The Kaiserstühl plant (Kaiser Chair III) was a coking plant in Dortmund. It was put into operation on 1 December 1992 after five years of planning and construction on the site of Westfalenhütte the Thyssen Krupp Stahl AG (former owner Hoesch AG) as a modern coking plant in Europe. On 12 December 2000 it was shut down after 8 years and 12 days from the operation time became necessary adaptation to the coking plant capacity due to the closure of the Thyssen blast furnace in Dortmund.

After the amendment of the Technical Instructions on Air Quality Control (TA Luft ) in 1986 summarized the then- Ruhr coal AG 's decision to build a new coking plant in Dortmund and at the same time for subsequent decommissioning of the until then existing Dortmunder Hansa coking plant and the Kaiserstühl plant II total investment accounted for approximately DM 1.2 billion, 25% of which alone accounted for environmental protection measures.

Decommissioning and dismantling

The changes on the customer side, the acquisition of Dortmund Hoesch AG by competitors Krupp and the subsequent merger with Thyssen Thyssen Krupp, no more customers were locally available close for their product coke; ThyssenKrupp moved all activities of the so-called liquid phase to the Rhine after Duisburg, due to more favorable conditions of transport ( maritime and port services).

It was decided that rather new coke plant to shut down, which occurred in 2003. The coking plant was sold to the Chinese mining company Yanzhou Coal Mining in Shandong Province and built near Zaozhuang again, because the technical facilities were standard of coking technology. The first coke was pushed on 28 June 2006 with very large problems.

In the meantime, proved the decision, the coking plant shut down after only a short operation, as well as economically questionable: The steel boom in China it became more difficult in the global market starting in 2003, to get coke for iron smelting. The coke price rose dramatically, far stronger than the steel prices.

The dismantling of the coking plant was accompanied by a German film crew. There was the documentary "Losers and Winners", which took place in 2007 in the cinemas and received several international and German prices. In addition, Stefan Willeke wrote for " The Time " a documentary about the crash, which was in 2005 awarded the Egon Erwin Kisch Prize.

On October 28, 2007 at 11:08 clock, the two still existing 165 meter high chimneys were blown up. Here, one of the fireplaces did not fall into the prepared bed, but beat with a deviation of 70 degrees in the old building stock of the coking plant.
