The three shaft industrial gas turbine SGT-500 is a light weight, high efficiency, heavy duty machine. It operates reliably in the 15-20 MW power range and can handle a variety of fuels. For both, industrial power generation and mechanical drive, the SGT-500 is a proven unit. The SGT-500 is available as a factory assembled package and provides an excellent power-to-weight ratio. Moreover, the SGT-500 has successfully undergone a comprehensive test program on heavy fuel oil for marine applications. 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.
