11-025	Renato Pereira da Silva Junior	Silva Junior, R.P.(Air Products); D'Agostini, M.D.(Air Products); Basilio, E.E.(Air Products);	As oxy-fuel glass melting has steadily grown in industry acceptance since its introduction roughly three decades ago, so has the sophistication of oxy-fuel burners, which have evolved from simple pipe-in-pipe designs to the current state-of-the-art, which is flat (wide) flames with on-board burner sensors and oxygen staging controls that enable precise adjustment of flame properties for high efficiency, high quality melting with ultra-low NOx emissions. This paper presents a chronological perspective of Air Products’ oxy-fuel burner technology development, with emphasis on how, through customer engagement and innovation, each successive generation of burner technology has provided added commercial value. Development has culminated with our latest offering, the Cleanfire® HRx burner, that has already proven its ability to achieve, among other things, ultra-low NOx emissions and reduction of surface foam in several industrial glass melting furnaces.
