Figure 11. Typical Lube Oil System8.1.7Lube 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.

8.1.8Lube Oil System OptionsLube 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.
