebogenen Enden der Wärmetauscherrohre diese im übrigen auf einem möglichst kleinen Durchmesser angeordnet werden. Die Folge davon ist, daß der Brennraum, soweit er innerhalb des Wärmetauschers eingebettet ist, nur ein sehr kleines Volumen bekommt, d. h. daß (der Hauptteil des Brennraums bzw.) ein großer Teil des gesamten Brennraums außerhalb des von den Wärmetauscherrohren umschlossenen Bereichs anzuordnen ist, wodurch sich die Länge des Behälters zwangsläufig erheblich vergrößert. Zudem können bei nach außen gebogenen Wärmetauscherrohren die radialen Schenkel der außen angeordneten Wärmetauscherrohre nur verhältnismäßig kurz ausgebildet werden, so daß diese sich, eingeschweißt in die äußere Wandung des Behälters, zu starr verhalten, um eine nennenswerte Dehnung kompensieren zu können. Bedingt durch die Kürze der nach außen abgebogenen Rohrschenkel sind diese allenfalls geeignet, Dehnungsunterschiede der Rohre untereinander auszugleichen, nicht aber auch noch die Dehnungsunterschiede zwischen dem aus den Wärmetauscherrohren gebildeten vollständigen Rohrbündel einerseits und dem das Rohrbündel umgebenden Mantel andererseits. Deshalb muß dazu bei der bekannten Vorrichtung zusätzlich ein weiterer Hauptkompensator vorgesehen werden, der die Vorrichtung erheblich verteuert.If relatively large container diameters are to be avoided in the known device, in view of the outwardly bent ends of the heat exchanger tubes, these must be arranged on the smallest possible diameter. The consequence of this is that the combustion chamber, insofar as it is embedded within the heat exchanger, only has a very small volume, ie that (the main part of the combustion chamber or) a large part of the entire combustion chamber outside of the area enclosed by the heat exchanger tubes is to be arranged, whereby the length of the container inevitably increases significantly. In addition, in the case of heat exchanger tubes which are bent outwards, the radial legs of the heat exchanger tubes arranged on the outside can only be made relatively short, so that they, when welded into the outer wall of the container, behave too rigidly to be able to compensate for any significant expansion. Due to the shortness of the pipe legs bent outwards, these are at most suitable to compensate for differences in expansion of the pipes with one another, but not also the differences in expansion between the complete tube bundle formed from the heat exchanger tubes on the one hand and the jacket surrounding the tube bundle on the other. Therefore, a further main compensator must be provided in the known device, which makes the device considerably more expensive.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art vorzuschlagen, die sich durch eine kompakte Bauweise auszeichnet und bei der trotzdem jedes Wärmetauscherrohr erhebliche Längenänderungen erfahren kann, ohne daß dazu nennenswerte Verstellkräfte überwunden werden müssen.The invention has for its object to provide a device of the type described above, which is characterized by a compact design and in which each heat exchanger tube can still experience significant changes in length without having to overcome significant adjustment forces.
Zur Lösung dieser Aufgabe wird von einer Vorrichtung der im Oberbegriff des Anspruchs 1 genannten gattungsgemäßen Art ausgegangen, welche erfindungsgemäß die im kennzeichnenden Teil desselben angegebenen Merkmale aufweist.To achieve this object, a device of the generic type mentioned in the preamble of
Durch die erfindungsgemäß radial nach innen abgewinkelten eintrittsseitigen Schenkel der Wärmetauscherrohre kann die Länge dieser Schenkel auch bei einem verhältnismäßig kleinen Behälterdurchmesser in Abhängigkeit vom Durchmesser des zylindrischen Mantels, der den Verteilraum umschließt, so groß gewählt werden, daß jedes Wärmetauscherrohr über ein erhebliches Kompensationsvermögen hinsichtlich seiner Wärmeausdehnung verfügt.Due to the radially inward angled inlet-side legs of the heat exchanger tubes according to the invention, the length of these legs can be chosen to be so large, even with a relatively small container diameter, depending on the diameter of the cylindrical jacket that encloses the distribution space, that each heat exchanger tube has a considerable compensation capacity with regard to its thermal expansion disposes.
Der Manteldurchmesser des vorzugsweise konzentrisch zur Behälterachse angeordneten Verteilraums kann so klein bemessen werden, daß die Größe der Mantelfläche gerade noch ausreicht, um sämtliche einströmseitigen Enden der Wärmetauscherrohre am Mantel anzuschweißen. So wie der Verteilraum konzentrisch zur Behälterachse angeordnet ist, läßt sich der Zuführstutzen orzugsweise koaxial zur Behälterachse anordnen. Dadurch ergibt sich die strömungstechnisch günstige Ausbildungsmöglichkeit, daß der Zuführstutzen stufenlos in den zylindrischen Mantel des Verteilraums übergeht.The jacket diameter of the distribution space, which is preferably arranged concentrically to the container axis, can be dimensioned so small that the size of the jacket surface is just sufficient to weld all inflow ends of the heat exchanger tubes to the jacket. Just as the distribution space is arranged concentrically to the container axis, the feed connector can be arranged coaxially to the container axis. This results in the aerodynamically favorable training possibility that the feed pipe merges smoothly into the cylindrical jacket of the distribution space.
Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist in einer Stirnseite des Verteilraums zu dieser koaxial ein Bypass vorgesehen, der aus einem in das Rauchgasmischrohr hineinragenden Rohrstutzen besteht.According to a particularly advantageous embodiment of the invention, a bypass is provided in an end face of the distribution space coaxially with the latter and consists of a pipe socket protruding into the flue gas mixing pipe.
Die erfindungsgemäße Vorrichtung ermöglicht es, diese mit geringem Aufwand, im Bedarfsfalle auch nachträglich, mit einem solchen Bypass auszurüsten, der vorzugsweise nur bei einer bestimmten Betriebsweise erforderlich ist.The device according to the invention makes it possible to equip it with such a bypass, which is preferably only required for a certain mode of operation, with little effort, if necessary also retrospectively.

In einem Mantel 6 der Verteilkammer 5 sind einströmseitige Enden von Wärmetauscherrohren 7 eingeschweißt. Dazu sind die Wärmetauscherrohre 7, die in Wandnähe des Behälters 1 zylinderförmig angeordnet sind und sich insoweit axial über einen wesentlichen Teil der Länge des Behälters 1 erstrecken, jeweils mit einem eintrittsseitigen Schenkel 8 radial nach innen gebogen.In a

Um wahlweise einen Teil des mit oxidierbaren Bestandteilen beladenen Abgases unter Umgehung der Wärmetauscherrohre 7, des Brenners 11 und des wesentlichsten Teils des Rauchgasmischrohrs 12 im Kurzschluß in den inneren Ringraum 14 einzuleiten, ist konzentrisch in der Trennwand 13 ein Bypass 19 vorgesehen, der aus einem stirnseitig verschlossenen, mit radialen Bohrungen 20 versehenen und in das Hochgeschwindigkeitsrohr 12 hineinragenden Rohrstutzen 21 besteht.
