Coke Oven Batteries, Zollverein Coking Plant

The 600 meter long coke oven batteries with 304 narrow coke ovens characterize the face of the
so-called "black side" of the coking plant.

Large number of coke oven batteries, which have been significantly expanded over the course of the productive years

The eight batteries with 192 furnaces were built within three years, starting from the east: (batteries 7 and 8: 1958; batteries 4-6: 1959; battery 3: 1960; batteries 1 and 2: 1961).
They were compound ovens from the Still company, which could be fired with the gas from the generator system operated until 1975. Dimensions: height 6.0 m, average chamber width 45 cm, chamber length 12.77 m. Usable volume 32.8 m3 for approx. 28 t wet coal. Batteries 1 and 2 were renewed by Krupp-Koppers in 1980, battery 3 in 1979, battery 8 in 1980, battery 4 in 1982 and battery 5 in 1987 by Still. Batteries 6 and 7 have been preserved in their original condition.
Each battery consists of 24 furnaces. The battery end heads are made of reinforced concrete. Between the kiln doors there are tie stands made of double-T profiles, which reach from the bottom of the regenerators to the kiln roof. In the case of the renewed batteries, there is a heavily dimensioned T-beam between the oven doors; in the original batteries, two weaker double T-beams are coupled to form an anchor stand. Just below the furnace ceiling, the anchor stands are connected with anchor cables, reaching across the furnaces. On the same level, five longitudinal anchors between the battery end heads stabilize the construction.
The typical construction of Still coke ovens includes heavy frame-like trusses, which pierce the outer walls of the master tunnels with their inclined supports. These angular trusses reach under the ceiling of the master passages up to the anchor stands and then continue as tie rods between regenerators and furnaces, i.e. reaching across underneath the furnaces.Source: kuladig.de/Object View/P-WBuschmann-20090714-0022
