Studying material science, ceramics, in Erlangen (Prof. Oel, Prof. Schaeffer) Since 1988 working for the Research Association of the German Glass Industry (HVG): main subjects of daily work besides others in the field of glass melting technology: • non destructive testing (of refractories) • corrosion behaviour of molybdenum electrodes • refractories • investigations with spectral radiometers (flames, glass) • energy consumption of glass furnaces; heat balances • combustion technology • LIBS • temperature measurement techniques






Gas Quality and Glass Quality – The impact of fuel gas quality on the glass production process (BMWi Research Number 03ET1296 A to D)

For years the glass industry in Germany has realized that the natural gas delivered in the grid is not as constant in its quality as the industry had grown accustomed to in the last decades. These variations in the quality of the fuel gas influence different steps of the glass production process and have already led to problems in recent years. Depending on how closely some process steps are operated to their technical limits, the glass melting furnace, the feeders, the forming process and the annealing process, respectively can be the source of decreased output in glass production. The research project “GasqualitaetGlas” aims to document the local fluctuations of gas quality in different locations in Germany, usingdifferent measurement techniques. This will also serve to test and evaluate different measuring methods with regads to their applicability in the glass industry. To compensate for the fluctuations and variations in gas quality, the control tools for the glass melting process have to be adapted. New concepts will be tested in the second part of the project.
