Find Condenser Tube Leaks with Ultrasound

Identifying Condenser Tube Leaks with an SDT270 Ultrasound Detector

Case Study – AB Brown Power Plant, Mt. Vernon, Indiana

Executive Summary

Power Generation facilities aim to run at maximum output during uptime and manage downtime such that it has a minimal effect on efficiency.
Turbine efficiency is negatively impacted by tube leaks in the condenser. Leaks cause contamination of pure water used for steam. When contaminant counts reach alarm states pressure must be lowered reducing output. The turbine continues to run in a low capacity mode until the leaks are found and isolated.
Results Engineers must choose between:

  • Treating the symptoms with a system flush or
  • Fixing the problem by finding leaking tubes and plugging them, thereby removing them from service.

Hunting for Green Steam


Sustainability and Ultrasound Testing

The Paradox of Sustainability…

When manufacturers face uncertain economic headwinds, the word “Sustainability” can be a paradox.

In a good economy it’s fashionable to invest in green initiatives that promote  environmental sustainability. Reduce that carbon footprint. Conserve energy. Reduce waste. Sustainability under these circumstances paints a picture of responsible big business putting emphasis on the needs of community and planet first.

The paradox occurs when economic conditions turn south. Factories struggle to carve profits from their assets. Green initiatives no longer survive the budget cuts. In fact they are often the first programs to go.

Sustainability is redefined as “doing whatever it takes to keep the doors open.”

Ultrasound and the CBM Journey

Ultrasound CBM
Condition Monitoring with Ultrasound

Look beyond the acronyms and discover the true destination of your CBM journey.

Too philosophical for you? Then ask yourself, “what is the goal of any journey but to arrive at your destination?” Not any destination, YOUR destination. Yes… that means you need to know where you want to go before you leave the start line. Once your destination is locked in, defining the steps along the way becomes much easier.

Still not sure? I can help. Continue reading “Ultrasound and the CBM Journey”
