Article Preview

In plant, the main factor affecting power unit is the boiler, which mainly has the problem as unplanned outage caused by the leakage of water-cooled wall, superheater, reheater, economizer. So it is very meaningful and important to discover the problem of weak leakage of compression and heating surface of boiler and give the alarm in an early phase so as to figure out recondition method and reduce the recondition time. In this paper the deep research on acoustic features of background noise produced by boiler tube leakage and spectrum features of leak noise are presented to provide assistance for accurate location of the boiler leakage in the future.
