摘　　要：对流室炉管腐蚀是影响原油管式加热炉稳定安全运行的重要原因之一,采用声发射检测技术对不同腐蚀程度的对流室炉管进行了检测,通过对声发射信号各个参量数据的对比分析,得知不同腐蚀程度的炉管所测得的声发射数据有明显差别,相对于保压阶段,升压阶段的声发射数据对比度更为明显。验证了将声发射检测技术应用于原油管式加热炉对流室炉管腐蚀状态检测的可行性,为原油管式加热炉对流室炉管的腐蚀程度评价提供了一种新的思路和方法。Tube＇s corrosion in convection chamber is an important problem which has an impact on the se- curity of crude tubular furnace. Signal data of tube under different corrosion status is gathered and ana- lyzed by acoustic emission technique. There are significant difference in acoustic emission data which was measured by different degrees of corrosion drawn tubes through analysing the acoustic emission signals da- ta of various parameters, in constract of packing stage, acoustic emission data in suppress stage is more apparent. According to the detection results, the feasibility of acoustic emission technique used in tube＇s de- tection is proved and a new method which can be applied in the state evaluation of tube＇s corrosion is pro- posed.
