A sealing arrangement for a duct, through a stationary housing, of a shaft which rotates about an axis is provided, wherein a sealing liquid is used for sealing instead of sealing steam. The sealing arrangement includes a seal, having a vapor steam extraction system, and a feed line, which is arranged between the inner space and the vapor steam extraction system and is designed for supplying a sealing liquid, wherein a labyrinth seal, a brush seal with metallic bristles, a brush seal with bristles made of natural fibers and/or a brush seal made of synthetic fibers is provided for sealing off with respect to the inner space and the vapor steam extraction system.

Sealing arrangement of a steam turbine in which a sealing liquid and a vapor steam extraction system are used

A safety device for a turbine blade is provided. The safety device includes a shear pin, a clamping piece and a securing element, wherein the shear pin is arranged in a corresponding bore in the turbine blade foot and the clamping piece is designed having an upper limb and a lower limb, wherein the clamping piece exerts a radial force on the turbine blade foot for radial safeguarding.

Blade fastening having safety device for turbine blades

A turbine-blade locking device having a wedge movable in an axial direction is disclosed. The wedge is movable in the axial direction by a tensioning device, as a result of which a force is produced in the axial direction. The force in the axial direction causes the turbine blade to be pressed against the blade holder.
