Definitions

the invention relates to an arrangement for vane carrier drainage in the case of a turbine in which guide vane rings are used for fastening guide vanes are provided in the guide vane carrier.
the invention can preferably Steam turbines are used.
the invention has for its object an arrangement for guide vane drainage in the case of a turbine of the type mentioned at the beginning, the one hand is inexpensive to implement and, on the other hand, technically very efficient.
At least one drainage collecting channel in the guide vane carrier is introduced, which is from a roof of a directly adjacent Guide vane ring is covered such that a gap for the entry of the condensate is formed between the roof and the vane carrier, at least a drainage hole in the at least one drainage gutter is introduced.
Drainage collecting channels 16 and 17 introduced into the guide vane carrier 2.
These drainage gutters 16 and 17 are partially covered 18 and 19 of the vane rings 10 and 11 covered. Since these canopies 18 or 19, however, narrower than the drainage collecting channels 16 or 17 gaps 20 and 21 remain for the entry of the condensate from the wall of the guide vane carrier 2 with the guide vane rings to the drainage collecting channels 16, 17.
These columns 20, 21 are preferably for the entry of the Condensate opposite the end tips of the blades 8, 9.
the drainage of the condensate from the drainage collecting channels 16 and 17 of the guide vane carrier takes place via drainage holes 22 and 23, respectively Guide the ends into the exhaust steam behind the guide vane carrier 2.
