Gas Turbine Lube Oil Cooling System

With the compact and reliable construction alfa laval finned coil air heat exchangers ensures optimal heat transfer of the turbine lube oil.

Gas turbine lube oil cooling system.

Reciprocating engines like gas turbines run at efficiencies near 30. Lube oil systems provide lubrication and cooling to gas turbines and other industrial equipment. Lube oil cooler performance is impacted by a number of plant specific variables. The turbine oil is cooled directly in the air heat exchanger.

In turbomachinery they are important for hydrodynamic bearing performance. Gas turbine combined lube and control oil in gas turbine power plants lubrication of the bearings on the turbine shaft main roller journal thrust bearings keeps the turbine running at its optimum. The system assists in dissipating or settling contaminants providing for temperature fluctuations and storing oil. Some applications use synthetic lubricating oil due to its fire resistant property.

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. The lubrication system usually consists of a large storage tank coolers to remove heat from the oil and pumps to circulate the oil. However their waste energy is split between the exhaust lube oil system and jacket cooling system.
