The decreasing and fluctuating quality of raw materials and the aim to maximise PCI and decrease coke rates force European blast furnaces to operate closer to operational limits. High stack permeability and stable gas distribution become most important. However, the analysis and control of the stack processes is difficult: Hundreds of measurement values are available, but they are distributed around the blast furnace shell and just show indirect information from the outside instead of the real internal process. New measurement techniques deliver very fast, full 2D information of the top (acoustical gas temperature, burden profile radar), but they have not been investigated by research. Instead, the operators are overcharged with even more separate measurement data. No overall process information is available to decide about control actions. The main idea of StackMonitor is to establish a new approach of data processing which couples statistical and kinetic process models with several online measurements. To achieve this aim, online tools for process monitoring, analysis and control are developed and validated.
