Description

Die vorliegende Erfindung betrifft eine Verdampferbaugruppe, insbesondere für einen Verdampferbrenner eines Fahrzeugheizgeräts oder einen Reformer, umfassend einen Verdampfermediumträger und an einer einer Verdampferkammer zugewandt zu positionierenden Seite des Verdampfermediumträgers ein poröses Verdampfermedium mit einer Mehrzahl von Verdampfermediumlagen.The present invention relates to an evaporator assembly, in particular for an evaporator burner of a vehicle heater or a reformer, comprising an evaporator medium carrier and on a side facing the evaporator chamber to be positioned side of the evaporator medium carrier, a porous evaporator medium having a plurality of evaporator medium layers.

Eine derartige Verdampferbaugruppe ist aus der DE 10 2004 057 757 A1 bekannt. Das in einem schalenartigen Verdampfermediumträger angeordnete poröse Verdampfermedium ist mit zwei Verdampfermediumlagen aufgebaut. Diese Verdampfermediumlagen wiederum sind aus Sintermaterial aufgebaut, also aus feinem Partikelmaterial, das durch Versintern zu einer festen, jedoch porösen Struktur verbunden ist. Durch den mehrlagigen Aufbau des Verdampfermediums wird es möglich, eine Abstufung der Porosität zu schaffen, so dass beispielsweise diejenige Verdampfermediumlage bzw. derjenige Verdampfermediumbereich, der einer Brennkammer bzw. Verdampferkammer zugewandt liegt und mithin diejenige Oberfläche bereitstellt, an welcher die Abdampfung stattfindet, mit geringerer Porosität ausgebildet ist, also eine feinere Porenstruktur aufweist, als derjenige Bereich, welcher den allgemein flüssigen Brennstoff aus einer Brennstoffleitung aufnimmt.Such evaporator assembly is known from DE 10 2004 057 757 A1 known. The arranged in a shell-like evaporator medium carrier porous evaporator medium is constructed with two evaporator medium layers. These evaporator medium layers, in turn, are made of sintered material, ie of fine particulate material, which is connected by sintering to form a solid, but porous structure. The multilayer structure of the evaporator medium makes it possible to provide a gradation of the porosity, so that, for example, that evaporator medium layer or that evaporator medium region which faces a combustion chamber or evaporator chamber and thus provides the surface at which the evaporation takes place has a lower porosity is formed, that has a finer pore structure than that region which receives the generally liquid fuel from a fuel line.

Es hat sich gezeigt, dass beim Einsatz derartiger aus Sintermaterial aufgebauter Verdampfermedien bzw. Verdampfermediumlagen, ähnlich wie bei aus Vliesmaterial oder Schaumkeramik oder dergleichen aufgebauten Verdampfermedien, eine sehr gleichmäßige Porosität über den gesamten Volumenbereich nicht erhalten werden kann. Aufgrund des Herstellungsvorgangs bestehen lokal Abweichungen, die einerseits zu einer ungleichmäßigen Kapillarförderwirkung und mithin einer ungleichmäßigen Brennstoffverteilung innerhalb des porösen Verdampfermedium führen können, und die weiterhin insbesondere dann, wenn lokal sehr feine Porenstrukturen entstehen, die Gefahr der Verstopfung durch feinste auch im Brennstoff mitgeführte Partikel mit sich bringen.It has been found that, when using such evaporator media or evaporator media layers constructed of sintered material, a very uniform porosity over the entire volume range can not be obtained, similar to evaporator media constructed from nonwoven material or foamed ceramic or the like. Due to the manufacturing process, local deviations exist, which on the one hand can lead to an uneven Kapillarförderwirkung and thus a nonuniform fuel distribution within the porous evaporator medium, and continue Especially when locally very fine pore structures arise, the risk of clogging by the finest particles also entrained in the fuel bring with it.

Es ist die Aufgabe der vorliegenden Erfindung, eine Verdampferbaugruppe, insbesondere für den Verdampferbrenner eines Fahrzeugheizgeräts oder einen Reformer, vorzusehen, mit welchem eine zuverlässige, definierte Verteilung des in das poröse Verdampfermedium eingeleiteten flüssigen Materials erzielt werden kann.It is the object of the present invention to provide an evaporator assembly, in particular for the evaporator burner of a vehicle heater or a reformer, with which a reliable, defined distribution of the liquid material introduced into the porous evaporator medium can be achieved.

