Turbomachinery Package Specification

Titan 250 Generator Set

 

 

an AC source independent from the package power system. This independent power source is not provided by Solar.

11.3.3Dust 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.

11.3.4Dust 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.

11.3.5Standby 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.

11.3.6Marinization

Increased stiffening of enclosure structural components and additional flexibility of enclosure and flexible joints between the gas turbine and enclosure can be provided.

11.3.7Door 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.

11.3.8Fire and Gas System

Enclosed packages must include a fire and gas control system. The typical fire and gas system shown in Figure 22 provides gas monitoring, fire detection, and extinguishing agent release using an advanced distributed architecture to monitor gas, heat, and optical flame detectors. The system communicates with the Turbotronic 4 control system to initiate a shutdown if a fire or a high gas level is detected. On the package exterior, indicator lights, strobe lights, and an alarm horn provide system status. A keyswitch is provided to inhibit the system and a push button switch is provided to manually release the fire-extinguishing agent.

The primary fire detection system uses multi-spectrum IR (MIR) flame detectors. The system includes an automatic optical integrity feature to provide a continuous check of the optical surfaces, detector sensitivity, electronic circuitry of the detector-controller system, and automatic fault identification with digital display of system status in numerical code. The secondary detection system consists of rate-compensated thermal detectors. The two detection systems act independently in detecting and reporting a fire. The number of detectors may vary depending on the enclosure configuration.

The fire system control panel provides system supervision (for open circuit, ground fault, or loss of integrity), initiates alarm and release of fire suppression agent, and visual display of system status. The suppression system agent release is activated automatically with release solenoids located on the fire suppression skid. The optional

CO2 or water mist suppression system can also be activated manually by switches 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.
