Abstract
A denitrification system comprises an electrostatic precipitator (3) in the foremost stage of the system inlet, an ozone supply nozzle (4) for an ozonizer (5) for generating ozone required for oxidizing the NO into NO.sub.2, followed by a fan or an agitator (6), and an NO.sub.2 absorbent filter (7) in the final stage arranged in that order. Further, this system may comprise the control of feeding back the residual O.sub.3 concentration after oxidation, to achieve the higher denitrification rate.
