Installation of a 145-MMBtu/Hour Oxyfuel Firing System on the No. 2 Reheat Furnace at ArcelorMittal’s 84-Inch Hot Strip Mill
Erick Black, process manager, and Frank Erfurth (former process manager), ArcelorMittal Steel USA, 84-inch hot strip mill, East Chicago, Ind. (erick.black@arcelormittal.com); Greg Kitko, president, GTK Flow Analysis LLC, Coraopolis, Pa. (gkitko@gtkflow.com); Mario Hernandez, sales engineer — NAIG North Region/NAIG North Business Development, James Kelly, senior development associate — R&D Ind. Food & Water Appl./Metals, Lee Rosen, senior manager — oxygen transport membrane commercial development, and Kelly Tian, development associate II — R&D Ind. Food & Water Appl./Combustion, Praxair Inc., Tonawanda, N.Y. (mario_hernandez@praxair.com, james_kelly@praxair.com, lee_rosen@praxair.com, kelly_tian@praxair.com)
Praxair’s DOC technology was implemented on the No. 2 reheat furnace at Indiana Harbor. CFD analysis was performed to identify the cause of the difference in performance compared to the No. 3 furnace. A modified burner design was developed, delivering significant fuel savings with no impact on other critical parameters. |

Improved SVC Performance for Flicker Mitigation of an Electric Arc Furnace
Rolf Grünbaum (top left), Tomas Gustafsson (top right) and Jean-Philippe Hasler (bottom left), ABB AB, Vasteras, Sweden (rolf.grunbaum@se.abb.com, tomas.b.gustafsson@se.abb.com, jean-philippe.hasler@se.abb.com); Anders Persson, ABB Inc., Saint Laurent, Que. Canada (anders.j.persson@us.abb.com); and Tom Dietrich (bottom right), Dietrich Consulting Ltd., Leader, Sask., Canada (tom.dietrich@sasktel.net)
A traditional SVC is effective as a flicker mitigator only up to a reduction factor of 1.5–2. Due to a novel approach to sizing the SVC, it is now possible to demonstrate a flicker reduction factor of 2.5. This paper highlights the application of the approach in a steel plant in Canada. |
