Stromsparende und umweltschonende Technik auf Flüssen

摘要

Even if the new cabin river cruiser ?A-Rosa Silva? is equipped only with a conventional diesel-mechanical propulsion system the total energy concept of the ship is characterised by saving fuel and reducing emissions from the very beginning. Looking at the electric power balance of a cabin river cruiser the air conditioning systems come second. Thus the shipowner investigated all heat exchange processes on board to reduce possible losses, for instance, using LED lights saving a lot of electric power and reducing the demand of air conditioning. A-Rosa Flussschiff used them for the first time at the ?Silva?. As an innovation on board inland waterway vessels a so-called heat wheel is used for heat recovery from the warm cabin air. The cooling water of the genset engines is used for warm water treatment. In addition, just for testing, a heat recovery system was installed to make use of the thermal energy of the exhaust gas and replace the last boiler on board.rnThe main propulsion system of the ?Silva? consists of four Volvo Penta D12 engines driving Schottel rudder propellers with a power of 331 kW each. In addition there is a Schottel pump jet which ensures the emergency speed of 6 km/h. For electric power supply there are three generating sets with a total output of 1,134 kW.%Abgesehen von der Hauptantriebsanlage - so sie diesel-elektrisch ausgeführt ist - sind die Klimaanlagen von Kabinenschiffen die gr??ten Stromverbraucher an Bord. So liegt es nahe, alle Details dieser Anlagen genau zu prüfen, ob und in welchem Ma?e sich mithilfe einer anderen Einbindung in eine Gesamtanlage Einsparungen verwirklichen lassen.
