基于对电站锅炉高温受热面氧化皮堆积检测的工程需求,阐述了氧化皮生堆积致超温爆管的原因及磁性无损检测技术的原理。以两台锅炉的现场典型应用为例,介绍了氧化皮检测方法的流程。结果表明,该方法能有效检测氧化皮堆积,可将其作为日后电站治理和预防氧化皮堆积一种常规手段。 Based on the engineering requirements for scale buildup on high temperature heated surface of power station boilers, the reason of overfire tube explosion caused by oxide scale deposition and the principle of magnetic nondestructive testing technology are expounded. Taking the typical application of two boilers as an example, the procedure of the oxide scale detection method is introduced. The results show that this method can effectively detect the scale deposition and can be used as a routine measure to control and prevent scale deposition in future.
