    Highlights of the SGT-600 gas turbine

    The SGT-600 offers best-in-class fuel flexiblity that allows for high content of inert gases, hydrogen and heavy hydrocarbons:

    • Ethane 100%
    • Propane 100%
    • Butanes and heavy alkanes 15%
    • Hydrogen 65%
    • Nitrogen 40%
    • H₂S ≤ 3.5%

    The SGT-600 features a third-generation dual-fuel Dry Low Emissions (DLE) combustion system:

    • NOₓ emissions level < 15 vppm
    • CO emissions level  < 20 vppm
    • Turn down 50% load
    • Same DLE system for dual and liquid operation
    • NOₓ emissions on liquid fuels < 58 ppmvd
    • CO emissions on liquid fuels < 25 ppmvd
    • Turn down 50% on liquid fuels
    • Dual-fuel DLE capability with fuel changeover capability (gas to liquid fuel and liquid fuel to gas) on load

    The SGT-600 features a reliable, robust and easily maintainable design for maximized uptime.

    • Reliability > 99%
    • On-site or off-site maintenance
    • 24-hour swap capability
    • 17 maintenance days in 17 years
    • 34,000 equivalent operating hours (EOH) between hot section inspections
    • Part load operation increases the time between overhauls

    Thanks to a long lifetime with maximized uptime, low life cycle cost and easy servicability, the SGT-600 offers you a high lifetime profitability. The robust industrial design offers a low degradation over time.

    Ingenious design to the core

    The SGT-600 offers you best-in-class availability thanks to a robust and reliable design.

    The compact twin-shaft engine is easy to maintain and allows for flexible operation.


    Using the same design for power generation and mechanical drive increases the operational experience.

     

     

    SGT-600 power generation and mechanical drive packages

    Thanks to the compact architecture, the SGT-600 package offers you a small footprint. The package has a modular and flexible design and features single-lift capability.
    The driver for both power generation and mechanical drive package is the same.


    A gas turbine package includes:
    Gas turbine, enclosure, base frame, air intake, exhaust, lubricating systems, starter system, vibration monitoring system, firefighting system, package ventilation system, instrumentation, gas detection, fuel systems, gearbox (if needed).

     

     

    SGT-600-based power plants

    For combined cycle and cogeneration (combined heat and power – CHP), Siemens offers a broad range of power plant configurations and scopes based on the SGT-600 gas turbine. For combined cycle, 1x1 or 2x1 configurations are part of the standardized portfolio.

    High fuel flexibility

    The SGT-600 offers best-in-class fuel flexibility that allows for high content of inert gases, hydrogen and heavy hydrocarbons:

    • Ethane 100%
    • Propane 100%
    • Butanes and heavy alkanes 15%
    • Hydrogen 40%
    • Nitrogen 40%
    • H₂S 3.5%

     

    Features:

    • Available with both conventional and DLE combustion systems
    • Gaseous and liquid fuels on-load changeover
    • Third-generation DLE system
    • Best-in-class NOₓ emission levels

     

    The SGT-600 requires low gas supply pressure at site:
    24.5 bar(a) / 355.5 psi(a).

    Low emission capability

    The combustor and burner design give world-class emission performance over a wide load range and are capable of ≤ 15 ppmvd NOₓ emission levels.
    Low emission levels are also received on liquid fuel without need of water injection.

     

    Emissions for 100 – 50% load, NOₓ at 15% O₂:

    • Natural gas: ≤ 15 ppmv
    • Diesel No. 2: ≤ 42 – 58 ppmv

     

    Emissions for 100 – 50% load, CO at 15% O₂:

    • Natural gas: ≤ 10 – 80 ppmv
    • Diesel No. 2: ≤ 10 – 80 ppmv

     

    (Emissions depend upon site conditions, required load range and other project-specific data.)
