The Heilbronn hydropower plant is a run-of-river power plant on the Neckar in Heilbronn and, with an expansion capacity of 1.7 MW , is a small hydropower plant . The building at Hospitalgrün 1 near the Heilbronn ice rink is a listed building .
The hydropower plant built in 1956 and a small older hydropower plant next to it go to the municipal sawmill from the 15th / 16th centuries. Century back.
history
The area between Bleichinsel / Hospitalgrün and Hefenweiler was the traditional Heilbronn mill district. The city of Heilbronn used the hydropower of the Neckar, which was dammed up due to the Neckar privilege of 1333, in various municipal mills. At that time, the Neckar was channeled through dams into waterways in order to strengthen the current and to be able to drive more and more water wheels . The name of the dam school located nearby is derived from it. In 1451 Hans Anse from Langenau received an inheritance to build a sawmill on the compartment near the Lohmühle. In 1558 the town acquired the sawmill, which was then leased to tenants until the late 19th century.
The industrialization of the city started from the Mühlenviertel. As early as 1820, factories that used water power were located in the Mühlenviertel. Some of these were new buildings and some were older mill properties acquired by the city. The manufacturers Rauch , Schaeuffelen , Hauber, Hagenbucher and Knorr operated water wheels . Schaeuffelen had an artesian well drilled to ensure that the waterwheels were also powered in winter . Even in the harshest winter, the 12 degree warm well water stopped the waterways from icing up.
From 1869 Friedrich Schwarzkopf was the last tenant of the municipal sawmill. When he moved to the Uhlandsche saw mill in Nordheim in 1875, the municipal sawing operation ended. The water power of the old sawmill was used from 1898 by the paper mill Gebr. Rauch to generate electricity by means of turbines and generators. In 1910 or 1922 the first hydroelectric power station was built on this site. The two Francis turbines were manufactured by Voith . They have vertical waves , which are connected to a horizontal wave, so they only need a common regulator .
The "19th century industrial area" in Heilbronn between Hospitalgrün and Hefenweiler was destroyed in the air raid on December 4, 1944 . Only the small hydroelectric power station and the Hagenbucher remained. Portland-Zementwerke AG in Lauffen am Neckar , the forerunner of ZEAG, acquired all of the previously shared Heilbronn water rights after the Second World War and commissioned the new construction in the 1950s at the site of the large weir that had previously regulated the inflow to the mills another power plant that made use of the experience of past centuries. Just as waterways were once built to increase the current, some of the river's side canals were leveled with rubble. This increased the current on the remaining arm of the river, where the river hydropower plant was built, the turbines of which are driven by the Neckar water. Two Kaplan turbines manufactured by Escher-Wyss work in the new hydropower plant . The turbines do not have a common controller as in the old hydropower plant, but in this case have two controllers that double control the turbines. The generators and switching devices were supplied by Siemens-Schuckert . The mechanical engineering crane was supplied by J. Wolff & Co.
description
The power plant was built on behalf of ZEAG according to plans by Emil Burkhardt and Paul Barth in the modern style in 1955/1956. The concrete building is structured vertically with pillars that serve as architectural supports or abutments (on walls) for the projecting cornice . The spaces in between were provided with ocher-colored clinker bricks.
