Abstract
Description
Die Erfindung betrifft eine Anordnung zur Erzeugung von Wasser an Bord eines Luftfahrzeuges unter Verwendung von einer oder mehreren Brennstoffzellen, wobei eine teilweise oder vollständige Integration einer Wassererzeugungseinheit in Form von einer oder mehreren Hochtemperatur-Brennstoffzellen in einem Flugzeugtriebwerk derart vorgesehen ist, dass Brennkammern des Flugzeugtriebwerkes ganz oder teilweise durch die Hochtemperatur-Brennstoffzellen ersetzt werden, nach Patent ......... (Patentanmeldung 102 16 710.9-22).The invention relates to an arrangement to produce water on board an aircraft using of one or more fuel cells, one partially or full Integration of a water production unit in the form of a or several high-temperature fuel cells in an aircraft engine is provided such that combustion chambers of the aircraft engine replaced in whole or in part by the high-temperature fuel cells be, according to patent ......... (patent application 102 16 710.9-22).
In der Hauptanmeldung 102 16 710.9-22 ist eine Anordnung mit den oben aufgezeigten Merkmalen beschrieben, die eine optimale Ausnutzung der Brennstoffzellentechnologie und entsprechender Redundanzen für ein Flugzeug gewährleistet und den geforderten Sicherheitsaspekten Rechnung trägt.In the main application 102 16 710.9-22 an arrangement with the features shown above is described, which make optimal use of fuel cell technology and corresponding redundancies for an airplane ensures and takes into account the required safety aspects.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Anordnung der eingangs genannten Art zu schaffen, bei der eine Brennstoffzellen-Gasturbinen-Kombination für den ausschließlichen Betrieb mit Wasserstoff und Luftsauerstoff, als Triebwerk und/oder als Hilfstriebwerk (APU – Auxiliary Power Unit) zur Druckluftversorgung der Kabine und zur Stromerzeugung vorgesehen ist.The invention is therefore the object to create an arrangement of the type mentioned in the introduction, where a fuel cell-gas turbine combination for the exclusive Operation with hydrogen and atmospheric oxygen, as an engine and / or as auxiliary power unit (APU - Auxiliary Power Unit) for supplying compressed air to the cabin and for generating electricity is provided.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass den Hochtemperatur-Brennstoffzellen anodenseitig reiner Wasserstoff und kathodenseitig Luft zugeführt werden, dass den Brennkammern ein Gemisch aus Wasserstoff und Luft zugeführt wird, und dass mindestens die Wasserstoffzufuhr regulierbar oder vollständig abschaltbar ausgeführt ist.The object is achieved in that the high-temperature fuel cells pure hydrogen on the anode side and air is supplied on the cathode side that the combustion chambers are a mixture of hydrogen and air supplied and that at least the hydrogen supply can be regulated or Completely can be switched off is.
Ausgestaltungen der Erfindung sind in den Unteransprüchen 2 bis 26 beschrieben.Embodiments of the invention are in the subclaims 2 to 26 described.
Ebenso wie beim Gegenstand der Hauptanmeldung sollen) mindestens eine, vorzugsweise jedoch mehrere Brennkammern durch eine oder mehrere Hochtemperatur Brennstoffzellen ersetzt werden. Im Unterschied zu dem genannten Gegenstand bleiben jedoch mindestens eine oder mehrere Brennkammern zur Verbrennung eines Wasserstoff-Luft Gemisches erhalten. Die Brennkammern und Hochtemperatur-Brennstoffzellen werden vorzugsweise abwechselnd ringförmig um die Welle bzw. die Wellen der Gasturbine angeordnet.As with the subject of the main application should) at least one, but preferably several combustion chambers replaced by one or more high temperature fuel cells become. In contrast to the object mentioned remain at least one or more combustion chambers for the combustion of a Preserved hydrogen-air mixture. The combustion chambers and high temperature fuel cells are preferably alternately annular around the shaft or Shafts of the gas turbine arranged.
