SGT-800 gas turbine

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.

Standard options for hot and cold climates are available for operation at extreme ambient temperatures.

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.

Excellent combined cycle and combined heat and power efficiency

One or multiple SGT-800 gas turbines provide the core of a powerful combined cycle plant: In a 2x1 combined cycle configuration, the power output is up to 180 MW(e) at a net plant efficiency of more than 60%.
In a combined heat and power (CHP) cycle, the efficiency is more than 92% with supplementary firing.

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 easily removed for maintenance.

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.
