  System Principle
Utilize Acoustic principal, we made special enhanced sound sensor to collect the sound signal inside the furnace of the boiler. The sound signal can then be converted to current signal using FFT to convert it to spectrum display. Using the bar graph display to view the signal strength, frequency characteristics and continuous time observation, tube leak can be determined.
  System Structure

Reduce local installation;
Simplify system structure;
Enhance system reliability
Isolate local EMC interference.
Auto or Remote Manual Soot Clearing: 
The computer enable to set auto soot clearing 
once every day, 3 days, 7 days, 10 days and 
15 days. This soot clearing period depends 
on the type of coal burnt and type of boiler.
