SGT-800

With a proven, long-term track record of successful installations around the world, the SGT-800 gas turbine is an excellent choice for both industrial power generation and oil and gas applications.

It will meet your requirements for efficiency, reliability and environmental compatibility, offering low lifecycle costs and the best possible return on investment. The SGT-800 will support your combined cycle and cogeneration installations with its excellent efficiency and outstanding steam-raising capability. Designed for flexible operation, it is perfectly suited for base and intermediate load as well as grid support.

The combustor and burner designs offer world-class emission performance over a wide load range with single-digit CO emission levels and capable of down to 9 ppm NOx emissions. Low emissions are also achieved with liquid fuel without the need of water injection.
Designed to reduce environmental impact, the SGT-800 gas turbine will help you meet even the strictest emission regulations worldwide.

The SGT-800 features a compact, modular, maintenance-friendly design. This maintainability combined with the turbine’s robust single-shaft arrangement, long time between overhauls and long lifetime ensures its high operational availability.
Flexible service concepts for on-site or off-site maintenance with possibility for 48-hour core engine exchange will maximize the availability even further.

Green biofuels: A proven fuel for gas turbines

SGT-800 classic package

The classic package comprises preassembled modules with the gas turbine and gearbox on a single base frame.
Mechanical auxiliary systems are mounted on a separate skid within the enclosure.
A modular package allows for easy transportation and straightforward on-site installation.
On-site maintenance, inspections, and overhauls are conveniently performed within the enclosure, providing added ease and efficiency.

SGT-800 single-lift package

The single-lift package is a preassembled unit available in two configurations: as a single-lift driver unit(i.e. gas turbine, gearbox and mechanical auxiliary systems on a single base frame) with the generator on the foundation, or as a complete skid-mounted train for 3-point mount installations, e.g. for power barges (SGT-800 SeaFloat).
It offers a small footprint and the potential for a 48-hour core engine exchange.
The single-lift operation of the driver unit or complete train results in a short installation and commissioning time on site.
A special US-adapted option is available for specific requirements.

SGT-800-based power plants

Flexibility and efficiency are key for your power plant solutions. The excellent efficiency and steam-raising capability of the SGT-800 gas turbine make it outstanding in cogeneration – also called combined heat and power (CHP) – and combined cycle installations.

We offer you a broad range of power plant configurations based on one or multiple SGT-800 gas turbines. Within our standard plant configuration we can offer a high degree of scope flexibility. This enables plant optimization to suit your specific requirements, such as island-mode operation or multiple power blocks.

Flexible maintenance – high availability

Our comprehensive service portfolio ensures low life cycle costs and optimal performance throughout the turbine’s life cycle, including:

Long Term Programs (LTP)
Overhaul service
Field service
Spare parts
Service exchange
Remote diagnostic service
Modernization and upgrades

The SGT-800 offers high operational availability with up to 60,000 equivalent operating hours (EOHs) between major overhauls. We provide flexible standardized maintenance concepts, whether time-based or cycle-based. On-site maintenance or modular overhaul is available for package solutions, while the single-lift package offers off-site maintenance with 48-hour core engine exchange as an option.

Designed for easy maintenance, the SGT-800's compact and modular setup allows for convenient access. The vertically split compressor casing enables easy on-site component exchange, and the burners can be quickly removed for maintenance inspections.

Fuel flexibility matters

Whatever you need: The SGT-800 offers gas only, liquid only (Diesel No.2) or dual fuel (gas/liquid) with on-load fuel-changeover capability. The excellent fuel flexibility allows e.g. for high content of inert gases, hydrogen and heavy hydrocarbons in the gas fuel composition without any maintenance impact. The engine, equipped with DLE burners, is capable to burn up to 75 vol% of hydrogen (H₂).

The low gas supply pressure requirement (27–31 bar[a] / 390–450 psi[a]) reduces the need for a gas compressor on site.

Best-in-class NOₓ and CO emission levels

All SGT-800 units are equipped with a robust dual-fuel Dry Low Emission (DLE) combustion system to minimize NOₓ and CO emissions. The combustor and burner designs offer world-class emission performance over a wide load range with single-digit CO emission levels and capable of down to 9 ppm NO_x emissions. With this gas turbine you will comply with both global and regional regulations.

H2-Readiness - TÜV SÜD certificate

TÜV SÜD has developed a guideline for defining the “H2-Readiness” of power plants and is offering an independent certification to original equipment manufacturers and engineering, procurement, and construction (EPC) companies. The certification increases investment security for utilities. Siemens Energy is the first company worldwide to receive this certification for its “H2-Ready” power plant concept for the SGT-800. The guideline for obtaining certification was developed in collaboration with subject matter experts from Siemens Energy.
