Gas Turbine Lube Oil Cooling System

Common oils used in these machines have a viscosity of 32 centistokes cst.

Gas turbine lube oil cooling system.

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 lubrication system usually consists of a large storage tank coolers to remove heat from the oil and pumps to circulate the oil. The system assists in dissipating or settling contaminants providing for temperature fluctuations and storing oil. Lube oil cooler performance is impacted by a number of plant specific variables.

With the compact and reliable construction alfa laval finned coil air heat exchangers ensures optimal heat transfer of the turbine lube oil. Reciprocating engines like gas turbines run at efficiencies near 30. A single lubricating system is usually used for heavy frame gas turbines and driven equipment using mineral oil. 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.

In turbomachinery they are important for hydrodynamic bearing performance. Lube oil systems provide lubrication and cooling to gas turbines and other industrial equipment. The turbine oil is cooled directly in the air heat exchanger. Some applications use synthetic lubricating oil due to its fire resistant property.
