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 up to 60%
  • Nitrogen 40%
  • H₂S ≤ 3.5%

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

  • NOₓ emissions level < 9 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), we offer 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.

Excellent CC and CHP efficiency

Good combined cycle performance: In a 2x1 combined cycle configuration, the power output is 73.3 MW(e) at a net plant efficiency of 50.9%.

Comprehensive services to support you

Our comprehensive portfolio of services provides low life cycle cost and optimum performance throughout the turbine’s life cycle: Long Term Programs (LTP), overhaul service, field service, spare parts, service exchange, remote diagnostic service, and modernization and upgrades.

With only 17 scheduled maintenance days over a 17-year service cycle, the SGT-600 provides highest operational availability.  

Whether scheduled service or short-term support, our specialists are there for you, on-site or off-site all over the world. Our 24-hour global help desk ensures you peace of mind.

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 up to 60%
  • 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 ≤ 9 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: ≤ 9 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.)
