Abstract
A device and method for catalytic reduction of NOx in gaseous products of a combustion process before entry into the atmosphere. The gaseous and particulate products of a combustion process flow radially through a radial flow particulate filter element () that is effective to trap particulate matter, and are then directed axially through a collector (). An injector () introduces a reductant into an axial end of the collector for entrainment with axial flow through the collector in a direction away from the injector. Flow leaving the collector is directed through an SCR catalyst () where catalytic reduction of NOx occurs.
