The addition of ammonia to the exhaust stream of stationary combustors is a promising approach toward reducing NO/sub x/ emissions. The use of high sulfur-content fuels will produce moderate quantIties of SO/sub 2/ aNd other sulfur-bearing compounds which may affect the effectiveness of this thermal deNO/sub x/ process. Modeling efforts''iNdicate that the presence of SO/sub 2/ is slightly beneficial in removing NO above 1250K. Experiments show that the ammonia-like species (NH/sub i/, i=1,2,3) have no appreciable reaction rate with SO/sub 2/. However, the reactions of SO/sub 2/ with OH and SO/sub 3/ with H have a small effect on the chemistry. A chemical model which fully describes the deNO/sub x/ process and the effects of SO/sub 2/ is presented.
