As it is not easy to extract quantitative data from multiphase flow experiments, the validation of numerical models needs some creativity and quite often one has to leave the established methods and find some new approaches on qualitative or pseudo quantitative data processing methods. Thus, we developed a strong focus on image and signal processing of experimental data, and over the last years we also managed to transfer some of these methods to real plant data. Some examples can be found below and in our annual reports.

The raceway areas in a blast furnace are highly dynamic structures and are subject to collapsing from time to time because of the downward movement of the burden. These events can result in reduced gas throughput and incomplete burning of fuel substitutes like pulverized coal. Due to the harsh environment in a blast furnace there is only very few plant data available about the process.
