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.A device and method for catalytic reduction of NOx in gaseous products of a combustion process before entering the atmosphere. The gaseous and particulate products of a combustion process flow radially through a particulate filter element of radial flow (24) that is effective in retaining the particles, and then are directed axially through a manifold (26 ). An injector (30) introduces an editor at an axial end of the collector for the drag of the axial flow through the collector in a direction outside the injector. The flow leaving the collector is directed through an SCR catalyst (40) where the catalytic reduction of NOx occurs.
