Gas Turbine and Auxiliaries
Gas Turbine
General description
The PG9171(E) GT package was developed by a GE/ EUROPE authorized licensee with the
frame 9E as basic equipment and within the license agreement with General Electric Co.
(USA).
The PG9171(E) is a single shaft, high efficiency gas turbine for power generation in 50 Hz
grids, suitable for simple cycle and combined cycle application.
The engine is designed for 3000 rpm nominal speed, to be directly coupled to a two-pole
synchronous electric generator. This gas turbine unit includes all features and design solution
coming from the operating experience of the MS9000 family, whose evolution has brought to
the PG9161(E) one of its highest reliability value. The PG9161(E) unit consists of three
compartments, one housing the auxiliaries, one the gas turbine itself, and the last one housing
the exhaust plenum. Each compartment is equipped with access doors for easy site inspection
and maintenance. The rotor is a single shaft assembly consisting of one compressor rotor
joined to one turbine rotor by a flanged joint, and lays on three journal bearings (two elliptical
and one tilting pad type). Two thrust bearings; one Kingsbury type (loaded) and one tilting pad
type (unloaded) are also provided.
Compressor
The compressor rotor consists of 17 stages with 12.3/1 overall compression ratio. The
compressor rotor consists of 15 wheels, shrunk onto a forged shaft (rotor stages 2nd to 16th), two
stub shafts (1st and 17th rotor stages), 16 tie bolts and stator/rotor blades. The stationary blades
are assembled into two half rings (diaphragms) for each stage; the diaphragms are fitted into the
compressor casing. The rotating blades are fitted on the discs by dove-tail roots and fixed by
means of pins. The compressor external casing is totally made of grey cast iron. The compressor
front portion contains the Inlet Guide Vanes (IGV) device that allows modulating the inlet flow
during start up and optimize performance at part load operation. Air bleed ports provide cooling
air for 1st and 2nd turbine stages (stationary and rotating buckets). The compressor end portion
that discharges the air mass flow into the combustion chamber contains the compressor diffuser,
devoted to eliminate flow swirl and then improve diffuser efficiency.
Combustion Section
The PG9161(E) combustion system has been designed in order to ensure reliability, durability
and flexibility, even in case of using different fuels. The combustion system is contained in a
carbon steel casing which is part of the compressor-combustor shell and provides housing for
combustor wrapper, combustions chamber assemblies, fuel nozzles, spark plug ignitors, UV
flame detectors, cross flame tubes, transition piece. The combustion takes place in 14
combustion chambers, circumferentially arranged around the machine axis. The hot gas flows
from the combustion chambers toward the turbine section via 14 "S" shaped transition pieces.
This special arrangement ensures a good mix between the film cooling air and the combustion
gases, thereby optimizing the gas temperature pattern at the first turbine stage inlet. The
combustion section consists of Hastelloy cylinders joined together with corrugated rings, which
lead the cooling air film along the wall, thus improving cooling.
The combustion chambers are installed and removed without lifting the combustor casing
cover, in order to facilitate inspection and to reduce the inspection time. The transition pieces
connecting the combustors to the turbine inlet are manufactured with NIMONIC 263 alloy,
which yields good anti-corrosion properties together with high cracking resistance, and is
furthermore easily weld able for maintenance at site, without needing heat treatment. Spark
plug igniters, located in the 10th and 11th combustion chambers, are used t ignite the fuel/air
mixture; the remaining chambers are ignited through cross flame tubes that provide connection
between every two adjacent combustors. Two ultraviolet (UV) flame scanners, located in the 4th
and 5th combustion chamber are provided to detect ignition during start up. The fuel is injected
into the combustion chambers through fuel injectors, one per each combustion chamber, which
are provided for single fuel operation.
Turbine
The 3-stage turbine rotor is constituted by 3 discs, forged in alloy steel and coupled each other
by bolted connections.
All rotating blades are precision cast, and are attached to the wheels by straight, axial-entry,
multiple-tang dovetails that fit into matching cut-outs in the rims of the wheel. The turbine
stationary blades (nozzles) are precision cast according to the following table:
- first stationary row 18 segments x 2 vanes Cooled
- second stationary row 16 segments x 3 vanes Cooled
- third stationary row 16 segments x 4 vanes Uncooled
The cooling flow for the cooled profiles is bled from suitable compressor stages (see
compressor section). The space between 2nd and 3rd rotor wheels is also cooled by compressor
bleed air. Nozzle diaphragms are attached to the inside of both 2nd and 3rd stage nozzle
segments. These diaphragms prevent air leakage past the inner sidewall of the nozzles and the
turbine rotor. A turbine shroud is included, whose main function is to provide a cylindrical
surface for minimizing bucket tip clearance leakage (a secondary function is to provide a high
thermal resistance between the hot gases and the comparatively cool shell). This reduces the
shell-cooling load and allows controlling the shell diameter and roundness and turbine
clearances. The shroud segments are maintained in the circumferential position by radial pins
from the shell. Joints between shroud segments are sealed by interconnecting tongues and
grooves.
Exhaust Frame and Exhaust Plenum
The flanged end of gas turbine shell is bolted to exhaust frame. On the structural point of view,
the frame consists both of an outer and an inner cylinder, interconnected by radial struts. The
GT end journal bearing is supported from the inner cylinder. The exhaust frame, fabricated in
ASTM A435 carbon steel, receives gas flow from the GT diffuser, and is connected to the
exhaust plenum by flexplate expansion joint.
The exhaust plenum consists of a box, open at one side and welded to its own base. It is
fabricated in carbon steel, lined with 409 SS chromium steel sheet. Thermocouples for
measurement of exhaust gas temperature and for transmitting the values to the GT control
system are located in the final part of the exhaust plenum.
Gas Turbine Control System (SUMIVAC)

The Gas Turbine includes the following auxiliaries:
• Oil Systems (Lubricating Oil system, Control Oil system)
• Inlet Air system (Filtration system, Inlet Air duct, etc.)
• Exhaust Gas facilities (silencer, vertical stack)
