Reliable, robust, and flexible power generation

The SGT6-2000E gas turbine is a proven, robust engine for the 60 Hz market, used in simple cycle or combined cycle processes, with or without combined heat and power. It is suitable for all load ranges, including peak load, and offers outstanding fuel flexibility: You can use low calorific gases or gases containing CO₂, H₂S and N₂ or crude oil and other liquid fuels with high viscosity. In addition, it provides low NOₓ emissions, even in the part-load range.

Highlights of the SGT6-2000E gas turbine

The extensive fleet operating experience of the SGT6-2000E lets  you benefit from best-in-class fleet reliability of > 99%. Its robust turbine design is continuously enhanced by high-performance upgrades.

Thanks to its fast start-up capability, you will achieve full load in only about 10 minutes. With its fast load change capability, in turn, you will meet the most stringent grid requirements for optimal frequency stabilization.

The SGT6-2000E offers dual-fuel capability and excellent fuel flexibility: It can be fired with low calorific gases or gases containing CO₂, H₂S and N₂, as well as with crude oil and other liquid fuels with high viscosity.
It provides reliable start-up and changeover between fuels. The automatic changeover from the primary to the secondary fuel can be carried out at reduced base load.

This robust engine is suitable for a wide range of ambient conditions such as cold climates, hot and dry or dusty environments.

For hot and dry conditions, we offer these options to increase your power output:

  • An evaporative cooler or an inlet air chiller with heat exchangers to avoid performance degradation
  • A Wet Compression (WetC) system to enhance turbine performance by reducing compressor inlet temperatures and increasing the mass flow throughout the turbine

The SGT6-2000E is designed for easy maintenance to reduce outage times:

  • Rotor de-stacking/ re-stacking on site
  • Blades can be individually replaced without rotor lifting
  • Vane carriers can be removed without rotor lifting
  • Minor inspections can be done through the spacious combustion chambers

Ingenious design to the core

The SGT6-2000E core engine has a horizontally split casing and two walk-in combustion chambers, equipped with individually replaceable ceramic tiles. This design allows a hot-gas-path inspection without cover lift. The 17-stage axial-flow compressor with variable-pitch inlet guide vanes enhances peak load operation and supports frequency stabilization.

The robust 4-stage turbine incorporates the latest blade and vane design for stable, improved performance. The hybrid burners are able to operate in premix and diffusion mode with natural gas, fuel oil and special fuels such as heavy oil and refinery residues. The Low-NOₓ combustion system, single-digit NOₓ emissions can be achieved.

Short installation times

The SGT6-2000E gas turbine package consists of the core turbine, the generator (SGen6-100A-2P) and auxiliary systems. It offers you a standardized basic design with options geared to your specific requirements. By using standard components and pre-assembly or pre-packaging we achieve short installation times, with staggered delivery and early shipment of main components. We group subsystems and install them in separate auxiliary packages to minimize field assembly.

The SGT6-2000E fires up

We offer both simple cycle and combined cycle power plants with or without cogeneration.
SGT6-2000E-based combined cycle plants (SCC6-2000E) have a fast-start capability. You can achieve combined cycle base load within only 8.5 min for start-up until full load with a startup gradient of 27 MW/min. High load gradients allow for fast load changes. With excellent peaking capability, and high part-load efficiency complying with emission regulations down to lower part load, this is your profitable solution for competitive energy markets with fluctuating power demand.

Optimized for short outages to maximize availability

We offer Long Term Programs (LTP), overhaul services, field service, spare parts, reconditioning of components and modernization upgrades. Whether scheduled service or short-term support, our specialists are there for you, on-site all over the world.

The SGT6-2000E generator package is optimized for short outages. Multiple borescopic inspection ports allow inspection of compressor and turbine blades without lifting covers. The heat shields on the combustion chamber are individually replaceable. All stationary and moving blades and all stationary blade and vane carriers can be replaced individually with the rotor in place.

Fuel flexibility matters

The SGT6-2000E offers outstanding fuel flexibility: It burns natural gas, LNG, syngas, blast furnace gas, biogas, ethane, propane, condensate, distillate oil, heavy and crude oils, bio-diesel, alcohols, naptha or kerosene.

The gas turbine can also be fired with low calorific gases or gases containing CO2, H2S and N2, as well as with crude oil and other liquid fuels with high viscosity.

Low emissions

The SGT6-2000E provides low NOₓ emissions, even in the part-load range or using liquid fuels.
NOₓ emissions at 15% O₂ dry:

  • Emissions on fuel gas at 15% O2, without water injection: NOX ≤ 25 ppmvd | CO ≤ 10 ppmvd
