The cooled gas generator turbine stator and rotor blades are precision-cast components.

Although the compressor section of the Siemens SGT-750 is of conventional horizontally split design, the remaining sections in the unit use single-piece, circular stator components arranged behind each other, thus avoiding any loss of circularity and reducing aerodynamic losses to a minimum. These sections can be removed as modules, which provides for easy access and simple maintenance.

The combustion chamber system for the 37 MW Siemens SGT-750 gas turbine consists of eight tubular combustion chambers with a double-walled serial-cooled design and eight double-walled transition ducts with parallel cooling.

Low Calorific and Waste Gas Stream

If you have a low calorific gas that cannot be used in a standard gas turbine or reciprocating engine, or have a difficult waste gas stream, then the KG2 with Power Oxidizer is the best available option.  This system can operate on virtually any waste gas stream eliminating the need for blending, the use of flares or other thermal oxidizer technologies, making power and heat energy with ultra-low emissions.

System features:

• Run fuels with gas energy levels as low as 50 Btu/scf
• Operate on a wide variety of fuels from 5% methane to 100% propane
• Is tolerant Hydrogen Sulfide and Siloxanes in most cases eliminating the need for pre-treatment.
