For the new Al Dhafra power plant commissioned by TAQA
Geothermal - Energy from the heat of the earth
Ansaldo Energia’s first turbine-generator units driven by geothermal steam went in operation in Larderello (Italy) in 1911, powering what is considered the first geothermal power plant in the world – a milestone in the history of renewables.
Current Ansaldo Energia portfolio is based on impulse technology, and includes machines from one cylinder in single-flow configuration to two cylinders in double-flow configuration, with different exhaust solutions to suit plant layout requirements.
Top, lateral, axial discharge to the condenser are available in addition to the conventional vertical downward setup.
A broad selection of last-stage blades is available, ranging from 20 to 31 inches in diameter, for the best possible match with the specific geothermal field.
Thanks to Ansaldo Energia’s century-long experience and specific geothermal know-how, GT steam turbines guarantee high reliability and durability despite the harsh environment in which they operate – characterized by high levels of moisture, dissolved salts and acids. Special materials are used for rotor and blades to minimize the impact of corrosive chemicals.
