    Technology

    Reliable, robust, and flexible power generation

    The SGT6-2000E gas turbine is a proven, robust engine for the 60 Hz market, used in simple cycle or combined cycle processes, with or without combined heat and power. It is suitable for all load ranges, including peak load, and offers outstanding fuel flexibility: You can use low-calorific gases or gases containing CO₂, H₂S and N₂ or crude oil and other liquid fuels with high viscosity. In addition, it provides low NOₓ emissions, even in the part load range.

    Highlights of the SGT6-2000E gas turbine

    The extensive fleet operating experience of the SGT6-2000E lets  you benefit from best-in-class fleet reliability of > 99%. Its robust turbine design is continuously enhanced by high-performance upgrades.

    Thanks to its fast start-up capability, you will achieve full load in only about 10 min. With its fast load change capability, in turn, you will meet the most stringent grid requirements for optimal frequency stabilization.

    The SGT6-2000E offers dual-fuel capability and excellent fuel flexibility: It can be fired with low calorific gases or gases containing CO₂, H₂S and N₂, as well as with crude oil and other liquid fuels with high viscosity.
    It provides reliable start-up and changeover between fuels. The automatic changeover from the primary to the secondary fuel can be carried out at reduced base load.

    This robust engine is suitable for a wide range of ambient conditions such as cold climates, hot and dry or dusty environments.

    For hot and dry conditions, we offer these options to increase your power output:

    • An evaporative cooler or an inlet air chiller with heat exchangers to avoid performance degradation
    • A Wet Compression (WetC) system to enhance turbine performance by reducing compressor inlet temperatures and increasing the mass flow throughout the turbine

    The SGT6-2000E is designed for easy maintenance to reduce outage times:

    • Rotor de-stacking/re-stacking on site
    • Blades can be individually replaced without rotor lifting
    • Vane carriers can be removed without rotor lifting
    • Minor inspections can be done through the spacious combustion chambers

     

     

    Ingenious design to the core

    The SGT6-2000E core engine has a horizontally split casing and two walk-in combustion chambers, equipped with individually replaceable ceramic tiles. This design allows a hot-gas-path inspection without cover lift. The 17-stage axial-flow compressor with variable-pitch inlet guide vanes enhances peak load operation and supports frequency stabilization.

    The robust 4-stage turbine incorporates the latest blade and vane design for stable, improved performance. The hybrid burners are able to operate in premix and diffusion mode with natural gas, fuel oil and special fuels such as heavy oil and refinery residues. The Low-NOₓ combustion system, single-digit NOₓ emissions can be achieved.
