摘要： A vapour turbine operating with geothermal vapours containing corrosive agents such as chlorides and/or sulfides in particular is described. The turbine comprises a series of rotor blades made of a nickel alloy containing a quantity of nickel ranging from 55% to 59% by weight to avoid the washing of the geothermal vapours, maintaining a high useful life of the series of rotor blades and vapour turbine.
