Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum-Bereitstellen eines Gases, wobei das Gas in Behältern in flüssiger Form oder zusammen mit einem in einer porösen Masse verteilten Lösungsmittel unter Druck gespeichert ist, und die Behälter erwärmt werden.The invention relates to a method and an apparatus for providing a gas, the gas being stored in containers in liquid form or together with a solvent distributed in a porous mass under pressure, and the containers being heated.

Ein derartiges Verfahren ist in der DE-OS 26 50 880 beschrieben. Die Behälter sind dabei in Transportbehältern (Containern) oder in ortsgebundenen Räumen aufgestellt und werden beheizt, um eine bestimmte Entnahmemenge an gespeichertem Gas pro Zeiteinheit garantieren zu können. Unter dem Gesichtspunkt einer weitgehenden Entleerung der Behälter und der Garantie einer bestimmten Entnahmemenge pro Zeiteinheit ist eine möglichst hohe Temperatur erstrebenswert. Die Erwärmung der Behälter auf eine relativ hohe Temperatur führt aber zu einem hohen Energieverbrauch verbunden mit beträchtlichen Heizkosten.Such a method is described in DE-OS 26 50 880. The containers are placed in transport containers (containers) or in fixed rooms and are heated in order to guarantee a certain amount of gas stored per unit of time. From the point of view of extensive emptying of the containers and the guarantee of a certain withdrawal quantity per unit of time, the highest possible temperature is desirable. However, heating the containers to a relatively high temperature leads to high energy consumption combined with considerable heating costs.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren der eingangs erwähnten Art anzugeben, das nur geringe Heizkosten verursacht, durch das jedoch eine weitgehende Entleerung der Behälter nicht beeinträchtigt wird und weiterhin eine bestimmte Entnahmemenge pro Zeiteinheit garantiert ist.The invention is therefore based on the object of specifying a method of the type mentioned at the outset which causes only low heating costs, but which results in extensive Emptying the container is not affected and a certain amount of withdrawal per unit of time is still guaranteed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein oder mehrere Behälter in eine ausschließlich gasdichte Teile dieser Behälter umschließende Kapsel eingebaut wird bzw. werden, wobei der Kapselinnenraum während der Gasentnahme wenigstens zeitweise erwärmt wird, während der Außenraum der Kapsel belüftet wird.This object is achieved in that one or more containers are installed in a capsule enclosing exclusively gas-tight parts of these containers, the interior of the capsule being at least temporarily heated during gas extraction, while the exterior of the capsule is being ventilated.

Erfindungsgemäß werden die Behälter zunächst in eine Kapsel montiert. Diese ist so gestaltet, daß einerseits sicherheitstechnische Aspekte berücksichtigt werden und andererseits der zu beheizende Raum möglichst klein gehalten wird. Dabei wurde von folgender Erkenntnis ausgegangen: Der Heizenergieaufwand bei der Entnahme von Gasen aus Flaschen setzt sich hauptsächlich aus folgenden Energiebeiträgen zusammen:

  • 1. Energie für die Entlösung eines Gases aus einem Lösungsmittel, in dem das Gas gelöst ist, wobei das Gas zusammen mit dem Lösungsmittel in einer porösen Masse unter Druck verteilt ist bzw. Energie für die Verdampfung eines flüssig gespeicherten Gases.
  • 2. Energie, die erforderlich ist, um Wärmeverluste durch die Wände des beheizten Raumes auszugleichen.
  • 3. Energie, um die Wärmeverluste auszugleichen, die durch den aus sicherheitstechnischen Gründen vorgeschriebenen Luftwechsel entstehen.Diese Luftwechsel sind erforderlich, um die Bildung von zündfähigen Gas-Luft-Gemischen durch Gas, das durch Undichtigkeiten austritt, zu vermeiden.
According to the invention, the containers are first assembled in a capsule. This is designed so that safety aspects are taken into account on the one hand and on the other hand the space to be heated is kept as small as possible. The following knowledge was taken as a basis: The heating energy expenditure when removing gases from bottles is mainly composed of the following energy contributions:
  • 1. Energy for the detachment of a gas from a solvent in which the gas is dissolved, the gas being distributed together with the solvent in a porous mass under pressure or energy for the vaporization of a liquid stored gas.
  • 2. Energy that is required to compensate for heat losses through the walls of the heated room.
  • 3. Energy to compensate for the heat losses caused by the air change required for safety reasons. These air changes are necessary to avoid the formation of ignitable gas-air mixtures by gas that escapes through leaks.

