Compressor
The SGT-600 core engine features a 10-stage flow transonic compressor with variable guide vanes for robust operability and optimizied performance over a wide range of operating conditions.
Free power turbine
The 2-stage uncooled free power turbine offers you a nominal shaft speed of up to 7,700 rpm.
For mechanical drive, it may operate at 50 to 105% of the nominal speed.
The blades use interlocking shrouds for extra robustness.
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).
Power generation package
The SGT-600's ability to handle sudden load changes and its high exhaust temperature make it ideal for simple cycle, combined cycle, cogeneration, and other heating applications.
- Small footprint for easy fitting
- Modular and flexible package design
- Single-lift capability
Mechanical drive package
The SGT-600 mechanical drive packages offer long lifecycles and can withstand extreme climates ranging from desert heat to arctic cold, oil platforms, and harsh industrial environments.
-Variable power turbine speed: 50 to 105%
-High load on low-power turbine speed
-Maintains efficiency at part load
-Low emissions at part load
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.
Easy on-/off-site maintenance
The SGT-600 is designed for maximized serviceability.
Both on-site maintenance and a gas generator removal for off-site maintenance are possible.
Gas generator swap is performed within 24 hours.
Remote diagnostic service
Our remote diagnostic service helps you to detect faults at an early stage and prevents outages.
The service includes online monitoring, expert performance data analysis, and fleet data comparisons.
Designed for easy serviceability
Burners are accessible from the outside for easy replacement.
Compressor casing is horizontally split, and the turbine casing is vertically split between gas generator and power turbine.
Multipe boroscope holes allow for internal visual inspection of the compressor.
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%
