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

comprising 140 ovens and prepared for a production of 0.9 mill t/year,
based on a coal compacting technology developed by Uhde. In this case,
too, UCA has placed an order to the German technology supplier Uhde
Dortmund. Certain engineering packages have been finished and the
delivered equipment has been taken on stock. Further progress is still open.
However the increasing production figures for steel worldwide are a strong
indication that in the field of new investment for coking plants, too, a
positive market can be expected. Likewise, the coke price has shown an
increasing trend by the beginning of 2010.
Summary and Outlook
Before the economic crisis, accompanied by critical developments in the
iron and steel industry, conditions for new investments world wide, and in
the field of coke making, too, were excellent. Many new plants have been
installed either as substitutions of existing old facilities or as extension
projects covering the increasing demand for steel, hot metal and
consequently coke. Long lasting work of development for the coke making
technologies could be materialised at many places in the world, especially
in China and in the rest of Asia. Efforts for optimizing specific cost for
investment and operation can be covered by installing batteries with highcapacity
ovens. Batteries of this type have been installed for a total
production of approximately 20 million t/year since 2003. Likewise, the
environmental situation will be improved by the operation of high capacity
ovens, since for a certain coke production per year less charging- and
pushing cycles have to be carried out. In addition this takes a positive
effect on the lifetime to be expected for these production units. A big jump
forward in terms of environmental optimisation was realised by the
development of a single chamber pressure control system, called PROven ® ,
which brings the fugitive and visible emissions of a coke oven battery down
to almost zero, including charging emissions. The development of this
system within a period of 10 years stands for a technical mature technology.
Its application on more than 2000 ovens proves its acceptance wide.
