Abstract: Cruise control for glass furnaces: Automated furnace control and batch monitoring systems

Furnaces are the heart of each glass factory, operating continuously to keep production running 24/7. At temperatures around 1,500°C, raw materials are transformed into a viscous melt. The energy required for this chemical transformation and heating is typically provided by fossil fuels like natural gas, oil, and sometimes pet coke. Additionally, electric power supplied via electrodes directly into the melt can accelerate the melting process and reduce energy consumption.

Depending on production planning, availability of cullet, and energy supply and costs, furnace operators must control the energy input to ensure stable furnace temperatures. However, the slow response times of the melter to changes in energy input challenge operators to find efficient melting conditions.

Glass Service offers a model-based predictive control software, “Expert System ES III™” to the glass industry to automate furnace control and address these slow response times. The software analyzes past and current production data to determine the optimal energy settings for stabilizing melting temperatures. By stabilizing the melting temperatures, the software helps reduce wasteful energy usage and lower energy costs.

Additional information about the glass level, waste gas composition, or batch coverage from our AI batch monitoring system can be integrated into the Expert System ES III™ furnace control. This integration further enhances the control behavior, optimizing furnace operations and improving overall efficiency.
