Boiler pressure pulsation measurement

A boiler (pressure) pulsation measurement can be made directly by using piezoelectric pressure transducers that are installed into the boiler wall, as seen in Figure 1. Boiler pulsation can also be picked up indirectly using accelerometers placed on the boiler wall, though this setup is limited when compared with the use of pressure transducers, as seen in Figure 2. Comparing the boiler pulsation measurements to known boiler data such as power, gas flow velocity, and so on allows for the assessment of root cause problems such a Vortex Induced Vibration (VIV) on heat exchanger pipes, acoustic...
