THE YEAR-BOOK OF THE COKE OVEN - Coke-oven-managers.org

The first development of PROven ® - was carried out by the company DMT
in Essen, Germany 6 . In cooperation with Uhde the system was developed
for technical application. In total it took about 10 years until the first coke
oven batteries without any additional provisions, such as high pressure
water aspiration have been installed at the Schwelgern coking plant in
Germany. The history of the development is shown in table 2, indicating
its technical maturity.

Table 2 10 years development of the PROven ® - system
After the commissioning of PROven ® at Schwelgern many other
applications have been realized world wide, which is also shown in table 3.
In total 33 batteries comprising more then 2000 ovens are under contract
with a different status of realization. Likewise, existing batteries under
operation have been and, respectively, will be equipped with this system.
The contract for the battery in the USA is on hold, resulting from influences
of the crisis. In this connection it should be mentioned, that the EPA has
acknowledged this technology as an alternative to the heat-recovery type of
ovens due to its convincing environmental features.
