The system of acoustic detection and location for the leakage of boiler pipelines is increasingly being applied in the boilers of power plant.The system uses acoustic technology not only to detect the leakage in the furnace pipeline,but also to locate the position of the leakage by the multi-microphone positioning method.As a result,it can effectively reduce the unscheduled downtime caused by pipeline leakage,which is particularly important to a power plant.In this paper,the key technology of the system is analyzed,and the current status of application presented.Finally,some directions of improvement are proposed.
