Boiler Tube Leak Detecting System
This system uses high-sensitivity acoustic sensors to detect and identify boiler tube leaks at an early stage, which may be caused by clinker fall-induced tube damage, manufacturing or welding defects, ash cutting due to combustion gas vortex action inside the furnace, localized overheating, or thermal degradation over time. By detecting leaks early, it prevents secondary and tertiary damage propagation of boiler tubes.