Erfindungsgemäß werden die Behälter, in denen Gas zusammen mit einem in einer porösen Masse verteilten Lösungsmittel unter Druck gespeichert sind oder in denen das Gas in flüssiger Form gespeichert ist, vor der Gasentnahme in einer Kapsel eingeschlossen, durch die zwei Zonen gebildet werden. In der ersten Zore (Zone I), dem Kapselinnenraum, befinden sich ausschließlich die Teile der Behälter, in deren Bereich keine Undichtigkeiten, d.h. Gaslecks, auftreten können. Der gasdichte Teil eines Behälters ist das Behältergehäuse mit Ausnahme der Gasentnahme- bzw. Gasfüllstelle. Dieser Bereich jedes Behälters befindet sich in der zweiten Zone außerhalb der Kapsel (Zone II). Hierbei können alle Behälter in einer Kapsel oder ein Teil der Behälter in jeweils eine Kapsel eingebaut werden. Nachdem die Behälter in dieser Weise in eine oder mehrere Kapseln eingebaut worden sind, kann den Behältern Gas entnommen werden. Hierbei wird der Kapselinnenraum beheizt, während der Außenraum belüftet wird.According to the invention, the containers in which gas is stored under pressure together with a solvent distributed in a porous mass or in which the gas is stored in liquid form are enclosed in a capsule before the gas withdrawal, through which two zones are formed. In the first Zore (Zone I), the interior of the capsule, there are only the parts of the container in whose area there are no leaks, i.e. Gas leaks can occur. The gas-tight part of a container is the container housing with the exception of the gas extraction or gas filling point. This area of each container is in the second zone outside the capsule (Zone II). All containers can be installed in one capsule or some of the containers in one capsule. After the containers have been installed in this way in one or more capsules, gas can be removed from the containers. The interior of the capsule is heated while the exterior is being ventilated.

Durch diese Maßnahme, insbesondere die Trennung in zwei Zonen, wird folgendes erreicht:

  • Für die Gasentnahme ist es nur erforderlich, Zone I zu beheizen. Im Unterschied zu den bekannten Verfahren muß diese Zone nicht mehr belüftet werden, da innerhalb dieser Zone keine lösbaren Verbindungen, d.h. keine Schläuche, Armaturen und Leitungen untergebracht sind, in deren Bereich Undichtigkeiten auftreten können. Da es erfindungsgemäß unnötig ist, beheizte Luft zu wechseln, wird der unter Punkt 3 angegebene Energiebeitrag, der ein wesentlicher Heizkostenfaktor ist, auf ein Minimum reduziert. Gelingt es, die Kapselung der Behälter möglichst luftdicht vorzunehmen, so kann der auf .Luftwechsel beruhende Wärmeverlust vollständig ausgeschaltet werden.
This measure, in particular the separation into two zones, achieves the following:
  • It is only necessary to heat Zone I for gas extraction. In contrast to the known methods, this zone no longer has to be ventilated, since within this zone there are no detachable connections, ie no hoses, fittings and lines, in the area of which leaks can occur. Since, according to the invention, it is unnecessary to change heated air, the energy contribution specified under point 3, which is a significant heating cost factor, is reduced to a minimum. If it is possible to encapsulate the containers as airtight as possible, the heat loss due to air changes can be completely eliminated.

Wurden die Behälter bisher z.B. in großen Transportbehältern geliefert und während der Entnahme beheizt, so ist das erfindungsgemäß zu beheizende Volumen, d.h. der Kapselinnenraum, vergleichsweise klein. Daher ist die Oberfläche des beheizten Raumes (der Kapsel) kleiner als bisher, wodurch die unter Punkt 2 angeführten Wärmeverluste über die Wände des beheizten Raumes reduziert werden können. Diese Verluste können durch die Verwendung einer Kapsel, deren Wand mit wärmeisolierendem Material beschichtet ist oder die aus einem derartigen Material besteht, ebenfalls weitgehend ausgeschaltet werden.So far, the containers have been in large transport containers supplied and heated during removal, the volume to be heated according to the invention, ie the interior of the capsule, is comparatively small. Therefore, the surface of the heated room (the capsule) is smaller than before, which means that the heat losses mentioned under point 2 over the walls of the heated room can be reduced. These losses can also be largely eliminated by using a capsule whose wall is coated with heat-insulating material or which consists of such a material.

