Caption | In the foreground: auxiliary steam engine, left: Flywheel and compressor, right: Drive steam cylinder. The compressed air generated by the compressor was used to set the heavy machines with their large generator wheels in motion. Steam could not be used to start these machines cold, because the steam would immediately condense in the cold cylinders. |
Caption (German) | Im Vordergrund: Hilfsdampfmaschine, links: Schwungrad und Kompressor, rechts: Antriebsdampfzylinder. Mit der Druckluft, die der Kompressor erzeugte, wurden die schweren Maschinen mit ihren grossen Generatorrädern in Bewegung gesetzt. Mit Dampf konnten diese Maschinen nicht kalt gestartet werden, denn der Dampf würde in den kalten Zylindern sofort kondensieren. |
