Description
Magdalena Palacz and three co-authors test fiber optic sensors for measuring strain in boiler hanger rods in this 2025 paper. Hanger rods carry the weight of industrial boilers, and their stress state guides maintenance. The standard check uses a hydraulic pressure pump, whose readings depend on operator judgment. The team fitted fiber Bragg grating sensors to a rod in a working facility. Such sensors read strain continuously, and the boiler need not shut down for a reading.
Side by side, the sensors gave steadier and more trustworthy data than the pump method. The sensors had served in structural monitoring before, but not on boiler rods. Continuous readings let operators watch stress build over time rather than sampling it at shutdowns. The authors present the approach as a diagnostic upgrade for estimating stress in industrial boilers. Better stress data should feed better maintenance timing.
