Abstract
Vapour turbine operating with geothermal vapours containing corrosive agents such as chlorides and/or sulfides in particular. 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.
Claims8
A vapour turbine operating with geothermal vapours containing corrosive agents such as chlorides and/or sulfides in particular, characterized in that it 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 said geothermal vapours, maintaining a high useful life of said series of rotor blades and of said vapour turbine .
Use of a series of rotor blades made of a nickel-chromium-molybdenum-niobium alloy for a vapour turbine operating with geothermal vapours containing corrosive agents, such as chlorides and/or sulfides in particular, to avoid the washing of said geothermal vapours, maintaining a high useful life of said series of rotor blades.