Erfindungsgemäß wird diese Aufgabe gelöst durch eine Verdampferbaugruppe, insbesondere für einen Verdampferbrenner eines Fahrzeugheizgeräts oder einen Reformer, umfassend einen Verdampfermediumträger und an einer einer Verdampferkammer zugewandt zu positionierenden Seite des Verdampfermediumträgers ein poröses Verdampfermedium mit einer Mehrzahl von Verdampfermediumlagen.According to the invention, this object is achieved by an evaporator assembly, in particular for an evaporator burner of a vehicle heater or a reformer, comprising an evaporator medium carrier and on a side of the evaporator medium carrier facing an evaporator chamber a porous evaporator medium with a plurality of evaporator medium layers.

Dabei ist dann weiter vorgesehen, dass alle Verdampfermediumlagen mit Gewebematerial aufgebaut sind.It is then further provided that all evaporator media layers are constructed with fabric material.

Bei dem erfindungsgemäßen Aufbau einer Verdampferbaugruppe ist also zunächst durch die mehrlagige Ausgestaltung des porösen Verdampfermediums dafür gesorgt, dass die Verteilungscharakteristik in definierter Art und Weise vorgegeben werden kann. Andererseits ist durch den Einsatz von ausschließlich mit Gewebestruktur aufgebauten Verdampfermediumlagen dafür gesorgt, dass im gesamten Volumenbereich aufgrund der definierten Gewebestruktur auch definierte Porositätsverhältnisse bestehen. Die Gefahr einer ungleichmäßigen bzw. undefinierten Brennstoff- bzw. Flüssigkeitsverteilung kann somit ausgeschlossen werden.In the structure of an evaporator assembly according to the invention, therefore, it is first provided by the multilayer design of the porous evaporator medium that the distribution characteristic can be specified in a defined manner. On the other hand, the use of evaporator media layers constructed exclusively with tissue structure ensures that defined porosity conditions also exist in the entire volume range on account of the defined tissue structure. The risk of uneven or undefined fuel or liquid distribution can thus be excluded.

Der Verdampfermediumträger kann beispielsweise schalenartig aufgebaut sein.The evaporator medium carrier may be constructed, for example, shell-like.

Weiterhin wird vorgeschlagen, dass eine Verdampfermediumlage, welche eine der Verdampfungskammer zugewandt zu positionierende Verdampfermediumoberfläche bereitstellt, mit feinerer Gewebestruktur ausgebildet ist, als eine an den Verdampfermediumträger angrenzende Verdampfermediumlage. Auf diese Art und Weise kann einerseits an dem dem Verdampfermediumträger nahe liegenden Bereich der flüssige Brennstoff sehr schnell aufgenommen und in dieser Verdampfermediumlage vorverteilt werden, während an der der Verdampfungskammer zugewandten Seite durch die feinere Struktur eine sehr gleichmäßige, feingliedrige Abdampfung erreicht werden kann. Beispielsweise kann dazu vorgesehen sein, dass die Feinheit der Gewebestruktur der Verdampfermediumlagen in Richtung von einer Verdampfermediumlage, welche eine der Verdampfungskammer zugewandt zu positionierende Verdampfermediumoberfläche bereitstellt, zu einer an den Verdampfermediumträger angrenzenden Verdampfermediumlage abnimmt.Furthermore, it is proposed that an evaporator medium layer which provides an evaporator medium surface facing the evaporation chamber to be positioned is formed with a finer fabric structure than an evaporator medium layer adjoining the evaporator medium carrier. In this way, on the one hand, the liquid fuel can be absorbed very quickly on the one hand close to the evaporator medium carrier and pre-distributed in this evaporator medium, while a very uniform, finely graduated evaporation can be achieved on the side facing the evaporation chamber by the finer structure. For example, it may be provided that the fineness of the tissue structure of the evaporator medium layers decreases in the direction of an evaporator medium layer, which provides an evaporator medium surface to be positioned facing the evaporation chamber, to an evaporator medium layer adjoining the evaporator medium carrier.

