| Abstract: | This article explains the forming mechanism of oxide skin in inner wall of boiler tube in the ther- mal power plant, and expounds measuring principle and process of oxide skin in the heated surface. Some engineering applications that the oxide skin thickness of inner wall of boiler tube is measured by the ultrasonic technology are introduced. The results show that the ultrasonic measurement method can he used for inspection and maintenance of boiler tubes. |
