Abstract: The present invention relates to an apparatus and a method for the selective non-catalytic reduction (SNCR) of NOx in industrial cement production plants. In particular, the method according to the present invention provides for the atomization of an aqueous solution containing the reagent by introducing it into the gas to be treated that is at a high temperature, thus achieving the simultaneous and immediate evaporation of the water and gasification of the reagent. Thanks to this method, there is achieved improved performance of the non-catalytic reduction process of NOx while using the same reagent or, specularly, the same performance with a lesser amount of reagent being required, with consequent reduction of the costs.
