Figure 11. Typical Lube Oil System
8.1.7 Lube Oil Vent Flame Arrestor
The lube oil vent flame arrestor prevents an ignition source from entering the lube oil
tank. The flame arrestor is loose shipped for offskid installation by others.
8.1.8 Lube Oil System Options
Lube Oil Cooler
An air-to-oil type cooler is available to provide oil cooling for the gas turbine and the
driven equipment. The cooler is sized for specified heat loads and ambient temperatures
and is designed for a 4.4°C (40°F) approach temperature. The cooler is loose shipped for
offskid installation by others.
Lube Oil Immersion Tank Heater
The lube oil tank immersion heater ensures the lube oil tank temperature is adequate for
starting in cold conditions. The tank heater also facilitates a short lube oil temperature
warm up period after a cold start. Electrical supply contactors are not included.
