A method for decreasing radiation of NOx is provided to reduce emission of NOx by contacting nitryl compound to waste steam, auxiliary fuel stream and air at optimal temperature within a combustion area. Emission of NOx among exhaust gas in a stationary combustion system is decreased by contacting a kind of nitryl compound or more to absorber off-gas stream, auxiliary fuel stream and air at proper temperature for decreasing radiation of NOx within a combustion area of the combustion system. Nitryl is selected among nitryl compound displayed with a chemical formula of R-CN, and R is selected among hydrogen, aliphatic hydrocarbon radical, alicyclic hydrocarbon radical or aromatic hydrocarbon radical. Nitryl is added to the stationary combustion system by additional liquid supply stream, and the stationary combustion system is formed of a furnace.
