Post Combustion Chamber of HIsarna Off-Gas System
CFD modelling of the off-gas system HIsarna iron making process part 2
Reflux chamber geometry modification and effects on flow behaviour
A three-dimensional computational fluid dynamics (CFD) model for the HIsarna off-gas system is set up and validated by real plant data. In the model detailed reaction mechanism and kinetic data for post-combustion of CO-H2 mixture and carbon particles are incorporated. The res ...
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
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 amounts of H2, CO and ...
Off-Gas System Scale-Up of HIsarna Iron-Making Process
A CFD-Based Approach
HIsarna is a novel ironmaking process with great raw materials versatility that is attractive for various secondary resources. Among the materials that can be recycled, there is steel scrap which is fed to the furnace bath through an inclined chute. The velocity distribution o ...
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. Based on the plant data, once ...
