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 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. A report is generated every month to this day.
