Summary

A novel glass melting furnace has been designed to meet pollutant emission limits without add-on controls and without sacrificing melting or energy performance. This paper reviews the design concept which combines recuperative air and fuel preheat, cullet preheat, batch preheat, and deep refining. Operating results for the first eighteen months of operation, including emission and fuel performance data, are presented.

In summary, the LoNOx™ furnace has demonstrated that the melting process can be modified to emit very low NOx levels, while achieving outstanding melting and energy performance. We believe additional experience will prove the concept to be an economically and environmentally attractive alternative for glass manufacture. The culletpreheater developed as a part of the LoNOx™ system has advantages applicable to other glass melting systems.
