Twin-shaft engine for mechanical drive and power generation
Year 2018
Model SGT400 - 50 Hz
New surplus – never installed
Evolution in rotors, blades and combustion technology enhances efficiency, flexibility and availability
The SGT-400 is a simple, robust twin-shaft gas turbine, suitable for both power generation and mechanical drive applications
Services the 10 – 15 MW power band and can be used in all climates, onshore and offshore
A technological leap forward when it debuted 20 years ago, the SGT-400 continues to be a leader in operational and fuel flexibility, low emissions and overall efficiency
Enhancements to rotors and blades combined with local support and a 33% increase in the time between overhauls ensure high availability and low lifecycle costs
Recent advancements like the can-annular design with single-stage combustion mean the SGT-400 can burn a wide range of fuel compositions and run efficiently at all loads
Can meet stringent emissions standards while running loads as low as 30% and has seamless, true dual-fuel capability
Core Engine
Ingenious design to the core
The SGT-400’s twin-shaft design is simple yet robust
Features a two-bearing gas generator rotor with an 11-stage axial flow transonic compressor and a two-stage, overhung compressor turbine
The SGT-400 free power turbine also has a robust two-stage, overhung design
Enhancements to rotors and blades have extended the availability of the turbine, which permits output speeds up to 10,000 rpm (12,075 rpm for the 11 MW configuration)
The rotors are contained in heavy-duty casings that are horizontally and vertically split, so maintenance can be carried out on-site as needed
The compressor uses variable guide vanes for robust operability and optimized performance across a range of operating conditions
High-chrome blades for high-corrosive environments are also an option
The gas turbine is equipped with a DLE combustion system to achieve low NOx emissions with both gaseous and liquid fuels
The can-annular, single-stage combustor technology can burn a wide range of fuel types and quality – including liquid fuels or gas directly from wells
Advanced controls enable true dual-fuel capability, with seamless switching between fuel types without losing production
