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.

12.3Optional Features

12.3.1Enclosure Configuration

An enclosure can be selected to house both the gas turbine and driven equipment or only the gas turbine.

12.3.2Dual 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.

12.3.3Dust 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.

12.3.4Dust 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.

12.3.5Standby 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.

12.3.6Door 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.

12.3.7CO2 Fire Suppression System

The enclosure can be equipped with a CO2 fire suppression system consisting of a primary total flooding distribution system and a secondary metered distribution system to extend the design concentration of 37% CO2 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
