Description

GE’s STF-G220 (GST) geothermal steam turbines offer simple and robust technology for geothermal projects and industrial low-pressure expander applications. Their flexible impulse steam path offers a low heat rate to help reduce corrosion stress cracking and scaling buildup. Durability and flexibility for your plant Created with integration in mind The STF-G220 features a horizontal steam inlet, a hot end drive and axial exhaust, to facilitate a floor level installation. Its lightweight transport frame simplifies transport and installation, while the panting plate support eliminates the need for a spring foundation Configuration flexibility The STF-G220 steam path can be fitted with up to 7 stages to accommodate a wide range of geothermal steam conditions. It can also be re-staged without rotor machining in order to adapt to deteriorating resource quality. Durable and robust Critical areas are protected by surface hardening, stellite plating, and surface coating to mitigate stress corrosion risks and ensure long parts life even under harshest conditions. Key features • Reliable even under harsh conditions thanks to use of erosion and corrosion resistant materials specifically selected for wet steam and aggressive media • Highly efficient steam path with modern 3D impulse blading and advanced rear stage profiles • Robust governor valves with self-cleaning non-contact seats made from stellite reliably prevent scaling buildup and minimize wear • Compact transport module with light but stable base frame simplifies alignment and installation.
