Abstract
The nozzle for introducing and for metered addition of a treatment medium into the exhaust gas stream in combustion processes comprises a nozzle tube (2) and an inner displacement body (1) having a round cross section to form a nozzle ring gap (14). The displacement body (1) borders a mixing chamber (18) inside the nozzle tube (2) and on this end has a tapered area (3) with which it is held exclusively on a feed tube (5) for the treatment medium. The feed tube (5) crosses through a pressure chamber (6.1), which has two axial bordering walls (4, 7). The feed tube is held in these bordering walls, with a holder (12) being provided in the bordering wall (4), allowing the carrier medium from the pressure chamber (6.1) to flow through to the nozzle gap (14).
