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.

With the compact and reliable construction alfa laval finned coil air heat exchangers ensures optimal heat transfer of the turbine lube oil. Alfa laval finned coil air heat exchangers are used to cool the turbine lube oil in power plants. Reciprocating engines like gas turbines run at efficiencies near 30. Some applications use synthetic lubricating oil due to its fire resistant property.

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 system assists in dissipating or settling contaminants providing for temperature fluctuations and storing oil. However their waste energy is split between the exhaust lube oil system and jacket cooling system.

Coolers are utilized on lubricating oil reservoirs of large rotating equipment to control viscosity and reject heat. 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 turbine oil is cooled directly in the air heat exchanger. The lubrication system usually consists of a large storage tank coolers to remove heat from the oil and pumps to circulate the oil.
