Its success proves us right

Since its market launch in 1993, the SGT6-5000F has

demonstrated world class reliability. An operating fleetof 320 turbines with cumulative fired hours exceedingten million and a fleet reliability of consistently99 percent speaks for itself. The SGT6-5000F’s worldclass reliability is achieved through proven technology,low F-class firing temperatures, and the use of conven-tionally cast alloys in the turbine. Despite its low firingtemperature, the SGT6-5000F packages deliver high-level efficiency. However, the SGT6-5000F excels notonly in worldwide service, but also with remarkableperformance parameters. Best of all, as the core packagecomponent, the SGT6-5000F also influences the equallyexceptional performance of the packages in simple cycle

as well as combined cycle applications.

Versatility you can count on

The SGT6-5000F is the basic component in numerous

different concepts in the area of fossil electricity genera-tion. In the 60 Hz market, it is the first choice for simplecycle and combined cycle operation with or withoutintegrated gasification combined cycle (IGCC), combinedheat and power (cogeneration), and repowering.The 13-stage high efficiency compressor and four-stage

turbine are on one central tie bolt rotor with Hirthserration. The SGT6-5000F is designed to use a widerange of different fuels. It runs on natural gas, lowor medium calorific BTU gas, as well as on distillate oils –and there is no need to shut down the turbine whenswitching from gas to liquid fuel.

Flexibility that enables you to react withmaximum efficiencyThe need for flexible power generation has increased

dramatically over the years. The SGT6-5000F is the rightchoice to meet those ever-changing energy demands.The unique turbine design is always biased towardhigh efficiency values. But in applications where powerhas the absolute top priority, we can rapidly increasepower output by an additional ten percent with ShapingPowerTM – this provides operating flexibility to respondto changing grid demands without impacting part life.

And to provide even more flexibility the SGT6-5000F withShaping PowerTM can also operate in “max efficiency”mode with reduced fuel consumption.

The SGT6-5000F achieves short and cost efficient start-uptimes thanks to the fast start option. You can producepower for the grid in five minutes and generate 150 MWin ten minutes from turning gear speed. While connected

to the grid, the gas turbine can ramp at 30 MW/min –with no service penalty. The low load turndown optionprovides you with the flexibility to reduce load down to

< 40 percent of gas turbine base load while maintainingemissions compliance. This gives you the benefits ofremaining cost effectively connected to the grid withreduced fuel costs during off-peak hours, while alsoavoiding start-up and shutdown costs. You are thereforeable to respond more quickly to changing grid demands.

You can always rely on the SGT6-5000F for consistentperformance with low emissions and high flexibilityin operation.

Environmental friendliness that allows you

to set benchmarks

With nine ppm NOx without water injection and less thanfour ppm CO, the SGT6-5000F boasts the lowest emissionvalues today. We achieve this through the Ultra Low NOx (ULN) combustion system.

Air intake system

Ambient air is guided and filtered to thecompressor inlet with an option for a self-cleaning (pulse) filter with automatic dustremoval. Inlet air conditioning options areavailable that include evaporative coolingand inlet chilling for increased output onhot days. Inlet heating options are avail-able for extreme cold environments.

Exhaust gas system

Exhaust gas is guided from the gas turbinevia the diffuser to the turbine plant’s stackor to a combined cycle plant’s heat recoverysteam generator (HRSG). A bypass stackoption is available for combined cycleplants for switching between combinedcycle mode and simple cycle mode duringoperation.

Auxiliaries – the ideal equipment

to round out the package

We pay attention to the details. We not only offeryou the core components for flexible and efficientpackages, we also provide the auxiliaries necessaryfor economical and reliable operation. To minimizefield work during assembly and maintenance, theauxiliary systems and associated piping are designedand manufactured to allow easy access and require

Electrical system

The electrical package contains equipment necessaryfor sequencing, control, and monitoring of the gas turbine

and generator. This includes the gas turbine control system,motor control centers, generator protective relay panels,fire protection system, battery bank, battery charger,and dry-type transformers.

Oil systems

The oil systems consist of a lube oil (LO) package and ahydraulic oil power unit (HPU). The LO package providesclean, filtered oil for lubricating and lifting the gas turbineand generator bearings, and provides lubrication for theturning gear. The LO skid consists of the lube oil reservoir,LO pump, and lift oil pumps and provides a support struc-ture for the LO cooling system (fin-fan air or water cooled).

An all-weatherproof lube oil enclosure option is availablefor cold or dusty environments. The HPU provides medium-pressure hydraulic oil to operate the gas fuel stage throttlevalve, the inlet guide vane actuator, and the variable guidevane actuators.

Starting system

The starting system consists of an air cooled static fre-quency converter (SFC) and a turning gear system. Theturning gear can be remotely and automatically operated.The turning gear system rotates the rotor at 120 rpmduring shutdown to facilitate a uniform cooldown.

During start-up, the turning gear rotates the rotor toremove bow and facilitate a smooth start. The turninggear also provides the breakaway torque to accelerate

the gas turbine to the speed needed to engage the SFC.The SFC accelerates the gas turbine to ignition speed, andafter successful ignition the SFC will assist in acceleratingthe unit to rated speed.

Compressor water wash skid

The compressor water wash skid is provided for onlineand offline compressor cleaning. It features an AC motor-driven pump, piping, valves, strainer junction box, cabling,flowmeter, and detergent storage tank. Everything isassembled on a portable skid for greater flexibility.

Enclosures

The gas turbine is housed in an enclosure with easydisassemble/assemble walls for quick engine access.

Fire protection

The fire protection system gives a visual indication ofactuation at the local control panel. The fire suppressantsystem provides total protection of the turbine enclosureand the electrical control package.

There are many other options available to meet yourproject specific needs.
