As is well known, the Kaiserstuhl coking plant in Dortmund, Germany was shut down 20 years ago, after only eight years of operation, and sold to China.
There, in the mining province of Shandong, the plant was rebuilt and put back into operation in 2006.
Rumor has it (e.g., Peter Liszio in “Der Kokshochofen”, 2015) that it was already shut down again in 2012 after major start-up problems.
That seemed a bit surprising to me. So I did a little research on this plant and indeed Kaiserstuhl still exists. The plant was even modernized again in 2019.
And as before, the coke dry cooling device is still more of a decorative nature.
