Optimization of burners in oxygen-gas fired glass furnace
conference paper
The energy efficiency performance, production stability and emissions of oxygen-fired glass furnaces are influenced by the type of burner, burner nozzle sizes, burner positions, burner settings, oxygen-gas ratios and the fuel distribution among all the burners. These parameters have been optimized for a 300 tpd (metric tons per day glass pull) oxygen-gas fired container glass furnace in order to improve the heat flux into the glass and to improve convective flows in the glass melting tank. An objective of these adaptations was a reduction of foam formation and decrease of evaporation from the melt. Energy consumption and emission of NOx and dust were measured before, during and after the modifications in these combustion parameters. Glass quality parameters such as seed count and glass color were monitored daily and were kept in very tight ranges. The paper describes the combination of burner optimization measures that have been applied and the results concerning energy consumption reductions, emission changes and stabilizing glass quality.
