Boiler Leak Detection System

Acoustic Monitoring system uses the principle of collecting a variety of acoustic signals through a special furnace enhanced sonic sensor and converted into a current signal ; boiler operation on the basis of the elimination of the noise , the fast Fourier transform (FFT) analysis to give an acoustic signal spectrum , and displayed in bar graph form ; through noise intensity , spectral characteristics and duration analysis and calculation determine tube leaks occurred , and determine the extent of the leak and the leakage area location , so that power plant operators to take timely protective measures to prevent accident and shorten repair time and reduce economic losses.

System mainly consists of two parts :

1, The signal acquisition system ( including enhanced sensor and waveguide )

Enhanced Integrated Sensor
 
 
  • Reducing the local equipment interface
  • Simplifying the system architecture of the machine
  • Enhanced system reliability
  • Electromagnetic interference isolation site
 

Automatic ash coke waveguide

 


 Boiler to special conditions , suggested the use of electric -type waveguide , manual / automatic ; cast automatic boiler     combustion conditions should be based on the choice of a set time interval (1-30 days) , periodic cleaning to achieve the     waveguide decoke .
