A rotating blade for a steam turbine includes a root section and an airfoil section contiguous with the root section. The airfoil section is shaped to optimize aerodynamic performance while providing optimized flow distribution and minimal centrifugal and bending stresses. The blade also includes a tip section continuous with the airfoil section, and a cover formed as part of the tip section. The cover defines a radial seal that serves to minimize tip losses. The rotating blade is capable of running at operating speeds between 5626 and 11250 rotations per minute.

Steam turbine rotating blade

Vapor turbine operating with geothermal vapors containing corrosive agents such as chlorides and/or sulfides in particular. The turbine comprises a series of sealing laminas made of a nickel alloy containing a quantity of nickel ranging from 54% to 58% by weight to avoid the washing of the geothermal vapors, maintaining a high useful life of the series of sealing laminas and vapor turbine.

Vapour turbine

Vapor turbine operating with geothermal vapors containing corrosive agents such as chlorides and/or sulfides in particular. The turbine comprises a series of stator blades made of a nickel alloy containing a quantity of nickel ranging from 54% to 58% by weight to avoid the washing of the geothermal vapors, maintaining a high useful life of the series of stator blades and vapor turbine.
