CFD modelling of the off-gas system of HIsarna iron making process. Part 1: model development using detailed reaction mechanism for post-combustion of CO–H2 mixture and carbon particles

Autor: Ashkan Hosseini, Vinod Dhiman, Koen Meijer, Christiaan Zeilstra, Johannes Hage, Tim Peeters, Erik Offerman, Yongxiang Yang

Publikováno v: Ironmaking & Steelmaking: processes, products and applications, 49(8)

The HIsarna process is a new and breakthrough smelting reduction process for hot metal (liquid iron) production from iron ores and coal directly fed into the reactor. The flue gas from the main reactor enters the off-gas system containing small amoun

Thermodynamic analysis of zinc ferrite (ZnFe2O4) formation inside the HIsarna off-gas system

Autor: Ashkan Hosseini, Elmira Moosavi-Khoonsari, Koen Meijer, Johannes Hage, Tim Peeters, Erik Offerman, Yongxiang Yang

Publikováno v: Ironmaking & Steelmaking: processes, products and applications

HIsarna reactor is characterized by a high raw materials versatility and is therefore attractive for processing secondary iron sources. Among the materials that can be recycled through HIsarna, zinc-bearing material has drawn a special attention. Bas

Publikováno v: Ironmaking & Steelmaking: processes, products and applications, 48 (2021)(4)

Physicochemical behaviour of the pellets, sinters and its mixture (60% pellets: 40% sinter) is investigated by a series of smelting and quenching experiments. For all ferrous raw-material beds, three distinct stages of bed shrinkage occur due to indi
