Abstract
An arrangement for filtering dust from hot gas, in which a housing is provided with a dirty-gas zone and a clean-gas zone, as well as porous-walled hollow structures that are continuous with the exception of an outlet opening into the clean-gas zone. A filtering tube surrounds the outlet and has an area with spherically convex base that rests against a support fixed in the clean-gas zone. Between the base of the tube and the support, there is an annular adapter which has a coefficient of linear heat expansion that is approximately at least that of the tube. The annular adapter rests against the convex base of the tube, and has a flat surface that rests against a matching flat surface on the support, so that the adapter can slide horizontally over the support that is fixedly connected to the clean-gas zone. The sliding of the adapter relative to the support occurs over oppositely-lying flat parallel surfaces, one of which is on the support and the other is on the adapter. The support and the adapter are free to expand in all directions due to the sliding action that is made possible.
