Remaining life assessment for boiler tubes affected by combined effect of wall thinning and overheating

Abstract: Boilers, the most troublesome components of electric power, chemical and processing plants generate high costs in unscheduled shutdowns, repairs and power replacement. Every occurrence of ruptured tubes leads to emergency shutdown of the entire plant. This paper describes the joint international effort to develop faster and more efficient methods for condition assessment and remaining life prediction for boiler tubes made of low-carbon steel. Authors have undertaken a systematic research with the major objecti… Show more

“…Therefore, efforts to identify the cause of this failure and its maintenance are critical. Superheater tube failures have been damaged in several similar power-generating units in the same area [7][8][9]. The superheater tube leaked and was partially bent during the maintenance shutdown, as shown in the picture below.…”

“…However, it is still difficult to measure the thickness changes of the tube due to the damages. The combination of the ultrasonic and electromagnetic field has been developed in the electromagnetic acoustic transducer (EMAT) system for the inspection of the water-cooled tubes [19,20]. The magneto-elastic phenomenon and Lorentz force help the EMAT inspect a deeper damage without the need for coupling material.…”
