Abstract

An apparatus for controlling the emissions of nitrogen oxides from a combustion system includes at least one nozzle assembly having an array of openings for delivering droplets of a fluid chemical agent to a flue gas within the combustion system; a controller operatively coupled to the at least one nozzle assembly for controlling the size and distribution of each droplet; an excitation mechanism operatively coupled to the at least nozzle assembly for providing additional control over the size and distribution of each droplet; and the array of openings arranged for deflecting the droplets to prevent droplet collisions.
