Gas Turbine SGT-100
Power Generation: ISO 5.4 MW(e) / Mechanical Drive: 5.7 MW
Description
The SGT-100 is an industrial gas turbine with a power output range from 4.35 to 5.7 MW. It offers simple construction along with the latest technology in a compact package.
For industrial power generation, the single-shaft version of the industrial gas turbine SGT-100 is used in the following fields of application:
路 Simple cycle applications
路 Combined cycle applications
路 Combined heat and power (CHP)
路 Power generation for the oil and gas industry, on offshore platforms and FPSO vessels (Floating Production Storage and Offloading)
For mechanical drive, a twin-shaft version of the SGT-100 is a proven unit, primarily for the oil and gas industry. It is designed for applications where speeds and loads vary. The SGT-100 can operate over a range of different speed and load demands for the following applications:
路 Drive solution for pumping applications, including crude oil, other refinery product transmission and water injection
路 Drive solution for centrifugal compressors used in gas injection, pipeline transmission and boosting, gas processing and similar applications

Benefits
• Proven design resulting in high availability and security of supply
• Competitive cost-to-power ratio
• Excellent load acceptance and rejection characteristics, allowing reliable operation in all applications
• Dual-fuel Dry Low Emissions (DLE) combustion system, meeting the most stringent legislation
• Easy on-site maintenance or gas generator removal to workshop
• Alternate rapid core engine exchange option, minimizes downtime
 For power generation, the SGT-100 single shaft design is based on a single twin bearing rotor with heavy duty casings. This allows full site maintenance to be carried out.
For mechanical drive applications, a twin-shaft configuration of the SGT-100 provides excellent speed and load turndown flexibility. The design is uniquely simple, employing a single gas generator rotor with twin bearings and a single-stage overhung turbine. The free power turbine is a two-stage overhung design. Rotors are contained in heavy duty casings which are horizontally and vertically split, allowing full site maintenance to be carried out.
Both versions of the SGT-100 are available with Dry Low Emissions (DLE) combustion system, providing extremely low NOX levels with both gas and liquid fuels, as well as a full dual-fuel capability.
