Cost Benefits of Critical Valve Repair in the Heat Recovery Steam Generator

Modern advance frame combined-cycle power facilities operate in a dispatch environment where cold starts, accelerated ramp rates and low load conditions are the norm and where Balance of Plant (BOP) equipment accounts for more than half of all forced outages. An analysis by Pentair revealed that valves are a significant contributing factor in forced outages, primarily based on their application numbers and the severity of their service applications. This article focuses on small bore vent valves and drain valves, reporting research findings that repairing these valves is more prudent and economical than replacing them.
