Abstract
Description
Die
Erfindung betrifft eine Vorrichtung zum Umwandeln des Boil-Off-Gases
eines Kryo-Kraftstofftanks mit einer Verbrennungseinrichtung für das Boil-Off-Gas sowie mit
einem Thermoelement zur Gewinnung elektrischer Energie aus der bei
diesem Umwandlungsprozess freiwerdenden Wärme, weiterhin mit einem Hilfsenergiespeicher
zur Speicherung der so gewonnenen elektrischen Energie, aus dem
elektrische Verbraucher auch für
den Umwandlungsprozess ihre Energie beziehen. Zum technischen Umfeld
wird neben der WO 03/062005 auf die
Hiermit sollen nun weitere Verbesserungen zum soweit bekannten Stand der Technik aufgezeigt werden (= Aufgabe der vorliegenden Erfindung). Die Lösung dieser Aufgabe ist für eine Vorrichtung zum Umwandeln des Boil-Off-Gases eines Kryo-Kraftstofftanks nach dem Oberbegriff des Anspruchs 1 dadurch gekennzeichnet, dass eine Fördervorrichtung für beim Umwandlungsprozess benötigte Verbrennungsluft und/oder eine Heizeinrichtung für eine den kryogenen Kraftstoff und/oder das Boil-Off-Gas führende Leitung als ein solcher elektrischer Verbraucher vorgesehen ist. Vorteilhafte Weiterbildungen sind Inhalt der Unteransprüche.Herewith should now be further improvements to the extent known the Technique are shown (= object of the present invention). The solution this task is for a device for converting the boil-off gas of a cryogenic fuel tank according to the preamble of claim 1, characterized in that a conveyor for during the conversion process needed Combustion air and / or a heater for the cryogenic fuel and / or the boil-off gas leading Line is provided as such an electrical load. Advantageous developments are content of the dependent claims.
Eine Verbrennung des Boil-off-Gases, insbesondere eine katalytische Verbrennung desselben, geht deutlich verbessert einher und beansprucht den Katalyten bzw. dessen Trägerkörper in erheblich geringerem Umfang, wenn großer Luftüberschuss bzw. Sauerstoff-Überschuss vorliegt. Trotz einer grundsätzlich bekannten Maßnahme zur Luftförderung unter Zuhilfenahme des Saugstrahlpumpen-Effektes kann die Sauerstoff- oder Luftzufuhr mit einem Gebläse bzw. einer geeigneten elektrisch betriebenen Fördervorrichtung weiter gesteigert werden. Diese kann nun (ebenfalls) mit der durch ein Thermoelement beim Verbrennungs- oder Umwandlungsprozess gewonnenen und in einem Hilfsenergiespeicher gespeicherten elektrischen Energie aus letzterem gespeist werden.A Combustion of the boil-off gas, in particular a catalytic combustion the same, goes much better accompanied and claimed the catholyte or its carrier body in considerably smaller if there is a large excess of air or an excess of oxygen is present. Despite a principle known measure for air conveying With the aid of the suction jet pump effect, the oxygen or air supply with a blower or a suitable electrically operated conveyor device further increased become. This can now (likewise) with the by a thermocouple obtained in the incineration or conversion process and in one Auxiliary energy storage stored stored electrical energy from the latter become.
