ADVANTAGES OF SGT6-5000F SIEMENS GAS TURBINES

ENGINE: Most powerful 60Hz F class engine capable of over 250 mwHigh simple and combined cycle efficiencies

TURBINETurbine stage 1 design has new aerodynamic, cooling,Coatings and materials design, Stage 2 includes improved cooling, materials and Coatings technology and Stages 3 and 4 utilize new coatings technology. The fourth Stage vane and blade designs contribute to improved efficiency and increased maximum Shaft power limit

COMBUSTION SYSTEMEmission Control and fuel flexibilityProven Ultra Low NOx (ULN) and Dry low NOxCombustion SystemSingle digit CO and NOx emissionWith 40 % turn-down capability

COMPRESSORHigh efficiency through proven 3D bladingAnd abradable coatingProven and robust 13-stage compressor

ROTOR500 units operating with single tie bolt rotors haveAmassed over 12 million hours and 149,000 starts.No nickel-based alloys are used in the rotor construction; rather the rotor uses upgraded steel discs in the turbine section, allowing for greater flexibility in turbine blade cooling air temperature

MAJOR OVERHAULHOURS-50,000 .STARTS- 1,800

Fast cycling capability through fastActing variable guide vanes (VGV)

All rotating blades Replaceable without Rotor de-stack or liftLow firing temperature means low risk design with provenConventional turbine alloys for longer Service interval and lifeMore than 320 units in commercialMore than 500 units in commercial operationMore than 10 million accumulated operation hours

A Fast start option is available to produce 150 MW in 10Minutes

Static frequency converter (SFC)(Static start, where generator operates as a motor) replaced the mechanical starter motor. SFC allows more efficient andFaster rotor acceleration than the equivalently sized mechanical starting motor

Turning gear (TG) speed was increased from 3 rpm to 120 rpm

OTHER ADVANTAGESCompressor technology development,Combustion system development,Cooling and leakage air reduction,Cooling and disc cavity air modulation,Improved thermal barrier coating (TBC) application on some turbine airfoils,Selected turbine vane and blade improvements,Blade tip clearance reduction, andExhaust system enhancements
