SGT-700 gas turbine

SGT-700-based power plants

For combined cycle and cogeneration (combined heat and power – CHP), Siemens offers a broad range of power plant configurations and scopes based on the SGT-700 gas turbine. For combined cycle, 1x1 or 2x1 configurations are part of the standardized portfolio.

Excellent fuel flexibility

The SGT-700 offers best-in-class fuel flexibility that allows for high content of inert gases, hydrogen and heavy hydrocarbons:

• Ethane 100%
  
• Propane 100%
• Butanes and heavy alkanes 15%
• Hydrogen up to 55%
• Nitrogen 40%
• H₂S 3%

The SGT-700 requires low gas supply pressure at site: 28 bar(a) / 406 psi(a).
Fuel changeover (gas to liquid fuel and liquid fuel to gas) on load.

Low emission capability

The combustor and burner design give world-class emission performance over a wide load range and are capable of low NOₓ emission levels.
Low emission levels are also received on liquid fuel without need of water injection.

Emissions for 100 – 50% load, NOₓ at 15% O₂:

• Natural gas: ≤ 15 – 25 ppmv
• Diesel No. 2: ≤ 42 – 58 ppmv

Emissions for 100 - 50% load, CO at 15% O₂:

• Natural gas: ≤ 10 – 25 ppmv
• Diesel No. 2: ≤ 25 ppmv

(Emissions depend upon site conditions, required load range and other project-specific data.)
