Dear Sirs
subject to prior sale we
can offer
1.) 12.5 MW complete Biomass Power Plant
Manufacturer: Westinghouse Turbine
and Generator (1953 vintage), Zurn Boiler
(original boiler
at construction)
Year of Construction: Facility in
1983
Running hours: It ran at
approximately 93% to 97% capacity from 1983 to 2002
Location: USA
TURBINE-GENERATOR - SPECIFICATIONS
CLASSIFICATION: 1953 Westinghouse
Condensing, Extraction, Impulse Turbine driving a Two-pole AC Generator at 3600
RPM.
UNIT RATING: By design, the
limitation of the turbine-generator unit is the limitation of the prime mover -
the turbine. Thus, maximum output is 12,650 Gross KW.
TURBINE RATING - STEAM
PRESSURE: 600 PSIG
STEAM TEMPERATURE: 825 degrees Fahrenheit
STEAM FLOW: 125,000 LB/HR
EXHAUST PRESS.:
1.5 Hg
KILOWATTS: 12,650 kw
STEAM VARIATIONS
PRESSURE: The initial steam
pressure at the turbine throttle valve inlet shall not exceed 600 psig average over a 12 month period of operation at rated load.
At reduced load the average should not exceed 630 psig. Absolute maximum inlet
pressure in abnormal situations is 780 psig (aggregate duration of this
pressure not to exceed 12 hours per 12 month period).
TEMPERATURE: The initial steam
temperature at the turbine throttle valve inlet shall not exceed 825 F average over a 12 month period. Absolute maximum inlet
temperature in abnormal situations is 875 F (at this temperature, limit is 15
minutes duration per swing and aggregate duration not to exceed 80 hours per 12
month period).
GENERATOR RATING -
VOLTAGE: 12,500 AC
AMPERAGE : 625
POWER FACTOR: .85
FREQUENCY: 60 Hertz
KVA 13,529
EXCITER RATING -
VOLTAGE: 250 DC
AMPERAGE : 260
TURBINE INFORMATION
THROTTLE VALVE: The throttle valve is
hydraulically operated to control the flow of steam to the turbine during
start-up. Turning the valve wheel repositions a valve that controls the flow of
high-pressure oil into the operating cylinder. The operating cylinder is used
in conjuction with the low oil and overspeed trips on the unit.
STEAM CHEST: The turbine governor controls
the steam chest first stage nozzle valves. The valves seats are of the diffuser
type. Partial-load operation is more efficient this way due to the reduction of
throttling losses.
BLADING: 1 - CURTIS (VELOCITY COMPOUNDED)
13 - IMPULSE
3 - PAIRS OF ROWS OF REACTION BLADING
The major
difference between impulse and reaction blading is
the shape of the blades. By design, impulse blading
gets a pressure drop, and thus work, accross the moving blades only. The fixed blading,
or diaphragms serve only to redirect the steam. With reaction blading, there is a pressure drop accross
the fixed and moving blades. Therefore, reaction blading
is usually used in the low pressure end of a turbine before entering the
condenser. Although work is done across fixed and moving blading,
reaction blades are less efficient than impulse.
EXTRACTIONS: There are four extractions on
this turbine for heat exchanger and gland seal supply steam. For more
information, see Specs - Boiler / Steam
ROTOR GLANDS: The glands are of the
Labyrinth-type. Multiple spring-back seal rings maintain very close clearance
to the turbine rotor. Steam at approximately 1 psi is supplied to the high and
low pressure glands to further seal the clearances. The gland at the low
pressure prevents air from leaking in. The gland at the high pressure end
prevents steam from leaking out.
GENERATOR INFORMATION
A generator has three requirements: 1) A
magnetic field, 2) a conductor, and 3) relative motion between the two to cut
flux and produce electricity. The Bio Energy generator consists of two
generators. The exciter which produces DC power and the generator which
produces AC power (an AC generator is also called an alternator). The generated DC voltage of the exciter, (usually in the 100 - 150
DC V range at 120 - 170 DC A), supplies the magnetism to the generator 2-pole
rotor. The stator, or stationary windings, of the generator are the
conductors.
A General Electric current limiting
reactor is installed to prevent the destructive flow of energy that may be
caused by a short circuit or overload. A multitude of realys
are also interlocked to protect the generator and exciter from abnormal
conditions.
Cooling for the generator is provided by
two water cooled heat exchangers that run the length of the unit on both sides.
The exciter and collector are cooled by a shaft driven fan which takes suction
and discharges to the area below the unit.
