ABSTRACT:
A transition element between components of a flue-gas duct of a gas turbine includes a first heat-insulation element for reducing material stresses between the components during operation of the gas turbine. The thickness of the heat-insulation element varies as a function of a spatial variable along the flue-gas duct, to set a prescribed temperature profile in a transition region. A second heat-insulation element is provided for permitting a transition from an internally insulated component to an externally insulated component. The thickness of the second heat-insulation element varies in the opposite direction to the thickness of the first heat-insulation element.
