Southern California Gas Company (SoCalGas), the Institute of Gas Technology (IGT), and their industrial partners -- Combustion Tec, Inc. (CTI) and Air Products and Chemicals Company, Inc. (APCI) -- have initiated a program to develop a retrofit second-generation NO[sub x] control technology for natural gas-fired regenerative glass melters. The technology would also be applicable to many other types of high-temperature furnaces as well as to other advanced high-performance burners. This second-generation technology combines two NO[sub x] reduction techniques, both using oxygen enrichment: (1) a unique method of air staging to reduce the oxygen availability and somewhat increase the luminosity in the flame's high-temperature zone while improving flame temperature uniformity and (2) natural gas cracking in a separate oxygen/natural gas cracker to substantially increase the flame luminosity. Versions of these techniques were tested on IGT's pilot-scale glass tank simulator during earlier efforts and showed excellent potential for NO[sub x] reduction. Furthermore, the concept of oxygen/natural gas cracking has already been demonstrated on a pilot-scale cracker. This paper reviews the results from the earlier development work by IGT, CTI, and others; describes the proof-of-concept testing of the pilot-scale oxygen/natural gas cracker; and discusses the status of the current program as well as other potential combustion modifications for NO[sub x] reduction.