Um die Flüssigkeit, also beispielsweise flüssigen Brennstoff, sehr schnell aufnehmen zu können und vorverteilen zu können, wird vorgeschlagen, dass der Durchmesser der Fäden der an den Verdampfermediumträger angrenzenden Verdampfermediumlage im Bereich von 0,16 bis 0,5 mm liegt.In order to be able to absorb the liquid, for example liquid fuel, very quickly and to be able to distribute it, it is proposed that the diameter of the filaments of the evaporator medium layer adjoining the evaporator medium carrier be in the range of 0.16 to 0.5 mm.

Weiterhin wird zum Erzielen einer sehr gleichmäßigen Verteilung an der einer Verdampfungskammer zugewandten Seite vorgeschlagen, dass der Durchmesser der die Verdampfermediumoberfläche bereitstellenden Verdampfermediumlage im Bereich von 0,05 bis 0,25 mm liegt.Furthermore, in order to achieve a very even distribution on the side facing an evaporation chamber, it is proposed that the diameter of the evaporator medium layer providing the evaporator medium surface is in the range of 0.05 to 0.25 mm.

Insbesondere dann, wenn eine Verdampferbaugruppe bei einem Verdampferbrenner eingesetzt wird, entstehen im Bereich dieser Verdampferbaugruppe durch die Verbrennung des verdampften Brennstoffs sehr hohe Temperaturen. Es wird daher vorgeschlagen, dass wenigstens eine Verdampfermediumlage mit Metallfäden aufgebaut ist. Es ist also von Bedeutung, dass bei dem erfindungsgemäßen Aufbau vor allem die den hohen Temperaturen stark ausgesetzten Bereiche aus thermisch beständigem Material aufgebaut sind.In particular, when an evaporator assembly is used in an evaporator burner, arise in the region of this evaporator assembly by the combustion of the vaporized fuel very high temperatures. It is therefore proposed that at least one evaporator medium layer is constructed with metal filaments. It is therefore important that in the structure according to the invention, in particular, the areas which are highly exposed to the high temperatures and which are thermally stable Material are constructed.

Weiterhin kann vorgesehen sein, dass wenigstens eine Verdampfermediumlage mit Keramikfäden aufgebaut ist. Auch Keramikmaterial ist ein thermisch sehr beständiges Material und weist insbesondere den Vorteil einer vergleichsweise starken thermischen Isolationswirkung auf.Furthermore, it can be provided that at least one evaporator medium layer is constructed with ceramic filaments. Also, ceramic material is a thermally highly resistant material and in particular has the advantage of a comparatively strong thermal insulation effect.

Es kann daher weiter vorgesehen sein, dass die wenigstens eine mit Keramikfäden aufgebaute Verdampfermediumlage eine Verdampfermediumoberfläche bereitstellt, welche einer Verdampfungskammer zugewandt zu positionieren ist. Auf diese Art und Weise wird dafür gesorgt, dass die von der Verdampfungskammer weiter entfernt liegenden Bereiche thermisch abgeschirmt werden, was insbesondere beim Einsatz von bei niedrigen Temperaturen siedenden Brennstoffen bzw. Flüssigkeiten vorteilhaft ist.It may therefore be further provided that the at least one evaporator medium layer constructed with ceramic filaments provides an evaporator medium surface which is to be positioned facing an evaporation chamber. In this way it is ensured that the areas further away from the evaporation chamber are thermally shielded, which is advantageous in particular when using low-boiling fuels or liquids.

Alternativ ist es möglich, dass die wenigstens eine mit Keramikfäden aufgebaute Verdampfermediumlage die an den Verdampfermediumträger angrenzende Verdampfermediumlage ist. Auf diese Art und Weise wird zwar der unmittelbare Bereich der Flüssigkeitseinleitung thermisch isoliert. Die näher an der Verdampfungskammer liegenden Bereiche werden jedoch weniger stark isoliert, so dass die beispielsweise bei Verbrennung entstehende Wärme verstärkt dazu genutzt werden kann, das poröse Verdampfermedium selbst und mithin auch die darin enthaltene Flüssigkeit, also beispielsweise Brennstoff, zu erwärmen.Alternatively, it is possible for the at least one evaporator medium layer constructed with ceramic filaments to be the evaporator medium layer adjoining the evaporator medium carrier. In this way, although the immediate area of the liquid introduction is thermally isolated. However, the areas closer to the evaporation chamber are less strongly isolated, so that the heat produced, for example, during combustion can be used to heat the porous evaporator medium itself and thus also the liquid contained therein, for example fuel.