Die Brennkammern dienen dem Start der Gasturbine und der Hochtemperatur-Brennstoffzellen sowie einer kurzzeitigen Erhöhung des Luftdurchsatzes der Gasturbine, beispielsweise zum Start eines Luftfahrzeuges. Im Dauerbetrieb wird ausschließlich die thermische Energie der Hochtemperatur-Brennstoffzelle für die Erzeugung des Luftdurchsatzes benutzt. Die Wassererzeugung findet anodenseitig, d.h. wasserstoffseitig in der Hochtemperatur-Brennstoffzelle statt. Dieses sogenannte Anoden-Abgas besteht bei vollständiger Umsetzung des eingetragenen Wasserstoffs zu 100% aus Wasserdampf (Heißdampf). Dieser Heißdampf wird durch eine Turbine geleitet, wo er durch Expansion abgekühlt wird und damit thermische Energie in Rotationsenergie der Turbinenwelle umgewandelt wird. Diese Rotationsenergie wird in einem Kompressor dazu verwendet, den nötigen wasserstoffseitigen Vordruck für die Hochtemperatur-Brennstoffzelle zu erzeugen.The combustion chambers are used for the start the gas turbine and the high-temperature fuel cells as well as one short-term increase the air throughput of the gas turbine, for example at the start of a Aircraft. Only the thermal energy is used in continuous operation the high-temperature fuel cell for the generation of air flow used. Water production takes place on the anode side, i.e. hydrogen side in the high temperature fuel cell. This so-called anode exhaust gas exists at complete 100% conversion of the hydrogen introduced from water vapor (Superheated steam). This hot steam is passed through a turbine where it is cooled by expansion and thus thermal energy in rotational energy of the turbine shaft is converted. This rotational energy is in a compressor used the necessary Hydrogen side form for to produce the high temperature fuel cell.
In einer weiteren Prozessstufe wird der Wasserdampf schließlich auskondensiert. Man erhält reines H2O, also destilliertes Wasser. Dieses Wasser wird den unterschiedlichen Verbrauchern zugeführt bzw. über eine Aufsalzungseinheit zu Trinkwasser aufbereitet. Anfallendes Grauwasser wird in einen Sammelbehälter aufgefangen, ebenso wie der beim Dehydrieren von Schwarzwasser abgeführte Wasseranteil. Die Wassermengen werden in einem mit der Abwärme des Wasser-Kondensationsprozesses betriebenen Verdampfer verdampft und zusammen mit dem nicht zur Wassergewinnung benötigten Dampfanteil aus dem Anodenabgas der Hochtemperatur-Brennstoffzelle vor der zweiten Turbinenstufe der Gasturbine zugeführt. Luftseitig wird über einen sogenannten Fan Außenluft und/oder Kabinenabluft angesaugt. Dieser Fan wird im Normalbetrieb durch die zweite Turbinenstufe angetrieben, beim Startvorgang durch einen Elektromotor. Die durch den Fan geleitete Luft wird in einem nachgeschalteten Kompressor zunächst vorverdichtet und dann in einem weiteren Kompressor für die Brennkammern und die Luftseite der Hochtemperatur-Brennstoffzelle weiter verdichtet. Die über die Brennkammern bzw. die Hochtemperatur Brennstoffzelle eingetragene thermische Energie treibt dann zunächst die erste Turbinenstufe an und nach der oben beschriebenen Zuführung von Grauwasser in den heißen Abluftstrom die 2. Turbinenstufe. Die Anzahl der Kompressor- und Turbinenstufen sowie die Anzahl der Brennkammern und der Hochtemperatur-Brennstoffzellen lässt sich je nach Anforderung beliebig für unterschiedliche Typen variieren.In a further process step, the water vapor is finally condensed out. Pure H 2 O, ie distilled water, is obtained. This water is supplied to the different consumers or processed into drinking water via a salting unit. Any gray water that arises is collected in a collection container, as is the amount of water removed when black water is dehydrated. The water quantities are evaporated in an evaporator operated with the waste heat from the water condensation process and, together with the steam portion not required for water extraction, are fed from the anode exhaust gas to the high-temperature fuel cell before the second turbine stage of the gas turbine. On the air side, outside air and / or cabin exhaust air is drawn in via a so-called fan. This fan is driven by the second turbine stage in normal operation, and by an electric motor during the starting process. The air guided by the fan is first pre-compressed in a downstream compressor and then further compressed in a further compressor for the combustion chambers and the air side of the high-temperature fuel cell. The thermal energy introduced via the combustion chambers or the high-temperature fuel cell then first drives the first turbine stage and, after the above-described supply of gray water to the hot exhaust air stream, the second turbine stage. The number of compressor and turbine stages as well as the number of combustion chambers and high-temperature fuel cells can be varied as required for different types.
