MS6001FA – details extracted
MS6001FA (6FA) gas turbine is the mid-size model in GE’s family of F-class gas turbines , the world’s largest, most experienced fleet of advanced technology gas turbines.  A 2/3 scale of the 7 FA gas turbine, the 6 FA produces 70 megawatts (MW) of simple cycle power at 34 percent efficiency, and 110 MW of combined cycle performance gas turbines for moderate electrical capacity additions and combined heat and power applications.

● Applications:
● 50 or 60 Hz
● Simple cycle, combined cycle, integrated gasification combined cycle
● Single-shaft or multi-shaft combined cycle configurations
● Base load power generation
● Co-generation and district heating

MS6001FA Design Features

The MS6001 FA (6FA) gas turbine is a 0.69 aerodynamic scale of the 7FA utilizing the principles of aerodynamic similarity and geometric sealing.  GE has sealed down the size of the proven 7 FA components while maintaining their aerodynamic similarity.  Critical design parameters such as temperatures, pressures and stresses remain constant between the scaled 6 FA and parent 7 FA and 9 FA designs.

The one area where geometric scaling was not employed in the 6 FA is the combustion system.  Here, the number of combustors, rather than the physical size was scaled.  The 7 FA uses 14 combustors.  The 6 FA uses six combustors with approximately the same flow per combustor as the large machines in the F product family.

By sealing a proven advanced technology design and combining it with advanced aircraft engine cooling and sealing technology, GE has incorporated into the 6 FA lessons learned from nearly two million fired hours of operation.  The 6 FA also incorporates the modular, packaged design characteristics of the proven GE MS600B, allowing power-train components to be shipped assembled for both 50 Hz and 60 Hz applications.

Axial Compressor

The 6 FA Gas Turbine has an 18 stage axial flow compressor with modulating inlet guide vanes.  The first two stages are designed consistent with advanced high by pass ratio aircraft engine fan glades, which reduce shock losses.  The pressure ratio is 15 to 1 interface air extraction inlet for cooling and sealing air for turbine nozzles, wheel space, and bearings, and for controls during startup.

Compressor Features Include:

● Axial/radiate inlet casing, Scaled from the 7 FA i.e. proven design provides uniform inlet flow to the compressor.  Up or side inlet configuration are available.
● Bearings, Cabling pad journal and thrust bearings provide superior rotor stability and load distribution
● Compressor Blading. Scaled from the proven 7 FA design, C- 450 and AISI 403 plus C’s alloys, eliminate the need for coating.  Variable first stage veins provide efficient part load operation.
● Compressor Casings.  The mid casing is designed with radical symmetry for improved compressor blade and vain clearance control.  The discharge casing struts facilitate transition piece removal.
Forward Support.  Its rigid design limits thermal expansion of the gas turbine toward the load gear.
● Wheel construction.  The wheels are machined to nearly coolant stress cross section with contact faces at maximum diameter for high rotor stiffness.
● Rotor Construction.  Through hold design at maximum hold circle, the rotor construction provides rigidity and high torque capability.  The first bonding critical harmonic occurs well above the rated speed.
● Stator Casting Design.  All castings are split on horizontal centerline with through boiled horizontal and vertical joints to facilitate maintenance.

Combustion System

The 6 FA combustion system is comprised of six chamber; they are similar in design and operating conditions to those of the 9 FA because the flow per can in the 6 FA is within 2 percent of the 9FA.

A further improvement of the 6 FA combustion systems is the integrated multiple of first stage nozzle vanes with number of combustors.  This provides for a repeatable, chamber-to-chamber thermal distributed going into the first stage nozzles.

Dry flow NOx and Integrated Gasification Combined Cycle Combustion ( IGCC) Systems are available. Both are capable of multi-fuel applications – natural gas, distillate oil, propane and fossil fuels.  Dry low NOx is the standard offering Integrated Gasification Combined Cycle Combustion (IGCC) is an option for using a wide spectrum of low heating value fuels, including gasified coal or heavy oil and steel mill gases.

The combustor liner cap incorporates multiple fuel nozzles to reduce both combustion wear and inspection intervals.  A plastic-spray thermal barrier coating is applied to the liner’s surface to embrace high temperature strength and reduce metal temperatures and thermal gradients.

Combustion System Features Include:

Reverse flow combustion chambers.  Six individual combustors of 7 FA/9FA design enable each nozzle and liner to be inspected and maintained without disassembling the turbine.

● Transition piece.  A separate performed sleeve around the transition piece enable the body exterior to be effectively cooled with compressor discharge air.  Internal surfaces have a thermal barrier coating.

