Abstract: The origin, effects, and abatement procedures for oxides of nitrogen emissions from stationary sources are examined. In assessing the most promising short-range methods for abating NOx it is seen that gas recirculation and off-stoichiometric operating conditions offer the most promising abatement technologies. The difficulty with implementing the various abatement strategies is that one cannot, in general, predict prior to installation what degree of NOx reduction will be attained. The most recent findings suggest that many boiler manufacturers will guarantee 50% NOx reduction with oil or gas fired installation if gas recirculation methods are used. For all other methods the degree of control to be expected varies with the particular boiler under review. The prediction of expected efficiency remains the challenge of the future innovations in NOx emission control for stationary sources.
