BASIC PACKAGE: Solar T-60 ( B.O.M )
The Taurus 60 Industrial Power Generator (IPG) is a compact, rugged gas turbine generator set that has been designed to meet the requirements for industrial and utility power generation applications. The unit is provided as a completely integrated module ready for installation. The gas turbine engine, gearbox, generator, control system, fuel system, lubrication system, start system, and ancillary equipment needed for site operation on natural gas are included with each unit.
Each package includes a sound attenuated enclosure for the turbine generator and a PCR control building to house all generator and turbine control functions.
Approximate overall dimensions are: 32 feet, 0 inches (9753 mm) long 8 feet,
0 inches (2438 mm) wide.
Approximate height of package is 10 feet, 8 1/4 inches (3258 mm) and may vary
with ancillary equipment and generator selection. Four lifting gussets are
provided on each section.
Drip pans are welded beneath the package frame to collect potential liquid
spills. The drip pans also provide a tight seal for containment of fire
suppression agent for packages supplied with an enclosure.
Tube Fittings. All tube connections use compression fittings. Tubing and
fittings are 316 stainless steel. Piping. Package piping is designed and
fabricated to ANSI B31.3.
ELECTRICAL SYSTEM
The Taurus 60 IPG generator set is designed to comply with the requirements
of the National Electrical Code. Unless otherwise noted package motors and
heaters are rated for 460 VAC, 60 Hertz, 3 phase. Motor space heaters are
provided for motors over 5 hp (3.75 kW) and are rated for 120 VAC, 60 Hertz, 1
phase.
Fire Detection and Suppression System. The gas turbine enclosure will be
provided with ultra violet fire detectors and fire monitoring system. The fire
suppression system agent is C02. In the event of a fire being detected within
the unit, the unit will shutdown, the enclosure ventilator louvers will close,
and horns will sound. Gas Detection System. Gas detection monitors are provided
in the turbine enclosure. Upon detection of 20% LEL, alarms will sound. Upon
detection of 75% LEL, the unit will shut down and all louvers will open, and all
ventilator fans will activate.
GAS TURBINE ENGINE
The Taurus 60 gas turbine engine is a single shaft axial flow engine. The output
gearbox, including accessory drive pads, is a separate, close-coupled unit
located at the inlet end of the turbine. The engine assembly consists of: Gear
unit with accessory drive pads. Air inlet collector with flexible flange
connection. Axially split case in the vertical plane, eleven-stage axial flow
compressor with variable temperatures. Geometry control on inlet guide vanes and
first two rows of stators Annular SoLoNox combustor with 12 lean premix fuel
injectors. Three-stage turbine assembly, Turbine exhaust collector.
The components of the Taurus 60 engine are maintained in accurate alignment by
mating flanges with pilot surfaces and are bolted together to form a rigid
assembly. The speed-reducing gearbox is driven by the compressor rotor shaft.
Accessory pads drive the main lube oil pump and other accessories, depending on
the application, and support the starter motor. The gas turbine
output shaft is mechanically connected to both the compressor and turbine
sections of the engine to form a "solidor "singleshaft configuration.
This feature enhances speed stability and response under constant and varying
load conditions -- a highly desirable feature in generator applications
requiring precise frequency control.
SPEED REDUCING GEARBOX
The speed-reducing gearbox is an industrial design manufactured by Solar
specifically for the Taurus 60 IPG generator set. The gearbox mounts directly on
the Taurus 60 gas turbine to reduce engine speed to 1800 rpm (60 Hz).
