Prevent unplanned shutdown from the boiler tube leakage

Introduction video of Boiler Tube Leakage (BTL) detection.

In the coal fired power station, it equip with large quantity of the boiler tube and the reliability requirements of them are operation critical. Once the boiler tube leaks, it will directly affect the safe and economic operation of the generator set. Therefore, the prevention of boiler tube leakage and the early detection and treatment of leakage are becoming increasingly important for power generation companies.

Especially in the CFB boiler has high abrasion to the boiler tube due to circulating of sands and volatile turbulence flow.

Benefits of Boiler Tube Leakage Early Detection System

  • Early detection of boiler tube leakage so that damage will be minimized
  • Advanced notice of leak problems to minimize costs of damage and repair
  • Controllable downtimes for repairs to lower operation replacement costs (Planned shutdown for repair)

Solution – Automatic Boiler tube leakage early detection system

We provide the Automatic Boiler tube leakage early detection system that gives an early warning of the leakage of boiler tube upto small leaks less than 1mm.

Principle of Operation

Using the principle of acoustic monitoring, various acoustic signals are collected from the furnace and converted into current signals. The detection and alarm system analyzes the spectrum of the acoustic signal by fast Fourier transform technology (FFT) and displays it in the form of a bar graph. The analysis of noise intensity, spectral characteristics and duration determines whether the boiler tube leaks.

Advanced leakage monitoring system features the precise location monitoring, self diagnostic, long term trending and alarm features.

Acoustic Sound Sensor & Soundguide Tube

Soundguide tube install along the boiler wall and Acoustic sound sensor pickup the sound around the boiler. typically 20-30 sensors are installed for one system, depends the site of the boiler.

Typically specification of sensor.

    • Sensitivity: >25mV/Pa can detect small leaks <1mm, alarm 2~3 days earlier than the usual method
    • Detection range: radius ≤ 12 meters hemisphere space
    • Working temperature: -25 ° C ~ +105 ° C
    • Continuous running time: > 30,000 hours
    • Power supply: single power supply, DC+12V lower power consumption, lower voltage drop
