摘　　要：本文介绍了超声波氧化皮测厚方法在电站锅炉中的应用。同时,通过使用便携式氧化皮测厚仪对一台超超临界机组锅炉的高温受热面进行现场超声波氧化皮厚度检测,并将得到的数据与电厂监测的后台数据和实验室取样测量数据进行比较,证明采用超声波氧化皮测厚得到的测量结果是可靠的。通过这种方法可高效全面的了解锅炉运行情况,有效减少了锅炉爆管的风险,提高了设备的安全性和稳定性。The application of ultrasonic oxide skin thickness measurement method in utility boilers is introduced. At the same time, the high temperature heating surface of an ultra supercritical unit boiler was tested by using a portable oxide skin thickness gauge, and the obtained data are compared with the background data monitored by the power plant and the laboratory sampling measurement data, which proves that the measurement results obtained by ultrasonic oxide skin thickness measurement are reliable. This method can efficiently and comprehensively understand the boiler operation, effectively reduce the risk of boiler tube explosion, and improve the safety and stability of the equipment.
