摘要
为了早期发现锅炉承压管轻微漏泄点，避免非计划停炉或起炉后再停炉，介绍了声谱分析法锅炉承压管漏泄检测技术。声谱检测法能有效区分漏泄声源和背景噪声。
In order to find out slight leakage in boilers,to avoid disarranged stopping of boilers or stopping of boilers just after they started,a detecting technology and monitoring system with acoustic spectrum on boilers bearing pipe are developed.The method can differentiate leakage sound source from background noise effectively.
