The Siemens SGT-400 is a high-performance, robust twin-shaft gas turbine, suitable for both power generation and mechanical drive applications. These gas turbines are brand new, manufactured in 2022, and have never been used before. This turbine is known for its operational and fuel flexibility, low emissions, and overall efficiency. It can burn a wide range of fuel compositions and run efficiently at all loads, including loads as low as 30%. The SGT400 offers seamless, true dual-fuel capability.
Extended service intervals of 32,000 hours for the hot gas path, with 64,000 hours before the first major overhaul. This unit has zero hours.
Fuel flexibility allows the turbine to burn many fuel types and qualities, including liquid fuels and gases with high inerts. It can burn up to 10 vol% of hydrogen (H2) when equipped with DLE burners and up to 65 vol% of hydrogen (H2) when equipped with diffusion burners. 3. Twin-shaft design enables efficient operation across a broader range of power – from 10 to 15 MW.
The turbine has intelligent automatic adjustment of fuel split during starting and during operation to compensate for load, ambient, and fuel composition changes, thereby minimizing emissions.
Ideal for onshore or offshore oil and gas industry applications due to its compact dimensions, on-site or off-site maintainability, and high reliability. It can be used as a direct drive for compressors or pumps, or for power generation. Suitable for onshore use in oil fields or refinery applications and offshore on platforms and FPSO vessels.
It is also ideal for industrial power generation in simple cycle or combined cycle applications and combined heat and power (CHP) uses.
The SGT-400 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. 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.The gas turbine is equipped with a DLE combustion system to achieve low NOx emissions with both gaseous and liquid fuels.
