Device for treating waste gases resulting from technical combustion processes

A device for treating exhaust gases (1) which is arranged in the exhaust-gas stream from an internal combustion engine or in the exhaust-gas line from stationary combustion installations and which has a feed-line connection stub (3) and a discharge-line connection stub (4), which are held on a housing (6) which contains a filter material (19) which has at least one fabric layer made from metal wires or metal fibers, characterized in that for diversion, particulate retention and muffling purposes there are shaped bodies (8) in the housing (6), which consist of metallic fiber composite (19.1, 19.2) as composite material, the empty spaces (11, 16, 17) in the housing (6) being filled with metallic fiber material,

• wherein in a region of an inlet end face (7) of the housing (6) the proportion of stainless steel material (19.2) in the composite material (19) is higher than at the outlet-side boundary (14) of the housing (6), in order to conduct heat out of the incoming exhaust-gas stream (1).
