Ultrasonic Flowmeter Reveals Reason for Tube Failure in High-Heat Application

A major power generator was having a premature tube failure in the feed water heater of its 400 megawatt pulverized coal plants. The nature of the problem seemed to be: hot spots in the water wall and inconsistent water flow. To test their theory they measured the temperature of the hot spots, but measuring the flow of the return water was harder. They did not want to cut into the pipe and the return water was steam condensate under pressure, with temperatures running around 650°F. The issues continued when they discovered air in the line, damaged tubes, and uneven flow. The solution: FLEXIM’s WaveInjector designed to combat high temperatures.