In der Fig. 1 ist eine aus dem Stand der Technik bekannte Brennkammerbaugruppe 10 für einen Verdampferbrenner gezeigt. Die Brennkammerbaugruppe 10 umfasst ein Brennkammergehäuse 12 mit einer Umfangswandung 14 und einem Bodenbereich 16, so dass sich insgesamt eine topfartige Struktur ergibt. Am Bodenbereich 16 ist eine allgemein mit 18 bezeichnete Verdampferbaugruppe vorgesehen. Diese umfasst einen beispielsweise aus Blechmaterial geformten schalenartigen Träger 20, der an seinem Bodenbereich 22 eine von einer Brennkammer 24 weg gerichtete, trichterartige Ausformung 26 aufweist. In diese mündet eine Brennstoffleitung 28 ein.In the Fig. 1 For example, a combustor combustor assembly 10 known in the art is shown. The combustor assembly 10 includes a combustor shell 12 having a peripheral wall 14 and a bottom portion 16 to give a total cup-like structure. At the bottom portion 16, a generally designated 18 evaporator assembly is provided. This comprises a shell-like carrier 20 which is formed, for example, from sheet metal material and has a funnel-like formation 26 directed away from a combustion chamber 24 at its bottom region 22. In this opens a fuel line 28 a.

In dem schalenartigen Träger 20 ist ein poröses Verdampfermedium 30 vorgesehen, das mit zwei Verdampfermediumlagen 32, 34 aufgebaut ist. Die der Brennkammer 24 näher liegende Verdampfermediumlage 32 stellt eine Verdampfermediumoberfläche 36 bereit, über welche der durch die Brennstoffleitung 28 in das poröse Verdampfermedium 30 eingeleitete flüssige Brennstoff, nachdem er im Innenvolumenbereich des porösen Verdampfermediums 30 durch Kapillarförderwirkung und ggf. auch Schwerkrafteinfluss verteilt wurde, in die Brennkammer 24 abdampfen kann. Die Verdampfermediumlage 34, welche an dem Verdampfermediumträger 20 bzw. dessen Bodenbereich 22 angrenzend positioniert ist, kann beispielsweise mit gröberer Porenstruktur, also größerer Porosität, ausgebildet sein, als die Verdampfermediumlage 32, so dass der aus der Brennstoffleitung 28 in die Verdampfermediumlage 34 eingeleitete flüssige Brennstoff aufgrund der größeren Porosität, also der weniger feinen Porenstruktur, sehr schnell vorverteilt wird, bevor er dann nach Übergang in die Verdampfermediumlage 32 fein verteilt wird, so dass eine sehr gleichmäßige Brennstoffabdampfung über die gesamte Verdampfermediumoberfläche 36 erfolgen kann.In the shell-like carrier 20, a porous evaporator medium 30 is provided, which is constructed with two evaporator medium layers 32, 34. The evaporator medium layer 32, which is closer to the combustion chamber 24, provides an evaporator medium surface 36, via which the liquid fuel introduced into the porous evaporator medium 30 through the fuel line 28 has been distributed in the interior volume region of the porous evaporator medium 30 by capillary action and possibly also the influence of gravity Burning chamber 24 can evaporate. The evaporator medium layer 34, which is positioned adjacent to the evaporator medium carrier 20 or its bottom region 22, may be formed, for example, with a coarser pore structure, ie greater porosity, than the evaporator medium layer 32, so that the liquid fuel introduced from the fuel line 28 into the evaporator medium layer 34 due to the larger porosity, so the less fine pore structure, is pre-distributed very quickly before it is then finely distributed after passing into the evaporator medium layer 32, so that a very uniform Brennstoffabdampfung over the entire evaporator medium surface 36 can take place.

