The Gas Research Inst (GRI), the US Dept of Energy (DOE), and the Southern California Gas Co (SoCal) have joined with the development team of the Inst of Gas Technology (IGT), Combustion Tec Inc (CTI), and Air Products & Chemicals Inc (APCI) and provided support for extension of the oxygen-enriched air staging (OEAS) NOx control technology to natural gas-fired sideport regenerative glass melters. Background and initial test resutls for a single port pair and the complete furnace are presented along with CFD modeling results for OEAS on a signle port pair of the sideport furnace. Modeling results confirm the cpaicity of OEAS to provide significant NOx reduction & CO burnout while maintaining or increasing thermal efficiency & production rate.
