Zusammenfassung:The gas channel (17) has concentric inner housing (19) that is surrounded by outer housing (18), through which exhaust gases from gas turbine are discharged outside. The inner housing and outer casing are interconnected by several radial supports (20). The supports, outer housing and inner housing are equipped with refractory linings (19a,20a) for protection against hot exhaust gases. The linings are releasably fastened to support structure, such that stress-free thermal expansion of linings is ensured in all operating conditions.
