The Stadtgarten - Inatura small hydropower plant is a semi-underground small hydropower plant (demonstration power plant) located in Dornbirn , Vorarlberg , Austria , in the Sägen parcel, in the Markt district, and one of several power plants on the Müllerbach .
history
The small hydropower plant Stadtgarten - Inatura is operated on the site of the former Rüsch works , now the natural history museum Inatura .
The Stadtgarten power plant on Müllerbach is one of a dozen former power plants and is currently one of the last of the still active ones (see also Forach power plant ). The Rüschwerke power plant (named after the company of the same name) was already at the same location and was also located at about river kilometers 2.90. It was used to generate electrical energy with a turbine and a generator with 23.40 kW. The license for the original power plant at the Rüschwerke expired on January 15, 1991.
Power plant
The entire small hydropower plant is arranged outdoors. The maintenance of the power plant is the responsibility of the waterworks of the city of Dornbirn. The hydropower plant is designed as a show power plant and is freely accessible during Inatura's opening hours. The power plant is intended to enable and ensure a glimpse into the industrial history of the city of Dornbirn.
Electrotechnical data
The generator is a three-phase asynchronous machine from ABB with a maximum output of 22 kW at 400 V (36 A ) at 980 / min and an annual output of 40,000 to 60,000 kWh.
Hydraulic data
The water for the power plant is taken from the Müllerbach, which can have different water flow depending on the season and with regard to the amount of residual water in the Dornbirner Ach . In the area of the Stadtgarten power plant, the Müllerbach carries usable around 1850 liters / second.
The energy of the water is converted by a Zuppinger water wheel . The water wheel has a diameter of 5.5 meters, turns 5.5 times a minute, and has 36 wooden shovels. The water enters 0.5 meters below the shaft of the wheel and transfers its power directly to the blades of the water wheel.
transmission
In order to bring the slowly running waterwheel to the nominal speed of the asynchronous generator, a gear (PIV company) is interposed and the speed is brought from a maximum of 5.5 / min to 980 / min (generator) (transmission ratio 1: 92.7).
