WET SCRUBBING APPARATUS AND METHOD FOR CONTROLLING NOx EMISSIONS

摘要

An apparatus (1) for controlling NOx emissions which includes a chamber having a wall surface (114) and an interior (110), a flue gas entrance (100) and a flue gas exit (108) for a flue gas to enter and exit the interior of the chamber, a gas quenching zone (102) in which the temperature of the gas can be lowered, an ozone injection and retention zone (104) in the chamber, and a liquid spray zone (106) including at least one spray nozzle (200) for spraying a liquid towards the wall surface.
