Failure of Titanium Condenser Tubes After 24 Years Power

Aug 26, 2014 · The titanium condenser has been in operation for 24 years at Amager unit 3 power plant. In February 2012, the plant was contaminated by seawater due to a failed condenser tube and some tubes were plugged. A month later, the plant tripped again. Small leaks were found again and finally approx. 200 tubes were plugged before the condenser was in service again.

Failure investigation of super heater tubes of coal fired

Oct 01, 2017 · Failure of super heater tube of boiler is the major concern of forced outages at coal fired thermal power plant. Flue gas passes over super heater tubes leading to damage over the time of operation and termed as fireside damage/corrosion. Again the extent of damage is dependent on quality of coal, materials used, operation and maintenance.

Corrosion Fatigue in Boiler Tubes – Thielsch Engineering

Oct 28, 2018 · In the early 1980s, the Electric Power Research Institute (EPRI) identified 22 mechanisms that could result in the failure of a boiler tube. One of those mechanisms involved corrosion fatigue. At that time, this mechanism was not well understood. Moreover, there were no permanent solutions to address this mechanism. In 1992, approximately 10 years after…
