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 immediately before or directly into a zone where the combustion effluent is cooling at a rate of at least about 250.degree. K.
