Topics for Theses
The department offers topics for Bachelor’s and Master’s theses as well as student research projects. If noted in the respective examination regulations, the thesis can be written in either German or English in agreement with the examiner.
In continuous annealing lines, radiant tubes are used for indirect heating. To reduce direct CO₂ emissions from combustion in these systems, the substitution of natural gas by hydrogen is investigated at the department. In radiant heating tubes in a double‑P configuration, a significant proportion of the flue gas is recirculated to dilute and cool the reaction zone and to reduce environmentally harmful NOx emissions. As part of this work, measurements of recirculation under cold-flow conditions are carried out. The results are used to validate the numerical mesh and turbulence modelling in a CFD simulation.
The steel industry is constantly evolving towards a circular economy and carbon neutrality. The aim of this work is to valorise iron-rich residues (slag, dust, sludge) by producing self-reducing agglomerates using sustainable biochar. Direct charging of fine-grained residues in smelting furnaces is only feasible to a limited extent for technical reasons. Stable agglomerates are required that can withstand the mechanical stresses of transport and furnace charging.
