Abstract

This study conducted a failure analysis of the condenser tube in unit 1 of the Tenayan Steam Power Plant. It started from the inspection in the first year after the commercial off date (COD) where there is a leaky tube, so there is further suspicion. Various tests and analysis are carried out such as tube vacuum testing, Eddy current testing, condenser tube material analysis, condenser water quality analysis, effectiveness and heat transfer on a condenser to the determination of root cause failure analysis to ensure condenser performance. From the results obtained, the cause of the failure of the condenser tube in unit 1 is the thinning of the condenser tube wall. The failure mechanism is erosion corrosion caused by the use of water in condensers that contain high turbidity.
