SGT-700 Industrial gas turbine

The SGT-700 features a third-generation dual-fuel Dry Low Emissions (DLE) combustion system:

NOₓ emissions level < 15 vppm
CO emissions level < 20 vppm
Turn down 50% load
Same DLE system for dual and liquid operation
NOₓ emissions on liquid fuels < 58 ppmvd
CO emissions on liquid fuels < 25 ppmvd
Turn down 50% on liquid fuels
Dual-fuel DLE capability with fuel changeover capability (gas to liquid fuel and liquid fuel to gas) on load

Packages for power generation and mechanical drive

The SGT-700 package offers you a small footprint and excellent serviceability. It features a modular and flexible design with single-lift capability.

The driver for both the power generation and the mechanical drive package is the same.

A gas turbine package includes:

Gas turbine, enclosure, base frame, air intake, exhaust, lubricating systems, starter system, vibration monitoring system, firefighting system, package ventilation system, instrumentation, gas detection, fuel systems, gearbox (if needed).

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.)
