Steam turbine and generator TOSHIBA 215 MW
new machine
215 MW Toshiba Inlet Steam Turbine &
Generator (Unused and well maintained)
New in 2008, this Power Plant has never been used and is available for
immediate inspection and delivery. Never having been used, the Plant
has no wear whatsoever.
The Steam Turbine:
Extraction & condensing, Inlet pressure: 104 bar, Output: 215MW
Extractions: MP2: 22 bar, MPI: 10 bar, LP: 4.5 bar, Feed Water: 0.4
bar
Minimum load: • No extractions, Only bleeds, Steam flow: 45 kg/s
Maximum load: Steam flow: 270 kg/s
The turbine is a Single Flow Extraction Condensing type. Steam
initially enters the steam inlet flange near the end of the high
pressure section and flows through the turbine stages toward the
generator end of the unit. After passing through the turbine stages,
the steam is exhausted to condenser. The exhaust hood is keyed to the
foundation plates at a point near its center of the exhaust hood to
prevent axial motion. The turbine expands axially from this point. The
front standard is free to slide axially but the standard and hood are
guided to prevent transverse movement.
Technical Specification of Steam Turbine & Aux type
a.) Single Casing Single Flow impulse type
b.) Condensing Turbine
c.) Rated Output: 188,000 kW at Generator terminal
d.) Speed: 3,000 rpm
e.) Rotation: CCW (viewed from front of Turbine)
f.) Last Stage Bucket Active Length: 42" (Nominal)
g.) Allowable Cycle Change: 48,5 - 50,5 Hz
The Generator:
250 MVA, Air to Water Cooled, 18 kV, 8019 A, 50 Hz, 3000 rpm
The generator consists of the stator, rotor, cover, bearing and
air-to-water cooler. The stationary armature is attached to and
supported by generator base. The rotor is supported by the bearings.
Air-to-water coolers are mounted above the stator. The cooling system
is completely enclosed to prevent exposure to dust and moisture.
Control Valve (CV) of Main Steam:
Steam, after passing through E4437227 the MSV, is admitted through
the CV to the high-pressure turbine. CV controls the amount of steam
passing to the turbine. It is opened and closed by an actuator and is
controlled by a Digital Electro-Hydraulic Control (D-EHC) system
through the turbine hydraulic system.
Storage Conditions:
Delivered 2009, currently stored indoors and secured, Turbine &
Generator completely sealed. Silica gel is inserted in the Turbine &
Generator and regularly replaced. Equipped with electronic monitoring
sensors for humidity & temperature with criteria from Toshiba for
storage, monitoring report generated monthly, inspection of unit every
(2) weeks, thorough Inspections were done every (6) months until 2012,
then yearly, inspection protocols.
