When a power plant faces an unplanned outage, the losses can run into the hundreds of thousands of dollars per day. That was the case for a critical power plant in Central America when one of its units had a damaged rotor. Thanks to Laborelec’s quick reaction and technical expertise, a long and risky repair process was avoided. Here’s an account of how this issue was addressed.

Unexpected cracks are found in the rotor blades and shrouds during a routine maintenance inspection. The original equipment manufacturer (OEM) is charged with investigating the issue.
Identifying appropriate techniques and parameters
T24 material has a high susceptibility to stress corrosion cracking. As it is used in the boiler evaporator sections of ultra-supercritical (USC) power plants, reliable repair techniques are needed. Laborelec and Fabricom conducted a research program to determine the most appropriate repair techniques and parameters. This resulted in a series of recommendations…
