If your plant suffers from frequent failures, installing additional thermocouples can prove to be invaluable when assessing the actual root cause of the failures.

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. In the US statutory inspections are mandated typically every year although some jurisdictions allow justification for longer intervals. Additional inspections are sometimes performed to establish the baseline condition of the HRSG (often early in life, but not always) or to perform less frequent special inspections to confirm component integrity.

Managing the Power Piping in CCGT Plants
Risk of failure and attendant personnel safety concerns are always present when operating highly-pressurized systems. Over the years, the occurrence of catastrophic events has driven improvements in construction codes and updated recommendations for O&M practices. As part of this trend, expanded requirements for operations and maintenance (O&M) were recently added to the ASME Code for Power Piping—ASME B31.1. The “Chapter VII Operation and Maintenance” was created in 2007 to prescribe guidelines that promoted early failure detection and overall safety. This was a fundamental change to the scope of B31.1, which up until then was strictly a design code; going forward, it now serves a dual purpose…
