A heat-resistant body has a cavity for exhaust gas, which is open at opposite ends. The body has first wall portions, each of which delimits a first portion of the cavity. Each first wall portion has an outer region and an inner region which has planar protrusions which each extend from the outside region inward into the associated first cavity portion, the planar protrusions tapering along the longitudinal extent in their width directed perpendicularly to the longitudinal extent and being mutually laterally spaced. Each planar protrusion of a first wall portion is rotated or shifted relative to a planar protrusion of an adjacent first wall portion. The body has second wall portions, each of which delimits a second portion of the cavity and is disposed between two adjacent first wall portions. The cross-sectional area of each second cavity portion is larger than the cross-sectional area of each first cavity portion.
An exhaust gas treatment device for treating an exhaust gas from a combustion process, comprising a heat-resistant body delimiting a cavity which is open at opposite ends and intended for the exhaust gas to flow therethrough, the body having a plurality of first wall portions, all of which delimit a respective first portion of the cavity, each first wall portion having an outer region and an inner region, which has a plurality of planar protrusions, all of which extend from the outer region inward into the respective first cavity portion, the planar protrusions tapering along the longitudinal extension in their width directed transversely to the longitudinal extension and being mutually laterally spaced, each planar protrusion of a first wall portion being rotated or shifted relative to a planar protrusion of an adjacent first wall portion,
A small combustion installation comprising an exhaust gas treatment device for treating an exhaust gas from a combustion process, comprising a heat-resistant body delimiting a cavity which is open at opposite ends and intended for the exhaust gas to flow therethrough, the body having a plurality of first wall portions, all of which delimit a respective first portion of the cavity, each first wall portion having an outer region and an inner region, which has a plurality of planar protrusions, all of which extend from the outer region inward into the respective first cavity portion, the planar protrusions tapering along the longitudinal extension in their width directed transversely to the longitudinal extension and being mutually laterally spaced, each planar protrusion of a first wall portion being rotated or shifted relative to a planar protrusion of an adjacent first wall portion,
