  "textContent": "The invention refers to a gas duct (17) for a gas turbine, which gas duct (17) is formed by a concentric inner casing (19) and an outer casing (18) which concentrically encompasses the inner casing (19) at a distance, and through which the exhaust gases from the gas turbine discharge to the outside, wherein the inner casing (19) and the outer casing (18) are interconnected by means of a multiplicity of radial support struts (20), and wherein the support struts (20), the outer casing (18) and the inner casing (19) are equipped in each case with a heat-resistant lining (19a or 20a) for protection against the hot exhaust gases. Easy accessibility and an extensive reduction of thermal stresses is achieved by the linings of the support struts (20), of the outer casing (18) and of the inner casing (19) being divided in each case into a plurality of separate segments (19a, 20a) which are fastened on a support structure in such a way that an individual thermal expansion of the individual segments is possible.",
