Abstract
Disclosed is a method for non-catalytically reducing the concentration of NO in combustion effluents by the injection of ammonia into an effluent stream where the stream is at a temperature from about 975.degree. K. to 1300.degree. K. More particularly, the amount of NH.sub.3 and its point of injection are determined by the solution of a set of simultaneous equations derived from the kinetic model disclosed herein. Particular benefits of the present invention occur when ammonia is injected into a cooling zone.
