Failure Analysis of Tube Burst of Screen Superheater in Power Plant Boiler
Boiler must be shut down when boiler tube bursts,which is the main factor causing the unplanned outage of the power generation system.This poses a serious threat to the reliability of the plant,also causes huge economic losses.The failure analysis of the burst tube of the screen superheater in a petrochemical plant shows that the longer term overheat of screen superheater tube is the root cause of the explosion.Based on this,it is of great significance to take targeted measures to avoid pipe explosion to reduce unplanned outage.
