The sensors are mounted like soot blowers in a defined
space throught the furnance area.When a leakage occurs
(first being the pin hole leakage), the sound comes in a
definite frequency range. The sensors mounted detects only
this frequency and eleminates all other sounds being
produced inside furnance which are of differnt frequencies.
the signal then transmitted to RTU and from where it is fed
to DCS console. Note that you can only find the location
not the exact tube/coil no. Once you find the leakge
zone,secondary damages cen be avoided. Now this package is
included in all boliers from BHEL.
