Connecting element for conduit segments through which hot flue gas can flow

摘要

A conduit assembly, in particular for connecting a flue gas inlet of a gas turbine to a flue gas conduit discharging into a waste heat boiler, includes an outwardly insulated first conduit segment having a supporting inner casing, and an inwardly insulated second conduit segment having a supporting outer casing being radially outwardly offset from the supporting inner casing of the first conduit segment. The supporting casings each have a flange-like structure and are form-lockingly joined together in a connection region between the conduit segments. A connecting element for the conduit segments includes a shaped element surrounding the first conduit segment and being firmly joined to the supporting outer casing of the second conduit segment. The shaped element has a number of radially extending ribs with free ends being form-lockingly joined to the supporting inner casing of the first conduit segment.
