Abstract

Un dispositivo y método para la reduccion catalítica de NOx en productos gaseosos de un proceso de combustion antes de la entrada en la atmosfera. Los productos gaseosos y particulados de un proceso de combustion fluyen en forma radial a través de un elemento de filtro particulado de flujo radial (24) que es eficaz para retener las partículas, y a continuacion son dirigidas en forma axial a través de un colector (26). Un inyector (30) introduce un redactor en un extremo axial del colector para el arrastre del flujo axial a través del colector en una direccion fuera del inyector. El flujo que sale del colector se dirige a través de un catalizador SCR (40) donde se produce la reduccion catalítica de NOx.