Am Bodenbereich 16 des Brennkammergehäuses 12 kann eine elektrisch erregbare Heizeinrichtung 38 vorgesehen sein, die durch den Kontakt mit dem Bodenbereich 22 des schalenartigen Verdampfermediumträgers 20 bei Erregung diesen erwärmt und somit insbesondere in einer Startphase, in welcher in der Brennkammer 24 noch keine Verbrennung abläuft, zu einer verstärkten Brennstoffabdampfung beiträgt. Weiter erkennt man, dass dort, wo die trichterförmige Ausformung 26 im Verdampfermediumträger 20 vorgesehen ist, also dort, wo auch der flüssige Brennstoff in das poröse Verdampfermedium 30 eingeleitet wird, zwischen den beiden Verdampfermediumlagen 32, 34 ein plattenartiges Ablenkelement 40 angeordnet ist, welches dafür sorgt, dass der eingeleitete flüssige Brennstoff in diesem Bereich nicht unmittelbar in die Verdampfermediumlage 32 eintreten kann, so dass die gleichmäßige Verteilung im gesamten Volumenbereich des porösen Verdampfermediums 30 noch weiter begünstigt wird.At the bottom region 16 of the combustion chamber housing 12, an electrically energizable heating device 38 may be provided which, upon contact with the bottom region 22 of the shell-like evaporator medium carrier 20, heats the latter and thus in particular during a start phase in which combustion is not yet taking place in the combustion chamber 24 contributes to increased Brennstoffabdampfung. It can further be seen that where the funnel-shaped formation 26 is provided in the evaporator medium carrier 20, ie where the liquid fuel is introduced into the porous evaporator medium 30, a plate-like deflection element 40 is arranged between the two evaporator medium layers 32, 34 ensures that the introduced liquid fuel in this area can not enter directly into the evaporator medium layer 32, so that the uniform distribution throughout the volume range of the porous evaporator medium 30 is favored even further.

Es sei darauf hingewiesen, dass der vorangehend beschriebene und in Fig. 1 gezeigte Aufbau einer Brennkammerbaugruppe nur beispielhaft ist und in verschiedensten Aspekten variiert werden kann. Auch sei darauf hingewiesen, dass eine derartige Brennkammerbaugruppe selbstverständlich auch in einem Reformer eingesetzt werden kann, um ein Gemisch aus Luft, ggf. Wasser oder Wasserdampf, und Kohlenwasserstoffdampf zu erzeugen, das dann in einer katalytischen Reaktion in Reformat umgesetzt wird. Auch in einem derartigen Einsatzbereich kann dann durch Erregen eines Zündorgans 42, ebenso wie dies bei einem Einsatz als Brennkammer der Fall ist, die Verbrennung gestartet werden, insbesondere auch um die dann folgenden Systemkomponenten eines Reformers vorzuwärmen.It should be noted that the previously described and in Fig. 1 shown construction of a combustion chamber assembly is only exemplary and can be varied in various aspects. It should also be noted that such a combustion chamber assembly can of course also be used in a reformer to produce a mixture of air, possibly water or steam, and hydrocarbon vapor, which is then reacted in a catalytic reaction in reformate. In such a field of use as well, by exciting an ignition device 42, as is the case with use as a combustion chamber, combustion can then be started, in particular also to preheat the then following system components of a reformer.

In Fig. 2 ist der zentrale Bereich einer gemäß den Prinzipien der vorliegenden Erfindung aufgebauten Verdampferbaugruppe 18 gezeigt. Es sei hier darauf hingewiesen, dass mit zentral der Bereich der Brennstoffeinleitung angesprochen ist, welcher nicht gleichzeitig auf dem geometrischen Mittelpunkt der Verdampferbaugruppe 18 entsprechen muss.In Fig. 2 Figure 3 shows the central portion of an evaporator assembly 18 constructed in accordance with the principles of the present invention. It should be noted here that the area of the fuel introduction is addressed centrally, which does not have to correspond to the geometric center of the evaporator assembly 18 at the same time.