Insbesondere in Verbindung mit einer katalytischen Verbrennung bzw. Umwandlung des Boil-Off-Gases ist dessen sehr niedrige Temperatur nachteilig. Ebenfalls nachteiligerweise fehlt bei einem Neustart der Kraftstoffversorgungsanlage bzw. von einem von dieser versorgten energiewandelnden Aggregat Wärme zur Konditionierung des kryogenen Kraftstoffs. Aus diesem Grunde wird vorgeschlagen, eine Heizeinrichtung, die vorteilhafterweise mit einem Wärmespeicher versehen sein kann, entweder grundsätzlich für den aus dem Kryo-Kraftstofftank entnommenen kryogenen Kraftstoff oder zumindest für den abgegebenen Boil-Off-Kraftstoff vorzusehen, wobei diese Heizeinrichtung ebenfalls elektrisch betrieben und mit der mittels des genannten Thermoelements erzeugten elektrischen Energie zumindest indirekt versorgt wird. Alternativ oder zusätzlich ist es in diesem Zusammenhang möglich, dass die den kryogenen Kraftstoff und/oder das Boil-Off-Gas führende Leitung mit der Verbrennungseinrichtung in wärmeleitender Verbindung steht. Dieser wärmeleitende Kontakt kann vorteilhafterweise auch über das besagte Thermoelement hergestellt werden, wodurch die zur Bereitstellung von elektrischer Energie durch dasselbe nötige Temperaturdifferenz am Thermoelement sichergestellt ist.Especially in connection with a catalytic combustion or conversion Boil-off gas is detrimental to its very low temperature. Also disadvantageously missing at a restart of the fuel supply system or from an energy-converting unit supplied by it Heat to Conditioning the cryogenic fuel. That's why proposed a heater that advantageously with a heat storage may be provided, either in principle for the removed from the cryo-fuel tank cryogenic fuel or at least for the discharged boil-off fuel to provide, said heater also operated electrically and with the electric generated by said thermocouple electrical Energy is supplied at least indirectly. Alternatively or additionally it possible in this context that the cryogenic fuel and / or the boil-off gas leading line is in heat-conducting connection with the combustion device. This thermally conductive contact can advantageously also over said thermocouple are made, thereby providing the of electric energy by the same required temperature difference at Thermocouple is ensured.
Das besagte Thermoelement zur teilweisen Umwandlung der beim Verbrennungs- oder Umwandlungsprozess des Boil-Off-Gases anfallenden Wärme in elektrische Energie ist vorzugsweise ein sog. Seebeck-Element, also ein thermoelektrischer Generator, der im Aufbau praktisch identisch mit den bekannten Peltierelementen ist. Handelsübliche Seebeckelemente erreichen in kompakter Bauweise Wirkungsgrade und somit elektrische Leistungen, die zur Versorgung der hier genannten elektrischen Verbraucher, aber auch weiterer Verbracuher, wie etwa einer Gaswarnanlage, dienen können. Wenn die Verbrennungseinrichtung für das Boil-Off-Gas katalytisch arbeitet, so kann das Seebeckelement auf einfache Weise am Gehäuse des Katalysators vorgesehen sein, da hier die nutzbare Temperaturdifferenz am größten ist bzw. am einfachsten nutzbar ist.The said thermocouple for the partial conversion of the combustion or conversion process of boil-off gas resulting heat into electrical Energy is preferably a so-called Seebeck element, ie a thermoelectric generator, the structure practically identical to the known Peltier elements is. commercial Seebeckelemente achieve in a compact design efficiencies and thus electrical services that are used to supply the here mentioned electrical consumers, but also other Verbracuher, such as a gas warning system, can serve. When the boil-off gas combustion device is catalytic works, so the Seebeckelement can easily on the housing of the Catalyst be provided, since here the usable temperature difference is greatest or easiest to use.
Zu
Sicherstellung, dass kleinste Leckagen aus dem Kryo-Kraftstofftank-System, insbesondere den
Leitungen desselben, nicht zu erwünschten Ansammlungen von gasförmigem Kraftstoff
an unerwünschten
Orten führen
können,
kann eine sog. Nebensystemkapsel vorgesehen sein, die u.a. die den kryogenen
Kraftstoff führenden
Armaturen umhüllt. Diese
Nebensystemkapsel sollte geeignet gespült bzw. belüftet werden, was mittels eines
Gebläses
bewerkstelligt werden kann, das (ebenfalls) über den elektrischen Hilfsenergiespeicher
(und somit zumindest indirekt über
die vom Thermoelement erzeugte elektrische Energie) betreibbar ist.
