Abstract

The invention relates to an energy recovery device designed as a device disposed in freely flowing bodies of water for generating electrical energy. An axial flow-through channel is thereby designed in a housing in the manner of a venturi nozzle, having a propeller turbine connected to a generator disposed at the narrowing cross section thereof, wherein a nozzle-shaped inlet housing is placed upstream of the propeller and a suction tube comprising a diffuser-like outlet is placed downstream thereof, wherein the diameter of an entrance area of the inlet housing is greater than a diameter of the propeller. The suction tube comprises an inner contour configured to be free of separation over the length thereof, wherein an outlet area of the suction tube comprises a width in the horizontal plane that is greater than a height measurable in the vertical direction, and the outlet area corresponds to 3 to 5 times the area of the propeller area (AP = 3 to 5).
