Gas Turbine Lube Oil Cooling System

Approximately 48 of the waste heat is in the exhaust stream 27 removed by the lube oil system and 25 removed by the jacket cooling system.

Gas turbine lube oil cooling system.

The lubrication system usually consists of a large storage tank coolers to remove heat from the oil and pumps to circulate the oil. Lube oil systems provide lubrication and cooling to gas turbines and other industrial equipment. Some applications use synthetic lubricating oil due to its fire resistant property. The system assists in dissipating or settling contaminants providing for temperature fluctuations and storing oil.

Common oils used in these machines have a viscosity of 32 centistokes cst. A single lubricating system is usually used for heavy frame gas turbines and driven equipment using mineral oil. Reciprocating engines like gas turbines run at efficiencies near 30. Lube oil cooler performance is impacted by a number of plant specific variables.

However their waste energy is split between the exhaust lube oil system and jacket cooling system. In turbomachinery they are important for hydrodynamic bearing performance. Coolers are utilized on lubricating oil reservoirs of large rotating equipment to control viscosity and reject heat. With the compact and reliable construction alfa laval finned coil air heat exchangers ensures optimal heat transfer of the turbine lube oil.
