Design Concept

The modular, compact design of the SGT-500 facilitates easy on-site service – complete modules can be swiftly exchanged. The SGT-500 contains a twin-shaft gas generator: The low pressure axis contains a 10 stage low pressure compressor and a 2 stage low pressure turbine. The high pressure axis contains an 8 stage high pressure compressor and a 1 stage high pressure turbine. The three-stage power turbine speed is 3,600 rpm for power generation and 3,450 rpm for mechanical drive. In order to increase efficiency, a blade tip clearance adjuster is connected between the power turbine stator and rotor. 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.

SGT-500 Package

The SGT-500 is available as a factory assembled package. It is easily transported, installed and maintained at site. The package incorporates the gas turbine, gearbox, generator (for PG applications) 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.
