SIEMENS GAS TURBINE SGT-200 1S:

DESIGN CONCEPT:
SGT-200-1S single-shaft turbine for Power Generation (up to 6.75 MW)The SGT-200-1S design is uniquely simple, employing a twin bearing gas generator, twin bearing power turbine and heavy duty casings. This allows full site maintenance to be carried out. The single shaft configuration provides excellent load acceptance and rejection characteristics, allowing robust and reliable operation in all applications. The gas turbine is available with a conventional or Dry Low Emissions (DLE) combustion system. Both systems provide dual fuel capability, the DLE system also providing extremely low NOx levels.



Power Generation Package

The SGT-200-1S is available as a factory assembled packaged power plant. It is easily transported, installed and maintained at site. The package incorporates the gas turbine, gearbox, generator and all systems mounted on a single underbase. Turbine controls, generator control panel, motor control center for package motors and variable speed drive for starter motor are normally also package-mounted.
