Abstract
A method of reducing the nitrogen oxide level in flue gases from a fossil-fuel power plant in which NH.sub.3 is admixed with the flue gas as a reducing agent and the nitrogen oxides are largely converted to molecular nitrogen by reducing them with the ammonia in a reactor. Residual ammonia forms NH.sub.3 and NH.sub.4 substances which deposit and from time to time are taken up in a wash water which is disposed of by introducing it in the boiler.