Erfindungsgemäß ist es möglich, die in eine Kapsel eingebauten Behälter im Freien oder in einem Raum aufzustellen. Bei einer Gasentnahme im Freien wäre dabei unter dem Gesichtspunkt möglichst geringer Wärmeverluste durch Wärmeleitung eine gute Isolierung der gesamten Kapsel wichtig. Werden die Behälter dagegen in einem Raum, z.B. in einem mobilen Container untergebracht, ist es nur erforderlich, die Teile der Kapsel, die sich an einer Außenwand des Raumes befinden, mit einem gut wärmeisolierenden Material zu versehen, während das Isoliervermögen der zur Innenseite des Raumes weisenden Wände geringer sein kann.According to the invention, it is possible to set up the containers installed in a capsule outdoors or in a room. When gas is extracted outdoors, it would be important to insulate the entire capsule from the point of view of minimizing heat loss through heat conduction. However, if the containers are in a room, e.g. Housed in a mobile container, it is only necessary to provide the parts of the capsule, which are located on an outer wall of the room, with a good heat-insulating material, while the insulating capacity of the walls facing the inside of the room may be less.

Nach einem Merkmal der Erfindung befinden sich in Zone II alle die Teile des Behälter bzw. der Entnahmevorrichtung, in deren Bereich Undichtigkeiten auftreten können. Diese Zone wird daher belüftet. Es ist jedoch nicht notwendig, Zore II zu beheizen, so daß auf diese Weise keine Heizenergie verlorengeht.According to a feature of the invention, zone II contains all the parts of the container or the removal device, in the area of which leaks can occur. This zone is therefore ventilated. However, it is not necessary to heat Zore II so that no heating energy is lost.

Mit dem erfindungsgemäßen Verfahren kann der Heizkostenaufwand auf einen Bruchteil der bisher anfallenden Kosten gesenkt werden.With the method according to the invention, the heating costs can be reduced to a fraction of the previously incurred costs.

In einer vorteilhaften Ausgestaltung des Erfindungsgedankens werden die Behälter mittels erhitzter Luft erwärmt und wird die Luft innerhalb des Kapselinnenraums umgewälzt. Die Umwälzung kann durch geeignete Vorrichtungen erzwungen werden. üblicherweise reicht jedoch die durch Temperaturunterschiede innerhalb einer Kapsel verursachte Wärmekonvektion aus. Durch diese Maßnahme wird ein Wärmestau im Bereich der Kapseldecke verhindert.In an advantageous embodiment of the inventive concept the containers are heated by means of heated air and the air is circulated within the interior of the capsule. The circulation can be forced by suitable devices. Usually, however, the heat convection caused by temperature differences within a capsule is sufficient. This measure prevents heat accumulation in the capsule area.

Mit Vorteil wird nach einer weiteren Ausgestaltung des Erfindungsgedankens die Tmperatur des Kapselinnenraums in Abhängigkeit vom Druck in den Behältern geregelt..Hierdurch ist es möglich, bei vollen Behältern eine niedrige Temperatur innerhalb der Kapsel, mit sinkendem Druck in den Behältern jedoch eine höhere Temperatur einzustellen. Im Zusammenhang mit dem Einbau der Behälter in eine Kapsel führt dieser Verfahrensschritt zu einer überraschend großen Heizkostenersparnis. Mußte bisher für die Entleerung von Behältern, die in mobilen Containern montiert waren und in diesen erwärmt wurden, ein Heizenergieverbrauch veranschlagtwerden, der etwa dem eines Einfamilienhauses während der Heizperiode entsprach, so sinkt der Energieverbrauch beim erfindungsgemäßen Verfahren auf 10% bis 20% dieses Wertes.According to a further embodiment of the concept of the invention, the temperature of the interior of the capsule is advantageously regulated as a function of the pressure in the containers. This makes it possible to set a low temperature inside the capsule when the container is full, but to set a higher temperature as the pressure in the container decreases. In connection with the installation of the containers in a capsule, this process step leads to a surprisingly large saving in heating costs. Until now, heating energy consumption, which roughly corresponded to that of a family home during the heating period, had to be estimated for the emptying of containers which were mounted in mobile containers and were heated in them, so the energy consumption in the method according to the invention drops to 10% to 20% of this value.