Man erkennt in Fig. 2 die Brennstoffleitung 28, die in die trichterartige Ausformung 26 eingeführt ist und dort beispielsweise unter Einsatz eines Dichtungselements 44 dicht angeschlossen ist. In dem beispielsweise schalenartig ausgebildeten Verdampfermediumträger 20 ist wieder das poröse Verdampfermedium 30 vorgesehen, das im dargestellten Beispiel insgesamt vier Verdampfermediumlagen 32, 34, 46, 48 umfasst. Alle vier Verdampfermediumlagen 32, 34, 46, 48 sind bei dem erfindungsgemäßen Aufbau einer Verdampferbaugruppe 18 als Gewebestrukturen aufgebaut. Dabei erkennt man, dass die dem Verdampfermediumträger 20 bzw. dem Bodenbereich 22 desselben näher liegenden Verdampfermediumlagen 34, 48 mit einer gröberen Gewebestruktur bereitgestellt sind, als die der Brennkammer 24 näher positionierten bzw. auch die Verdampfermediumoberfläche 36 bereitstellende Verdampfermediumlage 32. Dies kann beispielsweise durch den Einsatz von verschieden dicken Fäden für die verschiedenen Verdampfermediumlagen 32, 34, 46, 48 erhalten werden, ebenso wie durch die pro Flächeneinheit vorgesehenen Fäden bzw. auch die Gewebebindung. So kann beispielsweise die Verdampfermediumlage 34 mit Fäden aufgebaut sein, die eine Dicke im Bereich von 0,16 bis 0,5 mm aufweisen, während die Verdampfermediumlage 32 mit Fäden aufgebaut sein kann, die eine Dicke bzw. einen Durchmesser im Bereich von 0,05 bis 0,25 mm aufweisen. Es wird somit in Richtung vom Bodenbereich 22 des Verdampfermediumträgers 20 weg beispielsweise eine über die verschiedenen Verdampfermediumlagen hinweg abnehmende Porosität erzielt, mit der Folge, dass im Bereich der Verdampfermediumoberfläche 36 eine sehr feine Porenstruktur vorhanden ist, die eine sehr gleichmäßige Brennstoffabdampfung ermöglicht, während nahe demjenigen Bereich, in welchem über die Brennstoffleitung 28 flüssiger Brennstoff eingeleitet wird, durch die vergleichsweise grobe Porenstruktur der Verdampfermediumdlagen 34 und 48 eine sehr schnelle Aufnahme und grobe Vorverteilung des flüssigen Brennstoffs erzielt wird. Hier könnte beispielsweise auch in dem dem Bereich der Einleitung des flüssigen Brennstoffs nahe liegenden Bereich zwischen zwei Verdampfermediumlagen ein Ablenkelement vorgesehen sein, wie es auch in Fig. 1 erkennbar ist. Die Verdampfermediumlagen 32, 44, 46, 48 können in dem Träger 20 beispielsweise durch materialschlüssige Verbindung, wie z. B. Versintern oder Verklebung, festgelegt sein, vorzugsweise in einem Randbereich derselben bzw. des Trägers 20. Auch die Verbindung der Lagen untereinander kann durch Verkleben erfolgen.One recognizes in Fig. 2 the fuel line 28, which is inserted into the funnel-like formation 26 and is tightly connected there, for example, using a sealing element 44. The porous evaporator medium 30 is again provided in the evaporator medium carrier 20, which has a shell-like design, for example, and in the illustrated example comprises a total of four evaporator medium layers 32, 34, 46, 48. All four evaporator medium layers 32, 34, 46, 48 are constructed in the inventive construction of an evaporator assembly 18 as fabric structures. It can be seen here that the evaporator medium layers 34, 48 closer to the evaporator medium carrier 20 or the bottom region 22 are provided with a coarser fabric structure than the evaporator medium layer 32 positioned closer to the combustion chamber 24 or also providing the evaporator medium surface 36 Use of differently thick threads for the different evaporator medium layers 32, 34, 46, 48 are obtained, as well as by the per unit area provided threads or the weave. Thus, for example, the evaporator medium layer 34 may be constructed with filaments having a thickness in the range of 0.16 to 0.5 mm, while the evaporator medium layer 32 may be constructed with filaments having a thickness or a diameter in the range of 0.05 to 0.25 mm. Thus, in the direction away from the bottom region 22 of the evaporator medium carrier 20, for example, a porosity decreasing across the various evaporator medium layers is achieved, with the result that a very fine pore structure is present in the area of the evaporator medium surface 36, which allows a very uniform fuel evaporation while being close to that Area in which liquid fuel is introduced via the fuel line 28, by the comparatively coarse pore structure of the Verdampfermediumdlagen 34 and 48 a very fast absorption and rough pre-distribution of the liquid fuel is achieved. Here, for example, a deflecting element could also be provided in the area between two evaporator medium layers that is close to the area of introduction of the liquid fuel, as it is in Fig. 1 is recognizable. The evaporator medium layers 32, 44, 46, 48 may be in the carrier 20, for example by material connection, such. As sintering or gluing, be set, preferably in an edge region thereof or the carrier 20. Also, the connection of the layers with each other can be done by gluing.

