Abstract (en)

[origin: EP0825393A2] The return flow connection (4) is mounted with a return flow distributor pipe (R) on the housing (1) off-centre in the upper area of the housing away from the centrally mounted header connection (3). In the area underneath the distributor pipe (R) are several stacked flow guide webs (8) set between the outer housing wall (1') and adjoining wall which is biased by the hot gases, The flow guide webs are associated with each other so that they form injectors (9) directed against the outside wall of the housing whereby the distributor openings (10) on the distributor pipe (R) are directed into the area between the flow guide webs and the housing wall. The bottom web can be slightly concave relative to the return flow direction and those above are slightly convex.
