SGT-600 Industrial Gas Turbine
Power Generation: (ISO) 24.77 MW(e)
The SGT-600 is the most efficient and environmentally friendly industrial gas turbine in its power range. The robustness of the industrial design ensures high reliability and availability in all environments and applications.
The Siemens SGT-600 is a heavy-duty industrial gas turbine designed and built to meet requirements for low life-cycle cost, i.e. low first cost, low fuel costs and low costs for operation and maintenance. Low fuel consumption, even at part loads, and short installation and commissioning times are major features of this turbine.
In cogeneration and combined-cycle applications, the high exhaust temperature of the gas turbine makes it one of the most efficient units on the market. The SGT-600 is even able to perform durably in aggressive industrial environments under really tough operating conditions, whether onshore or offshore, in arctic or desert climate.
The outstanding reliability of the SGT-600 makes it ideal for interdependent multiunit applications.
A single-lift power generation module for floating platforms such as FPSO (Floating Production, Storage and Offloading) and semi-submersibles is available for both the SGT-600 and the SGT-700.
The SGT-600 uses a Dry Low Emission (DLE) system maintaining low specific fuel consumption in all applications.
The system is both stable and reliable, not requiring frequent recalibration, and coping easily with load changes, planned or otherwise.
