| | | Guide vanes and guide vane carriers Guide vane carriers are suspended ther-moelastically in the turbine casing and are split horizontally. Furthermore, the guide vane carriers are located axially by a shoulder in the turbine casing. In the horizontal plane, they are supported at the casing split joint by alignable spigot bolts and adjusted vertically by eccentric bolts. These fixing elements permit free expansion of the vane carrier in the radial direction and enable a centring fit under all operating conditions. The symmetrical design ensures dimensional stability even in the event of rapid temperature changes to maintain constant radial clearances. The guide vanes are fitted into the guide vane carrier by means of a hook root and are provided with a riveted shroud. Grooves in the low-pressure guide vane carrier remove free water via holes to the exhaust casing and so, directly on to the condenser manufacturer. This feature substantially reduces the free-water in the wet section of our condensing industrial turbines and reduces exhaust stage erosion to a minimum. | | |
