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
