The turbine oil is cooled directly in the air heat exchanger.
Gas turbine lube oil cooling system.
However their waste energy is split between the exhaust lube oil system and jacket cooling system.
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.
Lube oil systems provide lubrication and cooling to gas turbines and other industrial equipment.
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.
Coolers are utilized on lubricating oil reservoirs of large rotating equipment to control viscosity and reject heat.
Alfa laval finned coil air heat exchangers are used to cool the turbine lube oil in power plants.
Common oils used in these machines have a viscosity of 32 centistokes cst.
The lubrication system usually consists of a large storage tank coolers to remove heat from the oil and pumps to circulate the oil.
In turbomachinery they are important for hydrodynamic bearing performance.
