A process for reducing the nitrogen oxides level in an effluent from the combustion of a carbonaceous fuel, which comprises preparing a water and hydrocarbon emulsion comprising a nitrogen oxides reducing treatment agent, wherein the reducing agent is an aqueous solution comprising a component selected from the group consisting of ammonia, urea, urea precursors, one or more of the hydrolysis products of urea, ammonium salts, urea complexes, amines, guanidine, guanidine carbonate, biguanidine, guanylurea sulfate, dicyanimide, calcium cyanimide, biuret, 1,1′-azobisformamide, methylol urea, a methylol urea-urea condensation product, dimethyl urea, and mixtures thereof; and a hydrocarbon having a boiling point which is lower than that of said nitrogen oxides reducing treatment agent, wherein the hydrocarbon comprises a component selected from the group consisting of a light crude naphtha fuel oil, hexane, ethyl ether, and mixtures thereof; and introducing said emulsion into the effluent from the combustion of a carbonaceous fuel under conditions effective to reduce the nitrogen oxides level therein.
