Method for feeding at least one reactant into an exhaust gas flow and device for treating the exhaust gas flow in a combustion engine

摘要

The method involves partial conversion and partial separation of a component of an exhaust gas stream (5). A reactant stream (10) is added to the exhaust gas stream such that a part of the reactant stream meets on the element (3). The reactant stream includes a drop of 30 micrometers in the diameter. A decomposition reaction of one component of the reactant stream takes place in the area in which the reactant stream meets the element. The reactant stream comprises a reducing agent and a reducing agent precursor. An independent claim is also included for a device for processing an exhaust gas stream of an internal combustion engine.
