NOx Removing System Using Urea as Reduction Catalyst

摘要

The present invention relates to a urea tank for storing urea; A urea supply pump for supplying urea from the urea tank to high-frequency induction heating; High frequency induction heating for rapidly heating the urea supplied from the urea supply pump; A spray nozzle for spraying the product pyrolyzed by the high frequency induction heating in a reaction space; A compressed air supply for supplying compressed air to the reaction space; A blocking damper for blocking supply of the combustion gas; And a reaction space in which a combustion gas and a pyrolyzed product of urea react with each other to reduce nitrogen oxides, and a method for removing nitrogen oxides using the same.
