摘要
Has outer walls of the annular for guiding (30) the diffuser flow (28), exhaust gas diffuser for a gas turbine 1 A (20), exhaust gas diffuser invention, in (20) are arranged to influence the flow diffuser (30), exhaust gas diffuser guiding annular element which is arranged concentrically with respect to the outer wall (28) (32) is about (20). In order to improve the aerodynamic effect exhaust gas diffuser (20), and, in order to optimally adjust simultaneously the aerodynamic effect (20) exhaust gas diffuser of the operating state of the plurality of the gas turbine, the guide elements (32), A surface which has a boundary surface formed on the convex longitudinal section so as to form the moving element has a (34) surface facing radially inward, the guide elements In the first position, so as to allow the flow between the guide elements (32) outer wall and (28), and the guide element (32), at the second position (32), guide elements so as to prevent the majority of the distribution (32) of the outer wall (28), guide element (32) is movable in the axial direction between the two positions. Further, the present invention, there is provided a method of operating a (1) a gas turbine, in order to increase the pressure recovery with reducing aerodynamic losses, if the mass flow is increased, (32) second guide elements Move to the second position them or moving towards the position of, and / or, if the mass flow is reduced, the first guide element (32), or moving toward the first position moves to the position relates to a method.
