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.

Alfa laval finned coil air heat exchangers are used to cool the turbine lube oil in power plants. Lube oil systems provide lubrication and cooling to gas turbines and other industrial equipment. In turbomachinery they are important for hydrodynamic bearing performance. 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. Lube oil cooler performance is impacted by a number of plant specific variables. 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. Some applications use synthetic lubricating oil due to its fire resistant property.

With the compact and reliable construction alfa laval finned coil air heat exchangers ensures optimal heat transfer of the turbine lube oil. Coolers are utilized on lubricating oil reservoirs of large rotating equipment to control viscosity and reject heat. A single lubricating system is usually used for heavy frame gas turbines and driven equipment using mineral oil. The turbine oil is cooled directly in the air heat exchanger.