In Fig. 3 sind verschiedene Gewebebindungen gezeigt, die für die Verdampfermediumlagen 32, 34, 46, 48 eingesetzt werden können. Während die den Bodenbereich 22 des Verdampfermediumträgers 20 näher liegenden Verdampfermediumlagen 34, 48 beispielsweise mit der auch in Fig. 3b) erkennbaren Leinwandbindung aufgebaut sein können, können die der Brennkammer näher liegenden Verdampfermediumlagen 32, 46 beispielsweise mit der in Fig. 3a) erkennbaren Köper-Bindung, also beispielsweise einem Fünffach-Köper, oder der in Fig. 3c) erkennbaren Atlasbindung, also beispielsweise einem Fünfer-Atlas, aufgebaut sein. Auch andere Bindungsstrukturen, die nicht mit der in Fig. 3 erkennbaren Symmetrie aufgebaut sind, können eingesetzt werden.In Fig. 3 various tissue bonds are shown, which can be used for the evaporator medium layers 32, 34, 46, 48. While the closer the bottom portion 22 of the evaporator medium carrier 20 evaporator medium layers 34, 48, for example, with the in Fig. 3b ) can be constructed recognizable plain weave, the closer to the combustion chamber evaporator medium layers 32, 46, for example, with the in Fig. 3a ) recognizable twill weave, so for example a five-fold twill, or the in Fig. 3c ) recognizable Atlasbindung, so for example a five-atlas, be constructed. Other binding structures that do not match the in Fig. 3 can be used recognizable symmetry, can be used.

