MISTRAS-Triple 5’s AMS has a specific application for HRSG Heat Recovery Steam Generator (HRSG) tube leak detection. HRSG Online Monitoring with the AMS provides 24-7, real-time data that offers first detection, as well as leak location and trending, capabilities at least two weeks earlier than traditional methods, which fall short because of a HRSG’s unique operational challenges, and with hundreds of thousands of dollars in potential savings. By detecting an acoustic change in normal background noise and providing first notification, HRSG Online Monitoring can: secondary damage; manage power market risk; trend leak progression and severity; schedule maintenance vs. forced outage; preplan jobs to maximize efficiency and optimize outage.
