摘　　要：电站锅炉管道泄漏的声检测与定位系统,主要利用声学技术检测炉内管道的泄漏状态,并利用多传声器定位机理对泄漏点进行定位,有效地减少了由管道泄漏引起的非计划停炉。分析了该系统的关键技术,介绍了其发展概况及应用现状,提出了改进方向。The system of acoustic detection and location for the leakage of boiler pipelines can detect the leakage in the fumace pipelines with acoustic technology and locate the postition of leakage by multi-microphone postitioning mechanism.As a result,it can effectively reduce the unscheduled downtime caused by pipline leakage.Then the key technology is analysed and current application is introduced.Finally proposals for further development are presented.
