SGT-800 gas turbine highlights

Whatever the application, the SGT-800 meets your requirements for efficiency, reliability and environmental compatibility. As a result, you can expect lowest lifecycle cost of operation and the best possible return on investment.

The combustor and burner designs offer world-class emission performance over a wide load range and are capable of single-digit NOₓ and CO emission levels. 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.

Reliability has been a top priority from day one of the development of the SGT-800. Thanks to simple and robust technical solutions the reported average fleet reliability of the core engine and auxiliary systems over the last five years lies at a world-class 99.5%.

The SGT-800 offers broad flexibility in fuels, operating conditions, maintenance concepts, package solutions and ratings. These flexible solutions have been developed in order to satisfy your individual market-specific requirements.

Flexible service concept for on-site maintenance – hot section "strip", modules or gas turbine replacement

With its high electrical efficiency the SGT-800 is the core of your power plant installation – from simple cycle to combined cycle operation, with single or multiple units.

A hot climate option is available to further increase performance at high ambient temperatures.

Its excellent steam generation capability also makes the SGT-800 an ideal choice in combined heat and power (CHP) installations.

Ingenious design to the core

The SGT-800 industrial gas turbine combines a simple robust design for high reliability and easy maintenance with high efficiency and low emissions. The successive evolution of the SGT-800, based on experience of the installed fleet and on proven design solutions, ensures that you will get the the optimal performance and lifetime out of your gas turbine.

Standard options for hot and cold climates are available for operation at extreme ambient temperatures. The hot climate option offers 26% more power and a 5.8% reduction in heat rate at 50 °C.

 

 

Classic or single-lift?

Two different package solutions are available for increased flexibility in order to meet your individual requirements. Both are available for 50 Hz and 60 Hz markets.

 

 

The SGT-800 fires up

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 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 up to 60,000 equivalent operating hours (EOHs) between major overhauls the SGT-800 provides high operational availability.
Whether time-based or cycle-based, we offer flexible standardized maintenance concepts. On-site maintenance or modular overhaul, without the need for special workshop maintenance, is available for both package solutions. For the single-lift package, off-site maintenance with 48-hour core engine exchange is optionally available.

 

With its compact and modular setup, the SGT-800 gas turbine is designed for easy maintenance. The vertically split compressor casing enables easy access – a single-blade or a single-vane segment can be exchanged on site. For quick and easy inspections, the burners can be removed without cover lift.

 

 

Fuel flexibility matters

Whatever you need: The SGT-800 offers gas only or dual fuel (gas/diesel No.2) with on-load fuel-changeover capability. The excellent fuel flexibility allows for high content of inert gases, hydrogen and heavy hydrocarbons without any maintenance impact.

 

The low gas supply pressure requirement (27–30 bar[a] / 390–435 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 Emissions (DLE) combustion system to minimize NOₓ and CO emissions. With this gas turbine, capable of single-digit NOₓ and CO emission levels and world-class emission performance over a wide load range, you will comply with both global and regional regulations.
