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.
