Kaiser Franz Furnace Blowing Engine






This is a twin beam blowing engine which formerly served the Kaiser Franz-Hochofen (Kaiser Franz blast furnace) in Austria, now preserved in Vienna Technical Museum.
It was constructed in 1847 by the staatlichen Eisengiesserei (Austrian State Iron Foundry) in Gusswerk, near Mariazell (Styria).
It absorbed 15 HP at 12 rpm. It is not clear whether it was driven by a steam engine or a waterwheel.
It was taken out of service in 1901.
