Abstract
A method for injecting an aqueous ammonia into a flue gas for reducing NO.sub.x in the flue gas comprises providing at least one tube pass in a path of the flue gas. As the vaporized aqueous ammonia and air mixture passes through the tube, it is injected into the flue gas. The flue gas raises the temperature of the remaining vaporized aqueous ammonia mixture for later use in vaporization of the aqueous ammonia.
