Turbomachinery Package Specification
Taurus
60 Compressor Set and Mechanical Drive
mounted on the gas turbine enclosure or at the suppression skid. If a fire is detected, the
fire detectors transmit an electrical signal to the fire system control panel to activate the
fire alarm and suppression system
.
The enclosure is also equipped with two gas detectors: one at the gas turbine enclosure
ventilation air inlet and the other at the ventilation exhaust to provide continuous
monitoring of combustible gases. The detectors consist of IR hydrocarbon sensors that
provide input to the logical operating network (LON) module. The gas turbine start signal
is interlocked with the combustible gas monitoring system to ensure the atmosphere is
safe prior to initiating a turbine engine start. An alarm is initiated if the gas monitor fails.
12.3 Optional
Features
12.3.1 Enclosure
Configuration
An enclosure can be selected to house both the gas turbine and driven equipment or only
the gas turbine.
12.3.2 Dual Fan Ventilation
The enclosure can be ventilated with a dual AC motor-driven fan system. The fan motor
wiring is terminated at the motor junction box. Openings are provided to ensure adequate
airflow is circulated through the enclosure. For Conformité Européenne (CE) Mark
certification, the second or backup ventilation fan is mandatory and must be powered by
an AC source independent from the package power system. This independent power
source is not provided by Solar.
12.3.3 Dust Protection System
The enclosure ventilation inlets are equipped with a single-stage, disposable, barrier-type
filter unit equipped with a differential pressure alarm switch. The ventilation exhaust
openings are equipped with back-draft dampers to prevent the entry of dust when the unit
is not running.
12.3.4 Dust and Moisture Protection System
The enclosure ventilation inlet can be equipped with a two-stage filter unit consisting of a
first-stage vane separator and a second-stage filter. The moisture eliminator section is
hinged for filter access. The unit is equipped with a differential pressure alarm switch and
gauge. The ventilation exhaust opening is equipped with back-draft dampers to prevent
the entry of dust and water when the unit is not running.
12.3.5 Standby
Lighting
Standby lights provide emergency, automatic, and backup lighting inside the enclosure in
the event of an AC power loss. Power is supplied from the package battery system. To
avoid battery system drainage, the circuitry includes a shutoff timer.
12.3.6 Door
Open
Alarm
The enclosure doors can be equipped with a door position switch that will initiate an
alarm when any enclosure door is not closed securely.
12.3.7 CO
2
Fire Suppression System
The enclosure can be equipped with a CO
2
fire suppression system consisting of a
primary total flooding distribution system and a secondary metered distribution system to
extend the design concentration of 37% CO
2
for 20 minutes.
On fire detection by the optional fire and gas detection system, the detectors transmit an
electrical signal via the fire control panel to activate the fire suppression system release
