Abstract
Der Kalk-trocknungs-Krümmer zur latenten Speicherung der Abgaswärme von Dieselmotoren dadurch gekennzeichnet das zwei Schalen-hälften, von oben und von unten über die Abgaskanäle (oft Auspuffkümmer genannt) zusammengefügt werden.The lime-drying manifold for the latent storage of the exhaust heat of diesel engines characterized in that two shell halves, from above and below via the exhaust ducts (often called Auspuffkümmer) are joined together.
Description
System einer Speicherung von latenter Wärme durch Nutzung von CaO Calciumoxid. Durch zufuhr von Wasser H2O, auch als Wasserdampf, wird das CaO zu Ca(OH)2 Calciumhydroxid. Der exotherme Vorgang dabei ist bekannt und in zahlreichen Patenten genutzt. Zur Speicherung der Wärme einer externen Wärmequelle ist ein geeigneter Wärmeübergang nötig. Dabei wird dem Ca(OH)2 das Wasser entzogen, Dehydriert. Es entsteht wieder CaO. Der Zyklus kann erneut durchlaufen werden. Dies wird auch in der Patentschrift:
dargestellt.System of storage of latent heat by use of CaO calcium oxide. By supplying water H2O, also called water vapor, the CaO becomes Ca (OH) 2 calcium hydroxide. The exothermic process is known and used in numerous patents. For storing the heat of an external heat source, a suitable heat transfer is necessary. The Ca (OH) 2 is deprived of water, dehydrated. It creates CaO again. The cycle can be run again. This is also stated in the patent:
shown.
Als Quelle für die Wärmeenergie soll die Abgase eines oder mehrerer Dieselmotoren dienen. Besonders geeignet sind dafür die Schiffsdiesel von Seeschiffen.The source of heat energy is the exhaust gases from one or more diesel engines. Particularly suitable for this are the marine diesels of seagoing vessels.
Wegen der Vielfalt an an sehr verschiedenen Motortypen und Herstellern bedingte Ausführung der Abgaskanäle ist eine Zeichnung irritierend.Due to the variety of on very different engine types and manufacturers conditional execution of the exhaust ducts is a drawing irritating.
Meßeinrichtungen an den Behältnissen erlauben es zu erkennen, wann das enthaltene Calciumhydroxid zu Calciumoxid gewandelt wurde.Measuring devices on the containers allow to detect when the contained calcium hydroxide has been converted to calcium oxide.
Die Behältnisse mit dem CaO werden dann im Hafen als latenter Wärmespeicher einer Wärmelieferungsstelle zur Verfügung gestellt.The containers with the CaO are then made available in the harbor as a latent heat storage of a heat delivery point.
Dabei sollten die Erkenntnisse des Forschungs-Projektes BERTI des BMWi zur Speicherung von Wärme in Kalk genutzt werden. Insbesondere die zur Beförderung des Kalks und den Druckverhältnissen während der Umwandlungen zu nutzen.The findings of the research project BERTI of the BMWi for the storage of heat in lime should be used. In particular, to use those for the transport of lime and the pressure conditions during conversions.
Ablauf des Zyklus für die latente Wärmespeicherung,
Calciumhydroxid wird in einem Behältnis von der Wärmelieferungsstelle zum Hafen (Seeschiff oder Binnenhafen) transportiert. Solch eine Wärmelieferungsstelle könnte ein Fernheizkraftwerk oder eine kleinere Anlage zur Lieferung von Wärme als Warmwasser sein. An Bord der Schiffe wird das Calciumhydroxid über Rohre den Kalk-trocknungs-Krümmern an den Abgaskanälen der Schiffsdiesel zugeführt. Während der Betriebszeit der Motore findet dann der Trocknungsvorgang (dehydrierung) statt.Cycle of the latent heat storage cycle,
Calcium hydroxide is transported in a container from the heat supply point to the port (ship or inland port). Such a heat delivery center could be a district heating plant or a smaller plant for supplying heat as hot water. On board the ships, the calcium hydroxide is supplied via pipes to the lime-drying manifolds on the exhaust ducts of the marine diesel. During the operating time of the motors then the drying process (dehydration) takes place.
