METHOD AND SYSTEM FOR DIAGNOSISING LEAK POSITIONING USING ACOUSTIC EMISSION SENSOR IN BOILER

摘要

trace the leak location and leak detecting whether an acoustic emission signals caused by the leakage of industrial boilers A method and system is disclosed for. According to the invention there is provided a method for tracking the leakage phenomenon by using the acoustic emission signal generated from the boiler, (a) the structure of the inner plastic deformation and rupture boiler, mounted on the end of the wave guide at least one of the two euros leakage due to rupture sensing a first acoustic emission sensor and the acoustic emission signals from the second acoustic emission sensor to be mounted in a water-cooled wall, and (b) apply each time difference calculation method for comparing the sensed acoustic emission signal or a signal size, a combination The method comprises the step of tracking the location of the leak is provided in such a way that a particular internal structure. ; Thus, the present invention is compared to the calculated time difference with respect to the detected signal level or acoustic emission signal, for combining By way of a specific internal structure with the leakage location precision, to quickly track, the economic loss due to a time reduction can be achieved the effect of reducing significantly.
