Definitions

  • This invention relates to means for preventing the formation of rust on the inner members of the turbine by the air or gas within the turbine being heated or kept at such a temperature that it becomes relatively dry.
  • the invention consists in that a heating element is placed inside the turbine or its outlet, the element, upon each stand-still of" the turbine, heating the air or gas circulating around the inner members of the same.
  • a heating element consists of a steam spiral tube connected with a boiler,
  • l ieferring to Fig. 1, 1 designates the turbine disk provided with the moving blades 2.
  • the steam flowing from the steam inlet 3 through the nozzle 4 actuates the turbine OF RUST IN TURBINES BEING AT REST.
  • the heating element may be placed at any point within the turbine or its' steam conduits.
  • the element is preferably mounted in the steam conduit betweenthe turbine and the condenser or altogether or in part in the condenser.
  • the steam may flow through the element either continually or only when the turbine is at rest.
  • heating element being placed within said conduit and arranged to heat the gaseous medium, so as to prevent the formation of rust.
  • a heating element being placed within saidoutlet conduit and arranged to heat the gaseous medium, so as to prevent the formation of rust.
  • a heating element being placed Wi thin said outlet, and a steam supply to said heating element and to the turbine and arranged to supply steam to either, so as to heat, when applied to the heating element, the gaseous medium in the turbine, whereby the formation of rust is prevented.
