PROCEDE DE MONTAGE D'UNE BUSE D'INJECTION DE GAZ EN TRAVERSEE D'UNE PAROI ET MOYENS POUR LA MISE EN OEUVRE DE CE PROCEDE

摘要

The invention concerns a process for fitting a gas-injecting nozzle in the wall of an installation. The process is characterized in that: an external supporting surface (11) whose shape matches the so-called internal supporting surface (12) of the passage (6) provided in the bedding brick is associated with the nozzle (2); the nozzle is placed opposite the passage (6) in the bedding brick; the nozzle (2) is moved in axial translation so as to adjust the position thereof along the longitudinal axis of the passage and move the front face of the nozzle into a desired initial position; the nozzle is locked in this desired initial position; and, at least periodically, the nozzle is inserted further forwards into the passage in the bedding brick in order to compensate the wear in the front face of the nozzle. The invention can be used to prevent clogging, such as in a cement-producing plant.
