SGT5-2000E Heavy-duty gas turbine (50Hz)

The SGT5-2000E gas turbine is a proven, robust engine for the 50 Hz market used in simple cycle or combined cycle processes with or without combined heat and power supply. It is suitable for all load ranges, including peak load. The SGT5-2000E offers outstanding 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.

This heavy-duty gas turbine provides low NOx emissions, even in the part load range. Today, more than 315 turbines have been sold, resulting in a fleet experience of over 33 million equivalent operating hours. The SGT5-2000E series fleet´s overall best-in-class reliability constantly exceeds 99.5%.

The SGT5-2000E 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. The engine, equipped with DLE burners, is capable to burn up to 30 vol% of hydrogen (H₂).
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

Ingenious design to the core

The SGT5-2000E 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 16-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. With the Low-NOₓ combustion system, single-digit NOₓ emissions can be achieved.

Short installation times

The gas turbine package for the SGT5-2000E consists of the core turbine, the generator (SGen5-100A-2P) and auxiliary systems. We offer you a standardized basic design with options geared to your specific requirements. By using standard components and preassembly or prepackaging 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 SGT5-2000E fires up

Simple and combined cycle power plants, including optional cogeneration, are available. SCC5-2000E plants with SGT5-2000E turbines can reach base load in under 12 minutes, ramping up at 30 MW per minute. Their high load gradients allow fast power adjustments, providing strong peaking capacity and efficient performance at partial loads, meeting emission standards even at lower outputs. These features make them well-suited for competitive markets with changing energy demands.

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 SGT5-2000E 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 SGT5-2000E offers outstanding fuel flexibility: It burns natural gas, LNG, syngas, blast furnace gas, biogas, ethane, propane, condensate, distillate oil, heavy and crude oils, biodiesel, alcohols, naphtha or kerosene.

The gas turbine can also be fired with low-calorific gases or gases containing CO₂, H₂S and N₂,or with up to 30 vol% of hydrogen (H₂), as well as with crude oil and other liquid fuels with high viscosity.
