This paper presents an overview of NO, emission control options for the glass industry. In general, control options can be classified as process modifications, combustion modifications, and postcombustion (or add-on) equipment. Potential NO,-reducing techniques in the process modification category are generally put in effect or in place for reasons other than NO, control, the NO, control being a “side effect.” In the other two categories are a wide range of potential or candidate options; however, only a limited number have been reduced to proven practice. The vast majority of NOx control options are still in the developmental or early commercialization stage. On a practical level, only modest NO, reductions from combustion modifications of the burner/port arrangement and moderate NO, reductions due to application of noncatalytic ammonia injection have demonstrated the consistent ability to reduce NOx from glass furnaces. After providing a generalized categorization and overview of the range of NOx control options, this paper will spend some lime focusing on the technique currently reduced to practice and the most predictable in its ability to achieve required NOx reduction, namely, noncatalytic ammonia injection. A more in-depth review of this technology and its practical application and limitations is presented. Finally, some useful insight and hardware description of a typical ammonia injection system is provided based on actual design and installation experience.
