Acoustic Instruments may be used to detect early boiler tube leak to avoid secondary damage to pressure parts.Boiler acoustic tube leak detection system must be used as it prevent damage to costly boiler parts and it is very much cost effective.An increase in boiler availability of just one day will more than cover the cost of a leak detection system.
Traditional leak detection system such hearing hissing sound by ear or monitoring feed water flow or furnace vaccum is not much reliable because it can not detect small leak so damage to vital costly equipment of boiler may not be avoided.Writer noticed many instances where thermal power plants boiler allowed to run for long time due to confusion which caused permanent damage to many boiler tubes,refractory and boiler structures.Hence importance of acoustic monitoring leak detection systems sincerely felt .
Acoustic leak detection sensors detect high frequency emmissions from site of leak and Sensitive piezoelectric sensors mounted to the structure transform these acoustic waves to electronic voltage signals, which are amplified, filtered, and processed to determine energy content.
Early detection by acoustic monitoring instruments results in substantial reduction of repair times and costs with a consequent increase in plant availability and profits. The early detection of a bolier tube leak will give financial savings which will easily exceed the initial capital cost of the detection system even at the very first event.
Finally,Acoustic monitoring instruments must be intalled in boilers of thermal power plants.for more details go to
