SGT-400 Industrial Gas Turbine Power Generation: (ISO) 12.

90 MW(e) Answers for energy. Industrial Gas Turbines The Siemens twin-shaft industrial gas turbine SGT-400 features a compact gas generator and a two-stage power turbine, incorporating the latest aero- dynamic and combustion technologies. The turbine has a simple-cycle efficiency of nominally

35 %. For industrial cogeneration, the high steam-raising capability of more than

27 tonnes per hour contributes towards achieving overall plant efficiencies of

80 % or higher. In addition, the compact arrangement, on-site maintainability and inherent reliability of the SGT-400 have made it an ideal gas turbine for the demanding oil and gas industry. Incorporating proven gas turbine technology, the SGT-400 offers cost- effective power for a wide range of duties, including: Industrial Power Generation Simple-cycle and combined-cycle power plants for base load, standby power and peak lopping Cogeneration for industrial plants with high heat load and district heating schemes Power Generation in the Oil and Gas Industry Offshore: on oil platforms and FPSO (Floating Production, Storage & Offloading) vessels Onshore: for oil field service, refinery application, emergency and standby power generation, Including highly efficient cogeneration solutions for oil and gas applications The SGT-400 combines very high efficiency (nominal

35 %) with excellent emissions performance in a rugged industrial design. This makes it the ideal choice for a wide variety of power generation applications. Key features High simple-cycle and cogeneration efficiencies, cutting fuel costs Dual-fuel Dry Low Emissions (DLE) combustion system, meeting stringent legislation Twin-shaft arrangement for both power generation and mechanical drive, allowing commonality of parts in mixed duty installations Maintenance Site maintainability or optional rapid core exchange as required by customer Designed for maintenance: - Horizontally split compressor casing - Horizontally and vertically split inlet casing - Combustion chambers, flame tubes and ignitors easily accessible for inspection - Large side-doors on enclosure for equipment change-out - Gas generator and power turbine removal on either side of package Multiple boroscope-inspection ports SGT-400 core engine test facility.