In einer Vorrichtung zur Durchführung des Verfahrens mit innerhalb eines Raumes angeordneten Behältern mit Entnahmevorrichtungen ist bzw. sind mit Vorteil ein oder mehrere Behälter so in eine allseitig geschlossene Kapsel eingebaut, daß sich nur die Behältergehäuse sowie eine Heizvorrichtung im Kapselinnenraum befinden, während die Gasentnahme- und Gasfüllstelle der Behälter sowie die zugehörigen Entnahmevorrichtungen außerhalb der Kapsel angeordnet sind.Beim Befüllen von Azetylenflaschen z.B. werden die Flaschen während des Füllvorganges mit Kühlwasser gekühlt.Durch die Kapselung ist es möglich, das Kühlwasser wirksamer als bisher an die Flaschen heranbringen zu können. Außerdem wird durch die Trennung erreicht, daß die Leitungen nicht mit Wasser in Berührung kommen und somit die Korrosion nicht gefördert wird.In a device for carrying out the method with containers arranged in a room with removal devices, one or more containers are or are advantageously installed in a capsule that is closed on all sides such that only the container housing and a heating device are located in the interior of the capsule, while the gas extraction and Gas filling point of the container and the associated removal devices are arranged outside the capsule. When filling acetylene bottles, for example, the bottles are cooled with cooling water during the filling process. The encapsulation makes it possible to bring the cooling water to the bottles more effectively than before. In addition, the Separation ensures that the pipes do not come into contact with water and thus the corrosion is not promoted.

In einer Ausgestaltung des Erfindungsgedankens sind mit Vorteil in einer Kapsel jeweils alle über eine gemeinsame Entnahmeleitung zu einer Bündeleinheit zusammengefaßte Behälter angeordnet. Sind die Behälter in mehreren Kapseln montiert, können'die Kapseln in dieser Anordnung jeweils getrennt voneinander beheizt werden und die Behälter dieser Kapsel unabhängig von den übrigen Behältern entleert werden.In one embodiment of the concept of the invention, all of the containers which are combined into a bundle unit via a common removal line are advantageously arranged in one capsule. If the containers are installed in several capsules, the capsules can be heated separately from each other in this arrangement and the containers of this capsule can be emptied independently of the other containers.

Nach einem weiteren Merkmal der Erfindung kann die Heizvorrichtung vorteilhafterweise ein unterhalb der Behälter in der Kapsel angeordneter Lufterhitzer sein. Z.B. kann ein Wärmetauscher mit Rippenrohren, durch die Warmwasser, Heißwasser oder Dampf strömt und dabei die Rohre umspülende Luft erwärmt, Verwendung finden.According to a further feature of the invention, the heating device can advantageously be an air heater arranged below the container in the capsule. E.g. For example, a heat exchanger with finned tubes through which hot water, hot water or steam flows and which heats air flowing around the tubes can be used.

In einer vorteilhaften Variante dieser Vorrichtung ist im Kapselinnenraum eine Wand mit Abstand und im wesentlichen parallel zu einer vertikalen Kapselwand angeordnet, wobei der zwischen der Wand und der vertikalen Kapselwand gebildete Raum den Bodenbereich der Kapsel mit dem Deckenbereich der Kapsel verbindet. Dabei sind in diesem Raum keine Behälter angeordnet. Die erwärmte Luft strömt hierbei durch den thermischen Auftrieb zwischen den Flaschenlücken vom Bereich des Kapselbodens zum Bereich der Kapseldecke.Aus diesem Bereich strömt die abgekühlte Luft über den zwischen Kapselwand und der weiteren Wand gebildeten Zwischenraum zurück. Die weitere Wand verhindert, daß sich die über den Heizkörpern emporströmende Luft mit der kühleren Luft mischt.In an advantageous variant of this device, a wall is arranged in the interior of the capsule at a distance and essentially parallel to a vertical capsule wall, the space formed between the wall and the vertical capsule wall connecting the bottom region of the capsule to the ceiling region of the capsule. No containers are arranged in this room. The heated air flows through the thermal buoyancy between the bottle gaps from the area of the capsule bottom to the area of the capsule top, from which the cooled air flows back through the space formed between the capsule wall and the further wall. The further wall prevents the air flowing over the radiators from mixing with the cooler air.