Turbine Section:

The 6 FA Turbine operates with the temperatures and stress levels us the performance-proven 7 FA and 9 FA designs.  The turbine section consists of three stages with air cooling provided to all three nozzles stage and to the first two bucket stages.  All airfoil and rotor cooling is provided through internal cooling circuits, climmating the possibility of material from external filters and coolers to plug the airfoil cooling passages.

All 6 FA turbines buckets us GE’s STD-111 alloy, which provides superior structure strength, low cycle fatigue strength, and collision resistance.  First stage nozzles are cast from GE’s cobalt base alloy, which provides superior oxidation resistance and weld ability.  Second and third stage nozzles are cast from GTD-222, which provides Turbine section features include:

● Nozzle.  The sidewalls and internal surfaces of vanes are impingement-cooled with spent air used for extensive firm cooling.
● First stage stationary sound.  Its two-stage design with an inner segment of coated high temperature alloy is extensively convection, impingement and film-cooled for tight bucket tip clearances.
● Buckets.  The first stage bucket has a directionally solidified grain structure with turbinated serpentine cooling passages and tip and trailing edge bleed.  The second stage bucket has tabulated radial cooling holes.  The third stage bucket is un-cooled. The last two stage buckets have integral Z lock shrouds for vibration control and reduced tip leakage. All bucket stages have long shanks for vibration control and isolation of gas path temperatures from the turbine wheels.
● Rotor Design.  Three wheels are separated by spacers with a forward distance piece and a bearing shaft.  Rotor segments are bolted together to form a rugged rigged structure with flexing well above the operating speed.
Internal passages distribute cooling air to appropriate wheel and air foil locations.

Controls

The reliability of GE’s F technology gas turbines is further enhanced by the redundancy built into our state of the art Speedtronic Mark V control system.  This micro processor-based turbine control vs. distributed processor design and a redundant architecture, resulting in overall performance unmatched in the industry.  The Mark V uses independent controllers to achieve the reliability of triple redundancy for turbine control and protection.  A PC-based color graphic operator interface displays control and monitoring status and executes operator commands from logical, uncluttered screens.  In combined cycle applications, we integrate the Mark V with the plant controls, providing the industry’s optimum control solution.

All models with 3 pressure reheat steam cycle, ISO base rating (lower heating value), and natural gas fuel.

Emissions.  GE is the leader in dry low NOx emissions with more than 200 installed at power plants worldwide.  Because of the higher specific output of F-Class machines, less NOx and CO are emanate per unit of power produced for the same exhaust concentrations. F systems have succeeded in meeting or exceeding the site requirements of every project in which they have been applied.  6 FA gas turbines employ DLN-2 combustion technology, which can achieve NOx emissions levels of 25 ppm or less.

MS6001 FA Advantages

High efficiency.  In simple cycle applications using natural gas as fuel the MS 6001 FA (6FA) delivers an efficiency rating of 34.2 percent.  In combined cycle configuration, it delivers 53 percent net efficiency.  This high efficiency is driven primarily by high firing temperatures.  In IGCC applications, the 6 FA can achieve gross efficiency as high as 46 percent.

Application Flexibility

The gear-driven 6 FA meets the need for mid-size power blocks with high performance in combined heat and power applications.  Its output range, high exhaust energy, full packaging, and robust design make it ideally suited for a wide variety of application ranging cogeneration and district heating to pure power generation in combined cycle and IGCC (Integrated Gasification Combined Cycle).

Fuel Flexibility

Like other F technology units the 6 FA can burn a wide spectrum of fossil fuels, including gasified coal.  You can switch fuels after start-up without sacrificing performance.

Reliability and Availability

GE introduced the 6 FA Gas Turbine in 1993, and the first unit entered commercial service in 1999.  To date, eight units are operating because of the short service time.  No operating data has been collected; however, our modeling program suggests these machines will attain an average running reliability of 99.0 percent, and an average starting reliability of 96.5 percent.  The performance levels of specific machine depend on their equipment configuration, fuel, and service duty.

Lower Fuel Costs 

The high efficiency of the 6 FA leads to substantial fuel cost savings in base load combined cycle operation over earlier mid-range machines,

Fast Installation and Startup

Building on its Frame 6, 7, and 9 installation experience, GE developed modularized packaging system to assure fast installation with minimum installation cost.  Modules are skid-mounted adjacent to the turbine to minimize interconnection complexities.  All accessory modules houses equipment for lube oil, hydraulic oil, gas fuel, and generator seal oil systems.  A liquid fuel/atomizing air module houses the equipment that delivers liquid fuel to the turbine.  Electrical components are also housed in packaged modules.  All modules are arranged for ease of maintenance and clean plant layout.
