Abstract

Procedimiento de depuración de humos de combustión que contienen unos óxidos de nitrógeno y unos contaminantes ácidos, en el cual: - en una zona en la que los humos que se van a tratar presentan una temperatura comprendida entre 750 ºC y 1.150 ºC, preferentemente entre 850 ºC y 1.100 ºC, se inyecta un agente reactivo (10) de desnitrificación y se ajusta el flujo de inyección de este agente reactivo (10) de forma que se realice una desnitrificación no catalítica y selectiva, que tiene un rendimiento comprendido entre el 40% y el 80%, - en los humos (1) que resultan de la desnitrificación no catalítica y selectiva, se introduce una mezcla reactiva (9; 9'), que contiene un catalizador de desnitrificación, en forma dividida y un reactivo básico de captación de los contaminantes ácidos, en una proporción tal que el catalizador constituye entre el 5 y el 30% en peso de la mezcla reactiva, - a continuación, se hacen circular los humos (2) que contienen la mezcla reactiva (9; 9') en un separador gas15 sólidos (103), - antes de reintroducir antes del separador gas-sólidos una fracción mayoritaria (6) de los residuos sólidos (4) extraídos del separador gas-sólidos (103), se admite esta fracción mayoritaria (6) en un reactor de activación (201) en el cual se admite igualmente vapor de agua (10) como fluido de regeneración del catalizador, y - se evacua la fracción minoritaria restante (5) de los residuos sólidos (4) extraídos del separador gas-sólidos (103).
