Investigation of Thrust Bearing High Temperature in Gas Turbine

Fathi Al Jabri, S Feroz

Abstract


Gas turbines in electric power generation and various industrial applications has made remarkable improvement in the current scenario in terms of size, efficiency and prominence. In order to maintain the sustainability of high level performance and increased reliability of the gas turbine, it has become mandatory to carryout in depth diagnostic methods and frame maintenance plans. This paper mainly concentrates on the analysis of the repeated tripping of gas turbine in Oman oil industry, due to its thrust bearing high metal temperature issues. Root cause analysis, visual and borescopic inspections, lube oil analysis were carried out to indentify the root causes for high temperature and came up with successful results for restoring and ensuring reliable operation of gas turbine.
