Process for combustion flue gas conditioning, by injecting ammonia, in a very simple and viable way, in a stream of said combustion flue gas stream, characterized in that dissolved urea is hydrolyzed by heating under pressure to yield ammonia and carbon dioxide the hydrolysis product are stripped from the hydrolized solution by means of hot steam and injected into the flue gas stream while water coming out of the hydrolysed solution is reused to dissolve fresh urea to be fed to the plant.
