High reliability, excellent fuel flexibility and third-generation DLE make the SGT-600 a perfect choice for applications like industrial power generation in combined heat and power (CHP), and combined circle power plants (CCPP), onshore oil and gas power generation, as well as mechanical drives.
Highlights of the SGT-600 gas turbine
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
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.
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%
- 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.)
