The thermal treatment of bulk materials is often carried out on a very large scale, e.g. for clinker firing or the processing of fine iron ore. This requires a correspondingly large amount of energy. In the future, more efficient kiln systems will be needed to significantly improve the CO2 balance. When designing kiln systems for bulk material treatment, there is a lack of reliable material data for the material to be heated during processing. The simulation models for heat transfer in industrial furnaces also require experimental validation so that reliable forecasts can be made for plant planning
The aim of this sub-project was to develop new measurement methods that can be used to determine the thermal properties of bulk materials during thermal treatment. These methods should also be applicable for the technically particularly important coarse-grained bulk materials. In addition, methods were to be developed to enable the experimental validation of simulation calculations for heat transfer by conduction, convection and radiation.
