General:
Boiler tube leak is always happened in power plant, which occupies over 60% in all incidents. Real time measurement boiler tube leak condition can give warning information at forepart of leak and give clue on the developing trend of boiler tube leak. It will greatly enhance the ability of an operator to predict the position and intensity of a leak inside the boiler. In this way, the operator can take some measures immediately to prevent the accident from worsening, reduce the time and cost spent on the repair.

Principle:
XLB automatic boiler tube leak detection device adopts acoustics measurement principle. According to boiler's characteristics, special sound sensor unit is set at corresponding position of boiler. Every sensor collects sound in boilers, and turns it into electric signal. Through an analysis of noise disturbance intensity and spectrum characteristics to judge if the boiler tube leaks.

Main function:
1. Real-time leak measurement and alarm ahead of time
2. Accurately judge leak location
3. Follow the leak growth trend
4. Real-time monitor of noise in a boiler
5. Auxiliary watch operation condition of ash blowers
6. Waveguide automatically clean ash

Products compositon:
1.System connecting way
2.distribution of measurement point

Application area:
It is mainly used in power plant boiler of thermal electric generation units to realize real-time measurement of forepart leak and effectively ash blowers measurement operation condition of water wall, reheater, superheater, economizer and heating surface.
