ABSTRACT:
Disclosed is a process for non-catalytically removing NO from combustion effluent streams at temperatures from about 1300.degree. K. to 1600.degree. K. by injecting ammonia into a combustion effluent stream at a point where the stream is cooling at a rate of at least about 250.degree. K./sec, wherein the amount of ammonia injected and its point of injection are determined by the solution of a set of simultaneous equations derived from the kinetic model of Table I hereof.
