ADVANTAGES OF SGT6-5000F SIEMENS GAS TURBINES

SGT6-5000F SIEMENS GAS TURBINE

SGT6-5000F Longitudinal Section

CROSS SECTIONAL VIEW OFSGT6 500F SIEMENS TURBINE

ENGINE

Most powerful 60Hz F class engine capable of over 250 mw

High simple and combined cycle efficiencies

TURBINE

Turbine 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 SYSTEM

Emission Control and fuel flexibilityProven Ultra Low NOx (ULN) and Dry low NOx Combustion SystemSingle digit CO and NOx emission With 40 % turn-down capabilityMaintenance cycle increased from

8,000 equivalent base load operating hours to 12,500 hours

COMPRESSOR

High efficiency through proven 3D blading And abradable coating

Proven and robust 13-stage compressorNew sealing design was incorporated to

provide better leakage control over the complete operating range

Six Sigma methodologies were utilized throughout the development to

implement the technologies into a robust design.

ROTOR

500 units operating with single tie bolt rotors have Amassed 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.

ROTATING BLADES

All rotating blades Replaceable without Rotor de-stack or lift

Low firing temperature means low risk design with proven Conventional turbine alloys for longer Service interval and life

MAJOR OVERHAUL

HOURS-50,000 .STARTS- 1,800

VGV

Fast cycling capability through fast Acting variable guide vanes (VGV)

OPERATING HOURS

More than 500 units in commercial operation

More than 10 million accumulated operation hours

150 MW IN 10 MINUTES

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

SFC

Static frequency converter (SFC) (Static start, where generator

operates as a motor) replaced the mechanical starter motor. SFC allows more efficient and Faster rotor acceleration than the equivalently sized mechanical starting motor

TURNING GEAR

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

Extended Maintenance Intervals & Reduced Trip Factors

OTHER ADVANTAGES

Compressor 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