Analog dem bekannten Stand der Technik (
Kritische Bereiche hinsichtlich möglicher – und sei es auch noch so geringer – Leckagen sind Verbindungsstellen von den kryogenen Kraftstoff führenden Leitungen. Eine solche Verbindungsstelle kann sich auch in der das Boil-Off-Gas in einen der eigentlichen Verbrennungseinrichtung (bspw. in Form eines Katalyten) vorgelagerten saugstrahlpumpenartigen Abschnitt zur Beimengung von Verbrennungsluft führenden Leitung befinden. Sicherheitshalber kann auch dieser Bereich von einer Hüllkapsel umhüllt sein, wobei jedoch dafür Sorge zu tragen ist, dass auch der Innenraum dieser Hüllkapel gespült wird. In besonders einfacher Weise kann dies dadurch erfolgen, dass der Hüllkapsel-Innenraum über einen Wanddurchbruch mit dem genannten saugstrahlpumpenartigen Abschnitt in Verbindung steht, in welchem dann Unterdruck vorliegt, wenn durch die Leitung Boil-Off-Gas geführt wird. Nur dann könnte eine geringe Leckmenge überhaupt anfallen, und diese wird durch diesen Unterdruck nun selbsttätig aus der Hüllkapsel zur Verbrennungseinrichtung hin abgezogen.critical Areas regarding possible - and be it is even lower - leaks are joints leading from the cryogenic fuel Cables. Such a connection point can also be found in the Boil-off gas in one of the actual combustion device (eg in the form of a Katalyten) upstream suction jet pump-like section for admixing leading from combustion air Line are located. For safety's sake, this area can also be of be enveloped by an envelope, but for that Care must be taken to ensure that the interior of this sheath is rinsed. In a particularly simple manner, this can be done by the Shell capsule interior over one Wall opening with said suction jet pump-like section in which there is then negative pressure, if through led the line boil-off gas becomes. Only then could a small amount of leakage at all incurred, and this is now automatically by this negative pressure the shell capsule deducted towards the incinerator.
Eine katalytisch arbeitende Verbrennungseinrichtung enthält üblicherweise einen vom umzuwandelnden Boil-Off-Gas durchströmten Trägerkörper, auf welchen ein geeigneter Katalyt aufgebracht ist. Ähnlich den bekannten Abgaskatalysatoren von Kraftfahrzeugen kann dieser Trägerkörper eine Vielzahl parallel angeordneter Kanäle bspw. in Wabenstruktur aufweisen. Um die Gefahr von Rückzündungen in einer solchen Verbrennungseinrichtung zu reduzieren, kann diesem katalytisch beschichteten Trägerkörper ein weiterer nicht katalytisch beschichteter Trägerkörper (oder ein nicht beschichteter Abschnitt desselben) vorgeschaltet sein, der ebenfalls vom Boil-Off-Gas durchströmt wird und somit quasi eine Flammbarriere darstellt. Die beiden sog. Trägerkörper können dabei eine Baueinheit bilden, d.h. dass ein einziger Trägerkörper lediglich abschnittsweise, nämlich in seinem in Strömungsrichtung hinterem Bereich mit Katalyt-Material beschichtet ist.A Catalytic combustion equipment usually contains a flowed through by the boil-off gas to be converted carrier body, on which a suitable Katalyt is applied. Similar the known exhaust gas catalysts of motor vehicles can this Carrier body one Have a plurality of parallel channels, for example. In honeycomb structure. To the risk of flashbacks in such a combustion device can reduce this catalytically coated carrier body another non-catalytically coated carrier body (or an uncoated Section of the same), which is also from the boil-off gas flows through becomes a quasi-flame barrier. The two so-called. Carrier body can thereby form a structural unit, i. that a single carrier body only in sections, namely in his in the direction of flow Rear area is coated with Katalyt material.
