Advanced operation support system for redox control
conference paper
TNO Glass Group has developed a Glass Process Simulator (shortly GPS) to supply operators and glass technologists with the maximum amount of relevant information for optimal furnace operation. In addition to furnace temperatures as measured by thermocouples, GPS provides online information on redox, glass color, emissions, and the total flow and temperature distribution in the furnace. Because the simulation model GPS is approximately 10 times faster than real time, GPS provides information on the future state of the furnace as function of changes in process settings, batch and melt properties, and external process disturbances. Combination of GPS with special developed inline redox sensors enables the GPS-users to simulate the effect of redox changes at the entrance of the furnace on both the glass melting process and product quality. Next, with GPS (scenarios for) process setting and redox state adaptations to react fast and accurate on the redox disturbances at the entrance of the glass furnace can be determined. This paper shows how GPS can be used, in combination with information from inline redox sensors, to control the color of container glass.