Im folgenden soll anhand schematischer Skizzen ein Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung beschrieben werden:An exemplary embodiment of a device according to the invention will be described below with the aid of schematic sketches will be:

Es zeigen:

Show it:
  • Figure 1 is a sectional view of a schematically illustrated device according to the invention
  • Figure 2 shows an embodiment of an inventive device installed in a mobile container.

In Figur 1 sind vier Flaschen 1 bis 4 dargestellt. Die Behälter stehen auf einer gelochten Bodenplatte 5, unterhalb deren zwei Heizkörper 6 angeordnet sind. Die Behälter 1 bis 4 sind von einer aus fünf Wänden bestehenden Kapsel umgeben. In der Figur sind lediglich die beiden Seitenwände 7,8 und die Decke 9 dargestellt. Die Behälter werden vor der Gasentnahme so in diese Kapsel montiert, daß lediglich die Behältergehäuse innerhalb der Kapsel angeordnet sind, während die jeweiligen Flaschenventile 10 bis 13, Schläuche 14 bis 17 sowie die gemeinsame Entnahmeleitung 18 außerhalb der Kapsel untergebracht sind. Zusammen mit dem Raum, in dem die Heizkörper 6 angeordnet sind, bildet die Kapsel einen geschlossenen, im wesentlichen luftdichten Raum. Das Material, aus dem die Kapselwände gefertigt werden, besitzt gute wärmeisolierende Eigenschaften.In Figure 1, four bottles 1 to 4 are shown. The containers stand on a perforated base plate 5, below which two radiators 6 are arranged. The containers 1 to 4 are surrounded by a capsule consisting of five walls. In the figure, only the two side walls 7, 8 and the ceiling 9 are shown. Before the gas is withdrawn, the containers are mounted in this capsule in such a way that only the container housings are arranged inside the capsule, while the respective bottle valves 10 to 13, hoses 14 to 17 and the common extraction line 18 are accommodated outside the capsule. Together with the space in which the radiators 6 are arranged, the capsule forms a closed, essentially airtight space. The material from which the capsule walls are made has good heat-insulating properties.

Nachdem die Behälter 1 bis 4 auf die geschilderte Weise in einer Kapsel eingebaut worden sind,kann den Behältern Gas, im Ausführungsbeispiel Azetylen, das zusammen mit einem in einer porösen Masse verteilten Lösungsmittel unter Druck in den Behältern gespeichert ist, entnommen werden. Während der Gasentnahme werden die Behälter beheizt, um die zur Entnahme erforderliche Lösungs-Absorptions- und/ oder Verdampfungswärme aufzubringen. In der Zeichnung ist eine Regeleinheit, über die die Temperatur des Kapselinnenraums in Abhängigkeit vom Behälterdruck geregelt werden kann, nicht dargestellt. Durch die Heizkörper 6 erwärmte Luft streicht durch die gelochte Bodenplatte 5 und zwischen den Behältern 1 und 2 bzw. 3 und 4 empor. Im Wärmekontakt mit den Behältern kühlt die Luft etwas ab und fließt zwischen den Flaschen 1 bzw. 4 und den Kapselwänden 7 bzw. 8 sowie zwischen den Behältern 2 und 3 zu den Heizkörpern 6 zurück. Dieser Skizze ist zu entnehmen, daß der Kapselinnenraum möglichst klein zu halten ist.After the containers 1 to 4 have been installed in a capsule in the manner described, gas, in the exemplary embodiment acetylene, which is stored under pressure in the containers together with a solvent distributed in a porous mass, can be removed from the containers. During the gas extraction, the containers are heated in order to apply the solution - absorption and / or evaporation heat required for the extraction. In the drawing there is a control unit which controls the temperature of the interior of the capsule depending on the container pressure can, not shown. Air heated by the radiators 6 sweeps up through the perforated base plate 5 and between the containers 1 and 2 or 3 and 4. In thermal contact with the containers, the air cools somewhat and flows back to the radiators 6 between the bottles 1 and 4 and the capsule walls 7 and 8 and between the containers 2 and 3. This sketch shows that the interior of the capsule should be kept as small as possible.

