Inspection is part of routine maintenance for any Heat Recovery Steam Generator (HRSG). Visual inspections are performed at regular intervals in accordance with the requirements of regulatory bodies and insurers.
During the startup of the triple-pressure HRSGs, plant staff noticed steam coming from the stack and a discrepancy between feedwater and steam flows. On shutting down the unit a T23 superheater tube was found with a complete circumferential failure. The failed tube was removed and the bore was plugged with some difficulty due to poor access and the uncommon material.
Two of the most common issues that power plant owners and operators face in the HP Evaporator section areUnder-deposit Corrosion (UDC) andCorrosion-Fatigue. In this short article we will cover UDC and what key actions should be taken to predict and prevent costly forced outages.