Insbesondere dann, wenn das poröse Verdampfermedium 30 vergleichsweise hohen Temperaturen ausgesetzt wird, also beispielsweise bei einer Brennkammerbaugruppe Einsatz findet, wie sie in Fig. 1 gezeigt ist, ist es von Bedeutung, dass die für die verschiedenen Verdampfermediumlagen 32, 34, 46, 48 eingesetzten Fäden aus einem Material aufgebaut sind, welches bei den erreichten Temperaturen nicht geschädigt wird. Beispielsweise können Metallfäden eingesetzt werden, oder Keramikfäden. Der Einsatz von Keramikfäden bringt den Vorteil mit sich, dass diese aufgrund ihrer thermischen Isolationsfähigkeit eine Abschirmung von weiter von einer Brennkammer entfernt liegenden Verdampfermediumlagen bzw. Bereichen der Verdampferbaugruppe 18 ermöglicht. So kann beispielsweise dann, wenn die Verdampferbaugruppe 18 in Verbindung mit niedrig siedenden Flüssigkeiten bzw. Brennstoffen eingesetzt wird, die Verdampfermediumlage 32 oder/und die Verdampfermediumlage 46 mit Keramikfäden aufgebaut werden, so dass die dahinter liegenden Bereiche, also insbesondere die eine grobe Vorverteilung vornehmenden Verdampfermediumlagen 34, 48, thermisch abgeschirmt sind und ein Sieden des Brennstoffs beim Austritt aus der Brennstoffleitung 28 bzw. bereits im Endbereich der Brennstoffleitung 28 vermieden werden kann. Grundsätzlich denkbar ist jedoch auch das Ausgestalten der Verdampfermediumlage 48 oder der Lage 34 aus derartigem Keramikfadenmaterial, so dass zwar der Bereich des Brennstoffaustritts aus der Brennstoffleitung 28 abgeschirmt ist, die Verdampfermediumlagen 32, 46 jedoch vergleichsweise stark erwärmt werden und somit durch die auch im Verbrennungsbetrieb bereitgestellte Wärme die Brennstoffabdampfung unterstützt wird. Hierzu ist es dann vorteilhaft, die zur Unterstützung der Brennstoffverdampfung vergleichsweise stark zu erwärmenden Verdampfermediumlagen aus gut wärmeleitendem Material, wie z. B. Metallmaterial, aufzubauen.In particular, when the porous evaporator medium 30 is exposed to relatively high temperatures, that is, for example, in a combustor assembly is used, as in Fig. 1 is shown, it is important that the threads used for the different evaporator medium layers 32, 34, 46, 48 are constructed of a material which is not damaged at the temperatures reached. For example, metal filaments can be used, or ceramic filaments. The use of ceramic filaments has the advantage that, due to its thermal insulation capability, it enables a shielding of evaporator medium layers or regions of the evaporator assembly 18 which are further away from a combustion chamber. Thus, for example, when the evaporator assembly 18 is used in conjunction with low-boiling liquids or fuels, the evaporator medium layer 32 and / or the evaporator medium layer 46 are constructed with ceramic filaments, so that the underlying areas, ie in particular the one coarse pre-distribution taking evaporator medium layers 34, 48, are thermally shielded and boiling of the fuel at the exit from the fuel line 28 or even in the end region of the fuel line 28 can be avoided. In principle, however, it is also conceivable to design the evaporator medium layer 48 or the layer 34 of such ceramic yarn material, so that although the area of the fuel outlet from the fuel line 28 is shielded, the evaporator medium layers 32, 46 are heated comparatively strongly and thus provided by the also in the combustion mode Heat the fuel evaporation is supported. For this purpose, it is advantageous for the support of the fuel evaporation comparatively strong to be heated evaporator medium layers of good heat conducting material such. As metal material to build.

Mit dem erfindungsgemäßen Aufbau einer Verdampferbaugruppe, bei der alle Verdampfermediumlagen mit Gewebestruktur aufgebaut sind, lassen sich verschiedene Vorteile verbinden. So ist es durch den Einsatz einer Gewebestruktur bzw. mehrerer geschichteter Gewebestrukturen leicht möglich, gezielt die Porosität zu beeinflussen, ohne dass Bereiche undefinierter Porosität entstehen. Ebenso leicht kann eine Anpassung an verschiedene Brennstoffe erfolgen, und zwar einerseits hinsichtlich der erforderlichen Porosität, welche stark im Zusammenhang steht mit der Viskosität des eingesetzten Brennstoffs, und andererseits hinsichtlich der möglicherweise erforderlichen thermischen Abschirmung durch spezielle Materialien. Weiterhin wird es möglich, derartige Verdampfermediumlagen bzw. die zum Aufbau derselben eingesetzten Fäden mit katalytischem Material zu beschichten.With the construction according to the invention of an evaporator assembly, in which all evaporator medium layers are constructed with fabric structure, various advantages can be combined. Thus, by using a fabric structure or multiple layered fabric structures, it is easily possible to specifically influence the porosity without creating areas of undefined porosity. Equally easy to adapt to different fuels, on the one hand in terms of required porosity, which is strongly related to the viscosity of the fuel used, and on the other hand with regard to the possibly required thermal shielding by special materials. Furthermore, it becomes possible to coat such evaporator medium layers or the threads used to build them up with catalytic material.

Es sei abschließend noch darauf hingewiesen, dass sich die Vorteile der erfindungsgemäßen Ausgestaltung der Verdampferbaugruppe sowohl beim Einsatz in einem Verdampferbrenner eines Fahrzeugheizgeräts oder dergleichen, als auch beim Einsatz in einem Reformer erhalten lassen.It should finally be pointed out that the advantages of the inventive design of the evaporator assembly can be obtained both when used in an evaporator burner of a vehicle heater or the like, as well as when used in a reformer.