Sind die auf die beschriebene Weise montierten Behälter innerhalb eines Raumes angeordnet, ist es erforderlich, den Außenraum der Kapsel, in dem die Behälterventile 10 bis 13, die Schläuche 14 bis 17 sowie die gemeinsame Entnahmeleitung 18 untergebracht sind, zu belüften.If the containers assembled in the manner described are arranged within a space, it is necessary to ventilate the outer space of the capsule, in which the container valves 10 to 13, the hoses 14 to 17 and the common extraction line 18 are accommodated.

In Figur 2 ist eine erfindungsgemäße Vorrichtung dargestellt, bei der sich die Behälter 1,2,1',2' innerhalb eines mobilen Containers 20 befinden. Die Behälter sind zu zwei Gruppen 1 bis 2 und 1' bis 2' zusammengefaßt, die jeweils in eine eigene Kapsel eingeschlossen sind. Die beiden Gruppen sind rechts und links von einem begehbaren Mittelgang 22 angeordnet. Eine Außenwand 8, 8' der Kapseln fällt jeweils mit einer der Containerwände zusammen und ist daher nach Möglichkeit besonders gut gegen Wärmeverluste zu isolieren. In der Containerdecke befindet sich eine Lüftungsöffnung 21. Nach herkömmlichen Verfahren wurde das gesamte Containervolumen beheizt und zusätzlich der gesamte Luftinhalt mehrmals pro Stunde (ca. 3mal) gewechselt. Erfindungsgemäß wird der Containerinnenraum in zwei Zonen geteilt. Dabei wird nur die durch die Kapselwände 7 bis 9 bzw. 7' bis 9' gebildete Zone I (Kapselinnenraum) beheizt. In dieser Zone wird jedoch kein Luftwechsel vorgenommen: Dem Außenbereich der beiden Kapseln (Zone II) wird erfindungsgemäß keine Wärme zugeführt, dagegen wird dieser Bereich belüftet. In Figur 2 ist strichpunktiert eine Variante einer erfindungsgemäßen Vorrichtung eingetragen. Demnach wird zwischen den Kapselwänden 7 bis 7' und den zugehörigen Behältern 1 bzw. 2' eine zusätzliche Wand 19 bzw. 19' mit Abstand und parallel zu den Kapselwänden 7 bzw. 7' montiert. Durch die zusätzlichen Wände 19 bzw. 19' wird eine Umwälzung der Luft innerhalb der beiden Kapseln gefördert. Die durch Heizkörper 6 erwärmte Luft streicht zwischen den Behältern 1 und 2 bzw. 1' und 2' empor, kühlt dabei ab und wird aus dem Bereich der Kapseldecke über den Raum zwischen der Kapselwand 7 und der zusätzlichen Wand 19 (7' und 19') in den Bodenbereich der Kapsel geleitet.FIG. 2 shows a device according to the invention, in which the containers 1, 2, 1 ', 2' are located within a mobile container 20. The containers are combined into two groups 1 to 2 and 1 'to 2', each of which is enclosed in its own capsule. The two groups are arranged to the right and left of an accessible central aisle 22. An outer wall 8, 8 'of the capsules coincides with one of the container walls and is therefore, if possible, particularly well insulated against heat loss. There is a ventilation opening 21 in the container ceiling. The entire container volume was heated using conventional methods and the entire air content was changed several times per hour (approx. 3 times). According to the container interior is divided into two zones. Only zone I (interior of the capsule) formed by the capsule walls 7 to 9 or 7 'to 9' is heated. However, no air change is carried out in this zone: according to the invention, no heat is supplied to the outer area of the two capsules (zone II), but this area is ventilated. A variant of a device according to the invention is shown in broken lines in FIG. Accordingly, an additional wall 19 or 19 'is mounted between the capsule walls 7 to 7' and the associated containers 1 and 2 'at a distance and parallel to the capsule walls 7 and 7'. A circulation of the air within the two capsules is promoted by the additional walls 19 and 19 '. The air heated by the radiator 6 sweeps up between the containers 1 and 2 or 1 'and 2', cools down and is removed from the area of the capsule cover via the space between the capsule wall 7 and the additional wall 19 (7 'and 19' ) in the bottom area of the capsule.

Zusammenfassend läßt sich feststellen, daß durch das erfindungsgemäße Verfahren eine erhebliche Senkung des Heizenergiebedarfs erzielt werden kann.In summary, it can be stated that the method according to the invention can achieve a significant reduction in the heating energy requirement.
