Tuesday, 23 April, 2013 - Pre-Conference Seminars

8:00 Pre-Conference Seminar Registration

9:00-12:00 Seminar I: Principles of Cokemaking (additional fee required)
Instructor: Ingomar Koehler, Consultant, PROCOMCO, Germany

The seminar is focused on everyone who wants a competitive introduction in the basics of the coke making processes and will particularly benefit steel and coke executives, blast furnace, foundry and metallurgical engineers, operation managers, marketing and purchasing executives. An in-depth review of all aspects of by-product and heat recovery cokemaking will be provided including personal requirements, coal input, coke quality, and gas.

The seminar starts with a historical review of the coke making technology beginning with the production of charcoal in the 1700s used in the blast furnaces instead of coke up to the last highly sophisticated plant of today. The development of the flame oven to the by-product plant covers the different types focused on their heating systems based on the desire of the location as stand-alone plants or part of an integrated steel mill. What the iron ore for the blast furnace is the coal for the coke plant. The advantages and disadvantages of the revival back to heat recovery ovens will be discussed with regard to usable coal spectra and discrepancies in carbon dioxide emissions. The differences of the wet quenching system and dry cooling system will be outlined regarding to emissions and energy savings. A summary of recent developments and trends gives an outlook to the future of coke making technologies.
