Waste gas purification assembly and method for transporting a reaction agent into the waste gas flow of same

摘要

The system (1) has input-sided and output-sided open reaction pipes aligned in a flow direction of exhaust gas and spaced from an inner wall (13) of an exhaust section (2) with an outer mantle surface and built in the exhaust section. An input opening (14) of an reaction pipe (11) is formed in a section of the exhaust section, and arranged as a high static pressure section against a section in which an output opening (15) is formed during operation of the system. A dosing nozzle (16) is arranged in the reaction pipe for outputting reactant.
