The chamber has a base (14) connecting an annular outer wall (12) and an annular inner wall (13), where the walls and the base are welded together by butt welding. The base has windows (18) distributed circumferentially and closed by removable walls (20), where each removable wall constitutes a support for a set of injector systems (22). The removable walls are welded to the base so that the windows are completely closed. |
