Jet for injecting and metering a treatment medium into the exhaust gas flow in combustion processes

摘要

The nozzle has an outer casing element (2) and an inner displacement body (1) to form a nozzle gap (14). The displacement body borders a mixing chamber (18) inside the casing element, and has a tapered area (3) in a transitional area between the mixing chamber and the nozzle gap. The mixing chamber communicates with a pressure chamber (6.1) for carrier medium. The feed element (5) supplies treatment medium (9) that enters into the mixing chamber. An independent claim is also included for a method for operating a nozzle.
