1. Gas Turbine AlliedSignal ASE 40
1.1
General
Description
The
AlliedSignal gas turbine type ASE 40 is a cold-end drive engine designed for
stationary applications. The gas turbine incorporates innovative aerospace
technologies which have been well proven with the other members of the
AlliedSignal engine family:
Over 20.000
AlliedSignal gas turbine have accomplished more than 70 million hours of
world-wide operation, providing excellent reliability in demanding aerospace
and industrial environments.
The ASE 40
gas turbine has cold start ability allows it to reach maximum power within 45
seconds after starting.
The Gas
turbine when employed in stationary applications, is the basis of a very
compact generating set making it the perfect solution for co-generation
applications where the gas turbine module and heat recovery equipment need to
be integrated in the limited space of existing plants (e.g. boiler houses).
1.2
Design
features
The ASE 40
gas turbine comprises the following main components:
The gas
turbines inlet housing forms the main supporting structure and has 4
pads for pedestal mounting. All other main components are supported by the
inlet housing.
Mounted to
the underside of the inlet housing is the accessory gearbox which
provides vertical power take-offs for auxiliaries and a connection for the
starter motor.
The gas
producer module consists of the compressor with 7 axial and 1 centrifugal
stages and is driven by a two-stage axial turbine. The accessory gear box is
driven by the gas generator rotating group thorough bevel gears.
The combustor
is of the reverse flow annular chamber design utilising 28 fuel nozzles and
providing compactness, high efficiency and low emissions.
The hot end
of the engine consists of a two-stage axial flow power turbine and
related support housing. The power shaft runs coaxially through the compressor
rotor to the front end of the gas turbine where the power take-off is located.
2. Gearbox and Coupling shaft
Single
epicyclic gear for flange mounting to the generator. Reduction of the power
turbine speed down to 1500 rpm for 50 Hz applications.
The power
take-off of the turbine is connected to the gearbox via a high speed shaft with
membrane type flexible coupling and crowned spline connection to the gear.
3. Generator
Air-cooled,
brushless, synchronous medium voltage alternator in accordance with IEC 34,
equipped with two sleeve bearings, construction type B3, protection class IP
23, insulation class F, temperature rise acc. to class B.
with the
following features:
4. Generating set
The gas
turbine and the alternator / gearbox unit are rigidly mounted and aligned on a
common base plate.
5. Exhaust system
Exhaust
diffuser tailpipe in stainless steel, compensator and counter flange for
connection to the external exhaust system (heat recovery unit, silencer or
stack);
The
diffuser is connected to the soundproof enclosure with a flexible expansion
joint.
6. Fuel system
Pipework
internal to the module including gas fuel regulating valve, shut-off valves and
final filter. Flange connection to the customer gas supply system.
7. Combustion air system
2 stage air
cleaner acc. to class EU4 and EU7 mounted in the upper part of the soundproof
enclosure including anti-icing flap in the inlet air ducting, compensator
between filter housing and inlet plenum and stainless steel inlet plenum
designed for optimum air flow to the gas turbine compressor.
8. Start system
Hydraulic
starter motor mounted on the auxiliary gearbox of the gas turbine. The starter
motor is driven an hydraulic oil system internal to the module with tank,
electrical driven hydraulic oil pump, valves and piping.
9. Lube oil system for gear box and
alternator bearings
Lube oil
system including immersion type pump, oil cooler (air/oil), oil filter,
temperature control valve, pressure and level monitoring, air/oil separator and
preheater, completely mounted in the module.
10. Lube oil system for turbine
Lube oil
system including tank, oil pumps, oil cooler (oil/oil), oil cleaner, pressure
and level monitoring, completely mounted in the module.
11. Compressor Washing System (Off-line)
Wash water
injectors mounted on the engine, flexible hose for connection to an mobile wash
skid equipped with pump and tanks for wash solvent and water.
12. Soundproof enclosure
Soundproof
enclosure for noise attenuation to 85 dB (A) at 1m distance of the module,
including:
Noise
attenuation to 75 dB (A) at 1m available on demand.
13. Safety
The
enclosure is equipped with an automatic fire protection and gas detection
system, including:
The
detection of gas or fire in the module automatically generates an immediate
emergency shutdown, closing the external fuel shut-off valves.
14. Controls and Auxiliaries
Control
panel for installation near to the module equipped with PLC and local man /
machine interface panel mounted display with the following functions:
15. Documentation
Two sets of
manuals in English language for the scope of supply is available.
16. Testing and Acceptance
The main
components are factory tested and provided with approval certificates by the
suppliers.
