Abstract: The invention relates to a method for operating a combined cycle power plant, which includes a steam turbine powertrain with a high-pressure steam turbine, an intermediate pressure steam turbine and a low-pressure steam turbine, whereby intermediate pressure steam flowing from the exit of the high-pressure steam turbine to the inlet of the intermediate pressure steam turbine is reheated by means of the reheat device, and which is connected to a solar thermal plant, that generates additional solar steam for being used by said steam turbine powertrain. The output of the solar steam generator is used more effectively, and the overall plant performance, flexibility and operability are enhanced by at least part of the additional solar steam reaching the intermediate pressure steam turbine without being reheated in said reheat device.

Abstract: A turbine vane for a rotary turbomachine is described having a turbine blade which is delimited by a concave pressure-side wall and a convex suction-side wall which are connected in the region of a vane front edge which can be assigned to the turbine blade and enclose a cavity which extends in the longitudinal extent of the vane front edge and is delimited on the inner wall by the pressure-side wall and the suction-side wall in the region of the vane front edge and by an intermediate wall which extends in the longitudinal direction to the vane front edge and connects the suction-side wall and the pressure-side wall on the inner wall. The disclosed vane is distinguished by the fact that the intermediate wall has a perforation at least in sections in the connecting region to the suction-side wall and/or pressure-side wall, in order to increase the elasticity of the intermediate wall.
