Abstract
The reliable and trouble-free operation of the gas turbines is highly dependent upon the lubricating system and the lubricating oil performance. Recently the typical operating temperatures of turbine oils have been rising as modern gas turbines in power generation become more efficient. At the same time gas turbine oils are increasingly required to have longer service life. In order to fulfil all these requirements the current turbine oils need to possess adequate thermo-oxidation stability. However, as new quality of gas turbine oils have been introduced in turbine systems, new challenges appeared in regard of sludge, varnish and deposit formation. These contaminants and lubricating oil related problems led to downtimes, outages and extra maintenance costs. Due to clarify the reasons and backgrounds, extensive investigations and studies of the given thermo-oxidation stability problems are required for a better understanding of the complex phenomena.
