Definitions

  • a turbomachine such as an axial flow compressor comprising an outer casing, a rotor within said casing having rows of vanes, a guide vane carrier surrounding said rotor, said guide vane carrier supporting rows of adjustable guide vanes between which run the rows of vanes on said rotor, a shift member located in a chamber established between the outer casing and said guide vane carrier, mechanical connections between said shift member and said guide vanes for adjusting the angle of the latter as said shift member is actuated, means for introducing a dust-blocking water vapor containing gas into said chamber, and means for heating the wall parts defining said chamber to prevent cool-off to such temperature as would otherwise result in condensation of the water vapor on said Wall parts.
