Technology

Robust and reliable design, high fuel flexibility, and low emissions

The SGT-750 is a low-weight industrial gas turbine designed and developed to incorporate size and weight advantages of the aeroderivative gas turbine whilst maintaining the robustness, flexibility and longevity of the traditional heavy-duty industrial gas turbine. With maximized uptime, top-class performance, and a low environmental footprint offering the customer high lifetime profitability, the SGT-750 is a perfect choice for the oil and gas industry as well as industrial power generation. The modular and flexible engine enables onshore or offshore applications, mechanical drive or heat and power. It combines a robust, reliable design with high efficiency and low emissions. The SGT-750 has a track record of proven and verified results after years in operation and several references in both power generation and mechanical drive applications such as pipeline and liquefied natural gas (LNG).

Highlights of the SGT-750 gas turbine

The SGT-750 features a specificially service-friendly design:

  • gas generator exchange within 24 hours
  • Easy access for boroscope inspection
  • Accessibility and modular design
  • Maintenance on-site in enclosure, or at local service workshop

The SGT-750 industrial gas turbine features a particularly favorable power-to-weight ratio. The SGT-750 uses proven design principles and combines the best and most reliable materials and components. As a result, the SGT-750 is a state-of-the-art gas turbine with minimal fuel consumption and extremely high availability.

With maximized uptime, top-class performance, and a low environmental footprint offering the customer high lifetime profitability, the SGT-750 industrial gas turbine is a perfect choice for the oil and gas industry as well as industrial power generation.

Applications for power generation:
Siemens offer a wide range of solutions for power generation, from stand-alone installations to complete power plants.

  • Gas turbine power plants (simple cycle applications)
  • Combined cycle power plants (combined cycle applications)
  • Combined heat and power (CHP) / cogeneration

Applications for Mechanical Drive
Siemens offer a full range of extended scope and turnkey solutions for mechanical drive applications. With decades of experience, we are able to design and implement any application, whatever the environment.

Compressor applications: Gas injection, gas processing, LNG , pipelines as well as other oil & gas applications

Pump applications: Water injection and fluid transmission projects

The SGT-750 has a track record of proven and verified results after years in operation and several references in both power generation and mechanical drive applications such as pipeline and liquefied natural gas (LNG).

SGT-750 core engine

The SGT-750 gas generator consists of a 13-stage axial air compressor with a rotor built from a number of fully electron-beam-welded disks. The cooled gas generator turbine stator and rotor blades are precision-cast components.
Although the compressor section of the SGT-750 is of conventional horizontally split design, the remaining sections in the unit use single-piece, circular stator components arranged behind each other, thus avoiding any loss of circularity and reducing aerodynamic losses to a minimum. These sections can be removed as modules, which provides for easy access and simple maintenance.

                     

SGT-750 core engine

 

 

        

The SGT-750 has eight burners and burns both liquid and gaseous fuels. The combustion chamber system consists of eight tubular combustion chambers. The system is suitable for both liquid and gaseous fuels. The tubular design provides for outstanding ease of maintenance and exchangeability.         

          


The SGT-750’s two-stage compressor turbine comprises the stator with guide vanes and the rotor assembly bolted to the compressor rotor. The first stage is cooled by a combination of internal convective cooling and film cooling.            

              


The SGT-750’s power turbine is a two-stage axial-flow turbine, aerodynamically connected to the gas generator. The nominal turbine speed is 6,100 rpm. In mechanical drive applications, the turbine speed range is 50 – 105% of the nominal speed.              

SGT-750 package

The SGT-750 is delivered as a complete package.
In a  module as carefully designed as the core engine, supporting systems and customized solutions interact to create an entity that delivers secured return on investment.

The modular build-up facilitates swift disassembly and parts replacement, and with a 24-hour engine swap time, downtime can be kept to an absolute minimum.

SGT-750 based power plants

PLACEHOLDER (SGT-800 text)

For combined cycle and cogeneration (combined heat and power - CHP), Siemens offers a broad range of power plant configurations and scopes based on the SGT-800 gas turbine. For combined cycle, 1x1, 2x1, or 3x1 configurations are part of the standardized portfolio.

Flexible scope

We can offer the scope according to your needs:

  • Package
  • Power train
  • Thermal equipment
  • Power island
  • Power block
  • Complete power plant

Flexible operations

SGT-800 power plants offers quick starts, fast load-following and low emissions on low plant part load. Designed for frequent starts and stops, the SGT-800-based power plant is perfectly suited as back-up to renewable power sources in the grid.

Excellent CC and CHP efficiency

Best-in-class combined cycle performance: In a 2x1 CC configuration, the power output is 153.7 MW(e) at a net plant efficiency of more than 56.7 %.
In a combined heat and power (CHP) cycle, the efficiency is more than 90 %.

Service-friendly design

The turbine is specifically designed for long operating times with extended overhaul intervals, and features easy maintenance, high availability, and outstanding reliability.
With extremely low downtimes for planned overhaul and maintenance work (only 17 days in 17 years), the SGT-750 achieves the highest availability in its performance class.

Maintenance features:

  • High availability with extremely low downtime for planned maintenance
  • Designed to be service-friendly
  • Fast gas generator exchange
  • Maintenance on-site or at local service workshop
  • Easy access for boroscope inspection

Component / module handling

The enclosure is equipped with a travelling overhead crane with 3.2 metric ton lifting capacity. The crane can be linked to the temporary external beam, allowing easy loading or offloading of a truck.

24 hours core swap-out capability
